Warning
Additional Safety Instructions for Hydraulics

1. HYDRAULIC INJECTION HAZARDS. Be familiar with the hazards of hydraulic injection injuries.
   • Leaking hydraulic fluid may have enough pressure to penetrate skin.
   Never use your hands to check for suspected hydraulic leaks.
   • Hydraulic fluid that is injected into skin is a medical emergency that may cause infection, disability, amputation or death.
   • The average injection injury may be a small wound that has barely broken the skin. DO NOT be fooled by this type of injury. Immediately get to an emergency medical facility!
   • Minimizing the time between the injury and when the injected mate- rial is removed is critical to minimiz- ing the seriousness of the injury.

2. EYE PROTECTION. Safety glasses may not always protect your eyes from hot, pressurized fluid. The best way to protect yourself is to stay away from leaks until you can depressurize the system.

3. HYDRAULIC LEAKS. Stop the machine if you notice a hydraulic leak. Allowing the machine to continue running with a leak may increase the hazard of the situation and damage the machine.

4. CHECKING FOR LEAKS. Use a piece of cardboard to check for suspected hydraulic leaks. Pressurized hydraulic fluid may cause injection injuries and can be extremely hot. Never use your hands to check for suspected hydraulic leaks.

5. DEPRESSURIZE FOR MAINTENANCE. Depressurize the hydraulic system before attempting any maintenance or service. Stop the resaw, open the conveyor speed valves, and make sure the pressure gauge reads 0 PSI.

6. INSPECTIONS. Regularly inspect and perform maintenance on the hydraulic system.
   A well-maintained hydraulic system will have much fewer problems and hazards than a neglected system.

7. CLEAN MAINTENANCE AREA. Make sure any hydraulic system maintenance is performed in a clean and dust-free work area. Remove any sawdust, grime or water from hydraulic system openings or components before maintenance. Always use lint-free rags when wiping components.

8. COMPONENT REPLACEMENT. Only use high pressure hydraulic hose and steel hydraulic fittings when replacing components in the hydraulic system. DO NOT use brass or aluminum.

Never use a larger circuit breaker than stated below, or you will increase the risk of fire.
Circuit Breaker……………………………………30 Amp
Minimum Wire Requirements
For 440V 3-phase operation, use the following type of wire:
Wire………………………………………. 10 GA. Copper
We recommend running THWN/THHN grade insulated wire through rigid conduit and hardwiring into a locking power disconnect. Consult a licensed electrician for information on local and national electrical codes.

Connection Type
Because of the high amperage draw from this machine, we recommend that you hardwire it directly to your circuit breaker and install a locking shut-off lever (see Figure 4) near the machine as a way to quickly disconnect the power and prevent accidental starting. We DO NOT recommend using an extension cord with this machine Your Shop Circuit Capacity
Always check to see if the wires in your circuit are capable of handling the amperage draw from your machine, as well as any other machines that could be operating on the same circuit. If you are unsure, consult a qualified electrician.

Phase Converter
When using a phase converter, the power from the manufactured power leg (sometimes called the wild wire) can fluxuate. Connect the manufactured power leg to the Sterminal to prevent damage to the transformer. The wire from the Sterminal can handle  Come fluxuation because it goes directly to the motor. The power going to the R and T terminals goes to the transformer and must be consistent to prevent damage.

Grounding
In the event of an electrical short, grounding reduces the risk of electric shock by providing a path of least resistance to disperse electric current. This machine must be equipped with an electric cord that has an equipment grounding conductor. This conductor must be grounded in accordance with all local codes and ordinances.
Improper connections of the electrical-grounding conductor increases the risk of electric shock. Check with a qualified electrician or one of our service personnel if you do not understand the grounding instructions, or if you doubt the machine is properly grounded.

Warning
Electrocution or fire could result if this machine is not grounded correctly or if your electrical configuration does not comply with local and state codes. Ensure compliance by checking with a qualified electrician! Extension Cords
Because of the high amperage draw from this machine, we do not recommend the use of extension cords. Instead, position your equipment near installed wiring to eliminate the need for extension cords.

Blade Tension
The only way to accurately tension the blade on this machine is with a blade tensioner such as the Model H5408 on page 33. This method is for rough blade tensioning only.
Tools Needed Qty
Hex Wrench 4mm ……………………………………… 1
Wrench/Socket 17mm ………………………………… 2

To adjust the tension:

1. Disconnect the resaw from power!

2. Remove the upper plate shown in Figure 25.

3. Loosen the vertical adjustment bolts shown in Figure 26 and lower the guide block.

4. Hand tighten the handle until the set plate contacts the sleeve shown in Figure 27.

5. Turn the bandsaw ON.
   —­If the blade flutters, increase the tension until the fluttering stops, then increase the tension an additional quarter turn.
   —If the blade does not flutter, decrease the tension until it begins to flutter, then re-tension until it stops fluttering, then increase the tension an additional quarter turn.

6. Turn the resaw OFF and disconnect the resaw from the power source!

7. Replace the blade guide upper plate and set the guides as explained in Adjusting the Blade Guides on page 42.

If the blade does not cut properly, the tension may be incorrect. Re-adjust the tension. A tension that worked well on a new blade may not work on an old blade because blades stretch with use.
Bandsaw blades will last longer and stretch less if they are de-tensioned after each use.
NOTICE
These instruction are for rough tensioning only. The only way to accurately tension the blade is with a blade tensioner. Premature blade breakage is often caused by improper blade tensioning.

SECTION 4: OPERATIONS

Operation Safety
Warning
Eyes, lung, and ear damage could result from using this machine without proper protective gear. Always wear safety glasses, a respirator, and hearing protection when operating this machine. Warning
Loose hair and clothing could get caught in machinery and cause serious personal injury. Keep loose clothing and long hair away from moving machinery. NOTICE
If you have never used this type of machine or equipment before, We strongly recommend that you read books, trade magazines, or get formal training before using this machine. Regardless of the content in this section, Grizzly Industrial will not be held liable for accidents caused by lack of training or knowledge.

Stock Preparation

Always make sure that any stock you plan on cutting is clean and free of nails, staples, or embedded stones.
Keep in mind that precision cuts require a more extended preparation process than rough cuts.
To prepare the workpiece for a precision cut:

1. Surface plane the workpiece on a jointer—The concave face of the workpiece should be planed flat on a jointer.
2. Surface plane the workpiece on a thick- ness planer—The opposite face of the workpiece should be planed flat with a thickness planer.
3. Edge joint the workpiece on a jointer – The concave edge (viewed from end-to-end) of the workpiece should be edge jointed flat on a jointer. This flat edge will glide along the fence rollers during the resaw operation.

Blade Height
The blade height is the distance between the conveyor table and the bottom of the blade.

NOTICE
The resaw blade may come into contact with the conveyor belt if lowered below 1⁄4 “.

To set the blade height:

1. Disconnect the resaw from the power source!

2. Turn the blade elevation handwheel (shown in Figure 28) counterclockwise to raise the blade or clockwise to lower the blade. Use the elevation gauge to determine the height.
   Note: Six rotations of the handwheel raises the blade approximately 1/4 “.

3. Connect the resaw to power and cut a test piece.

4. Measure the test piece to ensure the thickness matches the elevation gauge reading.
   —If the wood thickness is different than indicated on the elevation gauge, turn to Blade Elevation Gauge on page 43 for adjustment instructions.

Conveyor Controls
The Model G0503 features a variable speed infeed conveyor to move lumber through the blade. Slow the conveyor speed to get a smooth cut on hard wood, and speed it up for softer woods.

To operate the infeed conveyor:

1. Push the PUMP START button on the control panel.
2. Push the conveyor ON/OFF lever (Figure 29) forward (toward the conveyor belt) to start the conveyor.
3. Turn the conveyor speed dial (Figure 29) counter-clockwise to increase the speed or clockwise to decrease the speed.
4. Pull the engagement lever back (away from the conveyor) to stop conveyor.

Pressure Rollers
The pressure rollers hold the workpiece against the conveyor table for a smooth cut.
Tools Needed Qty
Hex Wrench 5mm ……………………………………… 1
Wrench/Socket 17mm ………………………………… 2
Wrench 35mm …………………………………………… 1

To adjust the pressure rollers:

1. Disconnect the resaw from power!

2. Loosen the jam nuts and hex bolts that secure the extension arm of the infeed pressure roller (see Figure 30).

3. Extend the pressure roller close to the blade and tighten the jam nuts and hex bolts. Make sure the extension arm can rotate without hitting the pressure roller on the blade.
   NOTICE
   The blade can move into the infeed pressure roller when the blade height is changed.
   Prevent damage by checking the pressure rollers each time the blade is adjusted.

4. Loosen the horizontal adjustment bolt indicated in Figure 31, center the pressure rollers on the workpiece, then retighten the bolt and jam nut.

5. Rotate the height adjustment nut to raise or lower the infeed pressure roller.
   —Adjust the pressure roller to apply pressure to the top of the workpiece, but not touch the table after the workpiece passes.
   —When working with thick workpieces, adjust the pressure roller so the workpiece does not hit the extension arm before con- tacting the pressure rollers.

6. If the workpiece hangs up on the outfeed pressure roller, loosen the set screws shown in Figure 32, and slide the weight up the shaft, then tighten the set screws.

Resawing
CAUTION
DO NOT cut slices thinner than 1⁄4 ” off of the bottom of the stock. Attempting to cut thin slices off of the bottom may cause the blade to cut into the conveyor belt.
To perform a resawing operation:

1. Make sure the blade is installed and tensioned correctly as described in Installing the Blade on page 22.

2. Set the blade to the desired height.
   —To cut off of the top of the stock; place the stock on the conveyor and align the top of the blade level with the top of the stock.
   Remove the stock from the conveyor and lower the blade the desired amount.
   —To cut off of the bottom of the stock; rotate the handwheel until the blade elevation gauge reads the desired height. Note—Six rotations of the handwheel raises the blade approximately 1/4 “.

3. Turn the POWER ON switch clockwise to supply power and press the MOTOR START button to start the bandsaw blade.

4. Push the PUMP START button and move the conveyor ON/OFF lever forward to start the conveyor belt (see Figure 33).

5. Adjust the conveyor speed with the variable speed adjustor shown in Figure 33. If the blade continually rotates the support bearing, reduce the speed of the conveyor.
   NOTICE
   Running the conveyor too fast can push the blade into the support bearing, grooving the bearing and causing blade breakage.

6. Make sure the workpiece is clean and free of nails, staples, or embedded stones, and has two sides that are relatively flat and parallel with each other.

7. Begin feeding the workpiece under the front pressure rollers with a flat edge against the guide rollers, as shown in Figure 34

8. Receive the workpiece on the outfeed side of the machine. Note—If a second person is receiving the workpieces, use the return rollers to send them back to the person on the infeed side.
   NOTICE
   Always de-tension blade after use. Bandsaw blades will last longer and stretch less if detensioned after each use.

Blade Information
The Model G0503 is a specialized machine that requires specialized blades. Grizzly Industrial has selected a series of blades for optimum performance on this machine. The only variables when selecting a blade are the type of cutting tooth and the number of teeth-per-inch (Tooth Pitch).
Blade Tooth Type
Carbon Steel—The less expensive carbon steel blades are adequate for most cutting applications; however, they dull quickly and for economical reasons they are usually replaced rather than resharpened.
Carbide Tipped—The more expensive carbidetipped blades are designed for continuous use in production shop situations. They hold an edge longer than carbon steel and they can be resharpened many times before needing to be replaced.
Tooth Pitch
Tooth pitch refers to the number of teeth-perinch. The more teeth-per-inch, the smoother the resulting cut, but the feed rate must be relatively slow. The less teeth-per-inch, the rougher the resulting cut, but the feed rate can be set faster.
Some trial and error may be necessary to find the right combination of cut quality, tooth pitch and feed rate.
Blade Length
The required blade length for the Model G0503 is 168″. Blade Width
The required blade width for the Model G0503 is 1″.
Blade Care
The resaw blade is a precision ground piece of steel, subject to tremendous strain. Increase the life and performance of your blade by using the correct feed rate and tension.
A clean blade will perform much better than a dirty blade. A dirty blade passes through the cutting material with much more resistance than a clean blade. This extra resistance will also cause unnecessary heat. Maintain your blades with a cleaner like OxiSolv® and a cutting blade lubricant like Boeshield® T-9 shown on page 32.
A cool blade will last longer than a blade that is overheated. The best way to keep the blade cool is with a coolant dispenser like the Grizzly model H4959 shown on page 33.
Blade Breakage
Blade breakage is unavoidable in some cases, since it is the natural result of the peculiar stresses placed on the blade. Blade breakage may also be due to avoidable circumstances, which is most often the result of poor care or judgement on the part of the operator when mounting the blade, tensioning, or adjusting the support guides.

The most common causes of blade breakage are:

• Incorrect blade tension.
• Feeding the workpiece too fast.
• Dull teeth or insufficient set.
• Not releasing blade tension after use.
• Faulty adjustment of the blade guides.
• Using a blade with an improperly finished braze or weld.
• Running the bandsaw excessively when not resawing.

SECTION 6: MAINTENANCE

| Warning
Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury.
---|---

Cleaning
Inside Wheel Cover
To keep the bandsaw working properly, regularly open the wheel cover and vacuum any sawdust from the machine that did not make it into the dust collector.
Resaw Wheels and Scrapers
Use a dry rag to wipe sawdust from the wheel scrapers. Remove sawdust build up on the wheels by rotating the wheels by hand while holding the dry rag on the contact surface.
Conveyor Belt
Use compressed air to clean the built-up sawdust from the conveyor belt. Eye injuries frequently occur when cleaning with compressed air—wear safety glasses to protect yourself! Also wear a dust mask or respirator to protect your lungs from airborne dust particles.
Painted Surfaces
These areas may be cleaned with a dry or damp rag; however, make sure you DO NOT clean bare metal surfaces with a damp rag or they may rust.
Miscellaneous

Always be aware of the condition of your machine.
Routinely check the condition of the following items and repair or replace as necessary:

• Loose mounting bolts
• Worn switch
• Worn or damaged blade
• Worn or damaged support bearings

V-Belts
To ensure optimum power transmission from the motor to the blade and to the hydraulic pump, the V-belts must be in good condition (free from cracks, fraying and wear) and operate under proper tension. Check the V-belts at least every three months; more often if the bandsaw is used daily.
See Adjusting V-Belt Tension on page 48 for instructions on properly tensioning the belts or for replacing the belts, if needed.

Bearings
Except for the bearings that are fitted with grease fittings, the bearings are sealed and pre-lubricated and require no lubrication during their usable life. All bearings are standard sizes, and replacements can be purchased from our parts department or a bearing supply store.

Greasing
Tools Needed Qty
Grease Gun……………………………………………….. 1
Hardware Needed Qty
High Temp Bearing Grease………………….. Varies
Multi-Purpose Grease………………………….. Varies
Wipe grease fittings clean and lubricate with two pumps of high-temp bearing grease. To lubricate a greased surface; wipe the surface clean and apply a thin coating of multi-purpose grease.
The photos in Figure 47 label the grease fittings and greased surfaces by number for easy identification. Match the numbers in Figure 47 to the chart below for proper greasing intervals.
Note—This page was designed to be copied and used as a check-off chart to help maintain a regular lubrication schedule. Check white boxes after lubricating fittings. Date Started:
Note — 160 hours is the equivalent of 1 month of regular use.

Hydraulic Fluid Schedule
In order for the hydraulic system to operate the conveyor properly and at the correct temperature, the hydraulic fluid level in the tank should be 2⁄3 full between the fill lines on the fluid sight window, which is located on the front of the tank (see Figure 48).

Check the hydraulic fluid level daily.
To add hydraulic fluid, wipe the dust and dirt from the breather cap shown in Figure 48 and remove the cap. Fill the tank to the full line with an ISO VG 46 hydraulic fluid. If this machine is used in extreme cold conditions use ISO VG 32 hydraulic fluid; use ISO VG 68 hydraulic fluid for extreme hot environments.Inspect and clean the breather cap and filler screen every 40 hours of regular use.
Visually inspect both the breather cap and the plastic screen that sits in the tank opening. If there is visual contamination, clean both items with solvent and compressed air. Allow them to completely dry before installing back in the tank.
DO NOT pour hydraulic fluid from the center of the screen back into the tank.

Hydraulic System Minor Service
The hydraulic system minor service consists of changing the filter, cleaning the breather cap and filler screen, and inspecting the hydraulic fluid for signs of thermal breakdown, dust contamination, and water contamination.
Perform a “Minor Service” every 960 hours, or when the filter pressure gauge (see Figure 48) nears the red.
Warning
The hydraulic system on this machine creates very high pressure and the hydraulic fluid gets hot. Always stop the resaw, make sure the pressure gauge reads 0 PSI, and make sure the fluid cools down before servicing the hydraulic system.

To inspect the hydraulic fluid:

1. Look at the color of the hydraulic fluid in the sight window.
   —­ If the fluid is milky in appearance, then the hydraulic fluid is contaminated with water.
   — If the fluid is dark brown or opaque, then the hydraulic fluid is severely contaminated or thermal breakdown has occurred.

2. Smell the hydraulic fluid (remove breather cap).
   — If the fluid smells rancid or burnt, then the hydraulic fluid has overheated and thermal breakdown has most likely occurred.
   Correct the component that is causing thermal breakdown (See Troubleshooting on page 68).

3. Determine what service is needed.
   — If the fluid is transparent and does not smell burnt or rancid, perform a minor service.
   — If the fluid is opaque, smells rancid or burnt, fix the source of contamination or the component causing thermal breakdown, then perform a major service.

To change the filter:

1. Read and understand the hydraulic safety instructions on page 11 before continuing!
2. Disconnect the resaw from the power source!
3. Thoroughly clean the area around the filter to prevent contamination of the hydraulic fluid.
4. Remove the filter shown in Figure 49. Replacement filter kits can be ordered from Grizzly Industrial using part number P0503B74.
5. Dry the filter base to remove any excess hydraulic fluid.
6. Rub clean grease on the filter gasket and screw the new filter into the filter base.
7. Tighten the filter by hand until the gasket contacts the base—then tighten another full turn.
8. Plug in the resaw and start the conveyor belt.
9. Inspect the hydraulic system for leaks.

Hydraulic System Major Service
A major service consists of performing a “Minor Service,” plus draining the fluid, cleaning the tank and screen, and filling the tank with new fluid.
Warning
The hydraulic fluid is hot and under high pressure when the hydraulic pump motor is running. Always stop the resaw, make sure the pressure gauge reads 0 PSI, and make sure the fluid is cool before servicing.

2. Remove the access plate bolts shown in Figure 51.
3. Carefully lift the access plate, pivoting around the hinge fitting in the tubing.
4. Inspect the access plate gasket for leakage. Replace with part P0503B76-1 if worn.
5. Remove the tank screen from inside the tank, clean it with solvent and compressed air, and allow it to dry.
6. Use a lint free rag to wipe up and remove any sludge from the bottom of the tank.
7. Use clean hydraulic fluid on a clean rag to wipe up additional contaminants from the bottom and sides of the tank.
8. Re-install the tank screen, replace the access plate and gasket on top of the tank, and install the drain plug.
9. Fill the tank with ISO VG 46 hydraulic fluid until the sight window is 2⁄3 full between the hi and low marks on the sight window. Note— This will take approximately 14 gallons.

Wheel Scrapers

The wheel scrapers ride directly on the wheels removing dust and shavings. The constant motion of the wheels cause the scrapers to wear down. Eventually they will need to be replaced.
Tools Needed Qty
Wrench/Socket 13mm…………………………………. 1
To replace the scrapers:

1. Disconnect the resaw from the power source!
2. Inspect the scraper to determine if it needs replaced. If the scraper is nearly parallel with the wheel, it should be replaced.

3. Turn the wheels by hand. If the bottom of the blade gullets do not remain approximately 1 ⁄16 ” away from the front edge of the wheels, then adjust the tracking.

4. Place two flat bars under the conveyer belt and place a square against the fixed wheel as shown in Figure 53. Make note of the angle between the wheel and the square.

5. Move the bars to the other side of the conveyor belt and check the adjustable wheel.
   — ­If the wheels have the same angle compared to the conveyor table, go to step 8.
   —If the wheels have different angles, proceed to step 6.

6.  Loosen the lock bolts and the jam nuts on the vertical adjusting bolts at the top of the adjusting plate shown in Figure 54.

7. Tilting Forward—To move the top of the wheel forward, loosen the lock bolt and tighten the neighboring adjustment bolt. Always loosen the jam nuts before moving the adjustment bolts, and always tighten the jam nuts after moving the adjustment bolts.
   Tilting Backward—To move the top of the wheel backward, loosen the adjustment bolt, then tighten the neighboring lock bolt.

8. Place the straightedge across the wheels, as shown in Figure 54, and examine how the wheels line up with each other.
   —­If the straightedge lies flat across the sur- face of both wheels as shown in Figure 55, skip to step 11.
   —If the wheels are not aligned, determine which direction they need to move in order to be correct, then proceed to step 9.

9. Loosen the jam nuts on the tracking adjusting bolts and loosen the lock bolts. (See Figure 56)

10. Adjust the wheels until the wheel position is correct when checked with the straightedge.

11. Spin the wheels by hand to check tracking.

12. Fine tune the adjustment bolts until the blade tracks correctly.

13. Adjust the guide bearings, close the wheel cover, and connect the machine to the power source to prepare the saw for a test run.

14. Test run the resaw and repeat this entire section if the blade does not track correctly.

Adjusting the Blade Guides
Each blade guide assembly consists of a guide block and a support wheel.
Each metal guide block has a guide slot that stabilizes the up/down movement of the blade and a support wheel to control backward movement.
The guide block alignment should be checked each time a blade is installed.

| Warning
These instructions present a serious injury hazard if done while the machine is connected to power. DO
NOT connect to power until instructed!

Wrench/Socket 19mm ………………………………… 1

To align the guide blocks:

1. Rotate the wheels by hand and watch how the blade feeds through the blade guides.
   —­If the blade feeds through the blade guide without touching the guide block or rotating the support wheel, no adjustment is necessary.
   —If the blade rotates the support wheel but does not touch the guide blocks, go to Adjusting the Support Wheel on page 43.
   —If the blade rubs against the guide blocks, continue to the next step.

2. Loosen the vertical adjustment bolts shown  in Figure 57 if the blade is not centered vertically in the guide slot.

3. Shift the blade guide adjusting bracket until the blade is centered in the guide slot.

4. Tighten the vertical adjustment bolts and repeat step 1.

5. Loosen the lower two vertical adjustment bolts if the blade guide is tilted so the blade touches the front or back.

6. Loosen the lock nut on the tilt adjustment bolt indicated in Figure 57, and adjust the tilt adjustment bolt until the guide block is level.

7. Tighten the lock nut and the vertical adjust- ment bolts, and repeat step 1.

8. Loosen the rotation adjustment bolts shown in Figure 57 if the blade touches the guide on the right or left sides.

9. Rotate the guide block until it is level and tighten the rotation adjustment bolts.

10. Test the alignment as described in step 1.
    Continue to make adjustments until the guide block no longer touches the blade.

11. Repeat the previous steps for the other guide block.

Adjusting the Support Wheel

The support wheel is positioned behind the blade to brace it from pushing backwards during a cut.
Check the support wheel spacing each time a new blade is installed.
Tools Needed Qty
Wrench/Socket 17mm ………………………………… 1
To adjust the support wheel:

1. Loosen the lock bolt shown in Figure 58.
2. Rotate the adjustment shaft until the support wheel is approximately 0.016″ behind the back of the blade. Check with a feeler gauge or four thicknesses of a dollar bill.
3. Tighten the lock bolt.
4. Spin the wheels clockwise by hand. If the support wheels turn, increase the spacing between the blade and the bearing (the bearings should only turn when cutting).
   Note—To prevent the blade from wearing a groove into the support wheel adjust the height periodically. Move the adjustment shaft up or down until the blade contacts the support wheel in a new place.

Blade Elevation Gauge
Tools Needed Qty
Wrench/Socket 17mm…………………………………. 1
Calipers…………………………………………………….. 1

To adjust the blade elevation gauge:

1. Adjust the blade height until the blade elevation gauge reads 1⁄2 “.
2. Run a test piece through the resaw and measure the thickness of the test piece with calipers.
3. Disconnect the resaw from power!
4. Loosen the bolt holding the blade elevation pointer and adjust the pointer until it is set at the same thickness as the test piece.
5. Tighten the blade elevation pointer bolt and run another test piece through the resaw to confirm the elevation pointer setting.

Adjusting Main Conveyor Table
The conveyor table can be adjusted left-to-right and front-to-back to make the table parallel to the blade in both directions. This is an involved procedure that requires you to cut up a piece of test stock and make many repeat adjustments.
Because of the complexity of this procedure, we will first give instructions on checking the table, so that you can be sure you need to perform the adjustment.
Before attempting these procedures, you need to have a perfectly squared piece of stock that is as wide as possible and is at least two feet long. The wider the stock, the more accurate your procedure will be (we recommend using the maximum width that the resaw will allow). Also, you need to make sure that your blade is in good condition, tracked, and tensioned properly, and the blade guides are properly adjusted.

Pencil……………………………………………………….. 1
Flat Piece of Wood or Metal………………………… 2
Framing Square…………………………………………. 1
Wrench 17mm……………………………………………. 1
Hex Wrench 6mm………………………………………. 1
Pry Tool…………………………………………………….. 1

To check the main conveyor table alignment:

1. Cut a 1⁄4 ” slice off of your squared-up test stock.
2. Use a caliper to measure the thickness of the cut piece in even locations along the edges of the stock. As you take these measurements, write them directly on the stock, near the location where you took the measurement (see Figure 59). Note—DO NOT measure the first and last six inches of the board, because the board will only have been under one pressure roller during that part of the cut.
3. Study the written test measurements.
   —If the measurements are more than 0.030″ different from one side to the other, adjust the conveyor table.

To adjust the conveyor table left to right:

1. Disconnect the resaw from the power source!

2. Use your test board to determine which direction the conveyor table needs to be moved. For example, if the right side of the board was thicker than the left side—you will need to move either the right side of the conveyor up or move the left side of the coneyor down.

3. Loosen all six of the conveyor mounting bolts (see Figure 60).

4. To raise the left side, loosen the lock nuts on the conveyor adjustment bolts on the left side and tighten the adjustment bolts. Do the same procedure to the right side bolts to raise the right side.

5. Tighten the lock nuts on the adjustment bolts and tighten the conveyor mounting bolts.

6. Connect the resaw to the power, and repeat steps 1 and 2.
   —If the measurements are close to correct, but need fine tuning, continue to step 6.
   —If large adjustments are necessary, repeat steps 3 and 4.

7. Loosen the cap screw shown in Figure 61.

8. The adjusting nut shown in Figure 61 raises, or lowers, the non-drive side of the bandsaw blade (the side opposite the motor). Insert the pry tool into the adjusting nut.
   —Rotate the adjusting nut to the right to raise the bandsaw blade.
   —Rotate the adjusting nut to the left to lower the bandsaw blade.

9. Retighten the cap screws, connect the resaw to the power, and repeat steps 1 and 2.
   —If the measurements are close to correct, but need fine tuning, continue to step 6.
   —If large adjustments are necessary, repeat steps 3 and 4.

To adjust the conveyor table front to back:

1. Disconnect the resaw from the power source!

2. Place two flat bars of wood or metal under the conveyer belt as shown in Figure 62.

3. Place a square against the surface of the wheel and slide it up against the bars on the conveyor table.
   — If the square touches both bars, no adjustment is necessary.
   — If the square touches the front bar, but not the back bar, the front of the conveyor needs to be raised. Go to step 4.
   — If the square touches the back bar, but not the front bar, the back of the conveyor needs to be raised. Go to step 4.

4. Loosen all six of the conveyor mounting bolts.

5. To adjust the tilt, loosen the lock nuts on the conveyor adjustment bolts on the end that needs to be raised and tighten the adjustment bolts until the square touches both bars.
   Tighten the lock nuts on the adjustment bolts and tighten the conveyor mounting bolts.

Tracking Conveyor
The conveyor is tracking correctly when it remains centered between the roller brackets on each side of the conveyor. Adjusting the tracking is only necessary if the conveyor belt starts rubbing against the roller brackets.

Tools Needed Qty
Hex Wrench 8mm………………………………………. 1
Wrench 17mm……………………………………………. 1

To set the conveyor tracking:

1. Loosen the two roller bracket cap screws on the both sides of the conveyor (shown in Figure 63) about 3⁄4 of a turn.

2. Loosen the rear adjustment nuts on both sides of the conveyor.

3. Start the conveyor belt.

4. Adjust the roller bracket that the belt is hitting by turning the front adjustment nut counter- clockwise half of a turn, and watch the belt tracking. Note—The effect of the adjustment can sometimes take two minutes before the results are fully apparent.
   — If the tracking was not corrected by this adjustment, proceed to step 5. If the tracking was corrected, skip to step 6.

5. On the side that the belt tracks away from, turn the front adjustment nut clockwise half of a turn, and watch the belt tracking.
   — If the tracking was not corrected by this adjustment, repeat step 4.

6. When the conveyor belt is tracking in the center of the roller brackets, run the con- veyor for at least two minutes to ensure that it will remain tracking correctly.
   —If the tracking was not corrected by this adjustment, repeat step 4.
   —If the belt is tracking in the center of the infeed roller, but not centered on the outfeed roller, go to step 7.
   —If the belt is tracking in the center of both rollers, go to step 9.

7. Adjust the outfeed end of the conveyor by loosening the bolts on the outfeed bearing housing (similar to the bearing housing shown in Figure 63) and sliding it forward or backwards.

8. Retighten the bearing housing bolts and run the conveyor to check the tracking.
   —If the tracking was not corrected by this adjustment, repeat step 7.

9. Tighten the rear adjustment nuts against the bracket plates, then tighten the front adjustment nuts against the bracket plates to make sure that the tracking adjustment will not slowly change during normal operation.

Replacing Conveyor
To replace the conveyor belts:

1. Start the conveyor belt and stop it when the conveyor belt seam (see Figure 64) is accessible.

2. Disconnect the resaw from the power source!

3. Loosen the roller bracket by turning the roller bracket cap screws 3⁄4 of a turn (Figure 63).

4. Loosen the rear adjustment nuts away from the bracket plate.

5. Mark the front adjustment nut with a felt- tipped pen or a piece of tape, and thread the front adjustment nut all the way up, while keeping track of the number of full turns that you moved the nut.
   Note—Write the number of turns down, so you do not forget. Remembering this number is an important part of the re-assembly process.

6. Slide the roller brackets toward the body of the resaw to loosen the belt.

7. Remove the stiff cable from the center of the seam to separate the conveyor belt.

8. Remove the old conveyor belt from the con- veyor table, and install the new conveyor belt in its place.

9. Mesh the seam “teeth” together on the new belt, and insert the stiff cable into the center of the seam to lock it together.

10. Slide the roller brackets away from the body of the resaw to tighten the belt.

11. Thread the front adjustment bolts the same number of turns as in step 5.
    Note—The new belt may be tighter than the old one because it has not been broken-in. If this is the case, deduct one or two turns from your original number of turns.

12. Run the conveyor belt to check the tracking. If the belt starts tracking to one side, stop the resaw and perform the “Tracking Conveyor” instructions that are located on page 46.

V-Belt Tensioning
Adjusting the V-belts is not an exact science.
Adjusting the belts too loose will decrease the performance of the machine, but adjusting the belts too tight may cause premature wear of the components attached to the belts.
To adjust the V-belt tension:

1. Disconnect the resaw from power!
2. Press the center of each V-belt firmly. The belts should deflect between a 1⁄4 ” and a 1⁄2 ” (see Figure 65).
3. Tension the V-belt by adjusting the motor mount nuts (see Figure 66) in or out.

Replacing V-Belts
Replace all three V-belts at the same time to ensure uniform belt tension.
To replace the belts that connect the motor to the wheel pulley:

1.  Disconnect the resaw from the power source!
2. Adjust the motor mount nuts in all the way to loosen the V-belts.
3. Place supports under the wheel and remove the cap screws shown in Figure 67.
   | CAUTION
   Each wheel weighs 175 lbs. Seek assistance or use power equipment to remove wheels.
   ---|---
4. Remove the drive wheel to access the wheel pulley.
5. Remove and replace all three V-belts that connect the motor to the wheel pulley.
6. Tension the new V-belts and replace the drive wheel.

Rewiring to 440V
Converting the Model G0503 to 440V operation consists of 1) wiring the voltage transformer, 2) rewiring the main motor and the hydraulic pump motor, and 3) replacing the over-load relays with the relays included in the Model G0503 440V Conversion Kit (item #P0503909) that is sold separately.
