SAFETY RULES:

1. KEEP GUARDS IN PLACE and in working order.
2. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and ad- justing wrenches are removed from tool before turning it on.
3. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
4. DON’T USE IN DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet locations, or expose them to rain. Keep work area well lighted.
5. KEEP CHILDREN AWAY. All visitors should be kept safe distance from work area.
6. MAKE WORKSHOP CHILD PROOF with padlocks, master switches, or by removing starter keys.
7. DON’T FORCE TOOL. It will do the job better and safer at the rate for which it was designed.
8. USE RIGHT TOOL. Don’t force tool or attachment to do a job for which it was not designed.
9. USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table A (on the next page) shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage nu- mber, the heavier the cord.
10. WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Nonslip footwear is recommended. Wear protective hair covering to contain long hair.
11. ALWAYS USE SAFETY GLASSES. Also use face or dust mask if cutting operation is dusty. Eve- ryday eyeglasses only have impact resistant lenses, they are NOT safety glasses.
12. SECURE WORK. Use clamps or a vise to hold work when practical. It’s safer than using your hand and it frees both hands to operate tool.
13. DON’T OVERREACH. Keep proper footing and balance at all times.
14. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance. Fol- low instructions for lubricating and changing ac- cessories.
15. DISCONNECT TOOLS before servicing; when changing accessories, such as blades, bits, cut- ters, and the like.
16. REDUCE THE RISK OF UNINTENTIONAL STA- TING. Make sure switch is in off position before plugging in.
17. USE RECOMMENDED ACCESSORIES. Consult the owner’s manual for recommended acces- sories. The use of improper accessories may cause risk of injury to persons.
18. NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally contacted.
19. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function – check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or re- placed.
20. DIRECTION OF FEED. Feed work into a blade or cutter against the direction of rotation of the blade or cutter only.
21. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave tool until it co- mes to a complete stop.

Proposition 65 Warning
Some dust created by power sanding, sawing, grinding, drilling and other construction activities contain chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead based paint.
• Crystalline silica from bricks, cement, and other masonry products.
• Arsenic and chromium from chemically treated lumber.

Your risk of exposure varies, depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well-ventilated area and work with approved safety equipment, such as face or dust masks that are specifically designed to filter out microscopic particles.
SAFETY RULES
As with all machinery, there are certain hazards involved with the operation and use. Using it with caution will considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored, personal injury to the operator may result.
If you have any questions relative to the installation and operation, do not use the equipment until you have contacted your supplying distributor.
Read the following carefully before operating the machine.

1. Keep the working area clean and be sure adequate lighting is available.
2. Do not wear loose clothing, gloves, bracelets, necklaces, or ornaments. Wear face, eye, respiratory and body protection devices as indicated for the operation or the environment.
3. Be sure that the power is disconnected from the machine before tools are serviced or an attachment is to be fitted or removed.
4. Never leave the machine with the power on.
5. Do not use dull, gummy or cracked cutting tools.
6. Be sure that the keys and adjusting wrenches have been removed and all the nuts and bolts are secured.

Sound emission.
Notes concerning noise emission.
Given that there exists a relationship between noise level and exposure times, it is not precise enough to determine the need for supplementary precautions. The factors affecting the true level of exposure to operators are clearly the amount of time exposed, the
characteristics of the working environment, such as other sources of dust and noise – for example, adjacent machines – in other words, the level of ambient noise. It is possible that exposure level limits will vary from country to country.

RECEIVING

Note. It is probable that your machine will be delivered by a third party. Before you unpack your new machine, you will need to first inspect the packing, invoice and shipping documents supplied by the driver. Ensure that there is no visible damage to the packing or the machine. You need to do this prior to the driver leaving. All damage must be noted on the delivery documents and signed by you and the delivery driver. You must then contact the seller (Laguna Tools) as soon as practical. If damage is found after delivery, contact the seller as soon as is practical.
Note. It is probable that you will find dust/debris within your machine. This is because the machine has been tested prior to shipment from the factory and or Laguna Tools.
Laguna Tools endeavors to test machines prior to shipping to customers, as movement can take place during transportation. It must be noted that additional machine movement can take place between Laguna Tools and the end user and that some adjustments may have to be undertaken by the customer. These adjustments are covered in the various sections of this manual. Wide belt sander with box removed.

INTRODUCTION

This machine is designed to give you years of safe service. Read this owner’s manual in its entirety before assembly or use.
Parts of the wide belt sander.
The wide belt sander consists of several major parts, which are discussed in this manual. Take the time to read this section and become familiar with the machine.
Identification.
There is a plate on the side of the machine listing all the manufacturing data, including the model and serial number. Have these numbers available when ordering supplies, accessories or parts.

---|---

1. Control panel.
   The control panel controls all the electrical functions of the machine. This includes the speed of the drive belt, vertical adjustment of the bed and on/off functions.

2. Bed, vertical setting device.
   This device is used to set the height of the bed in relation to the sanding rollers.

3. Bed, manual vertical adjusting handle.
   This handle is used to manually adjust the bed vertically.

4. Bed, conveyor.
   The bed of the sander has a rubber drive belt that transports the job through the machine. The speed of the belt is adjustable.

5. EMERGENCY STOP, (aka. safety bar, bump plate, bump bar)
   The EMERGENCY STOP safety bar is used to remove power from the motors. If a job became jammed, the bump-bar can be operated by hand, leg, or hip.

6. Machine body.
   The machine body is manufactured from heavy-gauge steel.

7. Dust extraction.
   There are three dust extraction ports located on the top of the machine and are 4 inches (100mm) in diameter. Dust extraction is critical when sanding. The sander produces dust that must be removed for health reasons and also because the belt will clog and a poor surface finish will result. It is not possible to be exact when recommending what size of dust collector should be used; this will depend on the type of work and applications that the machine is used for. It is recommended that a dust collector with a minimum of 3500 cubic feet/minute is attached to the sander.

8. Conveyor belt speed control.
   The conveyor belt speed is variable between 6-30FPM. The belt speed is adjusted by the control knob, which must be adjusted while the belt is running. To decrease the speed, turn the adjuster clockwise. To increase the speed, turn the adjuster counterclockwise. Damage may occur if operated when the conveyor is not in motion.

9. Air supply.
   A clean dry air supply with a minimum pressure of 6 bar (87 psi.) must be connected to the sander. If the pressure drops below 5 bar (73 psi.), the machine will stop functioning.

10. Electrical control box.
    The electrical control box houses all the electrical control components and must never be opened while power is supplied to the machine. 11. Main Motor/Sanding
    12. Conveyor Lift Motor
    13. Sanding Belt Limiter
    14. Sanding Belt Sensor
    15. Sanding Belt Controls

11. Sanding drum motor.

12. Conveyor bed vertical adjusting motor.
    The conveyor bed vertical adjusting motor moves a chain that rotates four cogs. The cogs turn threaded shafts that lift or lower the bed.

13. Sanding belt limiter.
    There are two ceramic limiters, one on either side of the machine. If the belt touches either of the limiters, a micro switch is activated, and the machine will stop. If the sanding belt touches any of the limiters, the sanding belt will have to be adjusted prior to restarting the sander.

14. Sanding belt senso r.
    This sensor controls the action of the sanding belt oscillation. As the belt moves in and out of the sensor, a piston moves a cam that is attached to the top sanding roller. This action changes the angle of the top roller and forces the belt to move along the roller.

15. Sanding belt control knobs.
    These knobs control the actions of the sanding belt sensor and the amount of oscillation of the sanding belt.16. Spacer

Locating the wide belt sander.
Before removing your machine from the packaging, select the area where to use the machine. There are no hard-and -fast rules for its location, but below are a few guidelines:

1. There should be an area at the front and back of the machine suitable for comfortable working and to accommodate the longest length of the work pieces.
2. Adequate lighting. The better the lighting, the more accurately and safely you will be able to work.
3. Solid floor. You should select a solid, flat floor, preferably concrete or something similar.
4. Locate it close to a power source and dust collection.
5. Allow an area for the storage of blanks, finished products and tools.

UNPACKING

To unpack the sander, you will need tin snips, knife, screwdriver, hammer, and a wrench.

1. Using the tin snips, cut the banding that is securing the packing box (if fitted). WARNING: EXTREME CAUTION MUST BE USED BECAUSE THE BANDING WILL SPRING AND COULD CAUSE INJURY.
2. Dismantle the box.
3. Remove any bolts that secure the machine to the base (if fitted).
4. Remove the machine from the base with a forklift truck. The forklift must have sufficient capacity to achieve the job safely.
5. Remove the base and lower the machine to the floor.

Note. If you have any doubt about the described procedure, seek professional assistance. Do not attempt any procedure that you feel is unsafe or that you do not have the physical capability of achieving.   

ASSEMBLY & SETUP

Very little assembly and setup is required, as the machine comes fully assembled. You will have to install the sanding belt and connect the air, dust collection and electrical supply as described in this manual.

Cleaning the machine.

Remove the rust protection packing-grease with WD-40®, green or citrus de- greasers or a similar grease-remover. It is important that you remove all the packing-grease. It is important not to introduce solvent into bearings or conveyor belt!
COMPONENTS, electrical box

ELECTRICAL SUPPLY CONNECTIONS

Note. A qualified electrician must carry out the electrical installation.
Confirm the main power supply corresponds with that of the machine motor plate and wiring, (typically three-phase, 208-240 V, 60 HZ).
It is recommended that you use a minimum 60-amp main breaker/service for 3 phase, 220-volt operation.
Due to the amp draw of this machine, it is recommended that the machine is wired directly into the electrical distribution system and is on a dedicated circuit. Do not use an extension cord.
IMPORTANT!
The correct rotation of the contact roll (sanding drum) is clockwise, when facing into the sander from the access door for belt changing. The sanding belt should rotate toward the dust collection pick-up with the sanding head making a “climb-cut” on stock being sanded. If the contact roll rotates incorrectly, with a three phase system, have an electrician reverse two of the three power leads into the input power junction block.
Connecting air supply.![LAGUNA MSANWB37X75-1K-20-0197-1 Wide Belt Sander

• fig 10](https://manuals.plus/wp-content/uploads/2023/08/LAGUNA- MSANWB37X75-1K-20-0197-1-Wide-Belt-Sander-fig-10.jpg) The input air regulator regulates the air pressure that is supplied to the machine. The machine is supplied with an air connector, to connect the air supply. An air supply that can deliver a constant minimum pressure of 6 bar (87 psi.) is required. The machine is supplied with an input air regulator that you will need to adjust to 6 bar (87 psi.) once you have connected your air supply to the machine.
  Note. No air pipe is supplied, as the length will depend on your installation.
  To adjust the air pressure, pull the cap up and rotate until the gauge reads the correct pressure. Once the pressure is adjusted, push the cap in.
  Note. An air supply of 6 bar (87 psi.) minimum is required for the machine. It is strongly recommended that 7 bar (102 psi.) be supplied to the machine and that the regulator then be set to 6 bar (87 psi.). This will ensure that the machine always has the  inimum required air pressure.
  The input regulator has a moisture trap that must be emptied each day.
  Note. It is important that the air that is supplied to the machine be clean and dry. The machine will not perform consistently if the air is dirty, as any dirt will block the valves. Wet or damp air will damage your machine and cause inconsistent performance.
  Note. The pneumatic system does not need any type of lubricant. Some types of lubricant can damage the machine and compromise the machine’s functions.
  Note. During maintenance, always disconnect the air supply.

INSTALLING ABRASIVE BELT

Note. Disconnect the sander from the electrical supply. 

1. Disconnect power to machine. Rotate the roller tension switch counterclockwise to lower the tension roller.

2. Rotate the clamp counterclockwise and lift it out.
   Note. The clamp is a quick-release and needs only to be rotated approximately 90 degrees to release.

3. Remove the spacer. This will allow access for the sanding belt.

4. Slide the sanding belt onto the top and bottom rollers.
   Note. Ensure that the direction arrows on the inside of the sanding belt are facing in the correct direction (clockwise). If the belt is assembled with the arrows in the incorrect direction, the belt will not track properly and/or break.

5. Replace the spacer and clamp.

6. Rotate the roller tension switch clockwise to raise tension roller.

Note. Never run the sander without the spacer and clamp assembled, this will damage the machine.
Note. The machine is supplied with a sanding belt and may not be the correct one for your work/application. Purchase several sanding belts to suit your applications and always have spare belts available; you can never predict when a belt will break or wear out.
Note. The sanding belt must be positioned centrally on the rollers. It must also be between the forks of the belt sensors.
Choosing abrasive belts.
The grit type (backing and material) that you choose will depend on the type of work and the finish that the job dictates. It usually saves time and results in a better finish if you start a job with a coarse grit and then complete the finishing cuts with a fine grit. This will entail changing the sanding belts but can save time in the long run.

NOTE: Modern abrasive materials (e.g. ceramics, zirconium, etc.) and backings can be a better, more economical choice for many applications. Consult your abrasive supplier for details.

Starting the sander.

1. Connect the sander to the power.

2. Press the table up and down keys. The table should move smoothly and the display figures change.
   Note. Check that the table moves in the correct direction according to the arrow that is being pressed. If the table moves in the incorrect direction, changing two of the phases (wires) of the input cable (3 phase machines only) should correct the issue.

3. Press the conveyor start and stop buttons. The conveyor should start, run and stop smoothly.

4. Press the sanding belt start and stop buttons. The sanding belt should start, run, and stop smoothly.

5. Let the sander run for a few minutes and listen for unusual noises or vibration. If any unusual noises or excessive vibration is detected, correct the problem before sanding a job.

Adjusting the sander.
There are two main functions to adjust on the sander: the bed of the sander and the sanding belt.
Vertical adjustment of the bed.
The bed can be adjusted either manually or electronically.
Manual vertical bed adjustment.  The manual handwheel is located on the front of the machine under the bed. It is not recommended that the wheel is used for everyday operations and is only used for fine tuning and setting, emergency operations, or when the bed must be moved while no power is connected to the machine.
Electronic vertical bed adjustment/Control Panel.

Control panel
The control panel is set on the front of the machine. It has a control pad and  several buttons. The numeric pad controls the vertical movement of the bed.

1. Numeric pad for inputting dimensions into the computer.
2. Bed up button.
3. Bed down button.
4. Set button.
5. Bed start button.
6. Bed stop button.

Calibrating the control panel.
Sand a piece of wood and measure the thickness. The sander must have been adjusted prior to sanding the wood. See sanding belt adjustment.
Using the numeric pad, input the thickness of the wood.
Press the set button and hold for 2.5 seconds.
The computer is now calibrated.
NOTE: Calibrating the control panel is the only time wood should be sanded using a metal sanding wide belt sander.
Setting the depth of cut (sanding depth).

• Press any button, and the display will read 000.0″.
• Input the depth of cut using the numeric keypad (0,005″).
• Press the set button and hold for 2.5 seconds. The display will begin to flash; when it stops, the depth of cut is set.
• Press the start button, and the display will revert to 000.0″. The input and run lights will illuminate, and the table will move to the new dimension.

A second method of setting the depth of cut is to press the arrow UP button until the desired depth of cut is reached.
Note. If you go past the dimension, press the arrow DOWN button to lower the table.
Note. The magnification resolution can be changed by changing the position of a switch that is located on the back of the control panel. This is not recommended, as the machine has been set to suit most workshop usages.
Automatic Thickness Control/Quick set Micro Switch.
The sander has a device on the side that is used to set the height of the bed without measuring the job. Simply put the job on the height setting button, press and hold the arrow up button. The table will move up until the job hits the micro switch. The distance between the sanding head and the job is now set. Set the depth of cut as described earlier. Micro switch & Height setting button

HINT, Setting Depth of Cut.
If you are not certain setting the depth of cut; Measure the thickness of the stock. Place the stock on the conveyor under the sanding head (with abrasives installed). Raise the conveyor bed by hand using the handwheeluntil the stock is touching the abrasive belt and the belt can be rotated using hand pressure. Note the height setting on the DRO, lower the conveyor bed, remove the stock. Reset the thickness to the DRO setting. Start machine and process stock.
Setting the display to metric or inches.
Press the set button for 10 seconds, and the display will change from inches to metric, or vice versa.
Down limit switch. The sander is fitted with a limit switch located at the back of the machine.
This limit switch limits the down travel of the bed.
CONVEYOR BELT SPEED

The speed of the belt can be adjusted to between 6 and 30 feet per minute.
The speed is infinitely variable to suit the various applications to be sanded. It is a matter of experience when selecting the correct speed.
Change the speed by rotating the belt speed adjuster while the motor is running. Clockwise decreases the speed, while counterclockwise increases the speed.
Note. Never adjust the speed while the conveyor motor is not running, as this will cause damage to the machine.
Belt drive gear box.
The belt drive gear box is filled with oil. As the oil heats, it expands and causes pressure within the gear box. To relieve this pressure, there is a small hole on the side of the red bolt. To ensure there is no leakage during shipping, the hole is sealed with a small  plastic pin. Before the machine is run, this pin must be removed. This will allow the oil to expand without causing damage or leakage during use.

SANDING BELT ADJUSTMENTS

General description of sanding controls and actions. The sanding belt is tensioned by the central belt tension piston. The piston is activated by the sanding belt tension switch. This switch must be activated prior to starting the sander. The sanding belt oscillates along the top and bottom rollers. This greatly enhances the performance of the sander and reduces the chances of lines and marks on the job. To achieve this oscillation, the top roller pivots about a central air cylinder (1). This air cylinder also keeps pressure on the belt and keeps it tight to the rollers. The pivoting is controlled by a non-contact air sensor (4). Should the sanding belt break, a micro switch (3) is activated and stops the machine. If the oscillation is excessive or the sanding belt runs off center, the sanding belt will hit one of the two ceramic rollers (2). The rollers are attached to micro switches that stop the machine. The sensitivity of the non-contact air sensor can be adjusted by rotating the control knob (5]) This has been factory set and should not need adjustment. The speed of the belt oscillation can be
increased or decreased by adjusting the control knob (6).
The sanding belt is centralized on the rollers by adjusting the sanding belt centralizing cam. This will have to be done for every belt, as each belt will run differently.

2. The top roller should pivot, and when the obstruction is removed, the top roller should pivot back to the original position.

3. Check that the roller pivots a few times.

4. With the sanding belt installed, run the sanding head and note the time that it takes the sanding belt to oscillate in both directions. The time taken to oscillate in either direction should be the same.

5. If the oscillation to the right is longer than the time for the sanding belt to oscillate to the left, adjust the control knob (5) to the right.

6. The speed of oscillation is adjusted with control knob (6). The speed of oscillation will change the sanding results. Test the sanding results with a piece of scrap.

7. Turning the knob clockwise will reduce the oscillation speed.

Running the machine after installing a new sanding belt.

1. Fit the sanding belt as detailed earlier.
2. Check that the belt is not hitting the ceramic rollers and is positioned approximately central on the rollers.
3. Check that the emergency stop button is not engaged (twist to release).
4. Check that the bed is at least 1 inch down from the sanding belt.
5. Check that the sanding belt tension piston has been activated.
6. Press the sanding belt start button. The sanding belt will start to rotate.
7. Open the left-hand door and check that the sanding belt oscillations are central on the rollers. You will probably find that they are biased to one end.
8. Press the sanding belt stop button. After the belt has completely stopped, loosen the sanding belt centralizing cam and move either left or right depending on the error.
9. You may find that the sanding belt will have hit one of the ceramic rollers. This will mean that the sanding belt is not running central. Release the sanding belt tension piston and re-centralize the belt on the rollers. Then adjust the sanding belt centralizing cam and retest.

Note. As the name implies, this is a sanding machine and is not designed to cut large amounts of material from the job. It is far better to take several small slow cuts rather than one large cut. The sanding belt will last far longer, the surface finish will be better, and the machine will not be damaged.
Testing the machine.
Note. Remove all tools and other materials from the machine prior to testing it.

1. Connect the electrical supply.
2. Switch “ON” the sanding machine momentarily. Check that the sanding belt is running true and balanced on the rollers.
3. If the belt is not running true, adjust the belt (detailed later in the manual).
4. If the belt is running true and balanced on the rollers, switch on the machine and allow the machine to run for a few minutes.
5. While the machine is running, check for rattles and vibration. If rattles or vibration is detected, investigate the cause and tighten/correct the relevant parts.

Check that all the safety switches are functioning.

1. Lower the bed until it hits the lower limit switch. The bed travel must stop once the switch is activated.
2. With the sanding belt and the drive belt running, activate the bed safety switch. The sanding belt and the drive belt must stop once the safety switch has been activated.
3. Raise the bed until it hits the bed upper limit switch. The bed travel must stop once the switch is activated.
4. With the sanding belt and the drive belt running, press the emergency stop button.
5. With the sanding belt running, press the sanding belt stop button.
6. With the drive belt running, press the drive belt stop button.
   

Operating/Sanding.
Sanding is a finishing process, and no more than 0.008″ should be removed with each pass. Larger cuts will result in jamming, poor surface finish, burn marks, excessive sandpaper wear, excessive motor loading, and so on.
Wearing the correct safety equipment, start sanding as follows.

1. Switch on the dust collector.
2. Set the bed to a height that will just miss the thickest part of the job.
3. Raise the table with each pass until the job is sanded over the complete surface.

Maintenance and troubleshooting.

Note. When conducting maintenance, disconnect the machine from the electricity and the air supply.
General.
Keep your machine clean. At the end of each day, clean the machine. If dust is not removed, it will cause rust. In general, we recommend that you only use a Teflon-based lubricant.
Regular oil attracts dust and dirt. Teflon lubricant tends to dry and has fewer tendencies to accumulate dirt and dust.
Weekly (Daily in heavy work environments).

1. Check that all nuts and bolts are tight.
2. Check the sanding belt for damage and wear.
3. Check cables for wear, damage, or cuts.
4. Empty the two water traps.
5. Remove any excessive dust and check the dust extraction system for blockages.
6. Grease the bearings.

Monthly.

1. All the above.
2. Cover the table adjustment screws with grease. Ensure that the rubber covers are replaced once greasing has been completed.
3. Grease the table lifting chain.

After the first 100 hours of operation, replace the oil in the conveyor drive gear box. Repeat the oil change every 2,500 hours. Recommended oil 90 wt. gear oil.
Drive V-belts.
The drive belts should last for a long time (depending on the usage) but need to be inspected regularly for cracks, cuts and general wear. If damage is found, replace the belts.
The belts come factory set, but they should be checked for tension after about 8 hours of use. The belts could need to be re-tensioned, as they will have bedded into the “V” grooves.
Note. The sanding head motor has multiple belts. They are matched, so if one belt requires replacement, you must replace all the belts with a matched set. If all the belts are not replaced, this will cause vibration and could put excessive strain on the motor and bearings. Not replacing all the belts will also cause the belts to wear out very quickly, as they are not all the same length and will slip.
Bearing lubrication.
The bearings need to be greased. There are several grease points, as shown in the photographs below. It is recommended that the machine be greased after every 40 hours of operation. Greasing the bearings will flush out dust from the seals. After greasing, wipe off any excess. A grease gun extender is supplied to ease access to the bearings. Sanding belt non- contact air sensor.
There are holes in the sensor for the air to escape through. The holes should be checked regularly, and if they block, they must be cleaned. If the holes block, the belt will not track correctly on the rollers.
Ceramic rollers. The ceramic rollers must be checked regularly for wear, cracks and general damage. Two spares are supplied.
Pressure roller adjustment.       There are four pressure rollers: two on the infeed side and two on the outfeed side of the contact roll. The pressure rollers come factory set but may need to be adjusted during the life of the machine or certain applications.
Adjust the rollers as follows.

1. Place a panel on the bed of the sander so that it is under both the infeed and outfeed rollers.
2. Set the bed of the sander vertically so that one of the pressure rollers just touches the panel.
3. Loosen the lock nuts and adjust the pressure rollers so that they are both just touching the panel. This must be completed at the extremities of the rollers to ensure that they are parallel.
4. With the rollers parallel, adjust the rollers to the required setting and lock the lock nuts.

Note. When adjusting the height of the pressure rollers, after ensuring that they are parallel, adjust each screw the same amount or the rollers will not be parallel.
Note. Adjusting the pressure rollers must be done with the sanding belt stationary.
Note. The amount of pressure that you set the pressure rollers to exert on the job will vary depending on such variables as the depth of cut, hardness of the material and other factors. Experimentation will be required to achieve the correct setting. It is suggested that setting the pressure rollers to 0.020″ to 0.030″ is a good starting point. Never set the pressure rollers level or higher than the sanding roller (contact roll), as this may result in injury from stock slippage.
Adjusting/tracking the conveyor belt. The conveyor belt comes factory set but may need to be adjusted at some time.
The conveyor belt must run centrally on the rollers and must be tensioned to prevent slippage. If the belt is not running centrally, check that the tension is correct before adjusting the tracking. Adjust is as follows.
Conveyor tracking adjustment.

1. You may find it easier to remove the steel cover to expose the two guide wheels. To achieve this, remove the fixing screws.
2.  Turn the conveyor on.
3. If the conveyor is running to the right, turn the right-hand adjusting screw clockwise. Only make very small adjustments and wait for the conveyor to settle before making additional adjustments. It is better to take your time and not rush the adjustments.
4. If the conveyor is running to the left, turn the left-hand adjusting screw clockwise.
5. Once the conveyor is running centrally, stop the conveyor and replace the steel cover.

Conveyor tensioning.
To increase the tension on the conveyor belt, turn the adjusting bolts clockwise. To reduce the tension on the conveyor belt, turn the adjusting bolts counterclockwise.
Note. Adjust both adjusting bolts the same amount or the tracking will be affected.
Motor drive V-belt adjustment.   Sanding head drive motor V-belt adjustment/tension.
The sanding head drive motor has a brake that is activated when the power is removed from the motor. The brake is air activated and should not need any regular servicing.
The drive V-belts will need to be adjusted from time to time. To adjust, loosen the lock nut and turn the adjusting nut (under bracket) until the correct tension is achieved. Do not forget to re-tighten the lock nut after the adjusting has been completed.
Note. Never access the motor with the power connected to the sander.
Conveyor drive motor belt adjustment.
The drive belts will need to be adjusted from time to time. To adjust, loosen the lock nut, and turn the adjusting nut (on top of bracket) until the correct tension is achieved. Do not forget to re-tighten the lock not after the adjusting has been completed.
Note. Never access the motor with the power connected to the sander.

1. Remove the access panel to expose the sanding drum motor.
2. Check the thickness of the disc pads. The pad is constructed from a metal backing plate and breaking material. The breaking material must be a minimum of 1/8″ thick. If either of the pads is thinner than 1/8″, both pads must be replaced.
3. Remove the nuts from the two mounting bolts and the two snap rings on the pins behind the bracket.
4. Pull the pins out.
5. Remove the air line and remove the caliper.
6. Disassemble the caliper and remove the disc pads.
7. Clean and degrease the disc. Check the disc for cracks and general wear. If the disc is damaged or worn excessively, have it resurfaced prior to fitting the new brake pads.
8. Assemble the new pads and reassemble the caliper to the sander. Ensure that the air is reconnected to the caliper.
9. Test the brake system by pressing the emergency stop button; the sanding drum must stop rotating quickly and smoothly.

Accessing sanding head drive motor electrical termination.

To access the motor electrical terminations, remove the cover plate located beside the air regulator.
Note. Never access the motor with the power connected to the sander.
