Know what conditions can create “kickback” and know how to avoid them. Read the manual accompanying the machine thoroughly. 18. CHECK DAMAGED PARTS. Before fur-ther 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, bind-ing 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 replaced. 19. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave tool until it comes to a complete stop. 20. NEVER OPERATE A MACHINE WHEN TIRED, OR UNDER THE INFLUENCE OF DRUGS OR ALCOHOL. Full mental alert-ness is required at all times when running a machine.

CAUTION
No list of safety guidelines can be com-plete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious personal injury, damage to equip-ment or poor work results.

WARNING

Additional Safety Instructions For Bandsaws

1. DO NOT OPERATE WITH DULL OR BADLY WORN BLADES. Dull blades require more effort to use and are difficult to control. Inspect blades before each use.
2. NEVER POSITION FINGERS OR THUMBS IN LINE WITH THE CUT. Serious personal injury could occur.
3. DO NOT OPERATE THIS BANDSAW WITHOUT WHEEL, PULLEY, AND BLADE GUARDS IN PLACE.
4. WHEN REPLACING BLADES, make sure teeth face down towards the table. The force of the cut is always down. Make sure the blade is properly tensioned.
5. CUTS SHOULD ALWAYS BE FULLY SUPPORTED by the table or some type of support fixture. Always support round stock in a V-block.
6. DO NOT BACK WORKPIECE AWAY from the blade while the saw is running. Plan your cuts so you always cut out of the wood. if you need to back the work out, turn the bandsaw off and wait for the blade to come to a complete stop. Do not twist or put excessive stress on the blade while backing work away.
7. ALWAYS FEED STOCK EVENLY AND SMOOTHLY. Do not force or twist blade while cutting, especially when sawing small radii.
8.  THIS MACHINE IS NOT DESIGNED TO CUT METAL or other material except wood.
9. BLADE SHOULD RUNNING AT FULL SPEED before beginning a cut.
10. DO NOT MANUALLY STOP OR SLOW BLADE after turning the saw off. Use foot brake.
11. ALL INSPECTIONS, ADJUSTMENTS, AND MAINTENANCE ARE TO BE DONE WITH THE POWER OFF and the plug pulled from the outlet. Wait for all moving parts to come to a complete stop.
12. Habits – good and bad – are hard to break. Develop good habits in your shop and safety will become second-nature to you.

Always wear ANSI-approved safety glasses or goggles and hearing protection when operating equipment — particularly when testing new tools or machinery. Do not allow visitors into your workshop when testing or operating equipment. Serious personal injury may occur.

CAUTION
No list of safety guidelines can be com-plete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious personal injury, damage to equip-ment or poor work results.

CIRCUIT REQUIREMENTS

220V Operation

The motor supplied with the G7211 comes prewired for 220V. Refer to the wiring diagram supplied at the back of this manual for more spe-cific information about wiring connections. The G7212 is a 220V, three-phase motor and requires special electrical service. See section on three-phase operation on the next page.
This machine does not come supplied with a plug, therefore a suitable 220V plug must be wired in. When operating at 220V, we recommend using a NEMA-style 6L-15 plug and outlet. See Figure 1. You may also “hard-wire” the machine directly to your panel, provided you place a disconnect switch near the machine. Check the electrical codes in your area for specifics on wiring require-ments.
Under normal use, the motor draws approximate-ly 20 amps @ 220V. We recommend a 25 amp circuit breaker for 220V operation. This should be satisfactory for normal use while providing enough protection against motor damage caused by power surges.

Extension Cords

We do not recommend the use of extension cords on 220V equipment. It is much better to arrange the placement of your equipment and the installed wiring to eliminate the need for extension cords. Should it be necessary to use an extension, make sure the cord is rated Hard Service (Grade S) or better. Refer to the chart in Section 1: Safety Instructions to determine the minimum gauge for the extension cord. The extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords when they become worn or damaged.

Wiring Diagram
Your G7211 machine comes pre-wired for 220 volt operation. A wiring diagram is provided at the back of this manual should it be necessary to repair or revise the wiring. Always utilize a quali-fied electrician when doing any electrical work on this equipment.

Phase Operation

The Model G7212 has a 7.5 H.P. motor config-ured to operate under three-phase electrical serv-ice. Generally this type of electrical supply is only found in commercial or industrial locations. Connection to three-phase service should only be done by a qualified electrician.
If you do not have three-phase service available a phase converter can be utilized in conjunction with a 220V single phase power supply. Refer to the Grizzly catalog for a complete range of phase converters.

CAUTION
We have covered some basic electrical requirements for the safe operation of your Bandsaw. These requirements are not nec-essarily comprehensive. You must be sure that your particular electrical configuration complies with local and state codes. Ensure compliance by checking with your local municipality or a licensed electrician.

The specifications, drawings, and photographs illustrated in this manual represent the Model G7211/G7212 as supplied when the manual was prepared. However, owing to Grizzly’s policy of continuous improvement, changes may be made at any time with no obligation on the part of Grizzly. Whenever possible, though, we send manual updates to all owners of a particular tool or machine. Should you receive one, we urge you to insert the new information with the old and keep it for reference.

WARNING
To operate this or any power tool safely and efficiently, it is essential to become as familiar with it as possible. The time you invest before you begin to use your Model G7211/G7212 will be time well spent. DO NOT operate this machine until you are completely familiar with the contents of this manual. Serious personal injury may occur.

Unpacking

The bandsaw is shipped from the factory in a carefully packed carton. If you find the machine to be damaged after you’ve signed for delivery and the truck and driver are already gone, you will need to file a freight claim with the carrier. Save the containers and all packing materials for inspection by the carrier or their agent. Without the packing materials, filing a freight claim can be difficult. If you need advice regarding this situation, please call us immediately.
When you are completely satisfied with the condi-tion of your shipment, you should inventory its parts.

WARNING
The G7211/G7212 is a very heavy machine with a shipping weight of 725 lbs. DO NOT over-exert yourself while unpacking or moving your machine – get assistance. In the event that your bandsaw must be moved up or down a flight of stairs, be sure that the stairs are capable of supporting the combined weight of people and the machine. Serious personal injury may occur.

NOTICE
Save all containers and packing materials until you are satisfied that your bandsaw has arrived in good condition. Freight company adjusters will want to inspect those materials in the event that a freight claim must be made.

Parts Inventory

Take a quick inventory of the parts and put them aside for assembly later. After all the parts have been removed from the container, you should have:

• Bandsaw Assembly
• Fence Assembly
• Miter Gauge
• Hardware
  • Cap Screws 5/16″ – 18 x 21/2″2
  • Fence Rail Spacers 2
  • Fence Rail 1

In the event that any non-proprietary parts are missing (e.g. a bolt, nut or a washer), we would be glad to replace them, or, for the sake of expediency, replacements can be obtained at your local hardware store.

Clean Up

The unpainted surfaces are coated with a waxy oil to protect it from corrosion during shipment. Remove this protective coating with a solvent cleaner or citrus-based degreaser such as Grizzly’s G7895 Degreaser. Avoid chlorine-based solvents as they may damage painted surfaces should they come in contact. Always follow the usage instructions on the product you choose for clean up.

WARNING
Many of the solvents commonly used to clean machinery can be highly flammable, and toxic when inhaled or ingested. Always work in well-ventilated areas far from potential ignition sources when dealing with solvents. Use care when disposing of waste rags and towels to be sure they do not create fire or environmental hazards. Keep children and animals safely away when cleaning and assembling this machine.

• Do not use gasoline or other petroleum-based solvents to remove this protective coating. These products generally have low flash points which makes them extremely flammable. A risk of explosion and burning exists if these products are used. Serious personal injury may occur.

CAUTION
All die-cut metal parts have a sharp edge (called “flashing”) on them after they are formed. This is generally removed at the factory. Sometimes a bit of flashing might escape inspection, and the sharp edge may cause cuts or lacerations when handled. Please examine the edges of all die-cut metal parts and file or sand the edge to remove the flashing before handling.

Site Considerations

FLOOR LOAD
Your G7211/G7212 Bandsaw represents a large weight load in a small footprint. Most commercial floors are suitable for the Model G7211/G7212. Some residential floors may require additional build up to support both machine and operator.

WORKING CLEARANCES
Working clearances can be thought of as the dis-tances between machines and obstacles that allow safe operation of every machine without lim-itation. Consider existing and anticipated machine needs, size of material to be processed through each machine, and space for auxiliary stands and/or work tables. Also consider the relative position of each machine to one another for effi-cient material handling. Be sure to allow yourself sufficient room to safely run your machines in any foreseeable operation.

LIGHTING AND OUTLETS
Lighting should be bright enough to eliminate shadow and prevent eye strain. Electrical circuits should be dedicated or large enough to handle combined motor amp loads. Outlets should be located near each machine so power or extension cords are not obstructing high-traffic areas. Be sure to observe local electrical codes for proper installation of new lighting, outlets, or circuits.

CAUTION
Make your shop “child safe”. Ensure that your workplace is inaccessible to young-sters by closing and locking all entrances when you are away. Never allow visitors in your shop when assembling, adjusting or operating equipment.

ASSEMBLY

Fence

Most of your G7211/G7212 24” Bandsaw has been assembled at the factory. Only the fence assembly requires installation.

To mount the fence to the bandsaw table:

1. Mount the front rail to the table using two (2) 5/16 – 18 x 21/2” Cap Screws and the two (2) Spacers provided. See Figure 2.
2. Loosen the fence lock knob and slide the fence onto the rail.

WARNING
DO NOT attempt any step of assembly,adjustments, or maintenance while your Model G7211/G7212 is running. Ensure that the switch is off, power is disconnected and moving parts have stopped before making adjustments. Failure to comply may result in serious personal injury.

ADJUSTMENTS

Tracking

To adjust the tracking:

1. Disconnect the bandsaw from the power source and open the top and bottom wheel covers. Adjust the upper and lower guide assemblies away from the blade.
2. Loosen the lock nut on the tracking knob. See Figure 3. Rotate the upper wheel by hand and adjust the tracking knob (turn the tracking knob clockwise to track the blade in, counterclockwise to track out) until the flat body of the blade tracks in the center of the upper wheel. Turn the wheel at least three full turns to ensure that the blade is tracking in its final position.

CAUTION
Use extreme care when turning the bandsaw wheel. The upper wheel may have sharp edges and any procedures which require work in close proximity to the bandsaw blade could result in serious injury.

Tension
Final blade tension ultimately depends on the type and size of blade you use. To adjust the ten-sion:

1. Raise the blade guard to its fully retracted position.
2. Press, with moderate pressure, on the face of the blade with your thumb.
3. Turn the tension wheel until the blade deflects about 1/4″. See Figure 4.
4. Make the other adjustments to the saw and test run it. If the blade is not cutting proper-ly, the tension may need to be increased. Remember, thin blades require less tension than wide blades.
5. Reduce the blade tension when the band-saw is not in use. This will help prevent pre-mature wear or breakage of the blade and/or rubber tires.

Wheel Alignment

For proper operation of the bandsaw it is impor-tant that the upper and lower wheels be aligned so they are in the same plane. See Figure 5 to understand the relationship between the wheels.

On the G7211/7212 it is not possible to lay a straightedge across the two wheels to check coplanarity and parallelism because of the arrangement of the wheels in the cabinet. The wheel relationship can be checked by clamping two blocks of exactly the same size (must be at least 2″ high to extend beyond the cabinet) and squareness to each wheel (use the large holes in the wheels for the clamp), then use a straightedge to check the wheel position. It will be necessary to remove the fence and the table to perform this check.

The adjustment knobs on the upper wheel (See Figure 6) can be used to correct for deviation in parallelism between the two wheels. Although this has been set at the factory, it is a good idea to check it occasionally to assure proper operation of your bandsaw. Loosen the check nuts and adjust as necessary by turning one knob in and the other knob about the same amount. Adjust in small increments and check the measurement between the wheels until the wheels are in alignment.

If the wheels are not coplanar, the bearing mount on the lower wheel can be adjusted to move the wheel position in or out, or the wheel can be shimmed on its shaft. This is a major service procedure, however, and should be undertaken very carefully. Normally the positioning of the wheels will not change as long as the saw is properly cared for and is not dropped or tipped onto its back or side. Contact Customer Service for more information on wheel alignment if you are experiencing difficulty.

Upper Guides

Normally Steps 1-4 are implemented prior to installing a new blade. Refer to Figure 7 to identify the components of the guide assembly. To adjust the upper guides:

1. Loosen the bearing guide shaft lock nuts.
2. The bearing guides are mounted on an eccentric shaft. With a regular screwdriver, rotate the guides away from the blade.
3. Loosen the cap screw holding the rear sup-port bearing in place and slide the rear support bearing away from the blade.
4. Loosen the cap screw holding the blade guide assembly in place and slide it back away from the blade.
5. Install your blade of choice. Track and ten-sion as per the instructions in this manual.
6. Move the blade guide assembly so the bearing guides are 1/16″ behind blade gullets. Tighten the guide assembly.
7. Now rotate the bearing guide shafts until the bearings are approximately 1/64” from the blade. Hold the shafts in place with a screwdriver and tighten the bearing guide lock nuts. The guide bearing, when adjusted correctly, should have a slight drag against the blade. If the guide bearings pinch the blade, it will damage the bearing guides and blade.
8. Slide the rear support bearing until it is approximately 1/32” from the blade and tighten.

NOTICE
The bearing guide shaft lock nuts should only be as loose as necessary to allow the shafts to rotate. If they are too loose it will be very difficult, if not impossible, to adjust the guides accurately.

Lower Guides

Normally Steps 1-4 are implemented prior to installing a new blade. Refer to Figure 8 to identify the components of the guide assembly.To adjust the lower guides:

1. Loosen the lower guide lock nuts and thread the shafts out so the blade guides are away from the blade.
2. Loosen the setscrew that holds the rear support bearing in place and slide it back.
3. Loosen the bolts that hold the lower guide assembly in place and slide the lower guide back.
4. Install blade. Track and tension according to the instructions in this manual. It is recommended that you adjust the upper guides first, then the lower.
5. Slide the lower guide forward so the bearing guides are 1/16″ behind blade gullets. Tighten the lower guide assembly.
6. Thread in the lower blade guide adjusters until the blade guides are approximately 1/64” from the blade. Tighten the lock nuts.
7. Slide the rear support bearing until it is approximately 1/32” from the blade and tighten.

WARNING
DO NOT make adjustments while the band-saw is running. Ensure that the switch is off, power is disconnected and moving parts have stopped before making adjustments. Failure to comply may result in serious per-sonal injury.

Positive Table Stop

To adjust the positive stop so the table will be perpendicular to the blade:

1. Loosen the trunnion lock handle and check nut locking the positive stop adjusting bolt. See Figure 9.
2. Raise the upper blade guide assembly up and stand a machinist’s square or adjustable square on the table next to the side of the blade. Adjust the positive stop adjusting bolt to raise or lower the table until the table is 90° to the blade.
3. Secure the trunnion lock handle and lock the positive stop adjusting bolt by tightening the lock nut. Ensure that the bolt does not turn while tightening the lock nut.
4. Adjust the pointer on the table so that i points directly to 0˚.

OPERATIONS

The bandsaw is one of the most versatile machines in the shop. It can cut miters, com-pound angles, simple and complex curves, circles, and a wide variety of irregular shapes. It can also rip and crosscut, as well as cut a variety of joints. The bandsaw will also resaw stock into thinner boards.

Pre-Run Check

There are many adjustment points and compen-sating differences to consider when operating this type of saw. Therefore, cutting results can be somewhat unpredictable if some or all of the cru-cial adjustments are neglected. Here are a few simple things you can do to increase the pre-dictability of your bandsaw’s performance:

1. Always use a sharp, high-quality blade. Although you might save a few dollars ini-tially, buying a cheap blade will give you cheap results. As a rule, spending more now saves you money later.
2. Use the right blade for the job. Resawing with a 1/16″ blade or doing scrollwork with a 1″ blade are extreme examples of using the wrong blade for the job.
3. Set the top guide assembly so it is just above the top of the work at all times.
4. Allow the saw to cut. Don’t force the workpiece into the blade. When cutting curves or irregular shapes, remember that while negotiating a curve, the blade should still be cutting wood. Simply turning the workpiece will only bind the blade and could break it.
5. Maintain your bandsaw in top condition. See the following section of this manual for maintenance procedures.

Bandsaw Blades

A bandsaw blade is a delicate piece of steel sub-jected to tremendous strain. Be sure you use quality blades of the proper width for the various types of cutting operations. The Grizzly G7211/7212 24″ Bandsaw accepts 1541⁄2″ blades ranging in widths from 1⁄2″ to 11⁄4″.
Always use the widest blade possible for the workpiece you are cutting. Use narrow blades only for sawing small, abrupt curves and for fine, delicate work. Bandsaw blades can be purchased welded, set, and sharpened ready-for-use from Grizzly’s catalog or website.
Always select and use good-quality saw blades and choose the right blade for the job. Poor qual-ity blades and improper use are often the cause of premature blade failure.
Many conditions can lead to breakage. Blade breakage is, in some cases, unavoidable, since it is the natural result of the peculiar stresses that bandsaw blades are subjected to. Blade break-age is also due to avoidable causes. Avoidable breakage is most often the result of poor care or judgement on the part of the operator when mounting or adjusting the blade or support guides. The most common causes of blade break-age are: (1) faulty alignment and adjustment of the guides; (2) forcing or twisting a wide blade around a curve or short radius; (3) feeding too fast; (4) tooth dullness or absence of sufficient set; (5) excessive tension; (6) upper blade guide assembly set too high above the workpiece; (7) using a blade with a lumpy or improperly finished weld; and (8), continuously running the bandsaw when not in use.

Changing Blades

To remove the blade, ensure the power is discon-nected and:

1. Loosen tension on the blade by turning the tension control knob.
2. Remove the table insert and table pin.
3. Remove the fence and front fence rail.
4. Adjust upper guide bearings and lower guide blocks away from the blade.
5. Open the upper and lower wheel covers and slide the blade off both wheels. Use caution, the blades are sharp!
6. Maneuver the blade through the table slot then turn it 90˚ to move the blade between the fence rail and the table.

To replace the blade, ensure that the power is dis-connected and:

1. Slide the blade behind the fence rail and through the table slot, ensuring that the teeth are pointing down toward the table.
   If the teeth will not point downward in any ori-entation, the blade is inside out. See Figure 10 for typical blade geometry. Put on heavy gloves, remove the blade, and twist it until it is right side out. Re-install the blade.

2. Slip the blade through the upper and lower guides and mount over the upper and lower wheels.

3. Apply tension to the blade by turning the tension control knob. Refer to blade ten-sioning instructions earlier in this section.

4. Rotate the upper wheel manually and check blade tracking.

5. Adjust the upper guide bearings and lower guide blocks as described earlier in this section.

6. Close the wheel covers. Turn the yellow guard locking knobs to lock them shut.

7. Replace the table insert and table pin, being sure not to use excessive force.

8. Replace the fence rail and fence.

WARNING
Use extreme caution when replacing blades. Teeth are dangerously sharp and coiled blades are prone to spring when released from their packaging. Use gloves and safety glasses or goggles whenever handling blades. Failure to do so could result in seri-ous personal injury.

Changing Speeds

The G7211/G7212 24″ Bandsaw provides two speeds, 2800 and 3500 FPM, to make cutting easier. In many applications, blade speed is a matter of personal preference. Usually the higher speed will produce the best results, but if the motor is straining while cutting, try a slower blade speed. Blade speed is also affected by the type of wood, denser woods need a different speed than a softer, lighter wood. Ultimately blade speed is a matter of trial and error. Whenever possible test the cut on a scrap piece first to gauge how well the blade is cutting at the selected speed.

To change bandsaw speeds:

1. Turn the bandsaw power switch off and dis-connect from power source.
2. Use a 9⁄16″ open end wrench to loosen the lock nut and lock bolt on the lock system. See Figure 11. This provides room to turn the adjuster nut.
3. Use a 3⁄4″ box wrench to loosen the adjuster nut. Loosen as needed to allow the shaft to move. See Figure 12.
4. Select the pulleys for the speed desired. The rear or smaller motor pulley provides the slower, 2800 FPM, speed, while the front pulleys are for the faster 3500 FPM speed. See Figure 13.
5. Move the V-belt to the pair of pulleys which provide the desired speed.
6. Tighten the belt by sliding the adjuster nut and shaft up or down as needed.
7. Tighten the adjuster nut.
8. Bring the lock bolt head snug against the adjuster nut. Tighten the lock nut.

Ripping

Ripping is the process of cutting a board into two or more thinner boards. The maximum board width that can be ripped is limited by the distance between the blade and the support column. Maximum cutting width for this bandsaw is 24″.
The important consideration when ripping is blade selection. Generally, the wider the blade, the bet-ter. In most applications, a hook or skip tooth style will be sufficient. Also, since most ripped lumber will be planed or sanded smooth, you can choose blades with fewer teeth-per-inch. While blades with fewer teeth-per-inch produce rougher cuts, these types of blades offer larger gullet capacities for clearing sawdust, less heat buildup, and yield more horsepower per tooth.

To perform ripping operations:

1. The bandsaw must be adjusted correctly. See Blade Tension/Tracking section.
2. The table must be square to the blade. See Table Adjustment Section.
3. Use the widest blade available. The blade must also be in good condition.
4. Use a fence to guide work.
5. Draw a reference line on the edge of the board.
6. Support ends of the board if necessary.
7. Feed work slowly and evenly.

Stacked Cuts

One of the benefits of a bandsaw is its ability to cut multiple copies of a particular shape by stack-ing a number of workpieces together.
Before making stacked cuts, it is essential to ensure that both the table and the blade are prop-erly adjusted to 90°. Otherwise, any error will be compounded with each piece cut from the top to the bottom of the stack.

To complete a stacked cut:

1. Align your pieces from top to bottom to ensure that each piece has adequate scrap to provide a clean, unhampered cut.
2. Using brads in the waste portion of each piece, secure all the pieces together.
3. Lay out the shape you intend to cut on the face of the top piece.
4. Make relief cuts perpendicular to the outline of your intended shape in areas where changes in blade direction could strain the woodgrain or cause the blade kerf to bind.
5. Cut the stack of pieces as though you were cutting a single piece. Follow you layout line with the blade kerf on the waste side of your line.

Cutting Curves

When cutting curves, simultaneously feed and turn the stock carefully so that the blade follows the layout line without being twisted. If a curve is so abrupt that it would be necessary to repeated-ly back up and cut a new kerf, use either a nar-rower blade or a blade with more set to avoid that. A blade with more set can cut relatively tighter radii; however, the cut is usually rougher than cuts produced by blades with medium set.

Always make short cuts first, then proceed to the longer cuts. Relief cuts will also reduce the chance that the blade will be pinched or twisted. Relief cuts are cuts made through the waste por-tion of the workpiece and are stopped at the lay-out line. As you cut along the layout line, waste wood is released from the workpiece, alleviating any pressure on the back of the blade. Relief cuts also make backing the workpiece out easier, if needed. The table below lists blade widths for this bandsaw and corresponding minimum radii each blade will cut.

Resawing

Resawing is the process of cutting a board into two or more thinner boards. Each new board is the same width and length as the original board, but the thickness is less. The maximum board width that can be resawn is limited by the maxi-mum cutting height of the bandsaw. Maximum cutting height for this bandsaw is 153/4″.
Use common sense when resawing; attempting to resaw a board that is too wide or too dense may put excessive strain on the blade and be unsafe.

Again, the important consideration when resaw-ing is blade selection. When selecting a blade, keep in mind that generally, a wider blade is eas-ier to control. The blade should be of the best quality in order to handle the increased stress. In most applications a hook or skip tooth style will work fine. Also, since most resawn lumber will be planed smooth, you can choose blades with fewer teeth per inch (3 to 6). While blades with fewer teeth per inch produce rougher cuts, these types of blades offer larger gullet capacities for clearing sawdust, less heat build up, and yield more horsepower per tooth.

NOTE: When operating with wide blades, run the bandsaw at the slowest speed.

To resaw lumber, follow the procedure below:

1. The blade must be adjusted correctly.
2. The table must be square to the blade.
3. Use the widest blade that will fit this saw (11/4″). The blade must also be in good con-dition.
4. Use the fence to guide the work.
5. Support ends of the board if necessary.
6. Feed work slowly and evenly.

When using a fence to guide the board, the actu-al line of cut may not be parallel to the fence. In fact, most bandsaw blades will not cut exactly parallel to the fence (even when the fence is set parallel to the miter gauge slot). There are usual-ly a number of reasons for this:

1. Teeth are set unequally from side to side.
2. Teeth are dull on one side.
3. Blade tension is too tight or too loose.

IMPORTANT: Do not force the wood into the blade during cutting. This will distort the blade, cause excessive heat and often results in blade breakage as well as miscut lumber.

MAINTENANCE

Table
The table and other non-painted surfaces on the Model G7211/7212 should be protected against rust and pitting. Wiping the saw clean after every use ensures that moisture from wood dust isn’t allowed to trap moisture against bare metal sur-faces.
Some woodworkers recommend using automo-tive paste wax on exposed steel and cast iron sur-faces. The wax provides a layer of protection, as well as reducing friction between lumber and the table, making cuts faster and smoother. Avoid waxes that contain silicone or other synthetic ingredients. These materials can find their way into lumber that’s being worked, and can make staining and finishing difficult. If you use paste wax, make sure that it’s 100% Carnauba wax.

NOTICE
Do not use paraffin or similar waxes on your saw’s table. They can leave residues which will make cutting more difficult over time. Do not use silicon based lubricants. They can rub off onto the wood and prevent it from taking stains and finishes properly.

V-Belts
To ensure optimum power transmission from the motor to the blade, the V-belt must be in good condition and operate under proper tension. Belts should be checked for cracks, fraying and wear. Belt tension should be checked at least every 3 months; more often if the bandsaw is used daily.

The V-belts are accessed via the bottom cover:

1. Squeeze the center of each V-belt.
2. Note the amount of deflection. Deflection should be approximately 3⁄4″.

WARNING

• DO NOT make adjustments or attempt main-tenance procedures while the Model G7211/G7212 is running. Ensure that the switch is off, power is disconnected and moving parts have stopped before making adjustments. Failure to comply may result in serious personal injury.
• Operating this equipment has the potential to propel debris into the air which can cause eye injury. Always wear safety glasses or goggles when operating equipment. Everyday glasses or reading glasses only have impact resistant lenses, they are not safety glasses. Be certain the safety glasses you wear meet the appropriate standards of the American National Standards Institute (ANSI).

Lubrication
Shielded and pre-lubricated ball bearings require no lubrication for the life of the bearings. All bear-ings are standard sizes and replacements can be purchased from our parts department or bearing supply store.
As for other items on this machine, such as adjustment controls, an occasional “shot” of light oil is just about all that is necessary. Before apply-ing, however, wipe off any sawdust with a clean cloth, towel or dry paint brush and spray on the lubricant. Ensure that oil does not get on the pul-leys or V-belts because it could cause belt deteri-oration and slipping.

Miscellaneous

Always be aware of the condition of your bandsaw before using it. Routinely check the condition of the following items and repair or replace as nec- essary.

1. Loose mounting bolts.
2. Worn switch.
3. Worn or damaged blade.
4. Worn or damaged support bearings or guide bearings.
