Power Connection

Electrocution or fire may occur if machine is ungrounded, incorrectly connected to power, or connected to an undersized circuit. Use a qualified electrician to ensure a safe power connection.

Hardwire setups require power supply lines to be enclosed inside of conduit, which is securely mounted and constructed in adherence to applicable electrical codes.

A hardwire setup for this machine must be equipped with a locking disconnect switch as a means to disconnect the power during adjustments or maintenance, which is a typical requirement for many lock-out/tag-out safety programs.

Figure 1 shows a simple diagram of a hardwire setup with a locking disconnect switch between the power supply and the machine.

Revised Test Run Steps

Perform Steps 1–5 of Test Run on Page 25 in the owner’s manual. Then follow the steps below.

1. Press ON button to turn machine ON, and

observe blade movement.

To connect power supply wires to machine:

1. Remove cover from power supply junction

box.

2. Insert incoming power wires through strain

relief (see Figure 2) at bottom of junction box, connect wires to terminals shown below, then install junction box cover.

Note: When using a phase converter, connect

the manufactured power leg or "wild wire" to the terminal indicated in Figure 2). This terminal can handle power ﬂuctuation because it is wired directly to the motor. The other wires connect to the controls and must be consistent to prevent damage.

SAFETY

For Machines Mfd. Since 7/21

Additional Bandsaw Safety

Serious cuts, amputation, or death can occur from contact with the moving saw blade during operation or if blade breakage occurs. Serious injury or death can also occur from getting ﬁngers, hair, or clothing entangled in moving parts if the machine is operated while the doors are open. To reduce this risk, anyone operating this machine MUST completely heed the hazards and warnings below.

Hand Placement. Placing hands or fingers

in line with blade or too close to blade during operation may result in serious injury if hands slip or workpiece moves unexpectedly. Do not position fingers or hands in line with blade, and never reach under table while blade is moving.

Small/Narrow Workpieces. If hands slip during

a cut while holding small workpieces with fingers, serious personal injury or amputation may occur. Always support/ feed small or narrow workpieces with push sticks, push blocks, jig, vise, or some type of clamping fixture.

Blade Speed. Cutting workpiece before blade

is at full speed could cause blade to grab workpiece and pull hands into blade. Allow blade to reach full speed before starting cut. DO NOT start machine with workpiece contacting blade.

Feed Rate. To avoid risk of workpiece slipping

and causing operator injury, always feed stock evenly and smoothly. Do not force workpiece through the cut.

Blade Condition. Dull blades require more

effort to perform cut, increasing risk of accidents. Do not operate with dirty, dull, cracked or badly worn blades. Inspect blades for cracks and missing teeth before each use. Always maintain proper blade tension and tracking while operating.

Clearing Jams and Cutoffs. Always stop bandsaw

and disconnect power before clearing scrap pieces that get stuck between blade and table insert. Use brush or push stick, not hands, to clear cutoff scraps or clean chips from table.

Blade Control. To avoid risk of injury due to

blade contact, always allow blade to stop on its own. DO NOT try to stop or slow blade with your hand or the workpiece.

Guards/Covers. Blade guards and covers protect

operator from the moving bandsaw blade. The wheel covers protect operator from getting entangled with rotating wheels or other moving parts. ONLY operate this bandsaw with blade guard in proper position and wheel covers completely closed.

Upper Blade Guide Support. To minimize

exposure of operator to blade and provide maximum blade support while cutting, keep upper blade guides adjusted to just clear workpiece (approximately above workpiece).

Cutting Techniques. To avoid blade getting

pulled off wheels or accidentally breaking and striking operator, always turn bandsaw OFF and wait for blade to come to a complete stop before backing workpiece out of blade. DO NOT back workpiece away from blade while bandsaw is running. DO NOT force or twist blade while cutting, especially when sawing small curves. This could result in blade damage or breakage.

Workpiece Support. To maintain maximum

control and reduce risk of blade contact/ breakage, always ensure adequate support of long/large workpieces. Always keep workpiece flat and firm against table/fence when cutting to avoid loss of control. If necessary, use a jig or other work-holding device.

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed.

To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by a or qualified service personnel in accordance with applicable electrical codes and safety standards.

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result—especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the requirements in the following section.

Note: The circuit requirements in this manual are for machine will be running at a time. If this machine will be connected to a shared circuit where multiple machines will be running at the same time, consult a qualified electrician to ensure the circuit is properly sized.

A power supply circuit includes all electrical equipment between the main breaker box or fuse panel in your building and the incoming power connections inside the machine. This circuit must be safely sized to handle the full-load current that may be drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

This machine must be grounded! In the event of certain types of grounding provides a path of least resistance for electric current electric shock.

Improper connection of the equipmentgrounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipmentgrounding wire. If repair or replacement of the power cord or plug is necessary, do not connect the equipment-grounding wire to a live (current carrying) terminal.

Check with an electrician or qualiﬁ ed service personnel if you do not understand these grounding requirements, or if you are in doubt about whether the tool is properly grounded.

If you ever notice that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with a new one.

Dust Collection

This machine creates a lot of wood chips/ dust during operation. Breathing airborne dust on a regular basis can result in permanent respiratory illness. Reduce your risk by wearing a respirator and capturing the dust with a dust-collection system.

Minimum CFM at each Dust Port: 400 CFM

Do not confuse this CFM recommendation with the rating of the dust collector. To determine the CFM at the dust port, you must consider these variables: (1) CFM rating of the dust collector, (2) hose type and length between the dust collector and the machine, (3) number of branches or wyes, and (4) amount of other open lines throughout the system. Explaining how to calculate these variables is beyond the scope of this manual. Consult an expert or purchase a good dust collection "how-to" book.

To connect dust collection system to machine:

1. Fit a 4" dust hose over each dust port, and

secure them in place with hose clamps (see Figure 23).

Note: For best results, connect free ends of

hoses to a 4" Y-ﬁtting and secure with hose clamps, then connect ﬁtting to your dust collection system. See Accessories, beginning on Page 51, for more information.

Tug hoses to make sure they do not come off.

Adjustment Overview

The bandsaw is one of the most versatile woodworking machines. However, it has multiple components that must be properly adjusted for the best cutting results.

For practical and safety reasons, some adjustments and test operations must be performed before performing other necessary adjustments. Below is an overview of all the adjustments and the order in which they should be performed:

Bandsaw wheels are either flat or crowned and both shapes track differently. This bandsaw has crowned wheels. As the wheels spin, a properly tracking blade naturally tracks at the center of the wheel (see Figure 24).

PROPER TRACKING

Blade Centered

Blade

Centered

Figure 24. Blade centered on crown of wheel. Blade centered on crown of wheel.

Blade tracking is primarily affected by the tilt of the upper wheel, known as “center tracking.” However, the alignment of both wheels plays an important part as well (see Aligning Wheels on Page 63 for more details).

Wheel

Initial Blade Tracking

"Tracking" refers to how the blade rides on the bandsaw wheels. Proper tracking is important for maintaining bandsaw adjustments, achieving correct blade tension, and cutting accurately. Improper tracking reduces cutting accuracy, causes excess vibrations, and places stress on the blade and other bandsaw components. The shape of the wheels and the orientation of the wheels in relation to each other determine how the blade tracks.

The wheels on this bandsaw were aligned at the factory, so center tracking is the only adjustment that needs to be checked/performed when the saw is new.

Serious personal injury

can occur if the machine starts while your hand is touching the bandsaw wheel during tracking adjustments. Disconnect power from the bandsaw before performing blade tracking adjustments.

PREPARATION

Tensioning Blade

A properly tensioned blade is essential for making accurate cuts, maximizing blade life, and making other bandsaw adjustments. However, a properly tensioned blade will not compensate for cutting problems caused by excessive feed rate, hardness variations between workpieces, and improper blade selection.

Optimal cutting results for any type of workpiece are achieved through a combination of correct blade selection, proper blade tension, properly adjusted blade guides and other bandsaw components, and using an appropriate feed rate.

Improper blade tension is unsafe, produces inaccurate and inconsistent results, and introduces unnecessary wear on bandsaw components. Over-tensioning the blade increases the chance of the blade breaking or wheel misalignment. Under-tensioned blades wander excessively while cutting and will not track properly during operation.

The Flutter Method

Using the flutter method, you intentionally loosen the blade until it just passes the point of being too loose (when it begins to flutter). Then you gradually tighten the blade until proper tension is reached.

To tension bandsaw blade using ﬂutter method:

1. DISCONNECT MACHINE FROM POWER!

Make sure blade is properly tracking

as instructed in Initial Blade Tracking subsection on Page 22.

Raise guide post all the way, and move upper

and lower guide bearings away from blade (refer to Page 30 for more information).

Engage blade tension quick-release lever to

apply tension to blade.

Connect bandsaw to power, then turn it ON.

The method used to tension the blade is often a matter of preference. This manual describes two methods: the ﬂutter method and the deﬂection method. Either method will help you properly tension the blade. Experience and personal preference will help you decide which method you prefer.

Note: The tensioning done on the blade before the Test Run was an approximate tension. The following procedures ﬁne-tune the blade tension.

Use blade tension handwheel to slowly

decrease blade tension until you see blade start to flutter.

. Slowly increase tension until blade stops

fluttering, then tighten blade tension adjustment knob an additional turn.

The Deﬂection Method

The deflection method is much more subjective than the flutter method. Each blade will deflect differently and every user will determine what "moderate pressure" means. The following are general guidelines for tensioning the blade with this method.

To tension bandsaw blade using deﬂection method:

1. DISCONNECT MACHINE FROM POWER!

Make sure blade is properly tracking

as instructed in Initial Blade Tracking subsection on Page 22.

Raise guide post all the way and move upper

and lower guide bearings away from blade (refer to Page 30 for more information).

Engage blade tension quick-release lever to

apply tension to blade.

Fine-Tune Tracking

During setup, the blade was tracked without the machine connected to power (refer to Page 22). In this procedure, the bandsaw is turned ON to perform fine tuning of the tracking. Make small changes with the blade tracking knob as you monitor the effect on the blade tracking.

To ﬁne-tune blade tracking:

1. Close wheel covers and turn bandsaw ON.

Observe blade tracking path through clear

tracking window on right edge of bandsaw (see Figures 33–34).

5. Using moderate pressure, push center of

blade sideways.

— If blade deﬂects approximately 1⁄4", it is

properly tensioned. Proceed to Step 6.

— If blade deﬂects less than 1⁄4", it is

over-tensioned. Rotate blade tension handwheel counterclockwise two full turns and repeat Step 5.

— If blade deﬂects 1⁄4" or more, blade is not

properly tensioned. Rotate blade tension handwheel clockwise to incrementally tension blade, and repeat Step 5 until blade is properly tensioned.

6. Adjust blade guides as described in

Adjusting Blade

PREPARATION

Position support bearing approximately

0.016" away from back of blade, as illustrated in Figure 36.

Support Bearings

The support bearings are positioned behind the blade near the blade guides and prevent the blade from pushing backward during cutting operations. Proper adjustment of the support bearings helps you make accurate cuts and prevents the blade teeth from coming in contact with the blade guides while cutting. If this happens, the blade "tooth set" can be ruined, which will greatly reduce the blade's ability to make good cuts.

There are support bearings on the upper and lower blade guide assemblies. Both adjust in a similar manner. The following instructions refer to the upper support bearings.

Note: The main purpose of this adjustment

is to prevent the blade from being pushed backward far enough that the blade guides will contact (and ruin) the "tooth set" of the blade during cutting operations.

OPERATION

Basic Functions of a Bandsaw

A properly adjusted bandsaw can be safer to operate than most other saws and performs many types of cuts with ease and accuracy. It is capable

of performing the following types of cuts:

Straight Cuts

• Miters

• Angles

• Compound Angles

• Resawing

• Ripping

• Crosscutting

Irregular Cuts

• Simple and Complex Curves

• Duplicate Parts

• Circles

• Beveled Curves

Basic Cutting Tips

Here are some basic tips to follow when operating the bandsaw:

• Replace, sharpen, and clean blades often for best performance. Check guides, tension, and alignment settings periodically and adjust when necessary to keep the saw running in top condition.

• Use light and even pressure while cutting. Light feeding pressure makes it easier to cut straight, reduces blade lead, and prevents undue friction or strain on the bandsaw components and the blade.

• Avoid twisting the blade when cutting around tight corners. Allow the blade to saw its way around the corners. Always use relief cuts when possible.

• Misusing the saw or using incorrect techniques (e.g. twisting the blade with the workpiece, incorrect feed rate, etc.) is unsafe and results in poor cuts.

Workpiece Inspection

Some workpieces are not safe to cut or may require modification before they are safe to cut.

Before cutting, inspect all workpieces for the following:

• Material Type: This machine is intended

for cutting natural and man-made wood products, laminate covered wood products, and some plastics. Cutting drywall or cementious backer board creates extremely ﬁne dust and may reduce the life of the bearings. This machine is NOT designed to cut metal, glass, stone, tile, etc.; cutting these materials with a bandsaw may lead to injury.

• Foreign Objects: Nails, staples, dirt, rocks

and other foreign objects are often embedded in wood. While cutting, these objects can become dislodged and hit the operator, cause kickback, or break the blade, which might then fly apart. Always visually inspect your workpiece for these items. If they can't be removed, DO NOT cut the workpiece.

• Large/Loose Knots: Loose knots can become

dislodged during the cutting operation. Large knots can cause kickback and machine damage. Choose workpieces that do not have large/loose knots or plan ahead to avoid cutting through them.

• Wet or "Green" Stock: Cutting wood with

a moisture content over 20% causes unnecessary wear on the blades, increases the risk of kickback, and yields poor results.

• Excessive Warping: Workpieces with

excessive cupping, bowing, or twisting are often dangerous to cut because they can be unstable and unpredictable when being cut. DO NOT use workpieces with these characteristics!

• Minor Warping: Workpieces with slight

cupping can be safely supported if the cupped side is facing the table or the fence. On the contrary, a workpiece supported on the bowed side will rock during a cut and could cause kickback or severe injury.

Blade Length

Measured by the blade circumference, blade lengths are specific to each bandsaw. They are determined by the wheel diameter and distance between the wheels. Blades will vary slightly even in the same length because of how they are welded. Refer to Accessories on Page 51 for replacement blades from Grizzly.

Blade Width

Measured from the back of the blade to the tip of the blade tooth (the widest point), blade width is often the ﬁrst consideration given to blade selection. Blade width dictates the largest and smallest curve that can be cut, as well as how accurately it can cut a straight line.

• Straight Cutting: Use the largest width blade

that you own. Large blades excel at cutting straight lines and are less prone to wander (known as blade lead —refer to Page 49 for more information on blade lead).

Tooth Style

Figure 55 illustrates the three main blade tooth styles:

Raker Skip Hook

• Curve Cutting: Use the chart in Figure 54 to determine the correct blade for curve cutting. Determine the smallest radius curve that will be cut on your workpiece and use the corresponding blade width (refer to Cutting Curves on Page 48 for more information).

• Raker: Considered to be the standard because

the tooth size and shape are the same as the tooth gullet. The teeth on raker blades usually are very numerous, have no angle, and produce cuts by scraping the material. As a result, smooth cuts can be achieved without cutting fast or generating more heat than other tooth types.

• Skip: Similar to a raker blade, except that

it is missing every other tooth. Because of the design, skip toothed blades have a much larger gullet than raker blades, and therefore, cut faster and generate less heat. However, these blades also leave a rougher cut than raker blades.

• Hook: The teeth have a positive angle

(downward) which makes them dig into the material, and the gullets are usually rounded for easier waste removal. These blades are excellent for the tough demands of resawing and ripping thick material.

Tooth Pitch

Measured as TPI (teeth per inch), tooth pitch determines the number of teeth. More teeth per inch (fine pitch) will cut slower, but smoother; while fewer teeth per inch (coarse pitch) will cut rougher, but faster. As a general rule, choose blades that will have at least two teeth in the material at all times. Use fine-pitched blades on harder woods and coarse-pitched blades on softer woods.

Tooth Set

Two common tooth sets for wood bandsaw blades are alternate and raker. Each different type of tooth set removes material in a different manner, leaving cuts with different characteristics (see Figure 56).

Blade Material

Bandsaw blades must meet two requirements: flexibility and hardness. The flexibility of a blade allows it to travel on the wheel as a band, while hardness allows the teeth to cut and hold an edge. Modern material technology has allowed bandsaw blades to meet these requirements in various ways.

Carbon Steel: These blades are differentially heat treated to provide hard teeth that will hold an edge, and yet be flexible in the back.

Carbide Tooth: Extremely hard carbide is either welded onto or impregnated into the carbon steel blades, providing superior edge-holding characteristics (see Figure 57).

Alternate Raker

• Alternate: An all-purpose arrangement where the teeth are bent evenly left and right of the blade.

Blade Care & Break-In

Blade Care

A bandsaw blade is a thin piece of steel that is subjected to tremendous strain. You can obtain longer use from a bandsaw blade if you give it fair treatment and always use the appropriate feed rate for your operation.

Be sure to select blades with the proper width, set, type, and pitch for each application. Using the wrong blade will produce unnecessary heat and shorten the life of the blade.

A clean blade will perform much better than a dirty blade. Dirty or gummed up blades pass through the cutting material with much more resistance than clean blades. This extra resistance also causes unnecessary heat.

Blade Break-In

The tooth tips and edges of a new blade are extremely sharp, and cutting at too fast of a feed rate fractures the beveled edges of the teeth and causes premature blade wear.

Blade Breakage

Many conditions may cause a bandsaw blade to break. Blade breakage is unavoidable in some cases, since it is the natural result of the peculiar stresses that bandsaw blades are subjected to.

Blade breakage is also due to avoidable circumstances. Avoidable blade 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 breakage are:

• Faulty alignment or adjustment of the blade guides.

• Forcing or twisting a wide blade around a short radius.

• Feeding the workpiece too fast.

• Dull or damaged teeth.

• Over-tensioned blade.

To properly break in a new blade:

1. Choose correct speed for blade and material

of operation.

Reduce feed pressure by half for first

50–100 in2 of material cut.

To avoid twisting blade when cutting, adjust

feed pressure when total width of blade is in cut.

• Upper blade guide assembly set too high above the workpiece. Adjust the top blade guide assembly so that there is approximately the assembly and the workpiece.

• Using a blade with a lumpy or improperly finished braze or weld.

• Leaving the blade tensioned when not in use.

• Using the wrong pitch (TPI) for the workpiece thickness. The general rule of thumb is to have no less than two teeth in contact with the workpiece at all times during cutting.

Ripping

"Ripping" means cutting with the grain of the wood stock. For plywood and other processed wood, ripping simply means cutting down the length of the workpiece. Beveled rip cuts may be performed by tilting the table.

To make a rip cut:

1. Adjust fence to match width of cut on your

workpiece, then lock fence in place.

Adjust blade guide assembly to proper height

above workpiece.

After all safety precautions have been met,

turn bandsaw ON and wait for it to come to full speed. Slowly feed workpiece into blade until blade is completely through workpiece. Figure 67 shows an example of a ripping operation.

Re-check table to make sure it is square to

the blade. If necessary, repeat this procedure until you are satisfied.

OPERATION

Crosscutting

Crosscutting is the process of cutting across the grain of wood. For plywood and other processed wood, crosscutting simply means cutting across the width of the material. Crosscuts can be 90° or angled using the miter gauge. Compound crosscuts are those where the miter is angled and the table tilted.

To make a crosscut:

1. Mark workpiece on edge where you want to

begin cut.

Adjust blade guide assembly to proper height

above workpiece.

Adjust miter gauge to correct angle needed

for cut.

Move fence out of the way. Place workpiece

evenly against miter gauge, then line up mark with blade.

After all safety precautions have been met,

turn bandsaw ON and wait for it to come to full speed. Slowly feed workpiece into blade until blade is all the way through workpiece. Figure 68 shows an example of a crosscutting operation.

Resawing

"Resawing" means cutting the thickness of a board into two or more thinner boards (see Figure 69 for an example). The maximum height of a board that can be resawn is limited by the maximum cutting height of the bandsaw.

Figure 69. Example of a resawing operation. Example of a resawing operation.

One of the most important considerations for resawing is blade selection—a wide blade cuts straighter and is less prone to blade lead (see Blade Lead on Page 49 for more information).

For most applications, use a blade with a hook or a skip tooth style. Choose blades with fewer teeth-per-inch (from 3 to 6 TPI), because they offer larger gullet capacities for clearing sawdust, which reduces heat buildup and strain on the motor.

Figure 68. Example of a crosscutting operation with Example of a crosscutting operation with

the miter gauge.the miter gauge.

When resawing thin pieces, a wandering blade (blade lead) can tear through the side of the workpiece, exposing your hands to the blade teeth. Always use push blocks when resawing and keep your hands clear of the blade.

Cutting Curves

When cutting curves, simultaneously feed and turn the stock carefully so the blade follows the layout line without twisting. If curves are sharp or tight, use a narrower blade with more TPI (teeth per inch) and make relief cuts to avoid having to back the workpiece away from the blade.

Always make short cuts first, then proceed to the longer cuts. Relief cuts reduce the chance of the blade being pinched or twisted. Relief cuts are cuts made through the waste portion of the workpiece and are stopped at the layout line, so when you're cutting along the layout line, waste wood is released from the workpiece, alleviating any pressure on the back of the blade. Relief cuts also make it easier to back the workpiece out once the saw blade has come to a stop, if needed.

The list below displays blade widths and the corresponding minimum radii for those blade widths.

Stacked Cuts

One of the beneﬁts of a bandsaw is its ability to cut multiple copies of a particular shape by stacking a number of workpieces together. However, before making stacked cuts, ensure that the table is perpendicular (90°) to the blade—otherwise, any error in this setting will be compounded in the workpieces.

To complete a stacked cut:

1. Align workpieces from top to bottom.

2. Secure all pieces together in a manner that

will not interfere with cutting. Hot gluing along edges works well, as does brad nailing through waste portion. (Be careful not to cut into brads or you may break blade!)

Lay out shape you intend to cut on face of

top piece.

4. Make relief cuts perpendicular to outline of

your intended shape in areas where changes in blade direction could strain woodgrain or cause blade to bind.

Cut stack of pieces along your layout line as

though you were cutting a single piece (see Figure 70 for an example of a stacked cut setup).

Skewing Fence

Cut a straight and parallel wood board

approximately 3⁄4" thick x 3" wide x 16" long.

Tip: Cut your board out of a new piece of 3⁄4"

plywood, using a table saw. The straight "factory edge" of the plywood will ensure accuracy during the following steps. Alternatively, you can use a jointer and table saw to straighten a piece of scrap wood.

On wide face of board, draw a straight line

parallel to long edge, similar to layout line shown in Figure 72.

Slide fence out of the way and cut along

layout line halfway through board. Turn bandsaw OFF and wait for blade to stop. Do not move board.

Clamp board to bandsaw table, then slide

fence over to board so it barely touches one edge of board.

5. Adjust the four fence set screws (see Figure

73) to skew the fence so that it is parallel

with the wood board, contacting it evenly along its length.

T1194—Resaw Fence w/Drift Bar

Anyone who's ever tried to rip or resaw on a bandsaw without adjusting for blade drift knows the natural line of cut is not always parallel to the fence. Forcing the wood against the fence will put strain on the blade and cause a wandering cut line. The easiest way to compensate for blade drive is to scribe a cut line on the edge or face of your workpiece and use a drift bar mounted to your fence. The drift bar acts as a thickness gauge and adjusts the angle of cut with the scribed line, ensuring a uniform thickness without putting undue strain on the blade. This includes the 19 drift bar so you have everything you need to start cutting down on drift!

MAINTENANCE

Maintenance Schedule

Always disconnect machine from power before performing maintenance or serious personal injury may result.

For optimum performance from your machine, follow this maintenance schedule and refer to any speciﬁc instructions given in this section.

To minimize your risk of injury and maintain proper machine operation, shut down the machine immediately if you ever observe any of the items below, and ﬁx the problem before continuing operations:

Ongoing

• Loose mounting bolts.

• Worn or damaged saw blade. Worn or damaged wires.

•

• Check/clean wheel brushes.

• Clean/protect table surface.

• Check lubrication points.

• Any other unsafe condition.

For Machines Mfd. Since 7/21

Cleaning & Protecting

Cleaning the bandsaw is relatively easy. Vacuum excess wood chips and sawdust, and wipe off the remaining dust with a dry cloth. If any resin has built up, use a resin dissolving cleaner to remove it.

Protect the unpainted cast-iron surfaces on the table by wiping it clean after every use— this ensures moisture from wood dust does not remain on bare metal surfaces. Keep the table rust-free with regular applications of products like G96 T-9 (see Accessories section for more details).

Gun Treatment, SLIPIT®, or Boeshield®

Lubrication

An essential part of lubrication is cleaning the components before lubricating them. This step is critical because dust and chips build up on lubricated components, which makes them hard to move. Simply adding more grease to built-up grime will not result in smooth moving parts. Clean the components in this section with an oil/ grease solvent cleaner or mineral spirits before applying lubrication.

Monthly Check

• V-belt tension, damage, or wear.

• Clean/vacuum dust build-up from inside

cabinet and off motor.

Wheel Brushes

The bandsaw is equipped with lower wheel brushes to keep saw dust from building up on the tire. The brushes should be checked daily and cleaned when they become dirty.

There are adjustment brackets that allow the brushes to be adjusted for bristle wear (refer to Adjusting Wheel Brushes on Page 59 for detailed instructions).

All bearings are sealed and permanently lubricated. Leave them alone until they need to be replaced.

Aligning Wheels

The following adjustment was performed at the factory and should not need to be performed again unless there is a wheel alignment problem, or one or more wheels are replaced.

When wheels are coplanar (see F igure 102), the bandsaw is more likely to cut straight without wandering; and vibration, heat, and blade wear are considerably decreased because the blade is automatically balanced on the wheel.

Bringing the wheel into alignment may require a combination of shimming a wheel and adjusting the position of the lower wheel shaft.

Shimming a Wheel

When the wheels are parallel but not coplanar, one of the wheels must be shimmed out to bring it into the same plane as the other wheel.

Tip: Standard washers work well for shimming a wheel because they can easily be stacked to get the desired height.

To shim a wheel:

1. DISCONNECT MACHINE FROM POWER!

Adjust upper wheel tracking so that it is

parallel with lower wheel.

With coplanarity gauge touching both rims

of wheel that does not need to be shimmed out, measure distance away from other wheel with a fine ruler (see Figure 106). The distance measured with ruler is distance this wheel must be shimmed.

8. Perform previous Checking Wheel

Alignment procedure, beginning on Page 63,

and adjust wheels as necessary make them parallel and coplanar.

Tip: The ﬁrst time you get the wheels

coplanar, place a mark on each wheel where you held the coplanarity gauge, then use this position again in the future if you need to repeat the procedure. This assures repeated accuracy every time you adjust the wheels.

— If no further adjustments are necessary,

remove blade, re-install table, and then re-install blade.

— If the lower wheel is tilted in relation to

the upper wheel, proceed to Adjusting Lower Wheel Shaft Position.

Adjusting Lower Wheel Shaft Position

If the lower wheel is tilted in relation to the upper wheel, perform the following procedure to make it coplanar with the upper wheel.

Remove blade.

Remove wheel to be shimmed. Place as many

shims as necessary to correct gap measured in Step 3 onto wheel shaft.

Re-install and secure wheel.

7. Re-install blade (refer to Changing Blade

on Page 43) and properly tension and track blade.

There are four adjustment bolts with hex nuts in the lower wheel adjustment hub, shown in Figure

107. These adjust the wheel tilt from side to side and up and down.

Note: If you make a mistake during the following procedure, it can be very difﬁcult to correct. Therefore, it is important to double check wheel alignment (see Page 63), and troubleshoot all other possible solutions (see Troubleshooting) prior to adjusting the lower wheel shaft position.
