Clean Up

The unpainted surfaces are coated with a waxy oil to prevent corrosion during shipment. Remove this protective coating with a solvent cleaner or citrus-based degreaser such as Grizzly’s G7895

Degreaser. For thorough cleaning, some parts must be removed. For optimum performance from your machine, clean all moving parts or sliding contact surfaces.

Avoid chlorine-based solvents, such as acetone or brake parts cleaner that may damage painted surfaces. Always follow the manufacturer’s instructions when using any type of cleaning product.

Gasoline and petroleum products have low flash points and can explode or cause fire if used to clean machinery. DO

NOT use these products to clean the machinery.

Site Considerations

Floor Load

Refer to the Machine Data Sheet for the weight and footprint specifications of your machine.

Some residential floors may require additional reinforcement to support both the machine and operator.

Placement Location

Consider existing and anticipated needs, size of material to be processed through each machine, and space for auxiliary stands, work tables or other machinery when establishing a location for your new machine. See Figure 4 for the minimum working clearances.

��

Many cleaning solvents are toxic if inhaled.

Minimize your risk by only using these products in a well ventilated area.

G7895—Grizzly Citrus Degreaser

This natural, citrus-based degreaser is a great solution for removing export grease, and it’s much safer to work around than nasty solvents.

Figure 4.

Minimum working clearances.

Children and visitors may be seriously injured if unsupervised. Lock all entrances to the shop when you are away.

DO NOT allow unsupervised children or visitors in your shop at any time!

Dust Collection

This saw creates substantial amounts of fine dust while operating. Failure to use a vacuum system can result in respiratory illness.

Connect this machine to a shop vacuum rather than a dust collector. Most dust collectors are not designed to capture metal shavings and doing so may lead to a fire. If you are in doubt about the capabilities of your shop vacuum or dust collector, refer the owner's manual before connecting it to this machine.

To connect a vacuum hose:

Fit the 2 1 ⁄

" dust hose over the dust port, as shown in Figure 18 , and secure in place with a hose clamp.

Tug the hose to make sure it is snug.

Note: A tight fit is necessary for proper performance.

Figure 18.

3. Close stand door and fasten it shut with the stand door knob.

Blade Tracking

"Blade Tracking" refers to how the blade rides on the wheels. When tracking correctly, the blade rides in the center of the rim part of the wheels.

Blade tracking is primarily controlled by adjusting the upper wheel tilt. Tracking the blade in this manner is referred to as "Center Tracking," because you tilt the wheel until the blade rides in the center.

Another way to track the blade is known as

"Coplanar Tracking." Coplanar tracking involves aligning the wheels so they are parallel and aligned (see Wheel Alignment on Page 42 ).

When wheels are coplanar, vibration and heat are reduced during operation.

The wheels on the Model G0621 are factory aligned, so center tracking is the only adjustment that needs to be performed during setup.

To center track the blade:

1. DISCONNECT BANDSAW FROM POWER!

Adjust the upper/lower blade guides and support bearings away from the blade.

Open the upper wheel cover.

Adjust the blade tension by matching the size of the installed blade with the equivalent mark on the blade tension scale (located on the back of the bandsaw).

Spin the upper wheel by hand at least three times and watch how the blade rides on the crown of the wheel. Refer to Figure 19 for an illustration of this concept.

—If the blade rides on the peak of the upper wheel crown, then the bandsaw is already tracked properly and no additional adjustments are needed. Skip to Step 9 .

—If the blade does not ride in the peak of the upper wheel crown, then continue with the next step.

G0621 Wood/Metal Bandsaw -17-

Blade Centered on Peak of Crown

If, during the test run, you cannot easily locate the source of an unusual noise or vibration, stop the machine immediately, then review

Troubleshooting on Page 37 .

If you still cannot remedy a problem, contact our

Tech Support at (570) 546-9663 for assistance.

CENTER TRACKING

Figure 19.

Center tracking profiles.

Loosen the lock nut on the blade tracking knob threads so the blade tracking knob will rotate for adjustments.

Spin the upper wheel with one hand and rotate the blade tracking knob with the other hand to make the blade ride in the center of the bandsaw wheel tire.

When the blade consistently rides in the center of the wheel, tighten the tracking control lock nut.

Close the upper wheel cover.

Note: For the best performance from your saw, regularly maintain proper blade tracking.

NOTICE

Changes in the blade tension may change the blade tracking.

Test Run

Once assembly is complete and you have performed the Blade Tracking steps on Page 17 , test run the machine before continuing with the remainder of the adjustments.

-18-

Wear safety glasses during the entire test run process. Failure to comply may result in serious personal injury.

To test run the machine:

Read the Safety section beginning on Page

6 and read Basic Controls on Page 24 .

Connect the machine to the power source.

Turn the speed dial counterclockwise as far as it will go.

Lift the STOP paddle on the power switch and press the STOP button all the way in

(this resets the safety mechanism on the

STOP switch).

Turn the power ON by pressing the green ON button above the STOP paddle. The digital display should light up. If not, make sure the power STOP switch has been reset; otherwise, check the electrical connections and power source.

Press the ON button located on the motor control switch, then slowly turn the speed dial clockwise.

Listen to and watch for abnormal noises or actions. The machine should run smoothly with little or no vibration or rubbing noises.

— Strange or unusual noises must be investigated and corrected before operating the machine further. Always turn OFF the machine and disconnect it from power before investigating or correcting potential problems.

G0621 Wood/Metal Bandsaw

Tensioning Blade

A properly tensioned blade is essential for making accurate cuts and is a prerequisite for making many bandsaw adjustments. The blade tension is adjusted by rotating the blade tension lever.

To tension the bandsaw blade:

Make sure you have performed the Test Run instructions on the previous page and you are certain that the blade is tracking properly.

With the blade tension lever in the down

(engaged) position, adjust the blade tension until the mark on the blade tension scale matches the size of blade installed on the bandsaw.

Note: Because each blade is different and all blades stretch, this scale can only be considered as a general guide.

Turn the bandsaw ON .

Release the tension one quarter of a turn at a time. When the bandsaw blade starts to flutter, stop decreasing the tension.

Now, slowly increase the tension until the blade stops fluttering, then tighten the tension one more quarter of a turn.

Turn the bandsaw OFF and read the tension gauge. Use the reading as a guide when tensioning that blade in the future.

Note: Do not rely on this measurement for long periods of time because the blade will stretch with use.

NOTICE

To reduce blade stretching, remove the tension from the blade when not in use.

NOTICE

After blade tension and tracking are set correctly, properly adjust the upper/lower support bearings and guide-block assemblies into position before operating machine.

G0621 Wood/Metal Bandsaw

Adjusting Support

Bearings

The support bearings are positioned behind the blade to support it during cutting operations.

Proper adjustment of the support bearings is an important part of making accurate cuts and also keeps the blade teeth from hitting the blade guides during cuts.

To adjust the support bearings:

Make sure that the blade is tracking properly and that it is correctly tensioned.

2. DISCONNECT BANDSAW FROM POWER!

Familiarize yourself with the support bearing controls shown in Figure 20 .

Adjusting Blade

Guides

The blade guides provide side-to-side support to help keep the blade straight while cutting. The blade guides adjust in two ways—forward/backward and side-to-side. Properly adjusted blade guides are essential to making accurate cuts.

To adjust the upper and lower blade guides:

Make sure the blade tracks properly and is correctly tensioned.

NOTICE

The blade guides should not touch the blade after the dollar bill is removed.

NOTICE

Whenever changing a blade or adjusting tension and tracking, the upper and lower blade guides and guide-blocks must be readjusted before cutting operations.

Adjusting Positive

Stop

An adjustable positive stop allows the table to easily return to 90˚ after tilting.

To set the positive stop 90˚ to the blade:

Make sure the blade is correctly tensioned as described in the Tensioning Blade instructions on Page 19 .

2. DISCONNECT BANDSAW FROM POWER!

Loosen the two plastic knobs that secure the table to the trunnions.

Loosen the hex nut that locks the positive stop bolt in place.

Raise the upper blade guide assembly and place a 6" machinist’s square or try-square on the table next to the side of the blade as illustrated in Figure 27 . Adjust the positive stop bolt to raise or lower the table until the table is 90˚ to the blade.

Figure 27.

Squaring table to blade.

Secure the plastic knobs and lock the positive stop bolt by tightening the hex nut against the casting. Ensure that the bolt does not turn by holding it with another wrench while tightening the hex nut.

Setting Table

Tilt Scale to 0˚

The pointer on the table tilt scale must be calibrated in order for the scale reading to be accurate.

To calibrate the pointer on the table tilt scale:

Make sure the blade is tensioned/tracking correctly and that the table is 90˚ to the blade

(this procedure should be already completed with the Adjusting Positive Stop instructions).

Loosen the pointer screw.

Align the tip of the pointer with the 0˚ mark on the table tilt scale.

Tighten the pointer screw.

Aligning Table

To ensure cutting accuracy when the table is first installed, the table should be aligned so the miter slot is parallel to the bandsaw blade. This procedure works best with a 3 ⁄

" blade.

To align the miter slot parallel to the bandsaw blade:

Make sure the blade is tracking properly and that it is correctly tensioned.

2. DISCONNECT BANDSAW FROM POWER!

Loosen the trunnion bolts that secure the trunnions to the table.

Place an accurate straightedge along the blade. The straightedge should lightly touch both the front and back of the blade (the flat part only) without touching the blade teeth.

Use a fine ruler to gauge the distance between the straightedge and the miter slot. The distance you measure should be the same at both the front and back ends of the miter slot.

Adjust the table as needed until the distance between the blade and miter slot is equal at both ends.

Tighten the trunnion bolts.

Aligning Fence

To ensure cutting accuracy, the fence must be parallel with the miter slot.

To align the fence parallel with the miter slot:

If the fence is mounted on the left-hand side of the blade, remove it and remount it on the right-hand side of the blade.

Adjust the fence face parallel with the edge of the miter slot.

Loosen the two cap screws that mount the front rail to the table.

Place shims between the front rail and the table as necessary to make the fence parallel with the miter slot.

Note: Shim stock works well for this, but small pieces of paper can also work in a pinch.

5. Tighten the front rail mounting bolts.

NOTICE

Adjusting the fence parallel to the miter slot does not guarantee straight cuts. The miter slot may need to be adjusted parallel to the side of the blade. Refer to the Aligning Table instructions.

Workpiece

Inspection (Wood)

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

Before cutting wood, get in the habit of inspecting all workpieces for the following:

• 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 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 blade 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 blade and yields poor results.

• Excessive Warping: Workpieces with excessive cupping, bowing, or twisting are dangerous to cut because they are unstable and can move unpredictably when being cut. DO NOT use workpieces with these characteristics!

• Minor Warping: Workpieces with slight cupping can be safely supported if the cupped side faces the table or fence. On the contrary, a workpiece supported on the bowed side will rock during a cut, leading to loss of control.

Overview

The bandsaw is one of the most versatile wood cutting tools in the shop. 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

Follow these basic tips when operating the bandsaw:

• Keep the upper blade guide assembly adjusted to within 1" of the workpiece.

• Replace, sharpen, and clean blades as necessary. Make adjustments periodically to keep the saw running in top condition.

• Use light and even pressure while cutting.

Light contact with the blade makes it easier to follow lines and prevents extra friction.

• Avoid twisting the blade when cutting around tight corners. Allow the blade to saw around the corners.

• Misusing the saw or using incorrect techniques is unsafe and results in poor cuts.

Remember—the blade does the cutting with the operator’s guidance.

• Never start a cut with the blade in contact with the workpiece, and do not start a cut on a sharp edge.

G0621 Wood/Metal Bandsaw -25-

• When cutting metal, pay attention to the characteristics of the chips when cutting—they are good indicators of proper blade speed and feed rate. Figure 30 shows the basic chip characteristics and what they mean.

Chips are width of tooth, thin, curled, and silvery:

Optimum speed and feed rate.

Chips are silvery, thin, small, or powdery: Increase feed rate.

Chips are large, curled, blue or brown, or smoking:

Decrease feed rate.

Figure 30.

Reading chip characteristics.

Table Tilt

The bandsaw table tilts from -5˚ left to 45˚ right.

To tilt the table:

Loosen the two trunnion knobs underneath the table.

Tilt the table to the desired angle. (Refer to the angle gauge on the front table trunnion.)

Retighten both table-tunnion knobs.

NOTICE

The positive stop must be removed to move the table to the left.

Guide Post

The guide post (shown in Figure 31 ) connects the upper blade guide assembly to the bandsaw.

The guidepost allows the blade guide assembly to move up or down to be as close to the workpiece as possible. In order to cut accurately and safely, the bottom of the blade guide assembly must be no more than 1" from the workpiece at all times— this positioning provides the greatest blade support and minimizes the amount of moving blade exposed to the operator.

4 . Lock the guide post with the lock knob.

-26G0621 Wood/Metal Bandsaw

Ripping

When cutting wood, "Ripping" means cutting with the grain. For plywood or metal, ripping simply means cutting down the length of the workpiece.

To make a rip cut:

Adjust the fence to match the width of the cut on your workpiece, then lock the fence in place.

Adjust the blade guide assembly to less than

1" away from the workpiece.

After all safety precautions have been met, turn the bandsaw ON . Slowly feed the workpiece into the blade and continue with the cut until the blade is completely through the workpiece. Figure 32 shows a typical ripping operation.

Note: If you cut narrow pieces, use a push stick to protect your fingers.

Crosscutting

"Crosscutting" means cutting across the grain of wood. For plywood or metal, crosscutting simply means cutting across the width of the workpiece.

To make a 90˚ crosscut:

Mark the workpiece on the edge where you want to begin the cut.

Adjust the blade guide assembly to to less than 1" away from the workpiece and make sure the miter gauge is set to 90°.

Move the fence out of the way. Place the workpiece evenly against the miter gauge.

Hold the workpiece against the miter gauge and align the mark with the blade.

After all safety precautions have been met, turn the bandsaw ON . Slowly feed the workpiece into the blade and continue the cut until the blade is all the way through the workpiece. Figure 33 shows a typical crosscutting operation.

Figure 32.

Typical ripping operation.

NEVER place fingers or hands in the line of cut. If you slip, your hands or fingers may go into the blade. ALWAYS use a push stick when ripping narrow pieces. Failure to follow these warnings may result in serious personal injury!

G0621 Wood/Metal Bandsaw

Figure 33.

Typical crosscutting operation.

-27-

Resawing

"Resawing" ( Figure 34 ) means cutting the workpiece into two or more thinner workpieces.

One of the most important considerations for resawing is blade selection—a wide blade cuts straighter and is less prone to blade lead (see

Page 41 for more info on blade lead).

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

To resaw a workpiece:

Verify that the bandsaw is setup properly and that the table is perpendicular to the blade.

Use the widest blade your bandsaw will accept. Note: The blade must also be sharp and clean.

Adjust the fence to the desired width of cut, and lock it in place.

NOTICE

The scale on the front rail will NOT be accurate when using the resaw fence.

Support the ends of the board if necessary.

Turn the bandsaw ON .

Using push paddles and a push stick, maintain workpiece pressure against the fence and table, and slowly feed the workpiece into the moving blade until the blade is completely through the workpiece (see Figure 34 ).

Figure 34. Typical resawing operation.

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.

-28G0621 Wood/Metal Bandsaw

Cutting Curves

When cutting curves, simultaneously feed and turn the stock carefully so the blade follows the layout line without twisting. If a curve is so abrupt that it is necessary to repeatedly back up and cut a new kerf, use a narrower blade, a blade with more TPI (teeth per inch), or make more relief cuts.

Relief cuts are made through the waste portion of the workpiece and stop at the layout line. Relief cuts reduce the chance that the blade will be pinched or twisted during the cut.

The list below shows the minimum radius that can be cut by common blade widths.

Stacked Cuts

One of the benefits of a bandsaw is its ability to cut multiple copies of a particular shape by stacking workpieces together and cutting them as one.

Before making stacked cuts, ensure that both the table and the blade are properly adjusted to 90°; otherwise, any error will be compounded.

To complete a stacked cut:

Align your pieces from top-to-bottom to ensure that each piece has adequate scrap to provide a clean, unhampered cut.

Secure all the pieces together in a manner that will not interfere with the cutting. For wood, hot glue on the edges works well, as do brad nails through the waste portion. (Be careful not to cut into the brads or you may break the blade!)

On the face of the top piece, mark the shape you intend to cut.

Make relief cuts perpendicular to the outline of your intended shape in areas where changes in blade direction could cause the blade to bind.

Cut the stack of pieces as though you were cutting a single piece. Follow your layout line with the blade kerf on the waste side of your line as shown in Figure 36 .

G0621 Wood/Metal Bandsaw

Blade Selection

(Wood Cutting)

Selecting the right blade for the cut requires a knowledge of various blade characteristics.

Blade Length

Measured by the circumference, blade lengths are usually unique to the brand of your bandsaw and the distance between wheels. The Model

G0621 uses 108" long blades. Refer to Page 35 for blade replacements.

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.

The Model G0621 uses blades from 1 ⁄

" to 1" in width. Always pick the size of blade that best suits your application.

• Curve Cutting: Use the chart in Figure 35 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.

• Straight Cutting : Use the largest width blade that you own. Narrow blades can cut tight curves (a small radius) but are not very good at cutting straight lines because they naturally wander (blade lead). Large blades excel at cutting straight lines and are less prone to wander.

Tooth Style

When selecting blades, another option to consider is the shape, gullet size, teeth set and teeth angle—otherwise known as “Tooth Style."

Figure 37 illustrates the three main categories of tooth style:

Raker Skip Hook

Figure 37.

Raker, Skip & Hook tooth styles.

• Raker: This style is 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; these characteristics result in very smooth cuts, but do not cut fast and generate more heat than other types while cutting.

• Skip: This style is similar to a raker blade that 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 on this style 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.

-30G0621 Wood/Metal Bandsaw

Tooth Pitch

Usually measured as TPI (teeth per inch), tooth pitch determines the size/number of the 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 three teeth in the material at all times. Use fine pitched blades on harder woods and coarse pitched blades on softer woods.

Blade Care

A bandsaw blade is a delicate 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, style, and pitch for each application. The wrong choice of blades will often produce unnecessary heat which will shorten the life of your 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. Grizzly sells resin/pitch dissolving cleaners that are excellent for cleaning dirty blades.

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 must endure. Blade breakage is also due to avoidable circumstances.

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 breakage are:

• Faulty alignment/adjustment of the guides.

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

• Feeding the workpiece too fast.

• Dull teeth or damaged tooth sufficient set.

• Overtensioned blade.

• Top blade guide assembly set too high above the workpiece.

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

• Continuously running the bandsaw when not in use.

• Leaving blade tensioned when not in use.

• Using the wrong TPI for the workpiece thickness. (The general rule of thumb is 3 teeth in the workpiece at all times.)

G0621 Wood/Metal Bandsaw -31-

Blade Selection

(Metal Cutting)

Selecting the right blade for the job depends on a variety of factors, such as the type of material being cut, hardness of the material, material shape machine capability, and operator technique.

The chart below is a basic starting point for choosing blade type based on teeth per inch (TPI) for variable tooth pitch blades and for standard raker type bi-metal blades/HSS blades. However, for exact specifications of bandsaw blades, contact the blade manufacturer.

To select the correct blade TPI:

Measure the material thickness. This measurement is the length of cut taken from where the tooth enters the workpiece, sweeps through, and exits the workpiece.

Refer to the "Material Width/Diameter" row of the blade selection chart in Figure 38 and read across to find the workpiece thickness you need to cut.

Refer to the "Material Shapes" row and find the shape and material to be cut.

In the applicable row, read across to the right and find the box where the row and column intersect. Listed in the box is the minimum

TPI recommended for the variable tooth pitch blades.

The "Cutting Speed Rate Recommendation" section of the charts offers guidelines for various metals, given in feet per minute (speed

FPM) and meters per minute in parenthesis.

Choose the speed closest to the number shown in the chart.

Blade Changes

Turn the tension knob until proper blade tension has been reached according to the blade thickness scale shown in Figure 39 .

Always disconnect power to the machine when changing blades. Failure to do this may result in serious personal injury.

All saw blades are dangerous and may cause personal injury. To reduce the risk of being injured, wear leather gloves when handling saw blades.

To replace the blade:

1. DISCONNECT BANDSAW FROM POWER!

Release the tension lever.

Remove the table insert and the table pin.

Adjust the upper and lower guide blocks away from the blade.

Open the upper and lower wheel covers and slide the blade off both wheels.

Rotate the blade 90˚ and slide it through the slot in the table.

Slide the blade through the table slot, ensuring that the teeth are pointing down toward the table. If the teeth will not point downward in any orientation, the blade is inside-out. Put on heavy gloves, remove the blade, and twist it rightside-out.

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

Apply tension.

G0621 Wood/Metal Bandsaw -33-

Scale Calibration

You may need to recalibrate the fence scale after changing or adjusting the blade, or if the scale is not producing accurate cuts. Recalibrate the fence scale by adjusting the hairline indicator on the fence and testing your adjustment by cutting a piece of scrap wood.

To calibrate the scale:

Set the fence anywhere along the scale and locate a piece of scrap wood with at least one straight edge. Joint the edge with a jointer (if needed) to make the edge straight.

Hold the straight edge of the workpiece firmly against the fence, and feed the workpiece through the saw blade with a push stick.

Measure the width of the cut workpiece. The width of the workpiece should match the reading on the fence scale.

If the reading on the scale is not the same as the width of the cut workpiece, loosen the screws on the magnifying window ( Figure

40 ) and adjust it to match the width of the cut workpiece.

Tighten the screws; the scale is now correctly calibrated.

Always disconnect power to the machine before performing maintenance.

Failure to do this may result in serious personal injury.

Schedule

For optimum performance from your machine, follow this maintenance schedule:

Daily

• Check/correct loose mounting bolts.

• Check/correct damaged saw blade.

• Check/correct worn or damaged wires.

• Correct any other unsafe condition.

Monthly

• Check for V-belt tension, damage, or wear.

• Remove blade and thoroughly clean all builtup sawdust from the rubber tires on the wheels.

• Clean/vacuum dust buildup from inside cabinet and off motor.

Cleaning

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

Once a month, remove the blade and thoroughly clean all built-up sawdust from the rubber tires on the wheels.

-36-

SECTION 6: MAINTENANCE

Lubricating

Protect the unpainted cast iron surfaces on the table by wiping the table clean after every use— this ensures moisture from wood dust does not remain on bare metal surfaces. Keep tables rust-free with regular applications of general lubricants such as G96 ® Gun Treatment, SLIPIT ® , or

Boeshield ® T-9.

If the table becomes difficult to tilt, remove it and lubricate the trunnions and the slides in the trunnion base with a general lubricant.

Redressing Rubber

Tires

As the bandsaw ages, the rubber tires on the wheels may need to be redressed if they harden or glaze over. Redressing the rubber tires improves blade tracking and reduces vibration/blade lead.

If the rubber tires become too worn, then blade tracking will become extremely difficult. At that point, redressing will no longer be effective and the rubber tires must be replaced.

To redress the rubber tires:

DISCONNECT BANDSAW FROM POWER!

Put on heavy leather gloves.

Remove the blade.

Clean any built-up sawdust from the rubber tires.

Hold 100 grit sandpaper against the rubber tire and rotate the wheel by hand. Only redress the rubber enough to expose a fresh rubber surface.

Miscellaneous

Symptom

Blade tension scale is grossly inaccurate.

Wheel is noisy.

Blade does not track consistently, correctly, or at all.

Possible Cause

1. The spring in the blade tension mechanism has lost its "spring." This is caused by not releasing the blade tension when not in use or frequently over-tensioning the bandsaw.

1. Wheel bearing is worn out.

2. Belt is too tight (lower wheel).

Possible Solution

1. Replace spring in the blade tension mechanism, then take better care of the bandsaw by releasing tension when not in use and not over-tensioning the blade.

1. Replace the wheel bearing.

2. Check/loosen the belt tension ( Page 39 ).

1. Wheels are not coplanar or aligned with each other.

2. Rubber tires on wheels are worn out.

1. Adjust wheels to be coplanar/aligned with each other

( Page 42 ).

2. Redress the rubber tires on the wheels ( Page 36 ); replace the rubber tires on the wheels.

Servicing V-Belts

To ensure optimum power transfer from the motor to the blade, the V-belts must be in good condition and operate under proper tension. Check belt tension at least every 3 months—more often if the bandsaw is used daily. V-belts stretch with use and must be periodically re-tensioned.

Replace the V-belts if they are cracked, frayed, or excessively worn.

Accessing V-Belts

1. DISCONNECT BANDSAW FROM POWER!

2. Open the lower wheel cover.

Remove the bandsaw blade.

4. Remove the lower wheel by removing the hex bolt at the center of the wheel, then sliding the wheel off the shaft. (The hex nut has left handed threads, so you must turn it clockwise to loosen it.)

5. Take off the pulley cover plate by removing the six Phillips head screws. You now have access to the V-belts for inspection or service

(see Figure 43 ).

Shimming Table

To ensure accuracy when cutting stacked workpieces, the table should be 90˚ to the back of the blade as shown in Figure 47 . If the table is not perpendicular to the back of the blade, the table needs to be shimmed.

Shims can be made of any durable object that can be sandwiched between the table and the trunnions. We recommend using shim washers or shim stock because of the wide range of available thicknesses. These items can be purchased at your local hardware store.

Blade Lead

"Blade Lead" means that the blade does not cut straight when using the fence or miter gauge (see

Figure 48 ). This is a common condition with all bandsaws. Worn or damaged blades may cause lead and replacing them will fix the problem. Still, if your bandsaw is setup correctly and lead occurs, compensate for it by skewing the fence.

Figure 47.

Squaring table to blade back.

To shim the table:

Make sure that the blade is tracking properly and that it is correctly tensioned.

2. DISCONNECT BANDSAW FROM POWER!

Loosen the trunnion bolts that secure the trunnions to the table.

Place shim stock between the table and the two trunnions to shim the table in the desired direction.

Note: Another way to shim the table is to add washers between the table and the trunnion.

Follow the Aligning Table instructions on

Page 23 to complete this procedure.

G0621 Wood/Metal Bandsaw

Figure 48. Blade leading away from line of cut.

To correct blade lead, do the following steps and make a test cut before skewing the fence:

Ensure that you have proper blade tension

(refer to Page 19 ).

Ensure that the blade guides are adjusted correctly (refer to Pages 19 & 21 ).

Ensure that the miter slot or fence is parallel to the blade (refer to Page 23 ).

To skew your fence:

Cut a piece of scrap wood approximately 3 ⁄

" thick x 3" wide x 17" long. On a wide face of the board, draw a straight line parallel to the long edge.

Slide the fence out of the way and cut freehand along the line. Stop at the halfway point.

Turn the bandsaw OFF and wait for the blade to stop.

-41-

Clamp the board to the bandsaw table without moving it. Now slide the fence over to the board so it barely touches one end of the board.

Loosen the two cap screws that mount the front rail to the table.

Place shims between the front rail and the table as necessary to make the fence parallel to the edge of the scrap piece.

Note: Shim stock works well for this, but small pieces of paper can also work in a pinch.

To compensate for lead when making straight crosscuts with the miter gauge, you will need to shift the table:

1. Set the miter gauge to 90° and verify that the gauge body is square to the miter bar, using a 90° square.

On a scrap piece of wood, mark a line that is perpendicular to the front edge of the workpiece.

Starting where the line begins, cut the board by pushing it through the blade with the miter gauge.

Loosen the table mounting bolts, and shift the table to compensate for the blade lead.

Repeat Steps 1 & 2 until the blade cuts straight when wood is pushed through with the miter gauge.

NOTICE

If the table is shifted, the fence will be affected since it is attached.

NOTICE

Lead adjustments will change when new blades are mounted on the saw.

Wheel Alignment

Wheel alignment, or "Coplanar Tracking," is one of the easiest ways to ensure you get optimal performance from your bandsaw. When wheels are aligned, or coplanar, the bandsaw cuts straighter.

Vibration, heat, and blade wear are also considerably decreased because the blade is automatically balanced on the wheel.

Verifying Upper/Lower Wheels are

Coplanar

1. DISCONNECT BANDSAW FROM POWER!

With the blade on and properly tensioned, hold a straightedge close to the center of both wheels. Make sure the straightedge fully extends across the wheels as shown in

Figure 49 .

Figure 49.

Checking wheel alignment with a straightedge.

— If the wheels are coplanar, the straightedge wil touch the top and bottom of the outside rims on each wheel.

— If the wheels are not coplanar, place the straightedge on the lower wheel first

(ensuring that it touches both the top and bottom rim), then adjust the tracking knob to see how the upper wheel lines up with the straightedge.

-42G0621 Wood/Metal Bandsaw

— If the straightedge does not touch both wheels evenly, the upper wheel needs to be shimmed or the lower wheel needs to be adjusted.

Shimming Upper Wheel

DISCONNECT BANDSAW FROM POWER!

Adjust the tracking knob so the top wheel is parallel with the bottom wheel.

With the straightedge touching both points of the wheel that does not need to be adjusted, measure the distance away from the incorrect wheel with a fine ruler (see Figure 50 ).

The distance measured with the ruler is the distance the wheel must be corrected.

Figure 51. Coplanar diagram.

Adjusting Lower Wheel

Only do this procedure if you cannot make the wheels coplaner with the tracking knob or by shimming the upper wheel. Make sure the upper wheel is adjusted as close as possible to being coplanar with the lower wheel before beginning.

Do this procedure with the blade fully tensioned.

To adjust the lower wheel:

DISCONNECT BANDSAW FROM POWER!

Loosen the four hex bolts on the lower wheel adjustment hub ( Figure 52 ). These secure the wheel adjustment sleeves.

Hex Bolt

Wheel

Adjustment

Sleeve

Figure 50. Measuring wheel difference.

Remove the blade from the saw, then remove the wheel that needs to be shimmed.

Determine how many shim washers you need and place them on the wheel shaft.

Replace the wheel, the original washers, and the securing nut.

Tighten the blade, then check the wheels.

(Coplanar wheels may pull out of alignment when the blade is tightened.)

When the wheels are coplanar, place a mark on each wheel where you held the straightedge. This assures repeated accuracy every time you adjust your wheels.

Note: When wheels are properly coplanar, the blade may not be centered on the crown of the wheel, but it will be balanced. See

Figure 51 to better understand coplanarity.

G0621 Wood/Metal Bandsaw

Rotate the wheel adjustment sleeves to move the lower wheel as necessary to make it coplaner with the upper wheel.

Tighten the hex bolts to secure the wheel adjustment sleeves in position.
