ADJUSTMENTS

To Adjust Blade Guides:

The blade guides help keep the blade from twisting and binding. The blade will be ruined if the blade teeth hit the blade guides while using the band saw. The set of teeth and the sharpened edge of teeth will be damaged by hitting the blade guides. Proper adjustment of the upper and lower blade guides will prevent this from happening.

￿Remove the blade guard by loosening the two phillips screws.

￿Loosen the two blade guide support screws that lock the upper blade guides. Slide the two guides to within 1/32 in. (0.8 mm) of the blade. Do not pinch the blade. Make sure one guide is not further away from the blade than the other. Retighten the two blade guide support screws securely.

￿Replace the blade guard if no additional adjustments are to be made.

￿Repeat this procedure on the lower blade guides located under the saw table. See Figure 21.

MAINTENANCE

WARNING:

To ensure safety and reliability, all repairs should be performed by an authorized service center.

GENERAL MAINTENANCE

Avoid using solvents when cleaning parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, carbon dust, etc.

WARNING:

Do not, at any time, let brake fluids, gasoline, petroleum- based products, penetrating oils, etc., come in contact with plastic parts. They contain chemicals that can damage, weaken or destroy plastic.

￿Keep your band saw clean.

￿Remove sawdust from the inside frequently.

￿Do not allow pitch to accumulate on the saw table, blade guides, or thrust bearings. Clean them with gum and pitch remover.

￿Apply a thin coat of automobile type wax to the saw table’s top so the wood slides easily while cutting.

WARNING:

If the power cord is worn, cut or damaged in any way, have it replaced immediately by a qualified service technician. Failure to do so could result in serious personal injury.

WARNING:

To avoid fire or electrocution, reassemble electric parts with only identical replacement parts. Reassemble exactly as originally assembled.

TIRES

Cleaning tires:

￿Pitch and sawdust accumulates on tires and needs to be removed with a fine wire brush or a piece of wood. Do not use a sharp knife or any kind of solvent.

Replacing tires:

￿Open front cover and remove saw blade. See section on Installing and Adjusting the Blade, page 17.

￿Pry the worn tire away from the wheel carefully.

￿Stretch the new tire around the wheel.

￿Replace the saw blade and close the front cover.

WARNING:

To prevent accidental starting that could cause possible serious personal injury, turn off the saw, remove the switch key, and unplug the saw before working on the band saw.

MOTOR/ELECTRICAL

￿Frequently vacuum or blow out sawdust from the motor.

BLADE GUIDES

See Figure 22.

￿Blade guides may become rounded and worn during use. Remove the blade guides and file or grind flat.
