ADJUSTMENTS

To Adjust Blade Guide Bearings:

The blade guide bearings help keep the blade from twisting and binding. The blade can be ruined if the blade teeth hit the bearings while using the band saw.

Remove the blade guard by loosening the two phillips screws.

Using a 2.5 mm hex key, loosen the two blade guide screws that lock the upper blade guide bearings. Slide the blade guide bearings to within 1/64 in. (0.4 mm) behind the gullet of the blade. Retighten the two blade guide screws securely.

Using a flathead screwdriver, turn the screw (centered in the blade guide bearing) until the bearing is within 1/64 in. (0.4 mm) of the blade. Do not pinch the blade. Make sure one guide is not further away from the blade than the other.

Repeat this procedure on the lower blade guide bearings located below the saw table. Replace the blade guard if no additional adjustments are to be made.

MAINTENANCE

WARNING:

When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage.

WARNING:

Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic 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, dust, oil, grease, etc.

WARNING:

Do not at any time let brake fluids, gasoline, petroleum- based products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury.

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:

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.

LUBRICATION

All of the bearings in this tool are lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrica- tion is required.

MOTOR/ELECTRICAL

Frequently vacuum or blow out sawdust from the motor.
