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:

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.

BLADE GUIDES

See Figure 22.

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

Replace blade guides when filing or grinding has worn them down and they can no longer be properly secured in place.
