MAINTENANCE
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.

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.
