GENERAL MAINTENANCE
For your own safety, turn switch OFF and remove the plug
from power source receptacle before maintaining, cleaning,
adjusting, or lubricating your band saw.
To avoid fire or toxic reaction, never use gasoline, naphtha,
acetone, lacquer thinner or similar highly volatile solvents
to clean the band saw.
To avoid eye injury from blowing debris, wear safety
goggles when blowing out sawdust.
BAND SAW
Sawdust will accumulate under the table and base. This
could cause difficulty in the movement of the table when
setting up a band saw cut, and also cause a fire hazard.
Frequently blow out or vacuum up the sawdust.
Keep your band saw clean. Remove the sawdust from the
inside. Vacuum or blow out frequently.
NOTE': Put a thin coat of paste wax on the table so that the
wood slides easily while cutting.
Do not allow filth to build up on the table, the guides, or the
support bearings. Clean them with Craftsman Gum and
Pitch Remover.
NOTE: Do not immerse the support bearings in the gum
and pitch remover.
BLADE WHEEL TIRES
Pitch and sawdust that build up on the tires should be
removed with a stiff brush or scraped off with a piece of wood.
NOTE: To avoid damaging the tires do not use a sharp
knife or any. kind of solvent.
When the tires become worn they should be replaced.
When replacing the tires, stretch them around the wheels
but do not glue them on.
MOTOR
Frequently blow or vacuum out any sawdust from the
motor. Follow lubrication instruction on the motor label.
To avoid electrocution, or fire, i_mediatety replace a worn,
cut or damaged power cord.
LUBRICATION
All of the bearings are packed with grease at the factory.
They require no further lubrication.
CAUTION: Never put lubricants on the blade while it is
spinning.
CHANGING BELTS
t. Pull the cover knobs to open the wheel covers.
2. Loosen the idle wheel by turning the idle wheel handle.
3. Loosen the motor mount nuts and slide the motor
sideways to loosen the belt tension.
4. Remove the belt from the motor pulley and saw pulley.
NOTE: The blade wheel may need to be removed for
easy access to the pulley belt (See ADJUSTMENT
Section).
5. Place the new belt on the motor pulley and saw pulley
according to the speed desired (See OPERATION
Section).
6. Slide the motor to the side to properly tension the belt,
and tighten the motor mount nuts. Do not overtighten.
NOTE: The belt is properly tensioned if there is 1/2"
flex when the belt is pressed in the center between
pulleys.
7. Turn the idle wheel handle to press the idle wheel
against the belt.
8. Push the cover doors closed before using the band
saw.
