GENERAL MAINTENANCE
WARNING
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.
Do not allow filth to build up on the table, the guides, or
the support bearings. Clean them with gum and pitch
remover.
NOTE: Do not immerse the support bearing in the gum
and pitch remover.
Put a thin coat of paste wax on the table so that the wood
slides easily while cutting.

BLADE WHEEL TIRES
Pitch and sawdust that build up on the tires should be
removed with a stiff brush or scrape 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 then on.
MOTOR
Frequently blow or vacuum out any sawdust from the
motor. Follow lubrication instruction on the motor label.
To avoid electrocution or fire, immediately 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.
