MAINTENANC
To avoid possible injury or damage, NEVER use this band
saw to cut ferrous metals.
CAUTION: When cutting nonferrous metals, metal shavings
can react with wood dust and start a fire. To avoid this:
1. Disconnect any dust collecting hose from the band
saw.
2. Remove all trades of wood dust from inside the saw.
3. Remove all metal shavings from inside the saw
before sawing wood again.
GENERAL MAINTENANCE
A 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 Craftsman Gum and Pitch
Remover.
NOTE: Do not immerse the support bearings in the gum and
pitch remover.
Put a thin coat of paste wax on the table so that the wood
slides easily while cutting.
