on wheels will cause poor tracking and belt slippage.
Operate tool with dust collector to keep dust from accu-
mulating.
WARNING: After sanding wood or nonmetallic materi-
al, always clean area of sawdust before grinding metal.
Sparks could ignite debris and cause a fire.
Be certain motor is kept clean and is frequently vacu-
umed free of dust.
Use soap and water to clean painted parts, rubber
parts and plastic guards.
LUBRICATION
The shielded ball bearings in this sander are perma-
nently lubricated at the factory. They require no further
lubrication.
• When operation seems stiff, a light coat of automo-
bile-type wax applied to the belt table and disc table
will make it easier to feed the work while finishing.
• Do not apply wax to the belt platen. Belt could pick
up wax and deposit it on wheels causing belt to slip.
