ABRASIVE DISC FINISHING
•
Abrasive disc sanding is well suited for finishing small flat
surfaces and convex edges.
•
Move workpiece across down side (left) of abrasive disc.
•
Abrasive disc moves fastest and removes more material at outer
edge.
•
For accuracy, use miter gauge.
REPLACING ABRASIVE DISC
1. Loosen and remove four bolts from disc cover plate.
2. Loosen two top bolts from dust collection port.
3. Remove disc cover plate.
4. Remove old abrasive by peeling it from the cast iron disc. Re-
moving cast iron disc is not necessary.

and apply to cast iron disc.
•

MAINTENANCE
WARNING:
Make certain that the unit is disconnected from power
source before attempting to service or remove any component.
CLEANING
Keep machine and workshop clean. Do not allow sawdust to accu-
mulate on the tool. Keep the drums clean. Dirt on drums will cause
poor tracking and belt slippage. Operate tool with dust collector to
keep dust from accumulating.
WARNING:
After sanding wood or nonmetallic material, always
clean dust collector and guards of sawdust before grinding metal.
Sparks could ignite debris and cause a fire.
•
Be certain motor is kept clean and is frequently vacuumed free
of dust.
•
Use soap and water to clean painted parts, rubber parts and
plastic guards.
LUBRICATION
The shielded ball bearings in this tool are permanently lubricated
at the factory. They require no further lubrication.
•
When operation seems stiff, a light coat of paste wax applied to
the belt and disc tables 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 the drums causing belt to slip.
KEEP TOOL IN REPAIR
•
If power cord is worn, cut, or damaged in any way, have it re-
placed immediately.
•
Replace worn abrasives when needed.
•
Replace any damaged or missing parts. Use parts list to order
parts.
Any attempt to repair motor may create a hazard unless repair is
done by a qualified service technician.
