ABRASIVE BELT FINISHING
Refer to Figure 9, page 10.
• Finishing flat surfaces: Hold workpiece firmly with both
hands; keep fingers away from abrasive belt.
Use work stop. Work stop is used to position and secure
work being sanded. Keep end butted against work stop and
move work evenly across abrasive belt. Use extra caution
when finishing very thin pieces.
Finishing long pieces: remove work stop. Apply only
enough pressure to allow abrasive belt to remove material.
Finishing curved edges: Finish outside curves on flat por-
tion of abrasive belt. Finish inside curves on idler drum por-
tion of abrasive belt.
Finishing end grain: It is more convenient to finish ends of
long workpieces with the abrasive belt in a vertical position.
Position table on belt side of sander. Lock into position with
socket head bolt and washer (Key Nos. 41 and 37). Move
work evenly across abrasive belt. For accuracy, use miter
gauge. Table may be tilted for beveled work.
REPLACING ABRASIVE DISC
• Remove disc table and dust chute. Remove old abrasive
disc by peeling it from the aluminum disc. Removing alu-
minum disc from motor shaft is not necessary.
• Clean aluminum disc if necessary. Select the proper abra-
sive disc and apply to aluminum disc.
• Additional abrasive discs are available (See Recommended
Accessories, page 11).
• Replace dust chute and disc table.
ADJUSTING DISC TABLE ANGLE
Refer to Figure 9, page 10.
Disc table is adjustable from 0 to 45 ° for beveled work.
To adjust the disc table, loosen the two handles (Key No.
36) and pivot to the desired angle.
Use the scale on disc table trunnions to set table from 0 to
45 ° from abrasive disc.
When disc table is at desired angle, lock it into position by
securely tightening the handles.
ABRASIVE DISC FINISHING
Abrasive disc sanding is well suited for finishing small flat
surfaces and convex edges
Move workpiece across down side (right) of abrasive disc.
Abrasive disc moves fastest and removes more material at
outer edge.
For accuracy, use miter gauge.
USING MITER GAUGE
Refer to Figure 9, page 10.
• The miter gauge is used on both belt and disc tables. Use
the miter gauge for securing the work and holding the prop-
er angle while sanding.
• Adjust angle by repositioning the miter gauge scale (Key
No. 78) and locking it into place with knob (Key No. 79).
• Check accuracy of miter gauge scale.
• Use a combination square to adjust miter gauge square to
disc. Indicator should be at zero. Loosen screw (Key No.
80) and reposition indicator if necessary.
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
accumulate 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 lubri-
cated at the factory. They require no further lubrication.
• When operation seems stiff, a light coat of automobile-type
wax applied to the belt table and disc table will make it eas-
ier 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.
KEEP TOOL IN REPAIR
• If power cord is worn, cut, or damaged in any way, have it
replaced 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. Repair service
is available at your nearest Sears store.
