OPERATION (CONTINUED)
• Avoid kickback by grinding in accordance with the directional
arrows.
• Keep your hands clear of abrasive belt and all moving parts.
• For optimum performance do not stall motor or reduce speed.
Do not force the work into the abrasive.
• Support workpiece with tool rest when grinding with belt.
• Never push a sharp corner of workpiece rapidly against belt.
Abrasive backing may tear.
• Replace abrasives when they become loaded (glazed) or frayed.
• When grinding metal, move workpiece across abrasive to pre-
vent heat build-up.
• Never attempt wet sanding. If work-piece becomes too hot to
handle, cool it in water.
BELT INSTALLATION AND TRACKING
Refer to Figure 7.
• Sanding belt should be replaced when worn, torn, or glazed.
Loosen belt cover knobs (Ref. No. 25) and open belt cover.
• Release belt tension by pulling up on tension handle Ref. No.
38). Slide old belt off the drive and tracking wheels.
• Slide new belt over the drive and tracking wheels, center belt
on wheels, and pull down on tension handle to tension belt.
• Replace belt cover and tighten knobs.
• Rotate belt by hand to check tracking, belt should ride centered
on drive and tracking wheels. Adjust socket head bolt (Ref. No.
33) at top of tracking bracket to track belt properly. Be sure to
secure socket head bolts with hex nut (Ref. No. 34).
ADJUST BELT ASSEMBLY POSITION
Refer to Figure 7.
The belt assembly can be adjusted from vertical to horizontal posi-
tion.
• Loosen the belt housing bolt (Ref. No. 9) that clamps belt hous-
ing to motor assembly.
• Tilt belt assembly to desired position (from vertical to horizon-
tal). Secure belt assembly position by tightening belt housing
bolt.
ABRASIVE BELT FINISHING
• Finishing flat surfaces: Hold workpiece firmly with both hands,
keep fingers away from abrasive belt.
Use tool rest. Tool rest is used to position and stabilize work.
Keep end butted against tool rest and move work evenly across
abrasive belt. Use extra caution when finishing very thin pieces.
For finishing long pieces: remove tool rest. Apply only enough
pressure to allow abrasive belt to remove material.
• Finishing curved edges: Finish outside curves on flat portion of
abrasive belt.
MAINTENANCE
WARNING:
Make certain that the unit is disconnected from
power source before attempting to service or remove any compo-
nent.
CLEANING
• Keep machine and workshop clean. Do not allow sawdust to
accumulate.
• Keep the wheels clean. Dirt on wheels will cause poor tracking
and belt slippage.
• Operate grinder with dust collector to keep dust from accumu-
lating.
WARNING:
After sanding wood or non-metallic 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 grinder are permanently
lubricated at the factory. They require no further lubrication.
• When operation seems stiff, a light coat of paste wax applied to
the tool rest 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.
KEEP GRINDER IN REPAIR
• If power cord is worn, cut or damaged, have it replaced imme-
diately.
• Replace worn abrasives when needed.
• Replace any damaged or missing parts. Use parts list to order
parts.
