MAINTENANCE
PRE-ASSEMBLY CHECK
WARNING: For your own safety, switch “OFF” and remove plug from power source
before adjusting, maintaining, or lubricating your belt and disc sander.
WARNING: To avoid electrocution or fire, any repairs to electrical systems should be
done only by qualified service technicians. The unit must be reassembled exactly to
factory specifications.
If the mains lead is worn or cut, or damaged in any way, have it replaced immediately.
Frequently blow out or vacuum any dust that may accumulate inside the motor.
A coat of wax applied to the worktable will make it easier to feed the work while finishing.
Do not apply wax to the abrasive belt table because the belt could pick up the wax and
deposit it on the pulleys, causing the belt to slip.
Lubrication
The BALL BEARINGS in this machine are packed with grease at the factory. They require
no further lubrication. Sleeve bearings should be lubricated with 30 weight oil or equivalent
after each 10 hours of operation.
Removing Pulley Cover And Installing Drive Belt
1. Using a cross head screwdriver,
remove the screw located in the
middle of the cover.
2. Remove the cover.
3. Loosen (3) screws to allow pulleys
to move enough to place the belt
around them. Place belt around
the motor pulley and drive pulley as
shown.
Separate all parts from packing materials and check each item with the “Table of
Loose Parts.” Make certain all items are accounted for, before discarding any packing
material.
WARNING: If any parts are missing, do not attempt to assemble the Belt and Disc
Sander, plug in the mains lead, or switch until the missing parts are obtained and
