Maintenance
Warning:
When servicing use only identical Ryobi replace-
ment parts. Use of any other parts may create a hazard or
cause product damage.
Warning: To avoid serious personal injury make sure the
belt/disc sander is turned OFF and the cord is unplugged
from the power source before performing any maintenance
or adjustment.
General maintenance
After using your belt/disc sander, clean it completely and
lubricate all sliding and moving parts. Apply a light coat of
automotive type paste wax to the worktable to help keep
the surfaces clean.
Motor housing
Frequently blow out any dust that may accumulate inside
the motor housing.

in the center of the pulley cover.

pulley releases the belt tension.

there is about 1/4 in. (6 mm) of give.
• Tighten the belt tension nut securely.

creased noise and overload the motor. Excessive looseness
on the drive belt may cause the drive belt to fail prema-
turely and make a severe chattering noise.

cover and the two phillips head screws. Tighten secure-
ly.
