Motor
Excessive dust in motor could cause excessive heat in
motor.
Every effort should be made to prevent foreign material
from entering the motor. When operated under conditions
likely to permit accumulations of dust, dirt or waste within
the motor, a visual inspection should be made at frequent
intervals. Accumulations of dry dust can usually be blown
out successfully.
NOTE: Motors used on wood working tools are particu-
larly susceptible to the accumulation of sawdust and
wood chips and should be blown out or “vacuumed” fre-
quently to prevent interference with normal motor ventila-
tion.
To remove dust, blow off motor with a low pressure air
hose.
CAUTION: To reduce the risk of eye injury or
adverse reaction to dust, high air pressure should
not be used, especially in poorly ventilated areas.
The operator performing this cleaning function should
wear safety goggles and filter mask.
Do not use unit if power cord becomes worn or frayed.
If any servicing (other than the above cleaning) becomes
necessary, it should be performed by an Authorized
RIDGID Service Center.
NOTE: The speed of this motor cannot be regulated or
changed.
Troubleshooting
WARNING: For your own protection, turn switch “OFF” and always remove plug from power source outlet
before troubleshooting.
