MAINTENANCE

WARNING:
When servicing, use only identical RIDGID
replacement parts. Use of any other part may create
a hazard or cause product damage.
WARNING:
Always wear safety goggles or safety glasses with
side shields during power tool operation or when
blowing dust. If operation is dusty, also wear a
dust mask.
GENERAL
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
a clean cloth to remove dirt, carbon dust, etc.
CAUTION:
Do not at any time let brake fluids, gasoline, petro-
leum-based products, penetrating oils, etc. come in
contact with plastic parts. They contain chemicals
that can damage, weaken or destroy plastic.

amount of high grade lubricant for the life of the unit under
®

tion is required.

BRUSH REPLACEMENT

See Figure 15, page 21.
The cut-off machine has externally accessible brush
assemblies that should be periodically checked for wear.
Proceed as follows when replacement is required:
 Unplug the cut-off machine.
 Remove brush cap with a screwdriver. Brush assembly is
spring loaded and will pop out when you remove brush cap.
 Remove brush assembly.
 Check for wear. Replace both brushes when either has
less than 1/4 in. length of carbon remaining. Do not
replace one side without replacing the other.
 Reassemble using new brush assemblies. Make sure
curvature of brush matches curvature of motor and that
brush moves freely in brush tube.
 Make sure brush cap is oriented correctly (straight) and
replace.
 Tighten brush cap securely. Do not overtighten.
