Maintenance and Lubrication

Maintenance

WARNING: Do not use any type
of cutting lubricant with this tool.
WARNING: To reduce the risk of
injury from unexpected starting
or electrical shock, unplug the
power cord before working on
the machine.
Keep the tool clean. Remove accumu-
lated dust from working parts.
Make sure that the tool operates properly.
Periodically check screws and bolts for
tightness.
Feed oil at the oiling points once a month
for extending machine service life
(machine oil is suitable for the tool).
Oiling points
• Rotary part of shaft
• Rotary part of vise
• Slide way of vise
Replacing Carbon Brushes
The carbon brushes furnished will last
approximately 50 hours of running time or
10,000 on/off cycles. Replace both carbon
brushes when either has less than 1/4"
length of carbon remaining. To inspect or

replace brushes, first unplug the machine.
Then remove the black plastic cap on the
side of the motor (caution, this cap is
spring loaded by the brush assembly).
Then pull out the brush. Repeat for the
other side. To reassemble reverse the pro-
cedure. The ears on the metal end of the
brush assembly go in the same hole the
carbon part fits into. Tighten the cap
snugly but do not overtighten.
NOTE: To reinstall the same brushes, first
make sure the brushes go back in the way
they came out. Otherwise a break-in
period will occur that will reduce motor
performance and increase brush wear.
It is recommended that, at least once a
year, you take the tool to an Authorized
Service Center for a thorough cleaning
and lubrication.
WARNING: To ensure safety and
reliability, all repairs, with the
exception of externally accessi-
ble brushes, should be per-
formed at an Authorized Service
Center. Use only RIDGID replace-
ment parts.
