Basic Operations (continued)
Recommended Cutting Capacity
WARNING:
Use of tool for
greater than recommended capaci-
ties may lead to motor burn-out and
possible electric shock.
NOTE:
Cutting through any cross section
of material thicker than 1/2” tends to load
up the abrasive wheel, and this will cause
your tool to work harder.
Maintenance and Lubrication
Maintenance
WARNING:
This cut-off machine
is only designed for dry cutting.
Failure to heed this warning could
result in serious personal injury.
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 accumulated
dust from working parts.
Make sure that the tool operates properly.
Periodically check screws and bolts for tight-
ness.
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 procedure. 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 over-
tighten.
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 perfor-
mance 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 lubrica-
tion.
WARNING:
To ensure safety
and reliability, all repairs, with the
exception of externally accessible
brushes, should be performed at an
Authorized Service Center. Use
only RIDGID replacement parts.
