Maintenance and Lubrication
Maintenance
WARNING: Do not use any type of cutting lubricant
with this tool.
WARNING: To reduce the risk of injury from unex-
pected 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 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"
Lubrication
All the motor bearings in this tool are lubricated with a
sufficient amount of high grade lubricant for the life of the
unit under normal operating conditions, therefore, no fur-
ther lubrication is required (see below).
Infrequent Lubrication as Required:
Chop pivot: Light machine oil or aerosol will penetrate
from ends and junction points. Qualified service techni-
cian can remove pivot upstop to relieve spring tension in
Basic Cutter Requirements
• 14" Diameter
• Abrasive cut-off wheels marked for 3600 RPM or
higher.
• 1" Diameter Arbor Hole
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 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 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 lubrication.
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.
order to drive shaft about 3/4" right. Exposed surfaces
are lubricated with automotive type oil
Central pivot of guard: Use light household oil (sewing
machine oil) on metal-to-metal guard contact areas as
required for smooth, quiet operation. Reduce the Risk of
excess oil, to which cutting debris will cling and a fire haz-
ard from sparks could be caused.
