Turn the power switch “OFF”
and unplug the power cord from its power source
prior to any maintenance or repairs.
LUBRICATION
The buffer has sealed lubricated bearings in the
motor housing that do not require any additional
lubrication from the operator.
CLEANING
Periodically blow areas in and around the buffer
to keep the machine and work area clean. Should
the buffing wheels become glazed with excessive
compound or metallic build-up, clean the wheel
with a metal buffing rake or stiff wire brush.
CAUTION:
REPLACE the buffing wheels if there
is any damage at all.
FAILURE
to replace a
damaged wheel can cause serious injury to the
operator. Periodically check all nuts and fasten
-
ers to make sure that they are secure. Check the
power cord, plug and switch and replace them if
they are found to be worn.
CAUTION: DO NOT USE FLAMMABLE
MATERIALS
to clean the Buffer. A clean dry rag
or brush is all that is needed to remove dust and
debris buildup.
Repairs to the Buffer
should be performed by trained personnel only.
Unauthorized repairs or replacement with non-
factory parts could cause serious injury to the
operator and damage to the machine.
