6) MAINTENANCE
Every 50 hours of operation blow compressed air
through the motor while running at no load to clean
out accumulated dust. (If operating in especially
dusty conditions, perform this operation more
often.)
KEEP TOOL CLEAN
Periodically blow out all air passages with dry
compressed air. All plastic parts should be cleaned
with a soft damp cloth. NEVER use solvents to clean
plastic parts. They could possibly dissolve or
otherwise damage the material. Wear safety
glasses while using compressed air.
THE CARBON BRUSHES
The carbon brushes are a normal wearing part and
must be replaced when they reach their wear limit.
NOTE: Checking and replacing the carbon brushes
should be entrusted to a qualified service center.
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 and lay it
on its side. To inspect or replace brushes, first
unplug the machine. Carefully remove the 4 screws
to separate the rear handle halves and then remove
the 4 screws which connect the handle to the motor
housing. Lift away the left-hand handle half first.
There will still be wires connected to the rear
handle, so take care that these are not stressed.
Simply hold the rear handle off to one side. Next
remove the two screws holding on the Electronics
Unit to allow access to the Brush screws. Hold the
Electronics Unit off to one side and avoid stressing
the wires. Rotate the spiral spring to relieve the
tension on the brush and slide it out of the holder.
Unscrew the two screws which hold the brush leads
and remove the Carbon Brushes.
NOTE: When putting the Carbon Brushes back into
the Carbon Brush Holders it is essential that both
flanges go back inside the holder.
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.
Replacing is the reverse of removal. When Replacing
all covers, take great care that all wires are in place
and not in a position to be pinched when they are
retightened. It is recommended that, at least once a
year, you take the tool to an Authorized Service
Center for a thorough cleaning and lubrication.
If the replacement of the power supply cord is
necessary, this has to be done by the
manufacturer or their agent in order to avoid a
safety hazard.
WARNING: All repairs must be entrusted to an
authorized service center. Incorrectly performed
repairs could lead to injury or death.
