FAILURE TO START
Should your tool fail to start, check to make sure
the prongs on the cord plug are making good
contact in the outlet. Also, check for blown fuses or
open circuit breakers in the line.
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.
T h e c a r b o n b r u s h e s f u r n i s h e d w i l l l a s t
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.
1. To inspect or replace brushes, first unplug the
machine. Carefully remove the 8 screws to
separate the two handle halves and remove
from the motor housing. Remove the left
handle half first.
2. 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.
3. Next remove the two screws holding on the
Electronics Unit to allow access to the Brush
Holder screws. Hold the Electronics Unit off to
one side and avoid stressing the wires.
4. Unscrew the two Carbon Brush Holders in
turn 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. Replace the
Brush Holder screws, then the Electronics Unit
screws. When Replacing the rear handle to the
motor housing, take great care that all wires are in
place and not in a position to be pinched when it is
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.
