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 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. 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.
Using pliers, rotate the brush spring out of the way and slide old carbon brush out of the brush
holder.
Unplug the spade connector to remove the brush lead. The old carbon brush many now be lifted
away.
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.
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
