MAINTENANCE
WARNING: To avoid accidents, turn OFF and unplug the tool from the electrical outlet before cleaning,
adjusting, or performing any maintenance work.
WARNING: Any attempt to repair or replace electrical parts on this tool may be hazardous. Servicing
of the tool must be performed by a qualified technician. When servicing, use only identical WEN replacement
parts. Use of other parts may be hazardous or induce product failure.
CARBON BRUSH REPLACEMENT
The wear on the carbon brushes depends on how frequently and how
heavily the tool is used. To maintain maximum efficiency of the motor,
we recommend inspecting the two carbon brushes every 60 hours of
operation or when the tool stops working.
NOTE: Replacement carbon brushes (Part No. 48107-022) can be
ordered at wenproducts.com. Only genuine WEN replacement brushes
designed specifically for your tool should be used.
1. To access the carbon brushes, remove the carbon brush covers (Fig.
1) on the left and right side of the motor housing.
2. Carefully remove the carbon brushes using pliers. Keep track of which
orientation the old carbon brushes were in to prevent needless wear if
they will be reinstalled.
3. Measure the length of the brushes (See Fig. 2 to see which portion
to measure). Replace the brushes if either carbon brush length is worn
down to 3/16 of an inch. Both carbon brushes should be replaced at the
same time.
4. Install the carbon brushes and the carbon brush covers.
NOTE: New carbon brushes tend to spark for a few minutes during the
first use as they wear down.
