MAINTENANCE
WARNING: To avoid accidents, always disconnect the tool from the power supply before cleaning or
performing any maintenance.
CLEANING
Clean the tool after every use with a soft cloth. Keep the ventilation openings free from dust and debris. Avoid us-
ing solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial
solvents and may be damaged by their use.
WARNING: Certain cleaning agents and solvents can damage plastic parts. Some of these include but
are not limited to: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and house-
hold detergents that contain ammonia.
Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear
and possible premature failure because the fiberglass chips and grindings are highly abrasive to bearings, brushes,
commutators, etc. Consequently, we do not recommended using this tool for extended work on these types of
materials. However, if you do work with any of these materials, it is extremely important to clean the tool using
compressed air after operation.
CARBON BRUSH REPLACEMENT (Fig. 12 & 13)
To maintain maximum motor efficiency, we recommend inspecting the
two carbon brushes every 60 hours of operation.
NOTE: Replacement carbon brushes (Part No. 36725-018) can be or-
dered at wenproducts.com. Only genuine WEN replacement brushes
designed specifically for your tool should be used.
1. To access the carbon brushes, unscrew and remove the motor cover
(Fig. 12). Carefully remove and examine the carbon brushes (Fig. 12 - 1).
2. The wear on the carbon brushes depends on how frequently and how
heavily the tool is used. Replace the brushes when the brush length (Fig.
13) gets down to 3/16 of an inch or when the tool sparks or stops working.
Both carbon brushes should be replaced at the same time.`
