2. Remove the brushes from the tool by
pulling on the spring that is attached to the
carbon brush. If the brush is less than 1/8"
long and the end surface of the brush that
contacts the commutator is rough and/or
pitted, they should be replaced. Check both
brushes (Figure D).
Usually the brushes will not wear out simul -
taneously. If one brush is worn out, replace
both brushes. Make sure the brushes are
installed as illus trated. The curved surface
of the brush must match the curvature of
the commutator.
3. After replacing brushes the tool should be
run at no-load; place it on a clean surface
and run it freely at full speed for 5 minutes
before loading (or using) the tool. This will
allow the brushes to “seat” properly and will
give you more hours of life from each set of
brushes. This will also extend the total life of
your tool since the com mutator surface will
“wear” longer.
BEARINGS
Models 100, 200, and 3000 have double ball
bearing construction. Under normal use they
will not require lubrication.
Cleaning
To avoid accidents
always dis connect the
tool from the power supply before cleaning
or performing any main tenance.
The tool
may be cleaned most effectively with
compressed dry air.
Always wear safety gog -
gles when cleaning tools with compressed
air.
Ventilation openings and switch levers must be
kept clean and free of foreign matter. Do not
at tempt to clean by inserting pointed objects
through openings.
Certain cleaning agents
and sol vents damage
plastic parts.
Some of these are: gasoline,
carbon tetrachlo ride, chlo rinated cleaning
solvents, ammonia and house hold detergents
that contain ammonia.

Extension Cords
If an extension cord is
necessary, a cord with
adequate size conductors that is capable
of carrying the current necessary for your
tool must be used.
This will prevent
excessive voltage drop, loss of power or
overheating. Grounded tools must use 3-wire
extension cords that have 3-prong plugs and
receptacles.
NOTE:
The smaller the gauge number, the
higher the cord capacity.
