Carbon Brushes - stayer MULTI DRILL 130 Manual De Instrucciones

CARBON BRUSHES

The brushes and commutator in your tool have been
engineered for many hours of dependable service.
In order to prepare your brushes for use, run your tool at full
speed for 5 minutes under no load. This will properly "seat"
your brushes, which extends the life of both your brushes
and your tool.
To maintain peak efficiency of the motor, we recommend
every 40 - 50 hours the brush es be examined. Only original
replacement brushes specially designed for your tool
should be used.
MAINTENANCE OF REPLACEABLE BRUSHES
The brushes should be inspected frequently when tools are
used continuously. If your tool runs spo rad ically, loses
power, makes unusual noises or runs at a reduced speed,
check the brushes.
To continue using the tool in this condition

Follow these steps to check/change the rotary tool brushes:
1. With the power cord unplugged, place the tool on a clean
surface. Use the tool wrench as a screwdriver to remove the
brush caps in a counter-clockwise direction.
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.

CURVED END OF BRUSH MUST
MATCH CURVATURE OF HOUSING
Usually the brushes will not wear out simultaneously. 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.
