SERVICEABLE PARTS
INSIDE. Preventive maintenance
performed by un au thorized personnel may
result in misplacing of internal wires and
components which could cause serious
hazard.
We recom mend that all tool service
be performed by a Bosch Factory Service
Center or Authorized Bosch Service Station.
SERVICE MEN: Disconnect tool and/or
charger from power source before servicing.
TOOL LUBRICATION
Your Bosch tool has been properly lubricated
and is ready for use.
CARBON BRUSHES
The brushes and commutator in your tool have
been engineered for many hours of dependable
service. To maintain peak efficiency of the
motor, we recommend every two to six months
the brush es be examined. Only genuine Bosch
replace ment brushes specially designed for
your tool should be used.
BEARINGS
After about 300-400 hours of operation, or at
every second brush change, the bearings
should be replaced at Bosch Factory Service
Center or Au thorized Bosch Service Station.
Bearings which become noisy (due to heavy
load or very abrasive material cut ting) should
be replaced at once to avoid overheating or
motor failure.
Maintenance
Wire brushes are intended to “clean” structural
steel, castings, sheet metal, stone and
concrete. They are used to remove rust, scale
and paint.
Avoid bouncing and
snagging the wire brush,
especially when working corners, sharp edges
etc. This can cause loss of control and kick-
back.
BRUSHING PRESSURE
1. Remember, the tips of a wire brush do the
work. Operate the brush with the lightest
pressure so only the tips of the wire come
in contact with the work.
2. If heavier pressures are used, the wires
will be overstressed, resulting in a wiping
action; and if this is continued, the life of
the brush will be shortened due to wire
fatigue.
3. Apply the brush to the work in such a way
that as much of the brush face as possible
is in full contact with the work. Applying the
side or edge of the brush to the work will
result in wire breakage and shortened brush
life.
