WIRE BRUSHES
Work with brushes requires high speeds.
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.
CORRECT: Wire tips doing the work.
15°
INCORRECT: Excessive pressure can cause wire breakage.
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.
RUNNING NUTS AND BOLTS
Variable speed control must be used with caution for driving nuts and bolts with socket set attachments. The technique is to start slowly, increasing speed as the nut or bolt runs down. Set the nut or bolt snugly by slowing the drill to a stop. If this procedure is not followed, the tool will have a tendency to torque or twist in your hands when the nut or bolt seats.
Maintenance
Service
!WARNING NO USER SERVICEABLE PARTS INSIDE, except for
the replaceable carbon brushes. Preventive maintenance performed by unauthorized personnel may result in misplacing of internal wires and components which could cause serious hazard. We recommend that all tool service be performed by a Bosch Factory Service Center or Authorized Bosch Service Station. SERVICEMEN: Disconnect tool and/or charger from power source before servicing.
BATTERIES
Be alert for battery packs that are nearing their end of life. If you notice decreased tool performance or significantly shorter running time between charges then it is time to replace the battery pack. Failure to do so can cause the tool to operate improperly or damage the charger.
Long term battery storage should be in the discharged state. Battery packs last longer and
TOOL LUBRICATION
Your Bosch tool has been properly lubricated and is ready for use.
D.C. MOTORS
The motor in your tool has been engineered for many hours of dependable service. To maintain peak efficiency of the motor, we recommend it be examined every six months. Only a genuine Bosch replacement motor specially designed for your tool should be used.
CARBON BRUSHES
The brushes and commutator in your tool have been engineered for many hours of dependable service.
If your tool runs sporadically, loses power, makes unusual noises or runs at a reduced speed, check the brushes. To continue using the tool in this condition will permanently damage your tool.
Check both brushes. Usually the brushes will not wear out simultaneously. If one brush is worn out, replace both brushes.
