Accessories

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

heavier the cord.

Service

NO USER SERVICE-ABLE

PARTS INSIDE. Preventive

maintenance performed by unauthorized

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. SERVICEMEN:

Disconnect tool and/or charger from power

source before servicing.

BATTERIES

Be alert for battery packs that are nearing

their end of life. Battery packs typically last

from 500 to 1000 charges. 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 re-charge better when they are

stored discharged. Remember to fully re-

charge battery packs before using after

prolonged storage.

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.

BEARINGS

Bearings which become noisy (due to heavy

load or very abrasive material cutting) should

be replaced at once to avoid overheating and

motor failure.

Cleaning

To avoid accidents, always

disconnect the tool and/or

charger from the power supply before

cleaning. The tool may be cleaned most

effectively with compressed dry air. Always

wear safety goggles when cleaning tools

with compressed air.

Ventilation openings and switch levers must

be kept clean and free of foreign matter. Do

not attempt to clean by inserting pointed

objects through opening.

Certain cleaning agents and

solvents damage plastic

parts. Some of these are: gasoline, carbon

tetrachloride, chlorinated cleaning solvents,

ammonia and household detergents that

contain ammonia.
