Hold the tool with both hands and apply the

diamond wheel flat on the work surface,

advancing the tool moderately back and

forth.

When removing coatings from work

surfaces, hold the tool at a slight angle to

the workpriece surface. Holding the tool at a

slight angle will not reduce the effect of the

dust extraction.

The dry diamond cup wheel included with

the tool is intended for hard materials.

A dull dry diamond cup wheel can be

sharpened with a abrasive material (e.g.,

chalky sand stone).

Four different types of diamond grinding

wheels are available as optional accessories.

Refer to the chart for examples of their use.

Service

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.

SERVICE REMINDER LIGHT

When the service reminder light lights up or

blinks, this will indicate that the cut-out

carbon brushes will switch off the tool in

approximately 8 hours. After that period, the

light will go off and the tool will stop running.

The tool must then be sent to a service

center for service.

TOOL LUBRICATION

Your Bosch tool has been properly

lubricated and is ready to use. It is

recommended that tools with gears be

regreased with a special gear lubricant at

every brush change.

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 brushes be

examined. Only genuine Bosch replacement

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 Authorized 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.

Cleaning

To avoid accidents always

disconnect the tool from

the power supply before cleaning or

performing any maintenance. 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 openings.

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.
