Service

Preventive maintenance

performed by unauthorized

per so n nel 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 Autho -

rized Bosch Service Station.

BASE CLAMP

If additional clamping force is desired: use a

2.5 mm Allen wrench and turn the set screw

clockwise SLIGHTLY (1/8 turn or less), then

test clamp. Do not over-tighten.

COLLET CHUCK CARE

With the router bit removed, continue to turn

the collet chuck counter-clockwise until it is

free of the shaft. To assure a firm grip,

occasionally blow out the collet chuck with

compressed air, and clean the taper in the

armature assembly shaft with a tissue or fine

brush. The collet chuck is made up of two

component parts as illustrated (Fig. 30); check

to see that the collet is properly seated in the

collet chuck nut and lightly thread the collet

chuck back onto the armature shaft. Replace

worn or damaged collet chucks immediately.

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 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.

Cleaning

To avoid accidents always

dis connect the tool from

the power supply before cleaning or

performing any main tenance. The tool may

be cleaned most effectively with compressed

dry air. Always wear safety gog gles when

cleaning tools with compressed air.

Ventilation openings and switch levers must

be kept clean and free of foreign matter. Do

not at tempt to clean by inserting pointed

objects through openings.

Should a significant amount of dust gather in

the motor-to-base 5V electrical connection

track on either the base or motor, the dust can

be removed with a vacuum cleaner,

compressed air or soft brush.

Certain cleaning agents

and sol vents damage

plastic parts. Some of these are: gasoline,

carbon tetrachlo ride, chlo rinated cleaning

solvents, ammonia and house hold detergents

that contain ammonia.
