Maintenance

Service

!WARNING NO USER SERVICEABLE 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. 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.

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.

DRIVE BELT

The drive belt is a normal maintenance part and should be inspected periodically for wear. If the drive belt shows signs of drying out, cracking or tearing, it should be replaced. If the drive belt will not track properly or comes off the pulleys, it should be replaced.

Installing new drive belt: Loosen screws and remove the drive belt cover (Fig. 9). Cut and remove the worn drive belt. Before installing the new drive belt, clean both pulleys thoroughly. First place the new drive belt onto the drive pulley then rotate clockwise while pushing the belt onto the driven pulley. Reinstall the drive belt cover and securely tighten screws (Fig. 10).
