Operating Instructions

ROCKER “ON/OFF” SWITCH

TO TURN THE TOOL "ON" depress the dust-protected switch to the number “I” position.

TO TURN THE TOOL "OFF": depress switch to the number “0” position (Fig. 1).

For low temperatures, the machine reaches the full impact rate only after a certain time.

This start-up time can be shortened by striking the chisel in the tool against the floor one time.

 

"VARIO-LOCK"- SELECTOR RING

 

The vario-lock selector ring can be set in any

 

one of twelve (30˚ increments) positions.

 

Choose a position which is best suited for your

 

operation. To adjust, pull the selector ring

 

forward and hold firmly, then turn both the

 

accessory and the selector ring to the desired

 

position. Release the selector ring and turn

 

the accessory slightly until it locks in place

 

(Fig. 6).

VARIAbLE SPEED DIAL

Your tool is equipped with a variable speed dial. The speed and impact force can be adjusted by rotating the dial. Higher speeds

and impact force work best for faster penetration when chiseling in hard masonry material. Slower speeds work best for chiseling material such as plaster or tile (Fig. 7).

CONSTANT RESPONSE CIRCUITRy

The internal electronic feedback system provides a "soft start", which will reduce the stresses that occur from a high torque start. The system also helps to keep the pre- selected impact rate virtually constant between no-load and load conditions.

VIbRATION DAMPER HANDLE /

HAMMER MECHANISM

The integrated vibration damper in the main handle and hammer mechanism reduces vibrations (Fig. 7).

Tool Tips

For the best penetration rates in concrete, run the tool with a steady pressure, but do not use excessive force as this will decrease the efficiency of the tool.

All hammers require a short period of time to warm up. Depending on the room temperature, this time may vary from approximately 15 seconds (90˚F) to 2 minutes (32˚F). A new hammer requires a break-in period before full performance is realized. This period may

require up to 5 hours of operation.

An electric hammer is likely to be the most expensive portable tool at the construction job. The long wear and efficient operation of the BOSCH hammers will more than justify the cost for tools of this type. As earlier pointed out, sharp accessories as well as clean air vents are necessary for efficient operation. Establish and follow a set maintenance program.
