Your tool is also equipped with a “Lock-ON”

button located on the left side of the trigger

handle that allows for operation at maximum

RPM without holding the trigger (Fig. 1).

TO LOCK TRIGGER "ON": squeeze trigger,

depress button and release trigger.

TO UNLOCK THE TRIGGER: squeeze trigger

and release it without depressing the "Lock-

ON" button.

To increase switch life, do not

turn switch on and off while

tool is under load.

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. 1).

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.

1. Turn selector switch to the

vario-lock position.

2. Insert accessory into the tool holder, then

turn the accessory to the desired position.

3. Turn selector switch to the

hammer position, then turn

accessory until it engages.

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.
