SLIP CLUTCH

The tool has a internal pre-set slip clutch. The output spindle will stop rotating if the accessory binds and overloads the tool.

TOOL TIPS

Following a few simple tips will reduce wear on the tool and the chance of injury to the operator.

The high efficiency available from the BOSCH Rotary Hammer can only be obtained if sharp and undamaged drilling tools are used. Note that the costs for maintaining sharp drilling tools are more than offset by the time lost in operating dull drilling tools.

All grease packed hammers require a short time to warm up. Depending on the

temperature, this time will vary from approximately 15 seconds (90° F) to 2 minutes (32° F). The tool will exert its full power and hammering action after the heat from impact hammering has spread, softening the grease.

CARbIDE TIPPED bITS

The rotary hammer is designed to use SDS- Max® carbide tipped bits for drilling into stone, concrete, cement, brick, cinder block, mortar, soft stone and other unusually hard non-metal materials.

The amount of pressure to be used is dependent upon the type of material being drilled. Soft materials require less pressure; while hard materials require more pressure.
