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
