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.
AUXILIARY HANDLE
The tool must be supported with the
auxiliary handle, which can be swiveled 360˚.
To reposition and/or swivel the handle,
loosen the hand grip, move the handle to the
desired position along the barrel and
securely retighten the hand grip.
DEPTH GAUGE
Your drilling depth can be pre-set and/or
repeated by using the depth gauge.
Setting depth: After the auxiliary handle is
installed, slide the depth gauge to desired
depth and securely tighten wing knob.
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 grease packed 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.
A rotary 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.
