SELECTOR LEVER
The selector lever allows the tool to be set for
various applications as listed in the following
chart, (Fig. 3).
When using demolition or chipping bits such
as bull points, chisels, spades, gouges, etc.
the "Hammer Only" mode must be selected.
SELECTOR LEVER - "VARIO-LOCK"
The vario-lock can be set in any one of twelve
positions (30˚ increments). Choose a position
which is best suited for your operation. The
Drilling/Hammering:
used for drilling with solid
carbide bits and core bits
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.
"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.

Vario-Lock position is intended for use with
chipping bits such as bull points, spades,
gouges, etc.
Depress release button and turn the selector
lever, to the "vario-lock" setting. Next, rotate
the locking sleeve, along with the accessory,
to the desired position. Then turn the
selector lever to the "hammer only" setting
and slightly turn the locking sleeve to have it
automatically lock into a definite position.
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.
