Adaptive Speed Control

mode, the power tool starts
at a low idle speed for better

positioning. When force is
applied to the workpiece, the speed
quickly increases.

is damaged (Fig. 1).
Kickback Control
The rapid shut-off feature
enables better control and
improves user’s comfort. The
power tool automatically shuts
off in case of sudden and
unexpected rotation of the power tool
around the drilling axis (for example
jamming of the drill bit in reinforcing steel
or wedging application tool). To restart
the power tool, release the trigger switch
and then actuate again.
Kickack Control can activate only when
the power tool is running at maximum
operating speed and can rotate freely
around the drill bit axis.
Tool Tips
F o r t h e b e s t p e n e t r a t i o n r a t e s i n
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 /
32°C) to 2 minutes (32°F / 0°C). A new
h a m m e r r e q u i r e s a b r e a k - i n p e r i o d
before full performance is realized. This
period may require up to 5 hours of
operation.
A combination hammer is likely to be
the most expensive portable tool at the
construction job. The long wear and
e f f i c i e n t o p e r a t i o n o f t h e B O S C H
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.
