B: Hammer drilling into cement,
stonework and brickwork (Fig. 6)
C: Chiseling without rotation function in
brickwork or for removing tiles (Fig. 7).
CAUTION! Never operate the tool
with the rotation function active
and a chase bit inserted!
The required hammer action for
hammer drilling in stone is generated
by a pneumatic hammer. This electro
pneumatic principle creates a high blow
elasticity and ensures backlash free
operation. Unlike other types of hammer
drill, the drilling performance is not
dependant on the pressure.
CAUTION! A greater pressure,
thus, does not increase the
performance!
Working above your head
When carrying out work above your
head, fit the dust collector (14) to the
drill in accordance with Figure 5.
Speed preselection (Fig. 10)
In order to protect the
materials you are working
on, use the speed
recommendations made by
the accessory manufacturer. Set the
speed using the wheel for speed
preselection (4):
• Turn the wheel (4) to position 6 =
Highest speed possible
• Turn the wheel (4) to position 1 =
Lowest speed possible
10 – Maintenance and
environmental
protection
CAUTION! Unplug from the
power source.
Use only a damp cloth to clean the
power tool housing. Do not use
solvents! Then dry off carefully! Always
keep the power tool air vents clean and
free of obstructions. Ensure that the
gear system is adequately lubricated.
After approx. 5 hours operating time
unscrew the sealing cap (2) with the
flange key and check whether sufficient
grease can be seen.
CAUTION! Electrical and battery
operated units that no longer work
should not be disposed of in the
household waste! They are to be
collected separately, in accordance
with the 2012/19/EU
directive for the disposal
of electrical and
electronic waste, and sent
for proper and environ
mentallyfriendly
recycling.
Please discard power tools no longer
usable at a local collection point.
Collection and disposal of packaging
