turn the tool slightly by hand left wise and right
wise until it is locked.
(1) Impact drilling – for drilling masonry, con-
crete, etc.
(2) Changing the chisel position to fix the chisel
in the desired angular position for demolition and
chiselling (see "Changing the chisel position").
(3) Hammer mode – for chiselling and de-
molition.
WARNING: Turn the operation mode
selector switch only in the direction marked
on the switch.
INSERTING Of SDS-MAx TOOL
Clean and grease the shank of the accessory,
before placing it into the socket!
Keep the locking socket 2 in upper (front) posi-
tion while inserting the tool.
Place the tool into the spindle without effort.
Rotate the tool until the grooves coincide.
After the grooves have coincided, push the tool
down (until the fixing mechanism produces an
audible "click"). Check the proper fixing of the
tool by pulling it strongly outwards.
WARNING:
chisels switch 6 shall always be in "hammer"
position.
REMOVING THE SDS-MAx TOOL
Pull the locking clutch entirely back and take the
tool out.
CHANGING THE CHISEL POSITION
- Insert the tool in the socket as it is described
in point "Inserting the SDS-max tool".
- Turn the operating mode switch 6 in position
"Changing the chisel position".
- Turn the tool by hand to the desired position.
- Turn the operating mode switch 6 in position
"hammer", and then turn the tool slightly by hand
left wise and right wise until it is locked.
Longer operation life of the rotary hammer and
higher efficiency can be achieved only with well-
sharpened tools for demolition and chiselling.
AUxILIARY HANDLE
Always use the auxiliary handle.
Loosen the handle by turning it left wise. Turn
the handle in the most convenient for operation
position, and then tighten it well.

For operating with
Do not carry the machine by a loose auxiliary
handle.
You can fix the drilling depth through depth
gauge 4. The depth gauge 4 can be fixed by
screw 3.
The auxiliary handle for these models is con-
nected to the body of the machine through vi-
bration dampers, protecting the operator and
reducing fatigue.
RECOMMENDATIONS fOR
OPERATION
Apply moderate pressure during operation (ap-
proximately 100-150 N)! Higher pressure will not
increase efficiency when drilling and chiselling,
but it will lead to decreasing the operation life of
the machine.
Take the drill bit out of the opening from time to
time to remove dust.
Watch out for the stage of bit blunting and re-
place the bit when considerable decrease of ef-
ficiency is observed.
