AUXILIARY HANDLE
Tighten the auxiliary handle 1 on the journal 2 of
the rotary hammer. In the interests of safety, the
auxiliary handle 1 should always be used. The
depth gauge 5 can be used for fixing the depth
of the drilled bores.
TORQUE LIMITATION
The safety clutch limits the torque. Upon actu-
ating the safety clutch stops the spindle rota-
tion and the tool (drill bit) ceases to rotate. In
this case switch the machine off immediately to
avoid premature wear.
RECOMENDATIONS fOR OPERATION
Apply moderate pressure during drilling in con-
crete (approximately 80-100 N). Higher pres-
sure will not increase drilling efficiency, but it
will result in 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 blunting of the bit and
change it if considerable decrease of efficiency
is observed.
Do not operate the machine in «Hammer drill-
ing» and «Hammer» mode with the lever 7 in
rightmost position.
Depending on the processed material it is possi-
ble that the impact energy may decrease during
operation in «Hammer» mode (chiselling and
demolishing and in «Hammer drilling» mode. To
restore the maximum impact energy it is neces-
sary to reduce the revolutions by decreasing the
pressure on the switch trigger 9 until the advent
of stable impact.
Before drilling large-diameter holes in metal,
first drill a small pilot hole.
The optimum capacity for drilling in concrete
with twist drill bits is shown in the table with tech-
nical specifications.
The rotary hammer is suitable for light-duty chis-
elling. Higher durability and efficiency can be
achieved only when using sharp chisels.

Maintenance

WARNING: Always ensure that the
tool is switched off and unplugged before
attempting to perform inspection or mainte-
nance.
Original instructions
GENERAL INSPECTION
Regularly inspect all fasteners and ensure they
are properly tightened. Should any of the screws
be loose, retighten it immediately to avoid haz-
ards.
If the replacement of the supply cord is neces-
sary, this has to be done by the manufacturer or
his agent in order to avoid a safety hazard.
CLEANING
For safe operation always keep the machine
and its ventilation slots clean.
Regularly check to see if any dust or foreign
matter has entered the ventilation slots and the
grills around the switches. Use a soft brush and/
or air jet to remove any accumulated dust. Wear
safety glasses to protect your eyes whilst clean-
ing.
Exterior plastic parts may be cleaned with a
damp cloth and mild detergent if necessary.
WARNING: Never use alcohol, petrol
or other cleaning agent. Never use caustic
agents to clean plastic parts.
WARNING: Water must never come
into contact with the tool.
IMPORTANT! To assure product safety and re-
liability, repairs, maintenance and adjustment
(including brush inspection and replacement)
should be performed by certified service centres
or other qualified service organisations, always
using genuine replacement parts.
