Design features
of the power tool
Vibration protection system
The vibration protection system is design to reduce
vibration impact (during operation) on the operator�
Recommendations
on the power tool operation
Wear thick soft gloves when working to
reduce vibration impact on your body.
• When working, make sure to properly adjust the
working accessory to the material being processed:
not too close to the edge as the power tool will need
to be displaced often, but not too far as the accessory
can get stuck in the material being processed�
• Press the power tool while holding it tightly with both
hands� Do not use excessive force: the energy of the
percussion mechanism is enough for the effective per-
formance�
• Avoid the excessive penetration of the working ac-
cessory into the material being processed (for exam-
ple, when loosening the soil or in the course of the
building structures destruction) as the working acces-
sory may become stuck�
• If the working accessory becomes stuck in the ma-
terial during the operation, do not attempt to free it
with the use of the power tool as a lever as the power
tool can be damaged� Remove the power tool from
the jammed accessory� Continue the operation with
the use of another accessory in order to release the
jammed one� Note: it is strictly prohibited to knock
out the jammed working accessories or to swing
it and to try to extract it with the use of foreign
tools or objects (pieces of pipe, winches, jacks,
etc.).
