Slight run out of the working tool that can be sometimes observed after starting the tool without
load is normal. Working tool centres automatically at touching processed material. In no way it
affects precision of drilling.
ADDITIONAL HINTS FOR USING ROTARY HAMMER
Impact drilling requires slight pressing on the rotary hammer.
To achieve the best efficiency possible during operation, apply uniform and moderate (not excessive)
pressure on the tool, as excessive pressure would lead to efficiency loss and overloading the motor.
Rotary hammer filled with solid lubricant requires some time to heat up, depending on the surrounding
temperature. If the rotary hammer is not used for a long time, or operates in low temperature, allow the
rotary hammer to work with no load for 2-3 minutes. Sharp working tools improve work efficiency. Clean
ventilation holes reduce risk of motor overheating.
Unplug the power cord from mains socket before commencing any activities related to installation,
adjustment, repair or maintenance.
MAINTENANCE AND STORING
● Cleaning the device after each use is recommended.
● Do not use water or any other liquid for cleaning.
● Do not use any cleaning agents or solvents, they may damage plastic parts.
● Clean the tool with a dry cloth or blow with compressed air at low pressure.
● Clean ventilation holes in the motor casing regularly to prevent device overheating.
● In case of excessive commutator sparking, have the technical condition of carbon brushes of the motor
checked by a qualified person.
● In case of power cord damage replace it with a cord with the same specification. Entrust the repair to a
qualified specialist or return the tool to a service point.
● Always store the tool in a dry place, beyond reach of children.
REPLACEMENT OF CARBON BRUSHES
Immediately replace worn out (shorter than 5 mm), burnt or cracked motor carbon brushes. Always
replace both carbon brushes at a time.
Entrust replacement of carbon brushes only to a qualified person. Only original parts should be
used.
All defects should be repaired by service workshop authorized by the manufacturer.
