ADDITIONAL HINTS FOR USING ROTARY HAMMER
Impact drilling and chiselling requires slight pressing on the rotary hammer.
To achieve the best efficiency possible during operation, apply uniform and moderate (not excessive) pres-
sure on the tool, as excessive pressure would lead to efficiency loss and overloading the motor. Rotary ham-
mer 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.
OPERATION AND MAINTENANCE
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.
