• check the correctness and clarity of operation of the switch;
• using switch 4 set the required mode of work;
• try the Electrical Rotary Hammer by idling during 5-10 seconds (also after tool change).
While working:
• periodically remove the drill from the hole to remove sludge from the drilling zone;
• watch the condition of the tool and the working tool, their heating;
• provide the ecient cooling of Electrical Rotary Hammer and the disposal of processing products from the
treatment area, do not block the ventilation holes on the housing;
• protect the Electrical Rotary Hammer from exposure of intense heat sources and chemically active substances,
as well as from the ingress of liquids and solid objects inside the housing;
• avoid mechanical damage to the Electrical Rotary Hammer (shocks, falls, etc.);
• do not overload the Electrical Rotary Hammer putting too much eort into it. For eective operation of the
impact mechanism just press the working tool to the treated surface with an eort of order 20-30 Н;
• choosing the feed force when drilling or chiseling, focus on reducing engine speed under load: decrease the
rotation more than 20% compared to idle leads to a signicant deterioration in engine cooling and indicates
overload;
• do not overheat external Electrical Rotary Hammer parts during long work. If there is an excessive heat, stop
working, let the Electrical Rotary Hammer work without load for 1-2 minutes for engine cooling, turn o the
engine and take a break until the gear housing become cool;
• do not allow the Electrical Rotary Hammer work when there is extraneous or uncharacteristic noise in the engine
or gear. When there are noises turn o the Electrical Rotary Hammer and contact an authorized service;
• turn o the Electrical Rotary Hammer with the switch before disconnecting from the power supply.
ATTENTION!
If during the usage the Electrical Rotary Hammer unexpectedly shuts down work it is necessary:
1. To turn the power key to «o» immediately and disconnect the power cable from the outlet.
2. To inspect the drill and electrical cable for damage carefully. If damage is found, contact the
service center.
3. Check for mains voltage.
4. To carry out trial switch on by turning the switch key to the “on” position for 1-2s. If in the
presence of power in the mains the Electrical Rotary Hammer does not turn on, you need to
contact the service center.
At the end of the work:
• disconnect the Electrical Rotary Hammer from the mains, making sure the switch is in the o position;
• clean the Electrical Rotary Hammer and accessories from dirt;
• with a long break in work lubricate the box with a layer of conservation grease;
• periodically clean the ventilation holes with a soft brush and vacuum cleaner.
NOISE AND VIBRATION
Noise and vibration characteristics are given in the "Specications table".
The noise and vibration levels specied in this manual are measured by measurement method, prescribed in the
standard, and can be used to compare. However, if the Electrical Rotary Hammer is used for other work with the
use of working toolings, not provided by the manufacturer, or maintenance does not meet the requirements, then
the vibration level may be dierent.
ATTENTION!
Always use personal hearing protection.
