2. Consider work area environment. Do not expose power tools to rain. Do not use
power tools in damp or wet locations. Keep work area well lit. Do not use power tools
where there is risk to cause re or explosion.
3. Guard against electric shock. Avoid body contact with earthed or grounded surfaces.
(e.g. pipes, radiators, ranges, refrigerators).
4. Keep children and inrm persons away. Do not let visitors touch the tool or extension
cord. All visitors should be kept away from work area.
5. Store idle tools. When not in use, tools should be stored in a dry, high or locked up
place, out of reach of children and inrm persons.
6. Do not force the tool. It will do the job better and safer at the rate for which it was
intended.
7. Use the right tool. Do not force small tools or attachments to do the job of a heavy
duty tool. Do not use tools for purposes not intended.
8. Dress properly. Do not wear loose clothing or jewelry; they can be caught in moving
parts. Rubber gloves and non-skid footwear are recommended when working outdoors.
Wear protecting hair covering to contain long hair.

10. Connect dust extraction equipment. If devices are provided for the connection of
dust extraction and collection facilities ensure these are connected and properly used.
11. Do not abuse the cord. Never carry the tool by the cord or yank it to disconnect it
from the receptacle. Keep the cord away from heat, oil and sharp edges.
12. Secure work. Use clamps or a vise to hold the work. It is safer than using your hand
and it frees both hands to operate tool.
13. Do not overreach. Keep proper footing and balance at all times.
14. Maintain tools with care. Keep cutting tools sharp and clean for better and safer
performance. Follow instructions for lubrication and changing accessories. Inspect tool
cords periodically and if damaged, have it repaired by authorized service center. Inspect
extension cords periodically and replace, if damaged. Keep handles dry, clean, and free
from oil and grease.
15. Disconnect tools. When not in use, before servicing, and when changing accessories
such as blades, bits and cutters.
16. Remove adjusting keys and wrenches. Form the habit of checking to see that keys
and adjusting wrenches are removed from the tool before turning it on.

PRIOR TO OPERATION
1. Power source.
Ensure that the power source to be utilized conforms to the power requirements speci-
ed on the product nameplate.
2. «On\Off» switch.
Ensure that the power switch is in the OFF position. If
the plug is connected to a receptacle while the power switch is in the ON position, the
power tool will start operating immediately, inviting serious accident.
3. Extension cord.

6
When the work area is removed from the power source. Use an extension cord of
sufcient thickness and rated capacity. The extension cord should be kept as short as
practicable.
4. Replacing the bit.
Insert the bit into the chuck and x it with the wrench or turn the upper part of the
keyless chuck.
5. Selecting the appropriate drill bit.
When boring concrete or stone use a concrete drill bit.
When boring metal or plastic use an ordinary metalworking drill bit.
When boring wood use an ordinary woodworking drill bit.
WARNING: Do not use the Impact Drill in the IMPACT function if the
material can be bored by rotation only. Such action will not only reduce drill efcien-
cy, but may also damage the drill tip. Operating the Impact Drill with the change lever
in mid-position may result in damage. When switching, make sure that you shift the
change lever to the correct position.
6. Fixing the side handle.
Attach the side handle to the mounting part. Rotate the side handle grip in a clockwise
direction to secure it.
Set the side handle to a position that is suited to the operation and then securely
tighten the side handle grip.
HOW TO USE
1. Intended use
CAUTION
This power tool is designed for domestic use and is not intended for industrial
purposes. In case of using the power tool for industrial or professional purposes, the
manufacturer disclaims the product warranty liabilities.
CAUTION
To prevent accidents, make sure to turn the switch off and disconnect the plug from
the receptacle when the drill bits and other various parts are installed or removed. The
power switch should also be turned off during a work break and after work.
2. Rotation + Hammering
This rotary hammer can be set to rotation and hammering mode by pressing the push
button and turning the change lever:
• Mount the drill bit.
• Pull the trigger switch after applying the drill bit tip to the drilling position.
• Pushing the rotary hammer forcibly is not necessary at all. Pushing slightly
so that drill dust comes out gradually is just sufcient.
Caution

7
When the drill bit touches an iron reinforcing rod, the bit will stop immediately and
the rotary hammer will react to revolve. Therefore please grip the side handle and
handle tightly as shown in Fig. 8.
3. Rotation only
This rotary hammer can be set to
rotation only mode by pressing the
push button and turning the change
lever to mark.
To drill a wood or metal material using
the separately sold drill chuck and chuck
adaptor, proceed as follows. Installing
drill chuck and chuck adaptor:
• Attach the drill chuck to the chuck adaptor.
• The part of the SDS-plus shank is the same as the drill bit.
CAUTION.
Application of force more than necessary will not only reducing drilling efciency at
all, but will deteriorate the tip edge of the drill bit and reduce the service life of the
rotary hammer in addition.
Do not attempt to drill anchor holes or holes in concrete with the main unit in the rota-
tion only function.
Do not attempt to use the rotary hammer in the rotation and striking function with the
drill chuck and chuck adaptor attached. This would seriously shorten the service life of
every components of the machine.
CAUTION
When using the drill follow these rules:
• continuous use of the drill should not exceed 15 minutes;
• do not allow mechanic damage (strikes, falls etc.);
• protect the drill from external sources of heat and chemically active substances, as
well as liquid and objects penetration;
• provide effective cooling and drilling wastes withdrawal from the tool working zone;
• before disconnecting the tool from the power source turn off the On/Off switch;
• check the engine temperature, do not allow overheating;
• change the rotation direction only after switching off the tool and complete stop of
rotating parts;
• do not use bits not intended for concrete and brick drilling in impact mode.
Inobservance of these rules will make warranty void!

Maintenance and inspection
1. Inspecting the drill bits.
Since use of an abraded drill bits will cause motor malfunctioning and degraded
efciency, replace the drill bits with a new one or resharpening without delay when
abrasion is noted.
2. Inspecting the mounting screws.
Regularly inspect all mounting screws and ensure that they are properly tightened.
Should any of the screws be loose, retighten them immediately. Failure to do so could
result in serious hazard.
3. Maintenance of the motor.
The motor unit winding is the very “heart” of the power tool. Exercise due care to
ensure the winding does not become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes.
The motor is equipped with carbon brushes, which wear with time. When a brush
reaches the wear limit, the motor may malfunction. If the engine is equipped with
a disengaging brush, it will automatically turn off. In this case replace both carbon
brushes. Keep the brushes clean and ensure that brushes move freely within the brush
holders.
