GENERAL SAFETY PRECAUTIONS
WARNING! When using electric
tools, basic safety precautions should
always be followed to reduce the risk of
re, electric shock and personal injury,
including the following.
Read all these instructions before
operating this product and save these
instructions.
For safe operations:
1. Keep work area clean. Cluttered areas
and benches invite injuries.
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.
9. Use eye protection. Also use face or
dust mask if the cutting operation is
dusty.
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.
17. Avoid unintentional starting. Do not
carry a plugged in tool with a nger on
the switch. Ensure switch is off when
plugging in.

18. Use outdoor extension leads. When
tool is used outdoors, use only extension
cords intended for outdoor use.
19. Stay alert. Watch what you are doing.
Use common sense. Do not operate tool
when you are tired.
20. Check damaged parts. Before further
use of the tool, a guard or other part that
is damaged should be carefully checked
to determine that it will operate properly
and perform its intended function.
Check for alignment of moving parts,
free running of moving parts, breakage
of parts, mounting and any other
conditions that may affect its operation.
A guard or other part that is damaged
should be properly repaired or replaced
by an authorized service center unless
otherwise indicated in this instruction
manual. Have defective switches replaced
by an authorized service center. Do not
use the tool if the switch does not turn it
on and off.
21. Warning Use only accessories
or attachments recommended in this
instruction manual or in the catalogue of
ZENIT ТМ.
Have your tool repaired by a qualied
person. This electric tool is in accordance
with the relevant safety requirements.
Repairs should only be carried out by
qualied persons using original ZENIT
TM spare parts. Otherwise this may result
in considerable danger to the user.

INTENDED USE
Demolishing concrete, chiseling concrete,
grooving, bar cutting, and driving piles.
Installation of piping and wiring, sanitary
facility installation, machinery installa-
tion, water supply and drainage work,
interior jobs, harbor facilities, and other
engineering works.
1. Power source.
Ensure that the power source to be uti-
lized 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 posi-
tion, the power tool will start operating
immediately, inviting serious accident.
3. Extension cord.
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. УREPLACING THE TOOL.
Clean and grease the tool shank. Install
the tool shank into hexagonal hole on the
front cover.
Clamp the tool.
HOW TO USE
1. After placing the tip of the tool
on concrete surface, switch ON.
In some cases, it is necessary to thrust the
tip of the bit against the crushing posi-
tion forcibly in order to begin the striking
motion.
2. By utilizing the empty weight
of the machine and by rmly holding
the hammer by both hands, you can ef-
fectively control the subsequent recoil
motion. Proceed at a moderate work-rate,
the use of too much pushing force will
impair efciency.
HOW TO REPLACE GREASE
Please contact the nearest service center
ZENIT for grease replacement.
MAINTENANCE AND INSPECTION
1. INSPECTING THE TOOLS.
Since use of a dull tool will cause motor
malfunctioning and degraded efciency,
replace the tool with a new one or re-
sharpen without delay when abrasion is
noted.
2. Inspecting the screws
Regularly inspect all mounting screws
and ensure that they are properly tight-
ened. 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 mo-
tor 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.
CAUTION
When using the drill follow these rules:

6
• 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!
