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 operat-
ing this product and save these instruc-
tions.
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 loca-
tions. 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 discon-
nect 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 foot-
ing and balance at all times.
14. Maintain tools with care. Keep cut-
ting 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 ac-
cessories such as blades, bits and cutters.
16. Remove adjusting keys and wrench-
es. 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

4
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 run-
ning 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 defec-
tive 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 at-
tachments recommended in this instruc-
tion manual or in the catalogue of ZENIT
ТМ.
22. Have your tool repaired by a qualied
person. This electric tool is in accordance
with the relevant safety requirements. Re-
pairs should only be carried out by quali-
ed persons using original ZENIT TM

how to use
CAUTION
This power tool is designed for domes-
tic 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.
1. Pressing force of the drill.
You cannot drill holes more quickly even
if you press the drill with a stronger force
than necessary. It not only damages tip
of drill bit and decreases the efciency of
operation, but also shortens the life of the
drill tip.
2. When a thick drill bit is used.
Your arm is subjected to larger reaction
force when a thicker drill bit is used. Be
careful not to be moved by the reaction
force. For this, establish a foothold; hold
the unit tightly with both hands perpen-
dicularly to the material being drilled.
3. Torque mechanical adjustment.
Before selecting the torque force ensure
that the switch is in «Off» position and
that the screwdriver doesn’t move. For
switching press the switch button and
adjust rotation speed by turning torque
control in the right direction.
4. Reverse function
The drill is equipped with direction
switch function.
For turning the bit clockwise switch the
rotation direction switch in the left end
position.
For turning the bit counterclockwise
switch the rotation direction switch into
the right end position.
5. Precautions right after using.
Do not put the drill with rotating bit in
place, where there is dust and chips, as
the drilling mechanism can suck them in.
CAUTION
When using the screwdriver follow these
rules:
• continuous use of the drill should not
exceed 15 minutes;
• do not allow mechanical damage
(strikes, falls etc.);
• protect the drill from external sources of
heat and chemically active substances, as
well as liquid and objects penetration;
• before disconnecting the tool from the
power source turn off the On/Off switch;
• provide effective cooling and drilling
wastes withdrawal from the tool working
zone;
• check the engine temperature, do not
allow overheating;
• change the rotation direction only after
switching off the tool and complete stop
of rotating parts.
Inobservance of these rules will make
warranty void!

Maintenance and inspection
1. Inspecting the mounting 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.
2. 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.
3. 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.
WARNING! Repair, modication
and check of ZENIT power tools should
be performed only in authorized service
centers ZENIT. While use or maintenance
of power tools follow all safety rules and
standards.
NOTE
Zenit Power Tools are constantly being
improved and modied to incorporate the
latest technological advancements.
Accordingly, some parts may be changed
without prior notice.
