GENERAL SAFETY PRECAUTIONS
WARNING! When using electric tools, basic safety precautions should always be fol-
lowed 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 exten-
sion 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.

Safety precautions on using jig saw
This Jig Saw employs a high-power motor. If the machine is used continuously at low speed,
an extra load is applied to the motor which can result in motor seizure. Always operate the
power tool so that the blade is not caught by the workpiece during operation. Always adjust the
blade speed to enable smooth cutting..

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.
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. Dust
Dust created by power sawing can cause damage to health. One of the following ways
is recommended:
а) using dust mask
б) using dust suction equipment.
When using suction equipment connect adaptor with hose of the dust suction equip-
ment.
5. Changing blades

6
5.1 Open the lever up to the stop.
5.2 Remove tted blade
5.3 Insert new blade up to the stop in the blade holder
5.4 Close the lever
CAUTION!
Be sure to switch power OFF and disconnect the plug from the receptacle when chang-
ing blades.
Do not open the lever when plunger is moving.
NOTE!
Conrm the protrusion of blade inserted to the blade holder surely. Conrm the blade
located between the groove of roller.
6. Adjusting the blade operating speed
The jig saw is equipped with the electric control circuit which enables stepless speed
control. To adjust the speed, turn the dial. When the dial is set to “1”, the jig saw oper-
ates at the minimum speed (500 /min.). When the dial set to “5”, the jig saw operates at
the maximum speed (3000/min.). Adjust the speed according to the material to be cut
and working efciency.
7. Cutting stainless steel plates
This Jig Saw can cut stainless steel plates by using No. 97 blade. Carefully read “Con-
cerning cutting of stainless steel plates” for proper operation.
8. Splinter guard
Using the splinter guard when cutting wood materials will reduce splintering of cut
surfaces.
Insert the splinter guard in the space on the base, and push it completely.
9. Chip cover
Chip cover prevents chips from ying off and improves the efciency of dust collector.
Insert the chip cover between the base and lever, and push with a slight pressure until it
catches in place. When removing chip cover, hold both sides of knob and slightly open
until it can be removed from the Jig Saw
NOTE! There is a possibility that chip cover is frosted when cutting the metal.
10. Sub base
Using the sub base (made from steel) will reduce abrasion of aluminum base especially
in cutting metals.
Using the sub base (made from rasin) will reduce scratching of surface. Attach the sub
base to the bottom surface of base by attached 4 screws.

CUTTING
CAUTION!
In order to prevent blade dislodging, damage or excessive wear on the plunger, please
make sure to have surface attached to the work piece while sawing.
1. Rectilinear cutting
When cutting on a straight line, rst draw a marking gauge line and advance the saw
along that line. Using the guide (sold separately) will make it possible to cut accu-
rately on a straight line.
(1) Loosen the base bolt allen wrench attached on base.
(2) Move the base fully forward, and tighten the base bolt again.
(3) Attach the guide by passing it through the attachment hole on the base and tighten
the M5 bolt.
(4) Set the orbital position to “0”.
2. Cutting a circle or a circular arc
The guide also will be helpful for circular cutting. After attaching the guide by same
way noted as above, drive the nail or screw into the material through the hole on the
guide, then use it for a axis when cutting.
NOTE: Circular cutting must be done with the blade approximately vertical to
the bottom surface of the base.
4. Cutting metallic materials
(1) Adjust the speed Dial between scales “3” and “4”.
(2) Set the orbital position to “0” or “I”.
(3) Always use an appropriate cutting uid (spindle oil, soapy water, etc.). When a
liquid cutting uid is not avaiable, apply grease to the back surface of the material to
be cut.
5. Pocket cutting
(1) In lumber
Aligning the blade direction with the grain of the wood, cut step by step until a win-
dow hole is cut in the center of the lumber.
(2) In other materials
When cutting a window hole in materials other than lumber, initially bore a hole with
a drill or similar tool from which to start cutting.
6. Angular cutting
The base can be swiveled to both sides by up to 45° for angular cutting.
(1) Loosen the base bolt by allen wrench attached on base and move the base fully
forward.
(2) Align the scale (from 0 degrees to 45 degrees by 15-degree increments) of the
semi-circular part of the base with the [ ] mark on the gear cover.
(3) Tighten the M5 bolt again.
(4) Set the orbital position to “0”.

8
NOTE: Angular cutting cannot be done when adopting chip cover or dust
collector.
CONNECTING WITH CLEANER
By connecting with cleaner (sold separately) through dust collector and adopter (sold
separately), most of dust can be collected.
(1) Remove the allen wrench from the base.
(2) Move the base fully forward.
(3) Attach the chip cover with the shutter put between the chip cover and gear cover.
(4) Connect the dust collector with adopter.
(5) Connect the adapter with the nose of cleaner.
(6) Insert dust collector into the rear hole of the base until the hook catches in the
notch.
(7) Press the hook to remove the dust collector.
NOTE!
Wear dust mask when possible.
SELECTION OF BLADES
To ensure maximum operating efciency and results, it is very important to select the
appropriate blade best suited to the type and thickness of the material to be cut.
HOUSING THE ALLEN WRENCH
It is possible to house the auxiliary wrench on the base.
MAINTENANCE AND INSPECTION
1. Inspecting the blade
3. Since use of a dull tool will cause motor malfunctioning and degraded efciency,
replace the drill bit with a new one or resharpening without delay when abrasion is
noted.
4. 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.
5. 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.
6. Inspecting the carbon brushes.
The motor is equipped with carbon brushes, which wear with time. When a brush

9
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.
7. Replacing power cord
In case power cord of the tool is damaged, contact ZENIT authorized service center to
replace it.
CAUTION
When using the drill follow these rules:
• continuous use of the tool 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!
