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.
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

4
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, break-
age 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 man-
ual 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. 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.

TECHNICAL SPECIFICATIONS
Model GM-350
Rated power 350 W
Rated voltage 220-240 V
Rated frequency 50-60 Hz
No load speed 11000 rpm
Grinding surface 90x187 mm
APPLICATIONS
The machine is intended for dry sanding of wood, plastic, ller and coated surfaces.
PRIOR TO OPERATION
1. Power source.
Ensure that the power source to be utilized conforms to the power
source requirements specied on the product nameplate.
2. Power switch.
Ensure that the power switch is in the OFF position. If the plug is con-
nected to a receptacle while the switch is in the ON position, the power
tool will start operating immediately and can cause serious injury.
3. Extension cord.
When the work area is far away from the power source, use an exten-
sion cord of sufcient thickness and rated capacity. The extension cord
should be kept as short as practicable.
4. Installing the sanding paper.
• Bending the sanding paper:
Position the sander with its pad side facing upward. Place the sanding
paper on the pad so that the center of the sanding paper is aligned with
the center of the pad, and bend both ends of the sanding paper at a 90°
angle. Then bend both ends again. The sanding paper is now ready to be
installed
• Installing the sanding paper.
While ensuring that the cord is not bent, place the sander on a work-
bench and insert one end of the sanding paper (bent section). Next insert
the remaining bent section in the same manner.

Attention
The sanding paper must be precisely installed on the pad, ensuring that
there is no ample tension (leaving no slack). Loosely installed sanding
paper could result in unevenly sanded surfaces and/or damage to the
sanding paper itself.
5. Attaching and removing the dust bag
• Attaching
Hold the dust gate of the bag and attach it to the dust outlet on the
sander.
• Removing
Hold the dust gate of the bag remove lter from dust outlet of the
sander.
SANDER OPERATION
Never apply water or grinding uid when sanding. This could result in electrical
shock.
1. Switching the sander ON and OFF
The power can be turned on by setting the lever to ON and turned off by setting the
lever to OFF.
WARNING
Never turn the power switch ON when the sander is contacting the surface to be
sanded. This is necessary to preclude damage to the material. The same applies when
switching the power OFF.
2. How to hold the nishing sander
While gripping the housing, lightly press the sander against the surface to be sanded
so that the sanding paper uniformly contacts the surface. DO NOT apply excessive
pressure to the sander while sanding. Excessive pressure may cause overload of the
motor, reduced service life of the sanding paper, and lowered sanding or polishing
efciency.
3. How to move the nishing sander.
For optimum operating efciency, alternately move the sander forward and backward
at a constant speed and balance.
4. After installing a new sanding sheet.
Sander can move unsmooth after installing a new sanding paper because its surface is

7
rougher. This can be avoided by subtle movement of the sander back and forth when
grinding or polishing. Sander movement will become smoother as the paper will wear
out.
MAINTENANCE AND INSPECTION
1. Emptying and cleaning the dust bag
If the dust bag contains too much saw dust, dust collection will be affected. Empty the
dust bag when it gets full. Remove the dust bag, open the fastener, and dispose of the
contents.
2. Inspecting the sanding paper
If the dust bag contains too much saw dust, dust collection will be affected. Empty the
dust bag when it gets full. Remove the dust bag, open the fastener, and dispose of the
contents.
3. Inspecting the screws
Regularly inspect all screws and ensure that they are fully tightened. Should any of the
screws be loosened, retighten them immediately.
4. 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. Maintenance
In case of malfunction of power tool consult an authorized technical service agent.
CAUTION
When using the screwdriver follow these rules:
• continuous use of the power tool should not exceed 15 minutes;
• do not allow mechanical damage (strikes, falls etc.);
• protect the power tools from external sources of heat and chemically active substanc-
es, as well as liquid and objects penetration;
• 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.
Inobservance of these rules will make warranty void!
