3. GENERAL SAFETY INSTRUCTIONS

          WARNING! 

Read all safety warnings and all instructions. Failure to follow the warnings and 

instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference. The term “power tool” in the warnings refers 
to your mainsoperated (corded) power tool or battery-operated (cordless) power tool.

1.WORK AREA SAFETY

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable 
liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to 
lose control.

2.ELECTRICAL SAFETY

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter 
plugs with earthed (grounded) power tools.Unmodified plugs and matching outlets will reduce risk 
of electric shock.
• Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and 
refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions.Water entering a power tool will increase the 
risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep 
cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the 
risk of electric shock.
• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a 
cord suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is unavoidable, use an earth leakage circuit breaker. 
Use of an earth leakage circuit breaker reduces the risk of electric shock.

3.PERSONAL SAFETY

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not 
use a power tool while you are tired or under the influence of drugs, alcohol or medication. A 
moment of inattention while operating power tools may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as 

dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions 
will reduce personal injuries.
• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power 
source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on 
the switch or energising power tools that have the switch on invites accidents.
• Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left 
attached to a rotating part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the 
power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away 
from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities, ensure these 
are connected and properly used. Use of dust collection can reduce dust-related hazards.

4. POWER TOOL USE AND CARE

• Do not force the power tool. Use the correct power tool for your application. The correct power 
tool will do the job better and safer at the rate for which it was designed.
• Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be 
controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/or the battery pack from the power tool before 
making any adjustments, changing accessories, or storing power tools. Such preventive safety 
measures reduce the risk of starting the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the 
power tool or these instructions to operate the power tool. Power tools are dangerous in the hands 
of untrained users.
• Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and 
any other condition that may affect the power tool's operation. If damaged, have the power tool 
repaired before use. Many accidents are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are 
less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc., in accordance with these instructions, taking 
into account the working conditions and the work to be performed. Use of the power tool for opera-
tions different from those intended could result in a hazardous situation.

5.SERVICE

> Have your power tool serviced by a qualified repair person using only identical replacement parts. 
This will ensure that the safety of the power tool is maintained.

4. SAFETY INSTRUCTIONS FOR POLISHERS

1. SAFETY INSTRUCTIONS FOR ALL OPERATIONS

a) This power tool is intended to function as a polisher. Read all safety warnings, instructions,illus-
trations and specifications provided with this power tool. Failure to follow all instructions listed 
below may result in electric shock, fire and/or serious injury.
b) This power tool is not recommended for grinding,sanding, wire brushing or cutting off opera-
tions.Operations for which the power tool was not designed may create a hazard and cause perso-
nal injury.
c) Do not use accessories which are not specifically designed and recommended by the tool manu-
facturer. Just because the accessory can be attached to your power tool, it does not assure safe 

operation.
d) The rated speed of the accessory must be at least equal to the maximum speed marked on the 
power tool. Accessories running faster than their rated speed can fly apart.
e) The outside diameter and the thickness of your accessory must be within the capacity rating of 
your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
f) The arbour size of wheels, flanges, backing pads or any other accessory must properly fit the 
spindle of the power tool. Accessories with arbour holes that do not match the mounting hardware 
of the power tool will run out of balance, vibrate excessively and may cause loss of control.
g) Do not use a damaged accessory. Before each use inspect the accessory such as abrasive 
wheels for chips and cracks, backing pads for cracks, tear or excess wear, wire brushes for loose or 
cracked wires. If the power tool or accessory is dropped, inspect for damage or install an undama-
ged accessory. After inspecting and installing an accessory, position yourself and bystanders away 
from the plane of the rotating accessory and run the power tool at maximum no load speed for one 
minute. Damaged accessories will normally break apart during this test time.
h) Wear personal protective equipment .Depending on application, use face shield, safety goggles 
or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and shop apron 
capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of 
stopping flying debris generated by various operations. The dust mask or respirator must be capa-
ble of filtrating particles generated by your operation. Prolonged exposure to high intensity noise 
may cause hearing loss.
i) Keep bystanders a safe distance away from work area. Anyone entering the work area must wear 
personal protective equipment. Fragments of the workpiece or of a broken accessory may fly away 
and cause injury beyond the immediate area of operation.
j) Hold power tool by insulated gripping surfaces only, when performing an operation where the 
cutting accessory may contact hidden wiring or its own cord. A cutting accessory contacting a 
"live" wire may make exposed metal parts of the power tool "live" and could give the operator an 
electric shock.
k) Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or 
snagged and your hand or arm may be pulled into the spinning accessory.
l ) Never lay the power tool down until the accessory has come to a complete stop. The spinning 
accessory may grab the surface and pull the power tool out of your control.
m) Do not run the power tool while carrying it at your side. Accidental contact with the spinning 
accessory could snag your clothing, pulling the accessory into your body.
n) Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing 
and excessive accumulation of powdered metal may cause electrical hazards.
o) Do not operate the power tool near flammable materials. Sparks could ignite these materials.
p) Do not use accessories that require liquid coolants. Using water or other liquid coolants may 
result in electrocution or shock.

2) KICKBACK AND RELATED WARNINGS

• Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any 
other accessory.Pinching or snagging causes rapid stalling of the rotating accessory which in turn 
causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation 
at the point of the binding.
• For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel 
that is entering into the pinch point can dig into the surface of the material causing the wheel to 
climb out or kick out. The wheel may either jump toward or away from the operator, depending on 
the direction of the wheel’s movement at the point of pinching. Abrasive wheels may also break 
under these conditions.

• Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions 
and can be avoided by taking proper precautions as given below.
a) Maintain a firm grip on the power tool and position your body and arm to allow you to resist 
kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or 
torque reaction during start-up. The operator can control torque reactions or kickback forces, if 
proper precautions are taken.
b) Never place your hand near the rotating accessory. The accessory may kickback over your hand.
c) Do not position your body in the area where power tool will move if kickback occurs. Kickback 
will propel the tool in the direction opposite to the wheel’s movement at the point of snagging.
d) Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the 
accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and 
cause loss of control or kickback.
e) Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent 
kickback and loss of control.

5. GENERAL

• This tool should not be used by people under the age of 16 years
• This tool is not intended for use by persons (including children) with reduced physical, sensory or 
mental capabilities, or lack of experience and knowledge, unless they have been given supervision 
or instruction concerning use of the tool by a person responsible for their safety
• Ensure that children do not play with the tool
• This tool is not suitable for wet sanding
• Always disconnect plug from power source before making any adjustment or changing any

6. BEFORE USE

• Before using the tool for the first time, it is recommended to receive practical information.
• Always check that the supply voltage is the same as the voltage indicated on the nameplate of the 
tool (tools with a rating of 230V or 240V can also be connected to a 220V supply).
• Use suitable detectors to find hidden utility lines or call the local utility company for assistance(-
contact with electric lines can lead to fire or electrical shock; damaging a gas line can result in an 
explosion; penetrating a water pipe will cause property damage or an electrical shock).
• Do not work materials containing asbestos (asbestos is considered carcinogenic).
• Dust from material such as paint containing lead, some wood species, minerals and metal may be 
harmful (contact with or inhalation of the dust may cause allergic reactions and/or respiratory 
diseases to the operator or bystanders); wear a dust mask and work with a dust extraction device 
when connectable.
• Certain kinds of dust are classified as carcinogenic (such as oak and beech dust) especially in 
conjunction with additives for wood conditioning; wear a dust mask and work with a dust extraction 
device when connectable.
• Follow the dust-related national requirements for the materials you want to work with.
• Do not clamp the tool in a vice.
• Use completely unrolled and safe extension cords with a capacity of 16 Amps (U.K. 13 Amps).

7. AFTER USE

• Fold the front and back part together (2a).
• Push the folding lock D to the right position and keep the tip adjacent to the handle .(2b)
• Press the folding lock D towards the handle until the end. (2c) Unfold the handle by pushing the 
folding lock to the inside.

Replace sanding pad 

③

• Insert the hex wrench R (size 5) into the hexagonal screw bolt on the sanding block.
• Hold the sanding pad firmly, and then turn the wrench counter clockwise to dismount the pad.
• Install new sanding pad by tightening the bolt.

          WARNNING:

 Only install the specified sanding pad on the machine. In order to ensure optimal 

performance, the machine should be run at slightly lower speed for several minutes to make the 
grinding pad fit the sealing surface perfectly. During this process, the white foam particles will come 
out from the sanding head. However, this won't damage the machine.

Attaching and changing sanding disc 

③

• Place the sanding disc in the center of the sanding pad and press on. The holes in the sanding 
disc must be in alignment with the extraction holes in the sanding pad.
• For round sanding pad only: conduct a test run to check that the sanding disc is clamped in the 
centre.

Extension shaft(optional) 

④

• use the extension shaft (O) according to the intended operation for higher work surface
• loosen the sleeve on the dust extraction outlet (N) of the upper shaft (F).do not remove the sleeve 
from the outlet.
• align the rear handle (O1) with the main handle (E) and insert the sleeve (O3) on the extension 
shaft (O) into the outlet (N) with a twist motion all the way to the stop.
• adjust the length of the extension shaft (O) if necessary.pay attention to the marking “max 1.65m” 
on the extension shaft.tighten the sleeve (N) after assembling/adjusting the extension shaft.

Dust suction 

⑤

• Loosen locking knob for length adjustment N by turning it in the direction of the unlocking symbol 
on the tool handle.
• Insert Vacuum hose P into the end of the tool handle as illustrated.
• Tighten Locking knob for length adjustment N by turning it in the direction of the locking symbol 
on the tool handle.
• Connect the Vacuum hose with the Ø 47 mm adapter P4 directly to an industrial vacuum cleaner 
(remove vacuum cleaner hose first).
• One may also connect vacuum hose with one of the 3 adapters to an industrial vacuum cleaner 
without removing the vacuum cleaner hose.

Tool standard/airflow control 

⑧

• Tool handle P1 prevents the hose from damage when putting the tool aside during
work breaks.
• Control the airflow by sliding suction power adjustment ring P3 over the opening in

tool connector P2.
• The vacuuming power is at its lowest level when the opening is fully visible.

Switching the machine on and off

• Turn on/off the drywall sander by switch G Electronic speed control
• Adjust the speed by turning the speed wheel M, user can choose different speed for different 
sanding surface.
• Constant speed control Keep the machine running at the same speed as selected.
Do not overload by excessive pressure.

8. SANDING OPERATIONS

Once the machine and vacuum cleaner are set up and all safety measures and equipment are in 
place, begin by turning on the vacuum cleaner and then the machine. (If you are using a vacuum 
cleaner with integrated switching, then simply turn the machine on.)

Round sanding head 

⑥

• Begin sanding and carefully contact the work surface as lightly as possible-just enough to keep 
the sanding head flat against the surface.
• The pivot point in the sanding head allow the sanding disc to follow the contours of the work  
surface.
• The best technique is to use overlapping sweeps and keep the head in constant motion. Never 
stop too long in any one place or there will be swirl marks. With experience it will be very easy to 
create excellent results.

          Ensure that the sanding disc you are using is suited to the task, Overly coarse grit paper may 
remove material too quickly to control. While overly fine grit paper may clog too often and not shape 
down the surface.

          Take care to avoid sharp projections and nails, etc. This will wipe out the sandpaper and 
probably damage the sponge pad as well.

9. MAINTENANCE / SERVICE

• Store the tool in its protective case in a dry and lockedup place, out of reach of children.
• Always keep tool and cord clean (especially ventilation slots ) 

          Do not attempt to clean ventilation slots by inserting pointed objects through openings
          Disconnect the plug before cleaning.

10. ENVIRONMENT

Do not dispose of electric tools, accessories and packaging together with household waste material 
(only for EU countries).
• In observance of European Directive on waste of electric and electronic equipment and its imple-
mentation in accordance with national law, electric tools that have reached the end of their life must 
be collected separately and returned to an environmentally compatible recycling facility
