General power tool safety warnings
Warning: Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in electric
shock, fire and/or serious injur y.
Save all warnings and instructions for future reference.
The term "power tool" in the warnings refers to your mains-
operated (corded) power tool or battery-operated (cordless) power
tool.
1. Work area safety
a
Keep work area clean and well lit. Cluttered or dark areas invite
accidents.
b
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.
c
Keep children and bystanders away while operating a power
tool. Distractions can cause you to lose control.
2. Electrical safety
a
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.
b
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.
c
Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
d
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.
e
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.
f
If operating a power tool in a damp location is unavoidable, use
a residual current device (RCD) protected supply. Use of an RCD
reduces the risk of electric shock.
3. Personal safety
a
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 injur y.
b
Use personal protective equipment. Always wear eye
Page 4
4
protection. Protective equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c
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.
d
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.
e
Do not overreach. Keep proper footing and balance at all
times. This enables better control of the power tool in unexpected
situations.
f
Dress properly. Do not wear loose clothing or jewellery. Keep
your hair, clothing and gloves away from moving parts. Loose
clothes, jewellery or long hair can be caught in moving parts.
g
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
a
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.
b
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.
c
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.
d
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.
e
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.
f
Keep cutting tools sharp and clean. Properly maintained cutting
tools with sharp cutting edges are less likely to bind and are easier
to control.
g
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
Page 5
5
tool for operations different from those intended could result in a
hazardous situation.
5. Service
a
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.
b
If the replacement of the supply cord is necessary, this has to be
done by the manufacturer or his agent in order to avoid a safety
hazard.
Additional safety instructions for
your sander
Harmful/toxic dusts will arise from sanding e.g. lead painted
1
surfaces, woods and metals. Contact with or inhalation of these
dusts can endanger the health of operator and bystanders. Always
use eye glasses and dust mask.
Hearing protection should be worn when using the sander.
2
Always wear safety glasses or eye shields when using the
3
sander. Everyday eyeglasses have only impact-resistant
lenses; they are not safety glasses. Following this rule will
reduce the risk of serious personal injury.
Remove the plug from the socket before carrying out any
4
adjustment, servicing or maintenance.
Fully unwind cable drum extensions to avoid potential overheating.
5
When an extension cable is required you must ensure it has the
6
correct ampere rating for your power tool and is in a safe electrical
condition.
Ensure your mains supply voltage is same as indicated on the
7
rating plate.

Warning: The vibration emission value during actual use of
the power tool can differ from the declared value depending on the
ways in which the tool is used dependant on the following examples
and other variations on how the tool is used:
The tool being in good condition and well maintained
The use the correct accessory for the tool and ensuring it is sharp
and in good condition.
The tightness of the grip on the handles and any anti vibration
accessories are used.
And the tool is being used as intended by its design and these
instructions.
This tool may cause hand-arm vibration syndrome if its use is
not adequately managed.
Warning: To be accurate, an estimation of exposure level in
the actual conditions of use should also take account of all parts of
the operating cycle such as the times when the tool is switched off
Page 10

and when it is running idle but not actually doing the job. This may
significantly reduce the exposure level over the total working period.
Help to minimize your vibration exposure risk.
Maintain this tool in accordance with these instructions and keep
well lubricated (where appropriate)
If the tool is to be used regularly then invest in anti vibration acces-
sories.
Avoid using tools in temperatures of 100C or less
Plan your work schedule to spread any high vibration tool use across
a number of days.

Operating instructions
Note: Before using the tool, read the instruction book carefully.
INTENDED USE
The machine is intended for dry sanding of wood,plastic, metal and
filler material as well as painted surfaces.
Machines with electronic control are also suitable for polishing.
KNOW YOUR RANDOM ORBIT SANDER
vibrafree™ RANDOM ORBIT Sander are uniquely designed with
two counter balanced sanding pads that always move in opposite
directions to each other. This design platform virtually cancels out
the sander’s vibration in every load condition. This active vibration
canceling technology makes this sander more comfortable and
easy to use, taking the vibration out of the sander, the workpiece,
your hands and arms, and putting this energy to work sanding and
removing material.
1
FITTING THE SANDING PAPER (See Fig A)
Sanding paper is easily attached on the pad of your sander. Fit the
inner spot paper over the plate so that it covers the entire area,
push and slightly twist to make sure the coated sanding paper is
even on the plate. Operate like this when fit the outer ring paper.

Make sure the sanding paper is even with the edges and that the
sanding paper is taut on the pad.
Remove the abrasive paper by pinching an edge and peeling off
(See Fig B)
CYCLONIC DUST BOX (See Fig C)
2
A) ATTACH THE CYCLONIC DUST BOX
Your sander is equipped with a cyclonic dust box. To attach, slide
the box onto the outlet piece and take care that the latching lever
engages.
Caution: To prevent the possibility of sanding dust or foreign
body being thrown into your face or eyes, never attempt to use
your sander without the box properly installed.
B) EMPTY THE CYCLONIC DUST BOX (See Fig D1, D2)
For more efficient operation, empty the cyclonic dust box every
5-10mins. This will permit the air to flow through the box better.
To empty the box, press the latching lever in and pull off the box.
Then press the button at the rear of the box to open it, and shake
out dust.
3
USING THE DUST EXTRACTION ADAPTER (See Fig.E)
Your sander is equipped with a dust adapter, which is designed for
collect dust task. To attach, slide the adapter onto the outlet piece
and take care that the latching lever engages. Then connect the

hose of a vacuum cleaner. First please turn on the vacuum cleaner,
and then turn on the sander. If you stop sanding, first turn off the
sander, then turn off your vacuum cleaner.
4
OPERATING THE SWITCH (See Fig F)
To start your sander, depress the protective cover over the switch
at the position marked“I”. To stop your sander, depress the
protective cover at the position marked “0”.
5
ORBITAL SANDING
Guide your sander parallel to the working surface and move it in
circles or in a cross pattern. Do not tilt the tool in order to avoid
deep unwanted sanding marks. The amount of material removed is
determined by the speed of the sanding disc and the grit size used.
The speed of the sanding disc diminishes relative to the pressure
applied to the tool. For faster removal, do not increase pressure on
the tool, but use a coarser grit size.
6
SELECTING THE RIGHT GRADE OF SANDPAPER
• Different grades of sanding paper can be purchased from good
DIY shops. Available grades are Coarse, Medium and Fine.
• Use coarse grits to sand down rough finishes, medium grit to
smooth the work and fine grit to finish off.
• The higher the grade number, the finer the grit. For rough work
F
Page 14
14
start with a low grade of grit. (e.g. 60 grit) and change to a higher,
finer grade (e.g. 120 or 180 grit) for finishing. If you use a fine grade
for rough surfaces it will soon clog and need changing.
• It is best to make a trial run on a scrap piece of material to
determine the optimum grades of sandpaper for a particular job.
7
SANDING PLATE BRAKE
An integrated sanding plate brake reduces the speed when running
at no load so that scoring is avoided when placing the machine on
the work piece. A continuously increasing no-load speed over the
course of time indicates that the sanding plate brake is worn and
must be replaced by an authorized customer service location.
Working hints for your random
orbit sander
If your power tool becomes too hot, especially when used at low
speed, set the speed to maximum and run it with no load for 2-3
minutes to cool the motor. Avoid prolonged usage at very low
speeds. Always use sand paper that is suitable for the material you
want to sand.
Always ensure the work-piece is firmly held or clamped to prevent
movement.
Any movement of the material may affect the quality of the sanding
finish.
Start your sander before sanding and turn it off only after you stop
sanding. For the best results, sand wood in the direction of the
grain.
Do not start sanding without having the sandpaper fitted.
Do not allow the sand paper to wear away it will damage the base-
plate. The guarantee does not cover base-plate wear and tear.
Use coarse grit paper to sand rough surfaces, medium grit for
smooth surfaces and fine grit for the final surfaces. If necessary,
first make a test run on scrap material.
Use only good quality sand paper.
The sand paper controls the sanding efficiency, not the amount of
Page 15
15
force you apply to the tool. Excessive force will reduce the sanding
efficiency and cause motor overload. Replacing the sand paper
regularly will maintain optimum sanding efficiency.
