Specific safety rules
Always wear safety glasses or eye shields when using the
sander. Everyday eyeglasses have only impact-resistant lenses;
they are NOT safety glasses. Following this rule will reduce the
risk of serious personal injury.
Always wear a face mask or dust mask. Following this rule will
reduce the risk of serious personal injury.
Always wear hearing protection during extended periods
of operation. Following this rule will reduce the risk of serious
personal injury.
Warning: Some dust particles created by power sanding,
sawing, grinding, drill and other construction jobs contain
chemicals known to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are:
Lead from lead-based paints.
Crystalline silica from bricks and cement and other masonry
products.
Arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending upon how often
you do this type of work.
To reduce your exposure to these chemicals:
Work in a well-ventilated area.
Work with approved safety equipment, such as those dust masks
that are specially designed to bag microscopic particles.
Accessories
Sander paper 1pc
Paper hole punch 1pc
Dust bag 1pc
Use 1/4 sheet sanding paper of the following size:
140 x 115mm for no hook & loop (Clamp only)
102 x 115mm for hook & loop
If using sanding paper without dust holes ,you must use the
paper punch to make holes.
We recommend that you purchase your accessories from the same
store that sold you the tool. Use good quality accessories marked
with a well-known brand name. Choose the type according to the
work you intend to undertake. Refer to the accessory packaging for
further details. Store personnel can assist you and offer advice.

Additional safety rules for your
palm sander
Remove the plug from the socket before carrying out any
adjustment, servicing or maintenance.
Fully unwind cable drum extensions to avoid potential overheating.
When an extension cable is required you must ensure it has the
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
rating plate.
Your tool is double insulated for additional protection against a
possible electrical insulation failure within the tool.
Always check walls, floors and ceilings to avoid hidden power
cables and pipes.
After long working period external metal parts and accessories
could be hot.
If possible, ensure the work-piece is firmly clamped to prevent
movement.
Your palm sander is a hand held tool, do not clamp your finishing
sander.
Before sanding, check the area is free of nails, screws, etc.
Never stop the palm sander by applying a force to the base-plate.
Only use paper in good condition. Do not use torn or worn paper.
Do not sand material containing asbestos due to a health risk.
Do not eat or drink in the working area of the sander.
Do not allow people to enter the working area without wearing a
dust mask.
Where possible, seal off the working area to contain the dust for
later removal.
Your tool is designed for dry sanding only, not wet sanding.
Your tool is designed for general purpose light polishing of wood
and metals.
Do not sand magnesium material due to the risk of fire.

Operating instructions
Note: Before using the tool, read the instruction book carefully.
ON/OFF SWITCH
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”.
HAND GRIP AREA
You can operate your sander with one hand (see A).
CHANGING THE SANDING PAPER
To remove the sandpaper, lift up the clamp lever (4) and move away
from the lever lock (5) (see B). The sandpaper clamp (3) is now loose.
Repeat with the other clamp on the opposite side of your sander.
To fit new sandpaper, insert approximately 5mm of one end of the
sandpaper under the sandpaper clamp (3) until the paper contacts
the housing wall (see B). Lift up the clamp lever (4) and move it to the
lever lock position.
Press the sandpaper around the base-plate shape as tight as possible
and fix the end under the other sandpaper clamp (3). Check the
sandpaper is square to the base-plate and remove and refit again.
if not correct, remove and refit it again.
Always, ensure the sandpaper is tight over the base-plate and
secured underneath both locked clamps (3). This will ensure safe and
efficient sanding performance.
CHANGING HOOK & LOOP SANDING PAPER
The sanding paper and baseplate are provided with a hook and loop

9
ORBITAL SANDING
Your sander operates in small circular rotations which allows efficient
material removal.
Operate your sander in long sweeping movements across your
workpiece and even across the grain. For a finer finish, always use a
fine grain sandpaper and only move the sander in the direction of the
grain and never across the grain.
Do not allow your sander to remain in the same position otherwise
you will remove material and create and uneven surface.

attachment system to allow quick and easy changing of the sanding
and polishing accessories. Remove any dust or other objects from
the hook and loop on the baseplate and sanding paper. Position the
sanding paper evenly on the baseplate and firmly press down to
attach them together. If the sanding paperhas dust extraction holes
you must align these with the holes in the baseplate, otherwise the
dust extraction will not function. To remove the sanding paper lift one
corner of the paper and pull it off from the baseplate (See B.2).
PAPER PUNCH
If using sanding paper without dust holes, use the paper punch (7)
to perforate the holes to ensure correct dust extraction. Position the
punch over the base-plate (8) with the punch sides on the edges of
the base-plate (see C). Press the punch into the base-plate to punch
holes into the sanding paper. Then remove the punch and check all
the holes have been formed correctly.
DUST BAG
Always operate your sander with the dust bag fitted. For the best
performance always empty the dust bag in time. Open the zip and
empty the dust from the bag. To remove the bag ,slide the mounting
bracket out and away from the sander ( (See D). To refit the bag,
firmly push the mounting bracket into the location on the sander
housing (See E).
For best performance always empty the dust bag when it is half full.
FLUSH SANDING FACILITY
Your sander can sand flush on three sides of the base-plate which
allows easy access to corners and edges of moulding (see F).

Work hints for your palm sander
If your power tool becomes too hot, run no load for 2-3 minutes to
cool the motor.
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 off only after stopping
sanding. For best results sand wood in the direction of the grit.
Do not start sanding without sandpaper fitted.
Do not allow the sandpaper 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 on scrap
material.
Use only good quality sandpaper.
The sanding efficiency is controlled by the sandpaper not the amount
of force you apply to the tool. Excessive force will reduce the sanding
efficiency and cause motor overload. Replacing the sanding paper
regularly will maintain optimum sanding efficiency.
Maintenance
Remove the plug from the socket before carrying out any
adjustment, servicing or maintenance.
Your power tool requires no additional lubrication or maintenance.
There are no user serviceable parts in your power tool. Never use
water or chemical cleaners to clean your power tool. Wipe clean with
a dry cloth. Always store your power tool in a dry place. Keep the
motor ventilation slots clean. Keep all working controls free of dust.
Occasionally you may see sparks through the ventilation slots. This
is normal and will not damage your power tool. If the supply cord is
damaged, it must be replaced by the manufacturer, its service agent
or similarly qualified persons in order to avoid a hazard.
Environmental protection
Waste electrical products should not be disposed of with
household waste. Please recycle where facilities exist. Check
with your local authorities or retailer for recycling advice.
