POWER TOOL SAFETY
WARNING:
Read all safety warnings and 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.
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.
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 a residual
current device (RCD) protected supply. Use of a ground fault circuit interrupter
(GFCI) reduces the risk of electric shock.
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.

5
connecting to power source and/or battery pack, picking up or carrying the
tool. Carrying power tools with your finger on the switch or energizing 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 jewellery. Keep your hair,
clothing, and gloves away from moving parts. Loose clothes, jewellery or long hair

SPECIFIC SAFETY RULES FOR 1/3 SHEET
SANDERS
WARNING:
Know your 1/3 sheet sander. Do not plug in the sander until you have read and
understand this Instruction Manual.
Learn the tool’s applications and limitations, as well as the specific potential
hazards related to this tool. Following this rule will reduce the risk of electric
shock, fire, or serious injury.
Always wear eye protection. Any power tool can throw foreign objects
into your eyes and cause permanent eye damage. ALWAYS wear
safety goggles (not glasses) that comply with ANSI safety standard
Z87.1.
Everyday glasses have only impact resistant lenses. They ARE NOT safety glasses.
WARNING: Glasses or goggles not in compliance with ANSI Z87.1 could
cause serious injury when they break.
WARNING: Always use a dust mask when sanding.
WARNING: Always use hearing protection when sanding, particularly during
extended periods of operation.
WARNING: Always unplug the tool from the power source before changing
the sandpaper and when cleaning the tool.
Do not wear gloves, neckties or loose clothing.
Secure the workpiece. Use clamps or a vise to hold the work when practical. It is
safer than using your hand and it frees both hands to operate the tool.
Do not sand material too small to be securely held.
Make sure there are no nails or foreign objects in the part of the workpiece to be
sanded.
Always keep hands out of the path of the sanding pad. Avoid awkward hand

GUIDELINES FOR EXTENSION CORDS
Make sure your extension cord is the proper size. When using an extension
cord, be sure to use one heavy enough to carry the current the tool will draw. An
undersized cord will cause a drop in line voltage resulting in loss of power and
overheating. The table on at right shows the correct size to use according to cord
length and nameplate ampere rating. If in doubt, use the next heavier gauge. The
smaller the gauge number the heavier the cord.
Be sure your extension cord is properly wired and in good condition. Always
replace a damaged extension cord or have it repaired by a qualified electrician
before using it. Protect your extension cord from sharp objects, excessive heat and
damp or wet areas.
Use a separate electrical circuit for your power tools. This circuit must not be
less than 14 gauge wire and should be protected with either a 15A time delay fuse
or circuit breaker. Before connecting the power tool to the power source, make sure
the switch is in the OFF position and the power source is the same as indicated on
the nameplate. Running at lower voltage will damage the motor.
WARNING: Repair or replace damaged or worn extension cords
immediately.
Select the appropriate extension cord gauge and length using the chart below.

ASSEMBLY AND OPERATING
WARNING: The tool should never be connected to a power supply when you
are assembling parts, making adjustments, cleaning, performing maintenance,
or when the tool is not in use. Disconnecting the tool will prevent accidental
starting that could cause serious injury.
SANDING SHEET SELECTION
Selecting the correct size, grit and type of sand paper is extremely important step in
achieving a high quality sanded finish. Aluminum oxide, silicon carbide, and other
synthetic abrasives are best for power sanding.
Natural abrasives, such as flint and garnet are too soft for economical use in power
sanding. In general, coarse grit will remove the most material and finer grit will
produce the best finish in all sanding operations. The condition of the surface to be
sanded will determine which grit will do the job. If the surface is rough, start with
a coarse grit and sand until the surface is uniform. Medium grit may then be used
to remove scratches left by the coarser grit and finer grit used for finishing of the
surface. Always continue sanding with each grit until surface is uniform.
WARNING: Do not use sander without sandpaper, doing so will damage the
cushion. For coarse-sanding, e.g. of rough, unplaned beams and boards: Coarse 40,
60 Grit. For face sanding and removing small irregularities : Medium 80, 100, 120
Grit. For finishing and fine sanding ofallmaterials: Fine 150,180, 240, 320, 400 Grit.
INSTALLING SANDPAPER
WARNING: Always disconnect the machine from the power supply before
adjustment, changing accessories and maintenance.
1. Push the clamp lever inwards to clear the securing tag. The lever is under spring
tension. Allow the lever to raise upwards and then manoeuvre outwards and
downwards, Fig 4.
2. This allows the clamp to release its grip on the sander base. Repeat the
operation for other side.
3. Select an abrasive paper with the correct grit corresponding to the work to
be carried out. Inspect the sandpaper before use and do not use if broken or
defective.

4. Position one end of the sandpaper under the clamp and re-secure.
5. The sandpaper should be pulled taught and follow the contours of the sander
base. Ensure alignment of dust extraction holes with the holes in the sandpaper
sheets. Position the other end of the sandpaper under the clamp and re-secure.
SANDPAPER PUNCH
A sandpaper punch template has been supplied with your sander for aligning and
punching holes in sandpaper. The punched holes must align with the holes in the
sander base.
Attach the sandpaper onto the sander. Align the sander base over the paper punch.
Push the sander down onto the paper punch, Fig 5.
TURNING THE SANDER ON & OFF
trigger to turn the sander OFF.
Lock-On Button
The sander is equipped with a continuous operation button, which is convenient
when continuous cutting for extended periods of time is required. To lock-on,
1. Release the lock-on button and your sander will continue running.
2.
NOTE: If you have the lock-on feature engaged during use and your sander
becomes disconnected from power supply, disengage the lock-on feature

VARIABLE SPEED CONTROL
The variable speed control allows the sander to develop a no load speed that can be
adjusted from 6000 to 12000min-1. The variable speed dial is located on the front
of the sander, Fig 7.
The speed can be set according to the sanding purpose or work-piece's surface you
will be using.
FITTING THE DUST COLLECTION BAG
The dust collection bag provides a dust collection system for the sander. Sanding
dust is drawn up through the holes of the sanding base and collected in the dust
collection bag during sanding.
Unplug the sander.
Using a slight twisting motion, firmly slide the dust collection bag onto the blower
exhaust on the sander.
EMPTYING THE DUST COLLECTION BAG
half full. This will permit the air to flow through the dust collection bag better. Always
empty and clean the dust collection bag thoroughly upon completion of a sanding
operation and before placing the sander in storage.
WARNING: Collected sanding dust from sanding surface coatings such as
polyurethanes, linseed oil, etc., can self-ignite in your sander dust collection
bag or elsewhere and cause fire. To reduce the risk of fire always empty your
dust collection bag frequently (10- 15 minutes) while sanding and never store
or leave a sander without totally emptying its dust collection bag.
Unplug the sander. Remove the dust collection bag from the sander. Shake out the
dust. Reattach the dust collection bag to the sander.
OPERATING THE SANDER
Secure the workpiece to prevent it from moving under the sander. Unsecured
workpieces could be thrown towards the operator, causing injury.
WARNING: Keep your head away from the sander and the sanding area.
Your hair could be drawn into the sander causing serious injury.
Place the sander on the workpiece so that all of the sanding sheet surface is in
contact with the workpiece.
CAUTION: Avoid damaging the motor from overheating, be careful not to
let your hand cover the air vents.
Turn on the sander and move it slowly over the workpiece.
NOTE: Hold the sander in front and away from you, keeping it clear of the
workpiece. Start sander and let the motor build to its maximum speed, then
gradually lower the sander onto the workpiece. Move the sander slowly across the
workpiece using small circular motions.
Do not force. The weight of the unit supplies adequate pressure, so let the sanding
disc and sander do the work. Applying additional pressure only slows the motor,

rapidly wears sanding sheet and greatly reduces sander speed. Excessive pressure
will overload the motor causing possible damage from motor overheating and can
result in inferior work. Any finish or resin on wood may soften from the frictional heat.
Do not allow sanding on one spot too long as the sander’s rapid action may remove
too much material, making the surface uneven.
Extended periods of sanding may tend to overheat the motor. If this occurs, turn
sander, then remove it from workpiece. Allow the tool to cool down.
APPLICATIONS
You may use the sander for the purposes listed below:
• Sanding on wood surfaces.
• Removing rust from and sanding steel surfaces.
• Polishing and scrubbing porcelain and metal.
CAUTION: Keep the cord away from the sanding pad and position the cord so
that it will not be caught on lumber, tools, or other objects during sanding.
WARNING: Always wear safety goggles or safety glasses with side shields
when operating the products. Failure to do so could result in dust, shavings, or
loose particles being thrown into your eyes, resulting in possible serious injury.

based products, penetrating oils, etc. to come in contact with plastic parts.
They contain chemicals that can damage, weaken or destroy plastic.
DO NOT abuse power tools. Abusive practices can damage the tool as well as the
workpiece.
WARNING: DO NOT attempt to modify tools or create accessories not
recommended. Any such alteration or modification is misuse and could result
in a hazardous condition leading to possible serious injury. It will also void the
warranty.
It has been found that electric tools are subjected to accelerated wear and possible
premature failure when they are used on fiberglass boats and automotive parts,
wallboard, spackling compounds or plaster. The chips and grindings from these
materials are highly abrasive to electric tool parts such as bearings, brushes,
commutators, etc. Consequently, it is not recommended that this tool be used
for extended work on any fiberglass material, wallboard, spackling compounds or
plaster. During any use on these materials it is extremely important that the tool is
cleaned frequently by blowing the dust out of the tool with an air jet.
WARNING: Always wear safety goggles or safety glasses with side shields
during all sanding operations. It is critical that you also wear safety goggles or
safety glasses with side shields and a dust mask while blowing dust out of the
sander with an air jet. Failure to take these safety precautions could result in
permanent eye or lung damage.
