POWER TOOL SAFETY WARNINGS
WORK AREA
1. Keep the work area clean and well lit. Cluttered and dark areas invite
accidents.
2. 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.
3. Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. Never modify the plug in any way.
Do not use adaptor plugs with earthed (grounded) power tools. Unmodified
plugs and matching outlets will reduce the risk of electric shock.
2. Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
3. Do not abuse the cable. Never use it for carrying, pulling or unplugging the
power tool. Keep the cable away from heat, oil, sharp edges or moving
parts. Damaged or entangled cables increase the risk of electric shock.
4. When operating a power tool outdoors, use an extension cable suitable for
outdoor use. Use of a cable suitable for outdoor use reduces the risk of
electric shock
5. If operating the power tool in a damp location is unavoidable, use a
residual current device (RCD) protected supply.
PERSONAL SAFETY
1. 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 personal injury.
2. Use safety equipment. Always wear eye protection. Safety equipment such
as dust mask, non-skid safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal injuries.
3. Avoid accidental starting. Ensure the switch is in the off position before
plugging in. Carrying power tools with your finger on the switch or plugging
in power tools that have the switch on invites accidents.
4. Remove any wrench before turning the power tool on. A wrench left
attached to a rotating part may result in personal injury.

5. Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
6. 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.
POWER TOOL USE AND CARE
1. Do not force the power tool. Use the correct accessories for your
application. The correct power tool will do the job better and safer at the
rate which it was designed for.
2. 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.
3. Disconnect the plug from the power source before changing accessories,
or storing power tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
4. Store idle tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate it. Power tools
are dangerous in the hands of untrained users.
5. 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.
6. Use the power tool and accessories in accordance with these instructions
and in the manner intended, taking into account the working conditions
and the work to be performed. Use of the power tool for operations
different from intended could result in a hazardous situation.
7. The performance of this tool may vary, depending upon variations in line
voltage. Extension cable usage may also affect performance.
SERVICE
1. Have your power tool serviced by qualified service personnel using only
identical replacement parts. This will ensure that the safety of the power
tool is maintained.
ADDITIONAL SAFETY WARNINGS FOR SANDERS
1. Secure the workpiece to a stable platform. Holding the workpiece by hand
or against your body may lead to loss of control.

2. Dust arising from sanding may endanger the health of the operator and
possible bystanders. Wear a dust mask and ensure that persons entering
the work area are also protected.
3. Remove all dust after sanding.
4. Take care when sanding lead based paint or when sanding wood or metal
which may produce toxic dust, - do not let children or pregnant women
enter the work area.
VIBRATION
The declared vibration emission values stated in the specifications have been
measured in accordance with a standard test method provided by EN 60745
and may be used for comparing one tool with another. The declared vibration
emission value may also be used in a preliminary assessment of exposure.
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. THE VIBRATION LEVEL MAY
INCREASE ABOVE THE LEVEL STATED.

ELECTRICAL CONNECTIONS
Before switching the product on, make sure that the voltage of your electricity supply is
the same as that indicated on the rating plate. This product is designed to operate on
230VAC 50Hz. Connecting it to any other power source may cause damage.
This product may be fitted with a non-rewireable plug. If it is necessary to change the
fuse in the plug, the fuse cover must be refitted. If the fuse cover becomes lost or
damaged, the plug must not be used until a suitable replacement is obtained.
If the plug has to be changed because it is not suitable for your socket, or due to
damage, it should be cut off and a replacement fitted, following the wiring instructions
shown below. The old plug must be disposed of safely, as insertion into a mains socket
could cause an electrical hazard.
If the colours of the wires in the power cable of this product do not correspond
with the markings on the terminals of your plug, proceed as follows.
• The wire which is coloured Blue must be connected to the terminal
which is marked Nor coloured Black.

• On very uneven surfaces or when removing layers of paint, start with a
coarse grit. On other surfaces, start with a medium grit. In both cases,
gradually change to a fine grit for a smooth finish.
MAINTENANCE
After use clean out any accumulated dust etc. Keep the cooling vents clear. If
the sander should become too hot, run it for 2 minutes without load.

Your sander has been designed to operate over a long period of time with a
minimum of maintenance. Continuous satisfactory operation depends upon
proper care.

abrasive or solvent-based cleaner.
• A damaged power cable should be replaced by your Clarke dealer or
a qualified electrician.

TROUBLE SHOOTING
SANDER IS OVERHEATING
This indicates the machine is dirty. Clean the ventilation holes, and blow out
with compressed air or clean with a dry cloth.
Overloading the machine will also cause overheating. Do not apply excessive
pressure.
EXCESSIVE SPARKING OCCURS
This indicates worn brushes. This problem is quickly remedied but you should
consult your CLARKE dealer for parts and advice.
SANDER DOES NOT OPERATE WHEN SWITCHED ON
Check to ensure the fuse is sound and replace if necessary. If the fuse is sound
or blows repeatedly, consult your CLARKE dealer.
THE DUST IS NOT EXTRACTED
