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 or gases. 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. Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.

5. 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 work 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.

OPERATION
FITTING THE SANDING SHEET
With the sander disconnected from the power supply, select the sanding
sheet appropriate for the task and attach it to the base plate as follows. Either
plain sanding sheets or prepared sheets for hook and loop attachment can
be used.
PAPER SANDING SHEETS
1. Lift the retaining clips to the open
position and insert one end of the
sanding sheets under the
retaining clip.
2. Set the clip back in the retaining
position to hold the sheet and
lightly stretch it over the
baseplate, ensuring it is not folded
or wrinkled, then position it under
the other retaining clip.
3. Lock the second clip back into the retaining position.
4. Check the paper lays straight and
flat on the baseplate. If not,
release either clip and adjust the
sheet before resetting the clip.
HOOK AND LOOP SANDING SHEETS
1. Align the sanding sheet so that
the holes align with those in the
baseplate, press the sheet evenly
onto the base plate to attach it.

STARTING & STOPPING THE SANDER
Ensure the sander is switched OFF
before plugging into the power
supply.
1. Ensure the sander is switched OFF
before plugging into the power
supply.
2. Switch the machine ON or OFF by
sliding the switch forward and
backward.
OPERATING TECHNIQUE
1. Select the operating speed
appropriate to the job in hand.
The speed required will be
dependant on the material and
will be determined by a practical
trial.
• Speeds are stated in the
specification.
2. Always hold the sander securely.
3. Regularly check the condition of
the sanding sheet and replace it when necessary.
4. 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.
5. Always use sanding sheet that is in top condition, as damaged sheets will
cause damage to the baseplate. Please note, that baseplates are NOT
covered by the warranty.
6. Always place the sander on the workpiece before switching ON to prevent
the workpiece from being badly scored by the edge of the moving
abrasive.
7. Move the sander evenly and smoothly over the surface of the workpiece
with only light, even pressure. This helps to expel dust particles and produce
an even finish and will also prolong the life of the sanding sheet.
8. Let the sander do the work and ensure the sander is flat on the work
surface. Never apply heavy pressure as this will not only produce an
uneven finish but will overload the motor causing it to burn out.
9. Be cautious when sanding the end of a workpiece as the sheet could
come off the baseplate and damage it in the process.

MAINTENANCE
Your sander will operate over a long period of time with a minimum of
maintenance. Continuous satisfactory operation depends upon proper care.
Regularly clean the ventilation slots using a soft dry brush or dry cloth. Do not
use any abrasive or solvent-based cleaner.
A damaged power cable should be replaced by your CLARKE dealer or
qualified electrician.
The bearings in this sander are sealed for life and require no maintenance.
FAULTFINDING
SANDER IS OVERHEATING
This indicates the machine is dirty. Clean the ventilation holes and blow out
with compressed air. Always wear eye prodection when using compressed air.
Overloading the machine will also cause overheating. Do not use for heavy
duty work and 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.
POOR ABRASION
If the sander is not removing material efficiently, check the sanding sheet. If
the abrasive is worn down replace the sheet. The sanding sheet must always
be stored in a dry place as if it allowed to become damp, the abrasive
particles will detach from the sheet and will not abrade.
WARNING: BEFORE PERFORMING ANY MAINTENANCE, SWITCH OFF AND
UNPLUG THE SANDER.
