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. 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 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.

3. Remove all dust after sanding.

the sander as far as it will go and
then twisting clockwise until it
locks into place.

• The filter housing has lugs to

align and secure it. Note their
position matches those on the
sander body before assembly.

NOTE: The user should still wear a

face mask to prevent the inhalation of dust particles.

NOTE: Due to the nature of the tool, some of the dust produced will be forced

into the surrounding atmosphere and will not be collected.

OPERATION

FITTING THE SANDING SHEET

1. 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.

PLAIN SANDING SHEETS

1. Lift the paper retaining clips to the
open position and insert one end
of the sanding sheet under the
retaining clip. 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. Lock the
second clip back into the
retaining position.

2. Check the sheet 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 are aligned with those in
the base plate (this is necessary
for dust extraction), press the
sheet evenly onto the base plate
to attach it.

REPLACEMENT SHEETS

The following sanding sheets are available from your CLARKE dealer.

STARTING & STOPPING THE SANDER

1. Ensure the sander is switched OFF
before plugging into the power
supply.

2. Switch the machine ON or OFF by
pressing the rocker switch.

3. Lock the switch in the ON position
if required by pressing in the
trigger lock button on the side of
the handle.

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. Also select the abrasive grade
appropriate to the task.

3. Always hold the sander securely.

4. Regularly check the condition of the sanding sheet and replace it when
necessary.

5. 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 final finish.

6. Always use a sanding sheet that is in top condition, damaged backing will
cause damage to the base plate surface. Please note that base plates are
NOT covered by the warranty.

7. Always place the sander on the workpiece before switching ON. This will
prevent the workpiece from being scored by the edge of a moving
sanding sheet.

8. Move the sander evenly over the surface of the workpiece with light
pressure. This helps to expel dust particles and produce an even finish and
will also prolong the life of the sanding sheet.

9. Let the sander do the work ensuring the sander is flat on the work surface.
DO NOT apply heavy pressure as this will not only produce an uneven finish
but will overload the motor causing it to burn out.

10. Wait until the sander has stopped completely before putting it down.

MAINTENANCE

WARNING: BEFORE PERFORMING ANY MAINTENANCE, SWITCH OFF AND
UNPLUG THE SANDER.

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 motor ventilation slots using a soft dry brush or dry cloth to
remove dust. Do not use any abrasive or solvent-based cleaner.

A damaged power cable should be replaced by your CLARKE dealer or
qualified electrician.

There are no user-serviceable parts in this sander. 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 protection 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 paper 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.
