This Product Conforms To 98/37/EEC Regulations

All hand held power tools vibrate to some extent, and this vibration is transmitted to the operator via
the handle, or hand used to steady the tool. Vibration from about 2 to 1500 hertz is potentially
damaging and is most hazardous in the range from about 5 to 20 hertz.

Operators who are regularly exposed to vibration may suffer from Hand Arm Vibration Syndrome
(HAVS), which includes ‘dead hand’, ‘dead finger’, and ‘white finger’. These are painful conditions and
are widespread in industries where vibrating tools are used.

The health risk depends upon the vibration level and the length of time of exposure to it……in effect, a
daily vibration dose.

Tools are tested using specialised equipment, to approximate the vibration level generated under
normal, acceptable operating conditions for the tool in question. For example, a grinder used at 45°
on mild steel plate, or a sander on softwood in a horizontal plane etc.

a’

These tests produce a value‘
average vibration level of all tests taken, in three axes where necessary. This value appears in the
panel below.

a

’ values in excess of 2.5 m/s2 are considered hazardous when used for prolonged periods. A tool with

‘
a vibration value of 2.8 m/s2 may be used for up to 8 hours (cumulative) per day, whereas a tool with a
value of 11.2 m/s2 may be used for ½ hour per day only.

The graph shows the vibration value against the maximum time the respective tool may be used, per
day.

It should be noted that if a tool is used under
abnormal, or unusual conditions, then the vibration
level could possibly increase significantly. Users must
always take this into account and make their own
risk assessment, using the graph above as a
reference.

Some tools with a high vibration value, such as
impact wrenches, are generally used for a few
seconds at a time, therefore the cumulative time
may only be in the order of a few minutes per day.
Nevertheless, the cumulative effect, particularly
when added to that of other hand held power tools
that may be used, must always be taken into
account when the total daily dose rate is
determined.

TROUBLE SHOOTING

ELECTRICAL CONNECTIONS

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 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.

The Dust Is Not Extracted

Dust bag is full (empty waste bag), dust extractor flue is blocked, this is usually caused by
allowing bag to become too full, (remove and empty bag, also clear blockage).

Note :

Ensure sander is switched OFF and isolated from the mains by removing plug from socket.

MAINTENANCE

WARNING!

Make sure that the sander is switched off and disconnected from the mains supply before
starting any cleaning or maintenance procedures.

After use clean out any accumulated dust or chippings etc. Keep the cooling vents
clear. If the sander should become too hot, run it for 2 minutes without load.

Clean the housing with a soft cloth. Any worn or damaged parts should be replaced by
qualified personnel. Keep the handles clean and free from oil and grease. There are no
user serviceable parts inside this sander. Refer to qualified service personnel if internal
maintenance is required.

This product is provided with a standard 13 amp, 230 volt (50Hz), BS 1363 plug, for

• By depressing the switch fully for maximum speed or less for slower speed.

• To control the maximum speed, turn the knob located on the trigger
switch from A(lower) - F(Faster).

Variable speed control

Using The Sander

a) Before switching the sander ON, make sure that there are no nails or other objects

in the area to be sanded.

b) Switch the sander ON before applying it to the work surface. Move the sander

evenly over the work area. Never allow the sander to stay in one place for too
long as this will give an uneven finish.

c) Hold the sander with both hands, using both handles.

d) Replace worn sanding paper. The performance of your sander is dependant on

the quality of the sanding paper being used. Remove the sander from the work
area before switching it OFF, (wait until motor has stopped fully before putting tool
down).

Note :

There is a spindle lock button near the support grip, this button has no function on this
model.

Sanding Hints

• Do not apply excessive pressure to the sander. The weight of the sander alone is
sufficient for normal use

• Always start your sander before it comes into contact with the workpiece, and do
not switch off until it has been lifted off the workpiece.

• Always use both hands to hold the sander and clamp the workpiece for added
stability and safety.
