SAFETY PRECAUTIONS

WARNING:

As with all machinery, there are certain hazards involved with their operation

and use. Exercising respect and caution will considerably lessen the risk of

personal injury. However, if normal safety precautions are overlooked or

ignored, personal injury to the operator or damage to property, may result.

1. ALWAYS Learn the machines’ applications, limitations and the specific potential hazards
peculiar to it.Read and become familiar with the entire operating
manual.

2. ALWAYS use a face or dust mask if sanding operation is particularly
dusty.

3. ALWAYS check for damage. before using the machine, any damaged
part, should be checked to ensure that it will operate properly, and
perform its intended function.
Check for alignment of moving parts, breakage of parts, mountings, and any other
condition that may affect the machines’ operation. Any damage should be properly
repaired or the part replaced. If in doubt, DO NOT use the machine. Consult your
local dealer.

4. ALWAYS disconnect the tool/machine from the power supply before servicing and when
changing accessories.

5. ALWAYS wear safety goggles, manufactured to the latest European Safety Standards.
Everyday eyeglasses do not have impact resistant lenses, they are not safety glasses.

6. ALWAYS keep work area clean. cluttered areas and benches
invite accidents.

7. ALWAYS ensure that adequate lighting is available. A minimum
intensity of 300 lux should be provided. Ensure that lighting is
placed so that you will not be working in your own shadow.

8. ALWAYS keep children away. all visitors should be kept a safe distance from the work
area, especially whilst operating the machine.

9. ALWAYS maintain machine in top condition. keep tools/machines
clean for the best and safest performance. follow maintenance
instructions.

10. ALWAYS handle with extreme care do not carry the tool/machine
by its’ electri C cable, or yank the cable to disconnect it from the
power supply .

11. ALWAYS ensure the switch is off before plugging in to mains. Avoid accidental starting.

12. ALWAYS concentrate on the job in hand, no matter how
trivial it may seem.be aware that accidents are caused
by carelessness due to familiarity.

13. ALWAYS keep your proper footing and balance at all times

- don’t overreach. For best footing, wear rubber soled
footwear. keep floor clear of oil, scrap wood, etc.

to rain. keep your work area well illuminated. do not use in explosive
atmosphere (around paint, flammable liquids etc.). Avoid
dangerous environment.

ADDITIONAL PRECAUTIONS FOR ORBITAL SANDERS

1. Do not use the machine if the electric cable, plug or the motor, is in poor condition.

2. Keep the mains cable well away from the sander, and ensure an adequate electrical

supply is close at hand so that the operation is not restricted by the length of the
cable.

3. Switch the machine OFF immediately the task is completed.

4. Never allow the ventilation slots in the machine to become blocked.

5. Always use the appropriate sanding medium for the material being worked. Both

metal and wood sanding media of various grades are available from all good
hardware stores.

6. Do not attempt any electrical repair yourself. Consult a qualified electrician, or our

Service Dep’t on 020 8988 7400

Additionally, please keep these instructions in a safe place for future reference.

ELECTRICAL CONNECTIONS

This product is provided with a standard 13 amp, 230 volt (50Hz), BS 1363 plug, for connection
to a standard, domestic electrical supply. Should the plug need changing at any time,
ensure that a plug of identical specification is used.

WARNING

This appliance is Doubly Insulated, and the two wires in the mains lead should

be wired up in accordance with the following colour code:

BLUE - NEUTRAL

BROWN - LIVE

•

Connect the BLUE coloured cord to the plug terminal marked a letter “N”

• Connect the BROWN coloured cord to the plug terminal marked a letter “L”

If this appliance is fitted with a plug which is moulded on to the electric cable (i.e. non­rewireable) please note:

1. The plug must be thrown away if it is cut from the electric cable. There is a danger of
electric shock if it is subsequently inserted into a socket outlet.

2. Never use the plug without the fuse cover fitted.

3. Should you wish to replace a detachable fuse carrier, ensure that the correct
replacement is used (as indicated by marking or colour code).

4. Replacement fuse covers can be obtained from your local dealer or most electrical
stockists.

FUSE RATING

The fuse in the plug must be replaced with one of the same rating (5 amps) and this
replacement must be ASTA approved to BS1362.

If in doubt, consult a qualified electrician. Do not attempt any electrical repairs yourself.

CABLE EXTENSION.

Do not use an extension longer than 10 metres, with the conductor size at least the same size
as that on the machine.

DUST EXTRACTION

The sander is provided with a dust extraction facility, where a vacuum extractor may be
connected to the outlet at the rear of the machine. An adapter is provided for this purpose.
Please note however, that this does not preclude the user from wearing a face mask to
prevent the inhalation of dust particles.

It is an EEC requirement that a dust extraction facility be provided on power tools, however,
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

With the mains cable disconnected from the mains supply, select the abrasive paper
appropriate for the job in hand, and attach it to the Base Plate, by releasing the two spring
clips - one for each end.

Align the abrasive sheet so that the holes are perfectly aligned with those in the base plate,
and bend the ends over, securing at each end with the spring clip.

It is important that the abrasive sheet should be taught and not sag.

If required, attach the dust extractor adapter by pushing the end into the orifice at the rear
of the tool until it locks into place. The vacuum dust extractor may then be attached to it.

The ON/OFF trigger switch is located under the grip.

DO NOT plug in to the mains, unless you have ensured the tool is switched OFF. To do this,
pull the switch fully upwards, and then release it.

To switch the machine ON, pull the trigger switch and hold in position. A button lock is
provided on the side of the handle which may be used for prolonged use. Simply push it in
with the trigger pressed then release the trigger.

To release the switch lock, and switch OFF, pull the trigger switch a second time.

GENERAL HINTS FOR SANDING

Always use abrasive paper that is in top condition, worn paper will cause damage to the
base plate. Please note, that base plates are NOT covered by the warranty.

When starting, ALWAYS place the sander on the work BEFORE switching ON. This will prevent
the work from being badly scored, because if the tool is placed on the work after switching
on, it will be running at high speed, and almost impossible to place on the work smoothly
and evenly.

Move the machine evenly and smoothly over the surface of the work, with only light pressure,
evenly spread on the front hand post, and the handle. This helps to expel dust particles,
and produce an even finish, and will also prolong the life of the abrasive paper.

Let the machine do the work. Ensure the tool is flat on the work surface and DO NOT apply
excessive downwards pressure, as this will not only produce an uneven finish, but will overload
the motor causing it to burn out.

Be cautious when sanding off the end of a workpiece, as the paper could come off the
base plate, damaging the pad in the process.

MAINTENANCE

Always inspect the machine before use, and ensure it is in top condition.

Ensure all air vents are clear, (use compressed air to clean the machine where possible).

Check the cable to ensure it is sound and free from cracks, bare wires etc.

RENEWING THE BASE PLATE

Ensure the machine is disconnected from the mains supply, then unscrew the four screws
securing the plate to the machine.

Replace the plate and reassemble ensuring you DO NOT overtighten the four screws.

TROUBLE SHOOTING

Sander is overheating

This indicates the machine is dirty. Clean the ventilation holes, and blow
out with compressed air or a clean 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 the blows repeatedly, consult your CLARKE dealer.

VIBRATION EMISSIONS

Employers are advised to refer to the HSE publication “Guide for Employers”.

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 herz is potentially damaging and is
most hazardous in the range from about 5 to 20 herz.

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.

These tests produce a value‘a’, expressed in metres per second per second, which represents the average
vibration level of all tests taken, in three axes where necessary, and a second figure ‘K’, which represents
the uncertainty factor, i.e. a value in excess of ‘a’, to which the tool could vibrate under normal conditions.
These values appear in the specification panel below.

You will note that a third value is given in the specification - the highest measured reading in a single
plane. This is the maximum level of vibration measured during testing in one of the axes, and this should
also be taken into account when making a risk assessment.

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

The uncertainty factor should also be taken into account when
assessing a risk. The two figures ‘a’ and ‘K’may be added
together and the resulant value used to assess the risk.

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.
