This Product Conforms To 98/37/EEC Regulations

When disposing of this product, ensure it is disposed of according to all local ordinances. It must
not be disposed of with general household waste.

Please note that the details and specifications contained herein, are correct at the time of going to print. However,

CLARKE International reserve the right to change specifications at any time without prior notice.

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 below 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 resultant 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.

Vibration Emissions

Safety Precautions

HAND-ARM VIBRATION

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.

Additional Precautions For Jig Saws

1. ALWAY S wear ear protectors/defenders as the noise level of this machine can exceed

85dB (A).

2. ALWAY S use the appropriate saw blade for the material being cut.

3. ALWAY S keep the mains cable well away from the machine and ensure an adequate

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

4. ALWAY S switch the machine OFF immediately the task is completed.

5. ALWAY S ensure the blade is fully tightened before use.

6. ALWAY S allow sufficient clearance beneath the work to ensure the blade does not

come into contact with the floor, table etc.

7. NEVER allow the ventilation slots in the machine to become blocked.

8. DO NOT cut hollow pipe and do not cut material above the specified thickness.

9. DO NOT cut through walls or cavities before checking for hidden electrical wires or

water pipes etc.

10. DO NOT remove tool from work until the blade has completely stopped.

11. DO NOT touch the blade immediately after use, allow time for it to cool.

12. DO NOT cut work less than at least twice the pitch of the saw blade. i.e. at least two

teeth must be in contact with the work at all times.

13. DO NOT use the machine if the electric cable, plug or motor is in poor condition.

14. When cutting wood, ensure all nails have been removed beforehand. Nails will damage

the wood saw blade.

15. When cutting metals, always use a cooling agent i.e. cutting/soluble oil.

16. Replacement blades for wood, plastic and steel are available from your CLARKE dealer.

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 Double 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 Clarke 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.

Always use an approved cable extension suitable for the power rating of this tool (see
specifications), the conductor size should also be at least the same size as that on the

machine, or larger. When using a cable reel, always unwind the cable completely.

Changing Blades

Note :

Item numbers in brackets, refer to parts list on page 8.

With the power cable disconnected from the mains supply, slacken off the two hex
socket screws, (item 33), securing the Base Plate, using the hex. wrench stored at the rear
of the base of the tool, and ease the roller, (item 36), backwards away from the blade.

Loosen the two blade holder screws, (item 22), (accessed through the clear plastic blade
guard) and remove existing blade. Select the saw blade appropriate for the job in hand,
and insert it in to the Blade Holder as far as it will go, with the teeth facing forwards.

Tighten the two blade holder Hex socket screws progressively, until the blade is held firmly.

Push the roller forwards so that it just touches the back of the blade, and with the base
plate at the desired angle (this will normally be at 90°), tighten the two base plate
securing screws.

Operation

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

IMPORTANT: 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.

Push the clear plastic blade guard down fully.

To start the tool pull the trigger switch. Blade speed is dependant upon the pressure
applied to the trigger. The greater the pressure (ie the more it is pulled in) the greater the
speed. If you desire a constant speed, pull the switch all the way in and lock in position
with the knob on the side of the grip, then adjust the blade speed by turning the knob
(within the trigger switch) until you achieve the desired result. Wait until the blade is
running at its desired speed before attempting to cut the workpiece. To stop the tool if
the switch lock is activated, pull the trigger switch fully in, then release it, (motor will stop).

to make a cut, depress trigger, place the end of the base plate on the workpiece and
move it slowly forward along the cutting line. Take extra care when cutting curves - move
the blade slowly to avoid stress and therefore blade breakages.

The base plate is adjustable so that bevels of 15°, 30°,45° may be cut, however, if absolute
accuracy is required you should always check the angle with a protractor whilst carefully
tightening the two base plate securing screws. This includes setting the base plate for cutting
at 90°, (check roller is still only just touching blade).

Trouble Shooting

Jig Saw 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.

Jig Saw 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.

DUST EXTRACTION

The Jig saw is provided with a dust extraction facility, where a dust bag or vacuum extractor
may be connected to the rear of the machine. 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.

Maintenance

Always inspect the tool 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 power cable to ensure it is sound and free from cracks, bare wires etc. avoid
using solvents when cleaning plastic parts, most plastics are susceptible to damage from
the various types of commercial solvents.

All bearings etc, in this tool are lubricated with a sufficient amount of high grade lubricant
for the tools lifetime under normal operating conditions, therefore no further lubrication is
required.
