GENERAL SAFETY RULES

1) 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 flamable liquids, gasses or dust. Power tools create sparks
which may ignite dust or fumes.

3. Keep children and bystanders away while operating a power tool. Distrac­tions can cause you to loose control.

2) ELECTRICAL SAFETY

1. Power tools must match the power outlet. Never modify the plug in any
way. Do not use adaptor plugs with earthed (grounded) power tools.

Correct plugs and outlets will reduce the risk of electric shock.

2. Do not expose power tools to rain or wet conditions. Any water entering
power tools will increase the risk of electric shock.

3. Do not abuse the electrical cable. Never use the cord for pulling or un-

plugging the power tool. Keep the cable away from sources of heat, oil,
sharp edges or moving parts. Damaged or tangled cables increase the

risk of electric shock.

4. When operating a power tool outdoors, use an extension cable suitable

for outdoor use. Using the correct cable reduces the risk of electric shock.

3) PERSONAL SAFETY

1. Stay alert, watch what you are doing and use common sense when you
are operating a power tool. Do not operate a power tool when you are

tired, ill or under the influence of alcohol, drugs or medication.

2. Wear personal protective equipment including eye protection. Safety
equipment such as a dust mask, non-skid shoes or hearing protection used
for appropriate conditions will reduce personal injuries. Use a face or dust
mask if operation is particularly dusty. Wear ear protectors/defenders as
the noise level of this machine can exceed 85dB (A).

3. Do not over-reach. Keep your proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.

4. Avoid accidental starting of the machine. Ensure the switch is in the off
position and the locking button disengaged before plugging the machine
in to the power supply. Carrying power tools around with your fiinger on
the trigger or plugging in power tools that are switched on invites acci­dents.

5. Remove any adjusting key or wrench before turning the power tool on. A
tool left attached to a moving part may result in personel injury.

4

6. Dress properly. Do not wear loose clothing or jewellery which may get
caught in moving parts. Wear protective hair covering to contain long
hair. For best footing, wear rubber soled footwear. Keep floor clear of oil,
scrap wood, etc.

7 Concentrate on the job in hand, no matter how trivial it may seem. Be

aware that accidents are caused by carelessness due to familiarity.

8. Switch the machine OFF immediately after the task is completed.

4) POWER TOOL USE AND CARE

1. Do not force the machine. Use the correct power tool for your application.
It will do a better and safer job at the rate for which it was designed.

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 power tool from the power supply before making any
adjustments, changing accessories, or storing the tool. These measures will
reduce the risk of the power tool starting accidently.

4. Store power tools out of the reach of children and do not allow persons
unfamiliar with these instructions to operate the power tool. Power tools
are potentially dangerous in the hands of untrained users.

5. Maintain power tools in top condition. Keep tools/ machines clean for the
best and safest performance. Check for misalignment or binding of
moving parts, broken parts, or any 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 recommended accessories. The use of improper accessories could be
hazardous.

7. Machine cleanliness. Do not allow the ventilation slots in the machine to
become blocked with dust.

8. Check the power tool for damage before using the machine. Any dam­aged part should be inspected 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 machine’s operation. Any damage should be properly repaired or
the part replaced. If in doubt, DO NOT use the machine. Consult your
local dealer.

5) SERVICE

1. When necessary, have your power tools serviced or repaired by a quali­fied person using identical replacement parts. This will ensure that the

safety of the power tool is maintained.

JIGSAW SAFETY INSTRUCTIONS

1. Only use the jigsaw in the manner and for the functions described in these
instructions.

2. Using the correct blade. Use the appropriate saw blade for the material
being cut. Different blades are available from your Clarke dealer.

3. Use of the mains cable. 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. Working on the bench. Allow sufficient clearance beneath the work to
ensure the blade does not come into contact with the floor, table etc.

5. Switching off. Never place the saw on a table or bench if it has not
completely stopped. The saw blade will continue to reciprocate for a
short time after the trigger has been released to stop the saw.

6. Cutting of pipes. Do not cut hollow pipe and do not cut material above
the specified thickness.

7. Cutting into walls. Do not cut through walls or cavities before checking for
hidden electrical wires or water pipes etc.

8. Finishing cutting. Do not remove tool from work until the blade has
completely stopped. Do not touch the blade immediately after use, allow
time for it to cool.

9. Use outdoor extension leads. If working outdoors, 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. We strongly recommend that this machine is connected to
the mains supply via a Residual Current Device (RCD).

10. Cutting sheet materials. 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.

11. Always hold the saw by its insulated handle. The saw’s metal parts may
become conductive if the blade should come into contact with the
mains cable.

12. Beware of foreign objects. When cutting pre-used wood, ensure all nails
have been removed beforehand. Nails will damage the wood saw blade.

13. Cooling agents. When cutting metals, always use a cooling agent i.e.
cutting/soluble oil.

14. Changing the blade. Be careful during adjustment of the machine to
prevent entrapment of the fingers between a moving blade and fixed
parts of the machine. Ensure the blade is fully tightened before use.

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

OPERATION

USING THE JIGSAW

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.

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

Ensure that the workpiece being cut is securely held in place and that the cut
line is clearly marked. Connect the vacuum extractor port to an extract
system wherever possible.

Place the sole-plate on the workpiece taking care that the saw blade is
vertical and correctly positioned in relation to the cut line without touching it.
Push the clear plastic blade guard down fully.

Ensure the saw blade is not striking on anything below the workpiece and
that the power cable is well away from the moving blade before starting the
saw. If cutting out an aperture, it will be necessary to drill a suitably sized hole
in the workpiece for use as a starting point.

down. Wait until the blade is running
at speed before attempting to cut the
workpiece. To stop the tool if the
switch lock is used, pull the trigger
switch fully in, then release it and the
motor will stop.

When starting, place the sole-plate on
the workpiece and let the blade

Trigger switch

touch the cut line. To make your cut,
pull the trigger and move the saw
slowly forward along the cutting line.

Take extra care when cutting curves - move the blade slowly to avoid stress
on the blade, leading to blade breakages. Never use a blade type which is
unsuitable for the type of material to be cut.

When sawing, hold the saw in front of you but do not put more pressure on
the blade than is necessary and avoid putting any lateral pressure on the
blade.

Let the blade work through the workpiece, ensuring the sole plate is flush with
the workpiece and the blade remains perpendicular to it.

CUTTING DIFFERENT MATERIALS

CUTTING WOOD

Check that any previously used timber being sawn does not contain any nails
or other metal objects which would damage the blade.

CUTTING METAL

Having chosen a suitable blade for cutting metal it is recommended to
lubricate the material and saw blade with cutting oil to prevent the tool from
overheating. Support the workpiece with wooden blocks on either side.

CUTTING PLASTIC

Having chosen a suitable blade for cutting plastic, make a test cut first to
determine that the material can tolerate the heat generated by sawing.

ADJUSTING THE SOLE-PLATE

The sole-plate is adjustable so that bevels of up to 45° may be cut. Loosen the
two screws under the sole-plate before adjusting it to the desired angle and
re-tightening the screws. However, if absolute accuracy is required you should
always check the angle with a protractor whilst carefully tightening the
securing screws. This includes setting the base plate for cutting at 90°, (check
roller is still only just touching blade).

DUST EXTRACTION

The jigsaw 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

CLEANING

• 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 if possible).

• After use, clean all dust and wood chippings from the jigsaw.

• Make sure that the base plate is free from dirt and grease.

• The blade locating clip and support roller should be kept clean and

lightly oiled at regular intervals.

• Keep the handle clean and free from oil and grease.

• Resin and glue on the blade causes poor cutting results. Clean the

blade after use.

GENERAL MAINTENANCE

• Ensure all nuts, bolts and screws remain tight to ensure the jigsaw is

in safe working condition.

• Refer to your CLARKE dealer if internal maintenance is required.

• 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.

11

• 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.

• Only use the replacement blades specified for this product (consult

your CLARKE dealer).

FAULT FINDING

JIGSAW 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.

JIGSAW 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 by replacing the
brushes or alternatively contact the Clarke Service department for their
replacement.

EXCESSIVE VIBRATION

Disconnect the mains lead and check that the blade is correctly fitted see
page 9. If the blade is damaged replace it with a new one.

If vibration persists, consult your local Clarke dealer, or contact the Clarke
Service department.

SPARE PARTS

VIBRATION EMISSIONS

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.

a’

These tests produce a value‘
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/s

2

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.
