GENERAL SAFETY RULES
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, 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 lose control.
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
unplugging 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. 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).
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. Concentrate on the job in hand, no matter how trivial it may seem. Be
aware that accidents are caused by carelessness due to familiarity.
4
Parts & Service: 020 8988 7400/E-mail:Parts@clarkeinternational.com or Service@clarkeinternational.com
5. 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.
6. 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 finger on
the trigger or plugging in power tools that are switched on invites
accidents.
7. Switch the machine OFF immediately after the task is completed.
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 accidentally.
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.
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.

RECIPROCATING SAW SAFETY INSTRUCTIONS
1. Only use the saw as described in these instructions.
CHANGING BLADES
2. Unplug the saw before changing blades, and take care to prevent
entrapment of the fingers between the blade and the shoe. Ensure the
blade is secure before use.
3. Use the appropriate saw blade for the material being cut. Different blades
are available from your Clarke dealer.
4. Only use saw blades in perfect working condition. Discard and replace
any cracked or bent saw blades.
WHEN SAWING
5. Use of the mains cable. Keep the mains cable well away from the saw
blade and ensure an adequate electrical supply is close at hand so that
the operation is not restricted by the length of the cable.
6. Working on the bench. Allow sufficient clearance beneath the work to
ensure the blade does not come into contact with the floor, bench etc.
7. 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.
8. Cutting of pipes. Do not cut hollow pipe and do not cut material above
the specified thickness.
9. Cutting into walls. Do not cut through walls or cavities before checking for
hidden electrical wires or water pipes etc.
10. Finishing cutting. Do not remove tool from work until the blade has
completely stopped and allow time for it to cool before touching the
blade immediately after use.
11. Use clamps & vices wherever possible. Use clamps and vices to secure
the workpiece.
12. 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.
13. Beware of foreign objects. When cutting pre-used wood, ensure all nails
have been removed beforehand. Nails will damage the wood saw blade.
14. Cooling agents. When cutting metals, always use a cooling agent i.e.
cutting/soluble oil.
15. Do not attempt to saw very small objects including those which cannot
be properly secured. Always hold the saw with both hands.
Please keep these instructions in a safe place for future reference.

OPERATION
IMPORTANT: DO NOT plug in to the mains, unless you have ensured the saw is
switched OFF. To do this, squeeze the trigger fully, then release it.
PRIOR TO CUTTING
1. Ensure that the workpiece is securely held in place and that the cut line is
clearly marked.
2. Ensure the 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.
• Let the blade work naturally. If cutting out an aperture, it will be necessary
to drill a suitably sized hole in the workpiece for use as a starting point.
• The blade should emerge from the workpiece at every point of the cut.
3. Check that any previously used timber being sawn does not contain any
nails or other metal objects which would damage the blade.
STARTING & STOPPING
1. To start the saw, squeeze the trigger.
2. Maintain the saw at a constant speed by pressing in the lock button.
• You can then release your finger pressure on the trigger.
3. To stop the saw if the lock button is used, squeeze the trigger fully in, then
release it and the motor will stop. Always switch off before unplugging.
USING THE SAW
CAUTION: ALWAYS KEEP YOUR HANDS AND FINGERS AWAY FROM THE
SHOE LOCKING BUTTON WHEN USING YOUR SAW. DEPRESSING THE
LOCK BUTTON DURING USE MAY RESULT IN THE SHOE BECOMING
UNLOCKED AND MOVING DURING USE.
1. Place the shoe against the workpiece and squeeze the trigger to run the
saw before letting the blade touch
the cut line on the work. To make
Fig 4
your cut, move the saw slowly
forward along the cutting line.
2. Take care not to allow the saw to
bounce on the workpiece. Ensure
the shoe remains in contact with the
workpiece.
3. Always hold the saw with both
hands on the body and handle.
10
Parts & Service: 020 8988 7400/E-mail:Parts@clarkeinternational.com or Service@clarkeinternational.com
4. Take extra care when cutting curves - move slowly to avoid stress on the
blade.
5. Avoid putting unnecessary pressure on the blade and avoid applying
lateral pressure. Let the blade work naturally.
6. Never try to start the tool if the blade becomes jammed in the workpiece.
7. If the blade becomes blunt in one section of its cutting edge, reposition
the shoe to utilise a sharper, unused portion of the blade. Fig 3 shows the
adjustable shoe which can be positioned close to the blade holder and
then extended to optimise the use of the blades & extend their useful life.
CUTTING DIFFERENT MATERIALS
Adjust the speed controller to suit the material being cut using the following
suggested settings as a starting point. However, the optimum speed will be
determined with practice.

CUTTING WOOD
PLUNGE CUTTING IN WOOD
• Rest the saw shoe on the workpiece in
such a position that the blade forms an appropriate angle for the plunge
cut.
• Switch the tool on and slowly feed in the blade. Make sure that the saw
shoe remains in contact with the workpiece at all times.
POCKET CUTS IN WOOD
• Measure and mark out the pocket cut. Using a narrow blade, rest the
bottom of the shoe on the workpiece ensuring the blade is on the cutting
line. If necessary, e.g. in confined spaces, use the outer edge of the saw
shoe as your guideline.
CUTTING METAL
1. Choose the correct blade for cutting metal. Support the workpiece with
wooden blocks on either side.
2. Apply a thin film of lubricant along the cutting line to prevent the tool from
overheating.
CUTTING PLASTCS
• Always work at reduced speed and carry out a test cut to see if the
material is sensitive to heat.

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 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.
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.
MODEL No:
CON850
DESCRIPTION:
RECIPROCATING SAW
Declared vibration emission value in accordance
with EN12096
Measured vibration emission value - a: 14 m/s2
Uncertainty value - K: 1.5 m/s2
Values determined according to EN28622-1
17
Parts & Service: 020 8988 7400/E-mail:Parts@clarkeinternational.com or Service@clarkeinternational.com
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.
