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 any 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 cable 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.

5. Avoid accidental starting of the machine. Ensure the switch is in the off
position before plugging the machine in to the power supply. Plugging in
power tools that are switched on invites accidents.
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. Wear gloves while handling saw blades and always store them in the
protective packing provided. A dust mask should be warn to reduce the
inhalation of harmful dust.
8. Always remove and stack cut timber in a suitable place, away from the
operator.
9. Switch the machine OFF immediately after the task is completed.
POWER TOOL USE AND CARE
1. Do not force the machine. Use the correct 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 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 this product. Power tools are
potentially dangerous in the hands of untrained users.
5. Maintain power tools in top condition. Keep 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 tool’s operation.
If damaged, have the tool repaired before use. Many accidents are
caused by poorly maintained power tools.
6. Machine cleanliness. Do not allow the ventilation slots in the motor to
become blocked with dust.
7. Check the power tool for damage before use. Any damaged part should
be inspected to ensure that it will operate properly and perform its
intended function. Any damage should be properly repaired or the part
replaced. If in doubt, DO NOT use the machine. Consult your local dealer.
SERVICING
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.

PRECAUTIONS SPECIFIC TO CIRCULAR SAWS
1. ALWAYS wear ear protectors/defenders during continuous use as the noise
level of this machine can exceed 85dB (A).
2. ALWAYS keep the mains cable well away from the saw and ensure an
adequate electrical supply is close at hand so that the operation is not
restricted by the length of the cable.
3. ALWAYS use only the correct blade for this saw and ensure the blade is
fully tightened before use. The blade must always be rated to operate at
a rotational speed equal to, or greater than that of the machine.
4. Beware of foreign objects. When cutting pre-used wood, ensure all nails
have been removed beforehand. Nails will damage the saw blade.
5. Switching off. Remember that the blade will continue to rotate for a short
time after the stop button has been pressed to stop the saw.
6. NEVER operate the saw when the moving blade guard is not working
properly. The guard should be checked for correct operation before
each use. It must move freely and readily return to the starting position.
7. NEVER operate the saw without the removable blade guard being
installed correctly.
8. NEVER start the saw when the blade is in contact with the work.
9. DO NOT use the saw if the power cable, plug or motor is in poor condition.
10. ALWAYS hold the workpiece securely when cutting. The workpiece should
always be placed securely in the log cradle to avoid loss of control.
11. ALWAYS hold the cradle handles with both hands to keep hands well away
from the saw blade.
12. Do not attempt to saw very small logs including those which cannot be
properly secured.
CHANGING BLADES
1. Unplug the saw from the power supply before changing blades, and take
care to prevent entrapment of the fingers between the blade and the
inner guard. Ensure the blade is secure before use.
2. Use the appropriate saw blade for this saw. Correct blades are available
from your Clarke dealer, (part number 3401992).
3. Only use saw blades in good working condition. Discard and replace
cracked or bent saw blades.
Please keep these instructions in a safe place for future reference.
