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. When operating a power tool outdoors, use an extension cable suitable for
outdoor use. Using the correct cable reduces the risk of electric shock.
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 trigger lock button disengaged before plugging the
machine in to the power supply. Carrying power tools around with your
4
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com
finger on the trigger or plugging in power tools that are switched on invites
accidents.
5. Dress properly. Do not wear loose clothing or jewelry 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. Concentrate on the job in hand, no matter how trivial it may seem. Be
aware that accidents are caused by carelessness due to familiarity.
7. Switch the machine OFF immediately after the task is completed.

HAMMER DRILL SAFETY INSTRUCTIONS
1. Only use the hammer drill in the manner and for the functions described in
these instructions.
2. Using the correct bit. Use the appropriate drill bit for the material being
drilled. Different bits are available from your Clarke dealer.
3. Use of the mains cable. Keep the mains cable well away from the drill 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 drill bit does not come into contact with the floor, table etc.
5. Switching off. Never place the drill on a table or bench if it has not
completely stopped. The drill bit will continue to rotate for a short time after
the trigger has been released to stop the drill.
6. Drilling into walls. Do not drill into walls or cavities before checking for
hidden electrical wires or water pipes etc.
7. Finishing drilling. Do not touch the drill bit immediately after use. Allow time
for it to cool.
8. 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

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: CON1200
DESCRIPTION: 1200W HAMMER DRILL
Declared vibration emission value in accordance with EN12096
Measured vibration emission value - a:16.7m/s
Values determined according to EN28622-1
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.
2
‘a’ values in excess of 2.5 m/s
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com
are considered hazardous when used for
17
2
prolonged periods. A tool with a vibration value of 2.8 m/s2 may be used for up
2
to 8 hours (cumulative) per day, whereas a tool with a value of 11.2 m/s
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.
