GENERAL SAFETY RULES
WORK AREA
1. Keep 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, gases or dust. Power tools create sparks
which may ignite the 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 tool plugs must match the outlet. Never modify the plug in any way.
Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded
3. Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase the risk of electric
shock.
5. When operating a power tool outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
WARNING: READ ALL INSTRUCTIONS. FAILURE TO FOLLOW ALL
INSTRUCTIONS LISTED MAY RESULT IN ELECTRIC SHOCK, FIRE AND/OR
SERIOUS INJURY. THE TERM “POWER TOOL” IN ALL OF THE WARNINGS
LISTED BELOW REFERS TO YOUR MAINS OPERATED (CORDED) POWER
TOOL OR BATTERY OPERATED (CORDLESS) POWER TOOL.

PERSONAL SAFETY
1. Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use a power tool while you are tired or
under the influence of drugs, alcohol or medication. A moment of
inattention while operating power tools may result in serious personal injury.
2. Use safety equipment. Always wear eye protection. Safety equipment such
as dust mask, non-skid safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal injuries.
3. Avoid accidental starting. Ensure the switch is in the off position before
plugging in. Carrying power tools with your finger on the switch or plugging
in power tools that have the switch on invites accidents.
4. Remove any adjusting key or wrench before turning the power tool on. A
wrench or a key left attached to a rotating part of the power tool may
result in personal injury.
5. Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jewellery. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewellery or
long hair can be caught in moving parts.
7. If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of these
devices can reduce dust related hazards.
POWER TOOL USE AND CARE
1. Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and safer 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 plug from the power source before making any
adjustments, changing accessories, or storing power tools. Such
preventative safety measures reduce the risk of starting the power tool
accidentally.
4. Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power
tool. Power tools are dangerous in the hands of untrained users.
5. Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tools
operation. If damaged, have the power tool repaired before use. Many
accidents are caused by poorly maintained power tools.

6. Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits etc., in accordance with
these instructions and in the manner intended for the particular type of
power tool, taking into account the working conditions and the work to be
performed. Use of the power tool for operations different from those
intended could result in a hazardous situation.
SERVICE
1. Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power
tool is maintained.
HAMMER DRILL SAFETY INSTRUCTIONS
1. Only use the 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
to the mains supply via a Residual Current Device (RCD).
9. Cooling agents. When drilling metals, always use a cooling agent i.e.
cutting/soluble oil.

periods of operation, wear safety shoes.
12. “Wear ear protectors with impact drills.Exposure to noise can cause
hearing loss”
13. DO NOT wear gloves, jewellery, neckties or loose clothing.
14. DO NOT drill material too small to be securely held.
15. ALWAYS keep hands out of the path of the drill bit. Avoid awkward hand
positions where a sudden slip could cause your hand to move into the path
of the drill bit.
16. SECURE WORKPIECE. Use clamps or a vice to hold the work when
practical.It is safer than using your hand and it frees both hands to operate
the tool.
17. MAKE SURE there are no nails or foreign objects in the part of the workpiece
to be drilled.
18. SDS Chuck for use with SDS Bits only.
19. Standard chuck should be used for normal (non hammer) drilling into
wood, metal or masonry
