SAFETY PRECAUTIONS

WARNING: READ ALL INSTRUCTIONS. FAILURE TO FOLLOW ALL INSTRUCTIONS LISTED BELOW MAY RESULT IN ELECTRIC SHOCK, FIRE AND/ OR SERIOUS INJURY. THE TERM “POWER TOOL” IN ALL WARNINGS LISTED BELOW REFERS TO YOUR HAMMER DRILL.

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, 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 cable. Never use the cable for carrying, pulling or
unplugging the power tool. Keep cable 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 cable suitable for outdoor use. Use of a cable suitable for outdoor use reduces the risk of electric shock.

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. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
3
3. Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes or hearing protection used for appropriate conditions will reduce personal injuries.
4. 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.
5. 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.
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 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 battery before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
4. Store idle 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. Poorly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
7. Use the power tool and accessories 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 intended could result in a hazardous situation.

SERVICING

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. Use the appropriate drill bit for the material being drilled. Different bits are available from your Clarke dealer.
3. 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. Allow sufficient clearance beneath the work to ensure the drill bit does not come into contact with the floor, table etc.
5. 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. Do not drill into walls or cavities before checking for hidden electrical wires or water pipes etc.
7. Do not touch the drill bit immediately after use, allow time for it to cool.
8. 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. When drilling metal, always use a cooling agent i.e. cutting/soluble oil.
10. Use face or dust mask along with safety goggles if operation is dusty. Use hearing protection, particularly during extended periods of operation, wear safety shoes.
11. Wear ear protectors with impact drills. Exposure to noise can cause hearing loss.
12. DO NOT wear gloves, jewellery, neckties or loose clothing.
13. DO NOT drill material too small to be securely held.
14. ALWAYS keep your 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.
5
15. 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 drill.
16. MAKE SURE there are no nails or foreign objects in the part of the workpiece to be drilled.
17. The SDS Chuck is for use with SDS Bits only.
18. The standard chuck should be used for normal (non hammer) drilling into wood, metal or masonry.

11

DRILLING TIPS

• Always use sharp, good quality drill bits. The performance of your drill is dependant on the quality of the bits used.
• After drilling material to the full depth, do not simply pull out the drill but maintain chuck rotation to ease withdrawal.
• Reduce the pressure on the drill bit when it is about to break through. This will prevent the drill from jamming.
• If drilling a large hole, first drill a pilot hole using a smaller drill bit.
• Always apply pressure to your drill bit in a straight line and, where possible, at right angles to the workpiece.
• When drilling in metal, the materials being drilled can become hot. To reduce overheating use a suitable cooling lubricant. No cooling lubricant is necessary when drilling cast iron or brass as they should be drilled dry.
• When drilling metal, the harder the metal the slower the drill speed. Similarly, the bigger the drill bit the slower the speed.
• To prevent the drill bit from slipping when starting to drill a hole in metal, use a centre punch to make an indentation at the start point.
• Always start drilling at a slow speed to prevent the drill from slipping out of the pop mark or indent, gradually increasing speed until the optimum cutting speed is achieved whilst maintaining a MODERATE pressure ONLY. NEVER force the drill bit into the work. This will overheat the tip and cause it to dull very quickly.
• When drilling in wood, clamp a piece of scrap wood to the underside of the material to avoid splintering.
• Large holes should be drilled with wood augers, flat wood bits or hole saws.
