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 20V HAMMER DRILL.

1) WORK AREA SAFETY

a. Keep work area clean and well lit. Cluttered or dark areas invite accidents.

b. 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.

c. Keep children and bystanders away while operating a power tool. Distractions

can cause you to lose control.

2) ELECTRICAL SAFETY

a. 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.

b. 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.

c. Do not expose power tools to rain or wet conditions. Water entering a power tool

will increase the risk of electric shock.

d. 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.

e. 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.

f. If operating a power tool in a damp location is unavoidable, use a residual

current device (RCD) protected supply. Use of an RCD reduces the risk of electric

shock.

3) PERSONAL SAFETY

a. 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.

b. Use personal protective equipment. Always wear eye protection. Protective

equipment such as dust mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce personal injuries.

Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]

c. Prevent unintentional starting. Ensure the switch is in the off-position before

connecting to power source and/or battery pack, picking up or carrying the
tool. Carrying power tools with your finger on the switch or energising power tools

that have the switch on invites accidents.

d. Remove any adjusting key or wrench before turning the power tool on. A wrench

or a key left attached to a rotating part o the power tool may result in personal
injury.

e. Do not overreach. Keep proper footing and balance at all times. This enables

better control of the power tool in unexpected situations.

f. 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.

g. If devices are provided for the connection of dust extraction and collection

facilities, ensure these are connected and properly used. Use of dust collection

can reduce dust-related hazards.

4) POWER TOOL USE AND CARE

a. 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.

b. 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.

c. Disconnect the plug from the power source and/or the battery pack from the

power tool before making any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce the risk of starting the

power tool accidentally.

d. 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.

e. Maintain power tools. Check for misalignment or binding of moving parts,

breakage of parts and any other 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.

f. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp

cutting edges are less likely to bind and are easier to control.

g. Use the power tool, accessories and tool bits etc. in accordance with these

instructions, 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.

5. BATTERY TOOL USE AND CARE

a. Recharge only with the charger specified by the manufacturer. A charger that is

suitable for one type of battery pack may create a risk of fire when used with
another battery pack.

b. Use power tools only with specifically designated battery packs. Use of any other

battery packs may create a risk of injury and fire.

4

Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]

c. When battery pack is not in use, keep it away from other metal objects, like

paper clips, coins, keys, nails, screws or other small metal objects, that can make
a connection from one terminal to another. Shorting the battery terminals
together may cause burns or a fire.

d. Under abusive conditions, liquid may be ejected from the battery; avoid

contact. If contact accidentally occurs, flush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected from the battery may cause
irritation or burns.

6) SERVICE

a. 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. Allow sufficient clearance beneath the work to ensure the drill bit does not
come into contact with the floor, table etc.

4. 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.

5. Do not drill into walls or cavities before checking for hidden electrical wires
or water pipes etc.

6. Do not touch the drill bit immediately after use, allow time for it to cool.

7. When drilling metals, always use a cooling agent i.e. cutting/soluble oil.

8. For your safety, do not connect the battery to your power tool until you
have read and understood this manual.

9. WEAR EYE PROTECTION. 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.

10. Wear ear protectors with impact drills. Exposure to noise can cause
hearing loss

11. DO NOT wear gloves, jewellery, neck ties or loose clothing.

12. DO NOT drill, cut or sand material tool small to be securely held.

13. ALWAYS keep hands out of the path of the drill bit.

14. Avoid awkward hand positions where a sudden slip could cause your hand
to move into the path of the drill bits.

15. SECURE THE 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.

16. MAKE SURE there are no nails or foreign objects in the part of the workpiece
to be drilled.

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 holes or driving screws into walls, floors etc., always

make sure that there are no live electrical wires in the path of the bit.

• 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.

• 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. NEVER force the drill bit into the work. This will overheat the
tip and cause it to dull very quickly.

• 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.

• When drilling in wood, clamp a piece of scrap wood to the

underside of the material to avoid splintering.

• Always drill directly in line with the bit. Do not use sideways

movement as this may damage the drill or cause the bit to break.

• Large holes should be drilled with wood augers, flat wood bits or

hole saws.

SCREWDRIVING TIPS

• Make sure that the screwdriver bit is inserted straight and upright in

the screw head, or the screw may be damaged.

• When driving wood screws, pre-drill pilot holes to make driving easier

and to prevent splitting the material.

• Select the forward direction to drive screws in and reverse direction

to take them out.

MAINTENANCE AND SERVICING

WARNING: ALWAYS REMEMBER TO POSITION THE DIRECTION CONTROL
SWITCH IN THE CENTRAL LOCKED OFF POSITION AND REMOVE THE
BATTERY PACK, BEFORE CLEANING THE DRILL.

• After use, remove the drill or screwdriver bit, open the chuck jaws

and tap the side of the chuck to remove any dust, or chippings etc.

• Keep the cooling vents clear.

• Clean the motor housing with a soft cloth.

• Keep the handle clean and free from oil and grease.

• Keep the charger clean and free from dust and grease.

• Worn or damaged parts must be replaced by qualified personnel.

• There are no user serviceable parts inside the drill.

REMOVING THE CHUCK

1. Open the jaws as far as possible.

2. Using a cross head screwdriver (inserted, down through the jaws), remove
the securing screw. The screw has a LEFT HAND THREAD and must therefore
be turned CLOCKWISE.

• Grasp the chuck and unscrew it from the drill in the normal manner,

i.e. by screwing it anticlockwise.
