General safety rules

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 of the warnings listed below refers to your mains operated

(corded) power tool or battery operated (cordless) power tool.

Save these instructions

1. Work area a. Keep work area clean and well lit.

Cluttered and 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.

4

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 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.

c. 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.

d. 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.

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 these devices 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 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 tools 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 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.

5. 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.

1. To select the low speed, high torque setting (Position 1), turn the tool off and let the motor come to a complete standstill. Turn the gear selector to Position “1”.

2. To select the high speed, low torque setting, (Position 2), turn the tool off and let the motor come to a complete standstill. Turn the gear selector to Position “2”.

NOTE . Do not change gears when the drill motor is turning.

If you are having trouble changing gears, make sure that the gear selector is either completely in Position 1 or completely in Position 2 as you rotate the chuck by hand.

Chuck replacement

Always wear eye protection.

Chuck removal

The chucks of reversible drills are always fixed by a screw with left-hand thread. The screw, which is located in the centre of the chuck, must be removed before the chuck can be removed.

1. Tighten the chuck around the shorter end of a hex key

(not supplied) of 1/4” or greater size. Using a wooden mallet or similar object, strike the longer end in the clockwise direction. This will loosen the screw inside the chuck.

2. Open chuck jaws fully.

3. Insert a screwdriver into front of chuck between jaws to engage screw head. Remove screw by turning clockwise.

4. Place a hex key in chuck and tighten. Using a wooden mallet or similar object, strike key sharply in the counterclockwise direction.

This will loosen the chuck so that it can be unscrewed by hand.

Chuck installation

1. Screw the chuck on by hand as far as it will go and insert screw (LH thread).

2. Tighten the chuck around the shorter end of a 1/4” or large hex key (not supplied) strike the longer end in the clockwise direction with a wooden mallet.

3. Remove the hex key and open the jaws fully. Tighten the screw in the centre of the chuck firmly.

Hints for use

NOTE. When drilling into masonry the drilling rate is fast and burnout of the tip will occur if the drill bit is not constantly cleared.

• Use only correctly sharpened drill bits, which are suitable for the material being drilled.

• To drill hard materials, firm pressure is required on the power tool. However, excessive pressure does not improve performance and places unnecessary pressure on the tool and its bit.

• When screw driving always use a pilot hole and set the speed dial to low. Press firmly on the screw head and pull the trigger gradually increasing the speed. It is always wiser to test the screw driving on a scrap piece of the same material you are using.

• Larger diameter holes in hard wood, steel and concrete have to be drilled at slower speeds. However, the motor must not be struggling with the operation. If the motor is struggling DO NOT continue working, pull the drill clear of the workpiece and run it on fast speed for a minute or so allowing the motor time to cool down before you attempt a little more of the work. If the job is too hard for the drill do not continue otherwise permanent damage to the motor will occur.

• Wire brushing or sanding should be carried out on the highest speed.

• Concrete drilling should be carried out on the highest speed.

DO NOT overload motor when drilling concrete.

DO NOT use too much pressure as the hammer action relies on the drill bit being able to move back and forward in the hole being drilled.

Always clear the flutes of the drill bit by removing it from the hole regularly.

Wood drilling

• For maximum performance, use high speed steel bits for wood drilling.

• Move drilling mode selector to drilling mode .

• Secure the workpiece to prevent it from turning when drilling.

• Begin drilling at a very low speed to prevent the bit from slipping off the starting point. Increase the speed as the drill bit bites into the material.

• When drilling through holes, place a block of wood behind the workpiece to prevent ragged or splintered edges on the back side of the hole.

• Do not lock the trigger in the ‘on’ position when the drill may need to be stopped suddenly.

Metal drilling

• For maximum performance, use high speed steel bits for metal or steel drilling.

• Move drilling mode selector to drilling mode .

• Use a centre punch to mark the hole location on the workpiece.

• Begin drilling at a very low speed to prevent the bit from slipping off the starting point.

• Maintain a speed and pressure which allows cutting without overheating the bit. Applying too much pressure will:

- Overheat the drill

- Wear the bearings

- Bend or burn bits

- Produce off-centre or irregular shaped holes

• When drilling large holes in metal it is recommended to drill with a small bit at first, then finish with a larger bit.

Also, lubricate the bit with oil to improve drilling action and increase bit life.

11

Masonry drilling

• For maximum performance use tungsten carbide-tipped masonry impact bits when drilling holes in brick, tile, concrete, etc.

• Move drilling mode selector to hammer mode .

• Apply light pressure and medium speed for best results in brick.

• Apply additional pressure and high speed for hard materials such as concrete.

• When drilling in tile, practice on a scrap piece to determine the best speed and pressure.

Cleaning

1. Keep your machine and its cord clean. The outside of the machine can be cleaned using a damp soft cloth with a mild detergent if required.

2. Some maintenance products and solvents may damage the plastic parts; these include products containing benzene, trichloroethylene, chloride and ammonia.

3. Excessive sparking generally indicates the presence of dirt in the motor or abnormal wear on the carbon brushes.

4. Take special care to keep the ventilation inlets/outlets free from obstruction; cleaning with a soft brush followed by a compressed air jet will usually be sufficient to ensure acceptable internal cleanliness.

5. Wear eye protection when carrying out cleaning.

CAUTION. Do not use cleaning agents to clean the plastic parts of the drill.

Power cord maintenance

If the supply cord needs replacing, the task must be carried out by the manufacturer, the manufacturer’s agent, or an authorised service centre in order to avoid a safety hazard.
