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 main operated (corded) po we r to ol and ba tt e ry op er at e d (cordless) power tool.

SAVE THESE INSTRUCTIONS

Work Area Safety

1) Keep work area clean and well lit.

Cluttered or dark areas invite accidents.

2) Do not operate power tools in explo-

sive atmospheres, such as in the presence of flammable liquids, gases or dust.

Power tools create sparks which may ignite the dust or fumes.

Keep chil dren an d byst ander s 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 earthe d (groun de d) power tools.

Unm odif ied plu gs and mat chin g outlets will reduce risk of electric shock.

Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators.

There is an increased risk of electric shock if you r body is ear th ed or grounded.

Do not expose power tools to rain or wet conditions.

Wat er ente ring a po we r tool will increase the risk of electric shock.

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.

When operating a power tool out-

doors, use an extension cord suitable for outdoor use.

Use of a cord 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 personal injury.

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.

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 the power tools that have the switch on invites accidents.

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.

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

This enables better control of the power tool in unexpected situations.

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.

4 -

7) If device s are provide d 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.

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.

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.

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.

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.

Keep cutting tools sharp and clean.

Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

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.

Battery Tool Use and Care

1) Ensure the switch is in the off position before inserting battery pack.

Inserting battery pack into power tools that have the switch on invites accidents.

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.

3) Use power tools only with specifi-

cally designated battery packs.

Use of any other battery packs may create a risk of injury and fire.

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.

Under abusive conditions, liquid may be ejected from 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.

Service

1) Have your power tool serviced by a qualified repair person using only identical replacement parts.

This will ensure that the safety of power tool is maintained.

III

SPECIFIC SAFETY RULES

Hold power tools by insulated grip-

ping surfaces when performing an operation where the cutting tool may contact hidden wiring.

Contact with a “live” wire will make ex-

posed metal parts of the tool “live” and shock the operator.

5 -

2) Wear ear protectors. Exposure to

noise can cause hearing loss.

Be aware that this tool is always in an operating condition, since it does not have to be plugged into an electrical outlet.

4) If the bit becomes jammed, immediately turn the trigger switch off to prevent an overload which can damage the battery pack or motor. Use reverse motion to loosen jammed bits.

Do NOT operate the Forward/Reverse lever when the trigger switch is on. The battery will discharge rapidly and damage to the unit may occur.

When storing or carrying the tool, set the Forward/Reverse lever to the center position (switch lock).

Do not strain the tool by holding the speed control trigger halfway (speed control mode) so that the motor stops. The protection circuit will activate and may prevent speed control operation. If this happens, release the speed control trigger and squeeze again for normal operation.

8) Be careful not to get dust inside the chuck.

the same bolting material (e.g. steel), according to the surface finish.

Torque is greatly reduced when the

bolt and nut start turning together.

5) Socket play

Torque is lowered as the six-sided configuration of the socket of the wrong size is used to tighten a bolt.

6) Switch (Variable speed control trigger)

Torque is lowered if the unit is used

with the switch not fully depressed.

7) Effect of Connecting Adapter

The tightening torque will be lowered

through the use of a universal joint or a socket adapter.
