General Power Tool Safety Warnings

WARNING

Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed

below may result in electric shock, fire and/or serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work area safety

Keep work area clean and well lit.

Cluttered or dark areas invite accidents.

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.

Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

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.

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.

Do not expose power tools to rain or wet conditions. Water entering a power 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 outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

If operating a power tool in a damp location is unavoidable, use a Ground Fault Circuit Interrupter (GFCI) protected supply. Use of an GFCI reduces the risk of electric shock.

Personal safety

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

General Power Tool Safety Warnings

of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

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.

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 energizing 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 jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.

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.

Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

▶ Power tool use and care

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 remove the battery pack, if detachable, 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 and accessories. 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.

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, 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.

Keep handles and grasping surfaces dry, clean and free from oil and grease.

Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

▶ Battery tool use and care

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.

Use power tools only with specifically 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

General Power Tool Safety Warnings

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 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.

Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.

Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 265 °F may cause explosion.

Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

▶ Service

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.

Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

Safety Rules for Cordless Impact Wrenches

Hold the power tool by insulated gripping surfaces, when performing an operation where the fastener may contact hidden wiring. Fasteners contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

Brace the tool properly before use. This tool produces a high output torque and without properly bracing the tool during operation, loss of control may occur resulting in personal injury.

Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.

Do not drill, fasten or break into existing walls or other blind areas where electrical wiring may exist. If this situation is unavoidable, disconnect all fuses or circuit breakers feeding this worksite.

Always wear safety goggles or eye protection when using this tool.

Wear ear protectors when using the tool for extended periods. Prolonged exposure to high intensity noise can cause hearing loss.

Use thick cushioned gloves and limit the exposure time by taking frequent rest periods. Vibration caused by hammer-drill action may be harmful to your hands and arms.

Secure the material being fastened. Never hold it in your hand or across your legs. Unstable support can cause loss of control and injury.

Avoid accidental starting. Be sure the forward/reverse switch is in the off position before inserting battery pack.

Carrying appliances with your finger on the switch or inserting the battery pack into an appliance with the switch on invites accidents.

Remove battery pack before changing accessories. Accidental starting may occur because battery appliances with a battery inserted are in the operative condition.

Be prepared for a reaction torque when “seating” or removing a fastener. The screwdriver housing may tend to twist in the opposite direction of bit rotation when “seating” or removing a fastener depending on the torque setting of the tool.

Do not use dull or damaged impact

Safety Rules for Cordless Impact Wrenches

sockets and accessories. When installing an accessory, insert the impact socket well onto the output drive. Be sure the output drive has locked onto the socket correctly.

Do not run the tool while carrying it at your side. A spinning bit could become entangled with clothing and injury may result.

Place the tool onto the fastener only when the screwdriver is switched off. Rotating driver tools can slide off the fastener.

Do not use this tool as a drill. Tools

equipped with shut-off clutches are not designed for drilling applications. The output drive can shut off automatically and without warning.

Be careful when driving long screws – there is a risk of sliding off the fastener head depending on type of socket or bit used. First test the run-down of a fastener and pay attention during the screw driving process to ensure you do not injure yourself if the tool bit or socket slides off of the fastener.

Additional Safety Warnings

GFCI and personal protection devices like electrician's rubber gloves and footwear will further enhance your personal safety.

Do not use AC only rated tools with a DC power supply. While the tool may appear to work, the electrical components of the AC rated tool are likely to fail and create a hazard to the operator.

Keep handles dry, clean and free from oil and grease. Slippery hands cannot safely control the power tool.

Develop a periodic maintenance schedule for your tool. When cleaning a tool be careful not to disassemble any portion of the tool since internal wires may be misplaced or pinched or safety guard return springs may be improperly mounted.

Certain cleaning agents such as gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts.

Ensure the switch is in the off position before inserting battery pack. Inserting the battery pack into power tools that have the switch on invites accidents.

WARNING

Some dust created by power sanding, sawing,

grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

forward and simply remove it from the chuck.

VARIABLE SPEED CONTROLLED

TRIGGER SWITCH

Your tool is equipped with a variable speed trigger switch. The tool can be turned "ON" or "OFF" by squeezing or releasing the trigger. The speed can be adjusted from the minimum to maximum nameplate RPM by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed (Fig. 1).

FORWARD/REVERSING

After tool use, lock trigger in "OFF" position

to help prevent accidental starts and accidental discharge.

Your tool is equipped with a forward/reversing lever and trigger lock located above the trigger (Fig. 5). This lever was designed for changing rotation of the bit, and for locking the trigger in an "OFF" position.

For forward rotation, (with tool pointed away from you) move the lever to the far left.

For reverse rotation move the lever to the far right. To activate trigger lock move lever to the center off position.

CAUTION

Do not change direction of rotation

until the tool comes to a complete stop.

Shifting during rotation of the tool can cause damage to the tool.

BUILT IN WORK LIGHT

Your tool is also equipped with a light that turns on automatically when the switch is activated, for better visibility when driving (Fig. 1).

Operating Instructions

Operating Tips

INSTALLING FASTENERS

To fasten: Start the fastener by hand on to or in to its threaded counter part (E.G. nut on to bolt, bolt in to nut or threaded hole).

Next, with the proper impact socket securely mounted to the wrench, slide the impact socket on to the nut or bolt head. Hold the tool securely with both hands and squeeze the trigger switch. The impact socket will turn the fastener and impacting will begin once the fastener encounters resistance. See the following chart to estimate the amount of impact time required to obtain a desired torque.

To loosen: With the proper impact socket securely mounted to the wrench, slide the impact socket on to the bolt head. (be sure the rotational direction is “reverse”).

Hold the tool securely with both hands and squeeze the trigger switch. The tool will start to impact immediately. Once the fastener has "broken loose" it will start to unthread. Be careful that you do not allow a fastener to spin freely once it is no longer engaged with the other threaded part as it may be thrown out of the socket.

TIGHTENING TORQUE

The tightening torque depends on the duration of the impacting/tightening action. The largest tightening torque is achieved after approx. 6 to 10 Sec. impacting/tightening action.

The torque build-up depends on the following factors:

• Hardness of the bolts/nuts.
• Type of washer (disk washer, spring washer, seal).
• Hardness of the material to be joined.
• Lubricating effect at the surfaces of the junction.

This leads to the following application cases:

Hard case: The joining of metal to metal with a disk washer. The maximum torque is reached after a relative short impacting/tightening action.

Medium case: The joining of metal to metal where spring ring washer, disk spring washer, stud bolts or bolts/nuts with conical seats are used.

Soft case: The joining of e.g. metal to wood or insulation material.

For middle or soft joining cases, the maximum tightening torque is less as for hard cases. Therefore, a longer impacting/tightening action is necessary to arrive at the maximum tightening torque.

COLD WEATHER USE (32°F)

Due to the lubrication used in the impacting mechanism, the tool should be run for three minutes at no load prior to actual usage. This will warm the lubricant and provide better performance.

INSERTING AND RELEASING BATTERY PACK

Set Forward/Reversing lever to the center (off position). Slide charged battery pack into the housing until the battery pack locks into position (Fig. 6)

Your tool is equipped with a secondary locking latch to prevent the battery pack from completely falling out of the handle, should it become loose due to vibration.

To remove the battery pack, press the battery pack release button and slide the battery pack forward.

Press the battery pack release button again and slide the battery pack completely out of tool housing (Fig. 6).
