WARNING

• Some dust created by power sanding, sawing, grinding, drilling and other construction activities contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
  • Lead from lead-based paints.
  • Crystalline silica from bricks, cement, and other masonry products.
  • 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.
  • Work with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
  • Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth or eyes or to lie on the skin may promote the absorption of harmful chemicals

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 increased 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 a 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 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 safely 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 and clothing 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 safely 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 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 behavior 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 (130°C) 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.

Direction-of-Rotation (Forward/Center-Lock/Reverse) Selector

WARNING After tool use, lock the direction-of-rotation selector in the “OFF” position (center-lock) to help prevent accidental starts and possible injury.

Your tool is equipped with a direction-of-rotation selector, located above the variable-speed trigger switch. This selector is used to change the direction of rotation of the bit and to lock the variable-speed trigger in the “OFF” (center-lock) position (Fig. 3).

• Position the direction-of-rotation selector to the far left of the tool for forward rotation to tighten bolts and nuts.
• Position the direction-of-rotation selector to the far right of the tool for reverse rotation to loosen bolts and nuts.
• Position the switch in the “OFF” (center-lock) position to help reduce the possibility of accidental starting when the tool is not in use.

NOTICE: To prevent gear damage, always allow the impact wrench to come to a complete stop before changing the direction of rotation.
NOTICE: The impact wrench will not run unless the direction-of-rotation selector is engaged fully to the left or to the right.

Variable-Speed Trigger Switch
Your tool is equipped with a variable-speed trigger switch. The tool can be turned “ON” or “OFF” by depressing or releasing the variablespeed trigger switch. The variable-speed trigger switch delivers higher speed with increased trigger pressure and lower speed with decreased trigger pressure (Fig. 4).

LED Light (Fig. 5)
Your tool is equipped with an LED light, located on the head of the tool. This provides additional light without shadows on the surface of the work piece for operation in lower-light areas.

To turn on the LED light:

• The LED light will automatically turn on with a slight squeeze on the variable-speed trigger switch before the tool starts running.
• The LED light could be turned on manually by pressing the LED light button. To turn off the LED light:
• The LED light could be turned off manually by pressing the LED light button after the variable speed trigger switch is released.

NOTICE: The LED light button is disabled when the motor is running. When the tool and/or battery pack becomes overloaded or too hot, the internal sensors will turn the tool off. If the tool and/or battery pack are overloaded, the LED light will flash rapidly. Rest the tool for a while or place the tool and battery pack separately under air flow to cool. The LED light will flash more slowly to indicate that the battery is at low-battery capacity. Recharge the battery pack.

Changing the Work Modes

When the tool is set in reverse rotation, the work mode – a combination of rotation speed, impact rate, and torque – can be changed toallow a loosening force suitable to the work at hand. Every time the mode button is pressed, the mode will toggle between 4 work modes:

• Low-Speed Mode – Indicator light above “1” shines green.
• Medium-Speed Mode – Indicator lights above “1” and “2” shine green.
• High-Speed Mode – Indicator lights above 1, 2, and 3 shine green.
• Reverse Control Mode – Indicator light corresponding to “RM” shines green.

In reverse control mode, the tool loosens a bolt or nut at high-speed first. Once the nut or bolt is completely loose, the tool will stop automatically to prevent the bolt or nut from falling out. The reverse control mode is available only when the tool is set is reverse rotation. If the tool is switched to forward rotation while in reverse control mode, the impact force and speed are the same as the high-speed mode “3”.

The modes can also be changed when the tool is set in forward rotation to allow a tightening force suitable to the work at hand.

NOTICE: The work mode can be changed only when any mode-indicator light is shining and the trigger switch is not depressed. The mode button is disabled when the motor is running. The work mode will be stored in memory and reactivated the next time the tool is turned on or when the direction of rotation has been changed. Reset the impact modes as desired. When the trigger is squeezed slightly or the mode button is pressed, any of the four indicator lights will automatically shine green, to indicate the work mode saved during the last use and will turn off approximately 60 seconds after the variable speed trigger switch is released. It means that during approximately one minute after releasing the switch trigger, the work mode can be changed.

To remove the Impact Socket:

• Simply pull the impact socket off from the square drive.

WARNING Wear protective gloves when removing the socket from the tool, or first allow the impact socket to cool down. The impact socket may be hot after prolonged use.

Tightening and Loosening Nuts and Bolts

To tighten nuts and bolts

Variable-speed control must be used with caution for driving nuts and bolts using socket set attachments. The best technique is to start slowly, increase speed as the nut or bolt runs down, and then set the nut or bolt snugly by slowing the tool to a stop. If this procedure is not followed, the tool will have a tendency to torque or twist in your hand when the nut or bolt seats.
a. Select hex socket that matches the nut or bolt. Then mount the socket onto the square drive, and fully grip the nut or bolt to be tightened with the hex socket.
b. Hold the tool firmly and apply just enough pressure to keep the socket engaged on the nut or bolt. Then press the trigger switch to impact the nut or bolt for several seconds.

NOTICE: Always use the correct size impact socket for bolts and nuts. An incorrect-size impact socket will result in inaccurate and inconsistent fastening torque and/or damage to the bolt or nut.
WARNING Do not over-tighten, as the force of the impact wrench can break the fastener. Hold the tool vertically with the bolt or nut, otherwise, the head of the bolt or nut will be damaged.

To loosen nuts and bolts

Use low-speed, medium-speed, high-speed or “control” mode to loosen nuts and bolts depending on the application. When working above ground or working on care tires, to prevent the loosened fasteners from falling to the ground or into a tight space, it is recommended to use the “control” mode to do this job.

• Select hex socket that matches the nut or bolt. Then mount the socket onto the square drive, and fully grip the nut or bolt to be loosened with the hex socket.
• Hold the tool firmly and apply just enough pressure to keep the socket engaged on the nut or bolt.
• Depress the variable-speed trigger switch to impact the nut or bolt. In control mode, once the fastener is fully loose, the tool will stop running. This tool also allows you to continue to depress the trigger switch for removing the nut from the long bolt, if necessary.
