SPECIFIC SAFETY

WARNING:  DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to the tool safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.

1. Use the correct tool for the job. This tool was designed for a specific function. Do not modify or alter this tool or use it for an unintended purpose.
2. Always disconnect the impact wrench from the power supply before opening the belt guard cover. Make sure the belt guard cover is closed before reconnecting the tool to the power supply.
3. Always hold the tool firmly in your hands before switching the tool ON. The reaction to the motor’s torque may cause the tool to twist, as it accelerates to full speed.
4. Never attempt to change the impact socket’s direction of rotation while it is active. This can damage the interlock feature built into the switch. Be sure the impact socket has completely stopped and engage any safety features before changing the rotation direction. Turn the power off as an added precaution.
5. Clean the impact wrench’s air vents often. The motor’s fan will draw dust and other particulates into the tool. Excessive accumulation of wood, plastic or metal particulates can create a fire or electrical hazard.
6. Inspect the tool components periodically. Repair or replace damaged or worn components. Only use identical replacement parts when servicing.

PRECAUTIONS

POWER TOOL PRECAUTIONS

1. Do not use any power tool with a malfunctioning power switch or control. A power tool that fails to respond to the controls is dangerous and can cause an injury. A qualified technician must repair and verify the power tool is operating correctly, before it can be used.
2. Shut the power off and disconnect the impact wrench from the power supply (if possible) before making any adjustments, changing accessories, cleaning, servicing or when storing. Such preventive safety measures reduce the risk of starting the tool accidentally.
3. Never force the tool. Excessive pressure could damage to the tool, your workpiece or cause serious personal injury. If the impact wrench runs smoothly under no load, but does not run smoothly under load, then excessive pressure is being used.
4. Check if the impact wrench’s moving parts are misaligned or binding before each use. Correct the issue before using the impact wrench to avoid an injury or damage to the tool.
5. Always be aware of the position of your hands relative to the impact wrench. Avoid awkward hand positions where a sudden slip could cause a hand to move into the impact socket. Never reach behind or beneath the impact wrench.
6. Only use accessories that are specifically designed for use with the impact wrench. Ensure the impact socket is tightly installed.
7. Only use an impact socket that exceeds the Speed rating (see Specifications).
8. Before using the impact wrench on a workpiece, test the impact wrench by running it at the highest speed rating for at least 30 seconds in a safe position. Stop immediately if there is any abnormal vibration or wobbling. Check the tool to determine the cause.
9. Never touch the impact socket or workpiece during or immediately after use. They may be hot and could inflict a burn injury.
10. Do not cover the air vents. Proper cooling of the motor is necessary to ensure normal life of the tool.
11. Never use a tool with an impact socket that is cracked or worn. Change the impact socket before using it.
12. Do not place the impact wrench down until the impact socket has stopped moving. The impact wrench may catch the surface of work material and wrench itself free, causing injury to the user or others in the work area.
13. Never point the impact wrench towards yourself. It could inflict an injury.

KICKBACK PRECAUTIONS

Kickback is a sudden reaction when the impact wrench snags or is caught on the material. If kickback occurs:

• The impact socket may pass over a body part, causing an injury.
• The tool may strike bystanders.
• Kickback can also damage the tool or workpiece.

Kickback can be avoided by taking proper precautions:

1. Maintain a firm grip on the tool and position your body and arms to allow you to resist a kickback. Kickback will propel the tool in the direction opposite the impact socket’s direction of rotation. The tool may pull out of your grasp.
   • Use clamps or a vice to hold down smaller workpieces.
2. Only use an impact socket designed for the tool.

ELECTRICAL SAFETY

WARNING:  Do not touch or handle a live tool with any part of your body that is wet or damp. Wet skin reduces resistance to electrical current, increasing the danger of a serious or fatal shock.

1. Do not alter any parts of the tool or accessories. All parts and accessories are designed with built-in safety features that may be compromised if altered.
2. Protect yourself against electric shocks when working on electrical equipment. Avoid body contact with grounded surfaces. There is an increased chance of electrical shock if your body is grounded.
3. Do not expose the impact wrench to rain, snow, frost or any other damp or wet conditions. Water entering a tool will increase the risk of electric shock.

BATTERY SAFETY

WARNING:  Only charge a battery with a charger designed for that purpose. Do not use modified chargers or a charger that does not specify the voltage, amperage or recharge rate. Improper charging can lead to battery rupturing.

WARNING:  Do not charge a damaged or frozen battery. Contact your local municipality for proper disposal procedures.

Consult the Safety Data Sheet (SDS) for your battery before use or maintenance.

1. Do not expose the battery to heat or throw it in a fire. The contents are flammable and the battery may explode. Remove any source of ignition such as an open flame or a tool like a heater from the area.
2. Do not inhale smoke issuing from a burning battery, as it is toxic.
3. Do not disassemble or crush the battery as the contents are corrosive and flammable. Exposure may cause an injury. There is a risk of escaping hazardous vapors. These vapors can irritate the respiratory track. Always ensure proper ventilation and immediately consult a doctor, if you feel unwell.
4. Even a discharged battery may still carry a charge. To prevent a shock, place battery terminal caps or covers over the terminal to prevent accidental contact. Hold the battery by the bottom if moving the battery to a different location.
5. A battery-operated tool with internal batteries or with a separate battery pack must only be powered by the battery. Do not mix different brands of tools and batteries or use adapters to allow you to use a battery pack with a different voltage. This can damage the tool’s electrical mechanism and create a fire hazard.
6. Leaking battery fluid can cause irritation of the skin or burns. If contact should occur, flush immediately with water. In case of accidental contact with the eyes, seek medical aid.
7. Do not disconnect from the power source in place of using the ON/OFF switch on the tool. This can lead to an accidental startup when the tool is connected to the power supply.
8. Do not allow a rechargeable battery to fully discharge. This will damage the battery. Recharge the battery as soon as possible.
9. Do not store the battery completely discharged. Charge it fully before storing. Recharge occasionally if storing for a long time.

CHARGER PRECAUTIONS

WARNING:  Voltage is present at the charging terminals, do not probe with conductive objects. Electric shock or electrocution may result. A battery short can cause a large current flow, overheating, possible burns and even a breakdown of the tool.

1. Only use the included battery charger to recharge the battery. Other chargers may be unsafe, causing an electrical short circuit or fire.
2. Disconnect the charger from its power source before attaching or removing batteries or battery clamps.
3. Charge the battery in a well-ventilated area and never obstruct the vents in the top and bottom of the charger. Place the charger on a flat nonflammable surface and away from flammable materials when re-charging the battery.
4. Do not place any object on top of the charger or place the charger on a soft surface that may result in excessive internal heat. Place the charger in a position away from any heat source.
5. Charge the battery at rates recommended by the battery manufacturer.
6. Make sure the polarity symbols on the battery lines up with the polarity symbols of the charger. A battery inserted backwards may explode causing fire and/or injury.
7. Do not use the charger with an extension cord. This can cause a low voltage outage during charging.
8. Do not charge leaking batteries. A compromised casing will release volatile chemicals and gases. Charging a leaking battery can cause a fire or explosion.
9. Do not operate the charger if it has received a sharp blow, been dropped or otherwise damaged in any way. Have it serviced or replaced.
