POWER TOOL SAFETY
WARNING:Read all safety warnings and instructions. Failure to follow the
warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. 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.
3. Keep children and bystanders 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 earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
2. 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.
3. DO NOT expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
4. 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.
5. 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.
6. If operating a power tool in a damp location is unavoidable, use a residual
current device (RCD) protected supply. Use of a ground fault circuit
interrupter (GFCI) 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 serious personal injury.
2. 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.
3. 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.
4. 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.
5. DO NOT overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.
6. 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.
7. 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.
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.
2. 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.
3. 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.
4. 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.
5. Maintain power tools. 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.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
7. 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.
BATTERY TOOL USE AND CARE
1. 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.
2. Use power tools only with specifically designated battery packs. Use of any
other battery packs may create a risk of injury and fire.
3. 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.
4. Under abusive conditions, liquid may be ejected from the battery; avoid contact.
If contact accidentally occurs, flush with water. If liquid contacts eyes, seek
medical help. Liquid ejected from the battery may cause irritation or burns.
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.
WARNING:
1. Know your cordless Impact Wrench. DO NOT plug in the charger or install the
battery in the tool until you have read and understand this Instruction Manual.
Learn the tool’s applications and limitations, as well as the specific potential
hazards related to this tool. Following this rule will reduce the risk of electric
shock, fire, or serious injury.
2. Always wear eye protection. Any power tool can throw foreign objects into
your eyes and cause permanent eye damage. ALWAYS wear safety goggles
(not glasses) that comply with ANSI safety standard Z87.1. Everyday glasses
have only impact resistant lenses. They ARE NOT safety glasses.
WARNING:
3. Glasses or goggles not in compliance with ANSI Z87.1 could cause serious
injury when they break.
4. Always use hearing protection when operating the Impact Wench.
5. Use only Impact sockets and accessories that are designed for use with
an Impact Wrench. DO NOT use chrome plated sockets and accessories.
Chrome plated sockets and accessories are designed for hand use only and
MUST NOT be used with an Impact Wrench. They may shatter and possibly
cause serious injury.
6. Before each use, check the Impact sockets and accessories for excessive
wear or cracks. Worn or damaged sockets or accessories may shatter and
possibly cause serious injury. Worn accessories may allow the socket to
come off during operation of the Impact Wrench.
7. After installing any accessory in the hex drive, pull outward on the accessory
to ensure it is properly installed and cannot be pulled out of the hex drive.
8. Never use the Impact Wrench as a torque wrench. Always use a torque
wrench to adjust the fastener to the specified torque.
9. Keep the Impact Wrench handle and body clean and free of oil and grease.
Always use a clean dry cloth when cleaning. DO NOT use solvents, brake fluid,
gasoline or other petroleum products to clean the tool. They will damage the tool.
10. DO NOT wear neckties or loose clothing.
11. When wearing gloves, they must be tight fitting and slip resistant type.
Leather gloves offer the best protection.
