GENERAL SAFETY INSTRUCTIONS

WARNING: Before using this tool or any of its accessories, read this manual

and follow all Safety Rules and Operating Instructions. The important precautions,

safeguards and instructions appearing in this manual are not meant to cover all

possible situations. It must be understood that common sense and caution are

factors which cannot be built into the product.

EYE, EAR & LUNG PROTECTION

SYMBOL MEANING

ALWAYS WEAR EYE PROTECTION THAT CONFORMS WITH CSA Z94.3 or

ANSI SAFETY STANDARD Z87.1

FLYING DEBRIS can cause permanent eye damage.

Prescription eyeglasses ARE NOT a replacement for proper eye protection.

The usage of a safety standard compliant face shield placed over proper

safety glasses or goggles can reduce the risk of facial injury.

Non-compliant eyewear can cause serious injury if broken during the

operation of a power tool.

Use hearing protection, particularly during extended periods of operation

of the tool, or if the operation is noisy.

WEAR A DUST MASK THAT IS DESIGNED TO BE

USED WHEN OPERATING A POWER TOOL IN A

DUSTY ENVIRONMENT.

Dust that is created by power sanding, sawing, grinding, drilling, and other

construction activities may contain chemicals that are known to cause

cancer, birth defects,

or other genetic abnormalities. These chemicals include:

• Lead from lead-based paints

• Crystalline silica from bricks, cement, and other

masonry products

• Arsenic and chromium from chemically treated lumber

The level of risk from exposure to these chemicals varies, according to how

often this type of work is performed. In order to reduce exposure to these

chemicals, work in a

well-ventilated area, and use approved safety equipment, such as a dust mask

that is speciﬁcally designed to ﬁlter

out microscopic particles.

TO AVOID ELECTRICAL HAZARDS,

FIRE HAZARDS OR DAMAGE TO THE TOOL,

USE PROPER CIRCUIT PROTECTION.

This tool is wired at the factory for 120 V AC operation. It must beconnected

to a 120 V AC, 15 A circuit that is protected by a time-delayedfuse or circuit

breaker. To avoid shock or ﬁre, replace power cordimmediately if it is worn, cut

or damaged in any way.

WARNING: Ventilation openings in batteries and chargers must always

be open to allow cooling air to circulate freely. Air vents that are blocked,

restricted or covered may result in the battery or charger overheating.

Overheating may lead to damage to the tool or cause a ﬁre, resulting in

possible serious injury.

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

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

Double insulated tools are equipped with a polarized plug (one blade is wider

than the other). This plug will only ﬁt into a polarized plug one way.

If the plug does not ﬁt into the outlet properly, reverse the plug. If it still does

not ﬁt, contact a qualiﬁed electrician to install a polarized outlet. Do not alter

the plug in any way. Double insulation eliminates the need for the three-pronged

grounded power cord and grounded power supply system.

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. Do not use the power cord to carry the tool or to pull the

plug out of the outlet. Keep the power cord away from heat, oil, sharp edges,

and moving parts. Replace a damaged power cord immediately. A damaged power

cord increases the risk of electric shock.

When operating a power tool outdoors, use an outdoor-rated extension cord

type “W-A” or “W”. These cords are rated for outdoor use and they reduce 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

1239-301

20V MAX BRUSHLESS 1/2" IMPACT WRENCH

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.

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 jewellery. Keep your hair, clothing

and gloves away from moving parts. Loose clothes, jewellery 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.

Avoid accidental start-ups. Verify that the switch is in the OFF position before

plugging in the tool. Carrying a power tool with a ﬁnger on the switch or plugging in

a tool that has the switch in the ON position invites accidents.

Remove adjusting keys and wrenches before turning the tool ON. A wrench or key

that is left attached to a rotating part of the tool may result in personal injury.

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

and balance allows the operator to maintain better control of the tool in unexpected

situations.

Use safety equipment. Always wear eye protection.

Use a dust mask, non-skid safety shoes, a hardhat, or hearing protection when

appropriate.

POWER TOOL USE AND CARE

Use clamps or another practical means to secure and support the workpiece

to a stable platform. Holding the work in a hand or against the body is not stable

and may lead to loss of control.

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.

Any power

tool that cannot be controlled with the switch is dangerous and must be repaired.

Disconnect the plug from the outlet before making any adjustments, changing

accessories, or storing the tool. Such preventive safety measures reduce the risk

of accidental start-ups.

When power tools are not in use, store them out of the reach of children or

untrained persons. Tools are dangerous in the hands of untrained users.

Maintain power tools with care. Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges are less likely to bind, and are

easier to control.

Inspect the tool for misalignment or binding of moving parts, broken parts,

If it is

damaged, have the tool serviced before using it. Many accidents are caused by

poorly maintained tools.

Use only accessories that are recommended by the manufacturer for this

model. Accessories that are suitable for one tool may become hazardous when

used with another tool.

Tools servicing must be performed by qualiﬁed personnel. Service or

maintenance performed by non-qualiﬁed personnel could result in a risk of injury.

When servicing a tool, use only identical replacement parts. Follow the instructions

in the Maintenance section of this Manual. The use of unauthorized parts or failure

to follow the instructions in the Maintenance section of this Manual may create a

risk of electric shock or injury.

WARNING: Know your 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.

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: Glasses or goggles not in compliance with ANSI Z87.1 could

cause serious injury when they break.

WARNING: Always use a safety shield, hearing protection and dust mask

when drilling concrete.

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.

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

of the impact wrench.

Never use the impact wrench as a torque wrench. Always use a torque wrench to

adjust the fastener to the speciﬁed torque.
