Introduction
Thank you for purchasing this quality product. To minimise the risk of injury we urge that our clients
take some basic safety precautions when using this device. Please read the operation instruc-
tions carefully and make sure you have understood its content.
Keep these operation instructions safe.
Important safety instructions
WARNING! When you use tools, basic precautions should always be followed.
Risk of fire and injuries!
Work area safety
•Keep the work area tidy and well lit. Untidy benches and dark areas increase risk of electric
shock, fire and injury to persons.
•Do not operate tool in explosive atmospheres, such as in the presence of flammable liquids,
gases, or dust.
•Keep bystanders, children, and visitors away while operating the tool. Distractions may result in
personal injury and/or injury of others.
Personal safety
•Always wear eye protection. Operator and others within work area should always wear approved
safety goggles with side shields. Eye protection is used to guard against flying fasteners and
debris, which may cause severe eye injury.
•Always wear hearing protection when using the tool. Extended exposure to high intensity noise
may cause hearing loss.
•Use safety equipment. A dust mask, non-skid safety shoes and a hard hat must be used for the
applicable conditions.
•Do not wear loose fitting clothing or jewellery. Use a helmet for long hair. These items can get
caught in moving parts, causing serious personal injury.
•Stay alert, watch what you are doing and never operate the tool while being tired or under the
influence of drugs, alcohol, or medicine. A moment of inattention while operating the tool in-
creases the risk of injury to persons.
•Remove adjusting keys and wrenches before switching the tool on. A wrench or a key that is
left attached to a rotating part of the tool increases the risk of injury to persons.
•Always keep proper footing and balance. Do not use on a ladder or an unstable support. Proper
footing and balance enable better control of the tool in unexpected situations.
•Make sure the hose is free of obstructions or snags. Entangled or snarled hoses can cause loss
of balance or footing and may become damaged resulting in possible injury.
•Do not attach the hose or tool to your body. Attach the hose to the structure to reduce the risk
of loss of balance if the hose shifts.
•Avoid unintentional starting. Be sure the switch is off before connecting the air supply. Do not
carry the tool with your finger on the switch or connect the tool to the air supply when switched
on.
•Wash hands after handling.
Tool use and care
•Get to know this tool. Read the manual carefully, learn its application and limitations, as well as
the specific potential hazards related to this tool.

•Do not force the tool. Use the correct tool for the application. The correct tool will do the job
better and safer at the rate for which it has been designed for.
•WARNING! Disconnect the tool from the air source before making any adjustments, changing
accessories or before storing the tool. Such precautionary measures reduce the risk of injury to
persons.
•Check for misalignment or binding of moving parts, breakages and any other conditions that
may affect the tool in its operation and safety. Damaged tools must be repaired before using
them. Many accidents are caused by poorly maintained tools. There is a risk of bursting if the
tool is damaged.
•Store the tools in a secure place when not in use and keep them out of reach of children and
other untrained persons. A tool is dangerous in the handy of untrained users.
•Holding a work piece by hand or against the body is unstable and may lead to loss of control.
•Keep the tool and its handle dry, clean, and free from oil and grease. Always use a clean cloth
when cleaning it. Never use brake fluids, petrol, petroleum-based products, or any strong sol-
vents to clean your tool.
•Do not use the tool as hammer.
•Never use petrol or flammable liquids to clean the tool. Never use the tool in the presence of
flammable liquids or gases. Vapours can be ignited by a spark and cause an explosion that will
result in death or serious personal injury.
•Do not remove or manipulate the trigger. Never cause the trigger lock to become inoperable.
Do not operate any tool which has been modified in any way. Death or serious personal injury
can be the result.
•Never use the tool if the switch does not work. Any tool that cannot be controlled by the switch
is dangerous and must be repaired before using it again.
•Always fit the tool with a fitting or hose coupling on or near the tool that all compressed air is
discharged at the same time when the fitting or hose coupling is disconnected. Do not use a
check valve or any other fitting that allows the air to remain within the tool. Death or serious
personal injury might be the result.
•Never carry the tool by the air hose or pull the hose to move the tool away from a compressor.
Keep hoses away from heat, oil, and sharp edges. Replace any hose that is damaged, weak,
or worn. Otherwise, this might result in personal injury or damage to the tool.
•Do not drop or throw the tool. Dropping or throwing the tool can result in damage that will make
the tool unusable or unsafe. If the tool has been dropped or thrown, examine the tool closely for
bent, cracked or broken parts or any air leaks. If the tool has any damages, it must be repaired
before being used again to avoid taking serious injuries.
•Clean and check all air supply hoses and fittings before connecting the tool to an air supply.
Replace any damaged or worn hoses or fittings. This will reduce tool performance or its dura-
bility.
•Do not use the tool if it leaks air or does not function properly.
•Do not operate the tool if it does not contain a legible warning label.
Maintenance
•Use only accessories that are allowed by the manufacturer.
•When servicing a tool, only use original spare parts.
•Only use supplied lubricants specified by the manufacturer.
•Tool service must only be performed by the manufacturer or an authorized service partner.
Operation
•The amount of actual torque may vary depending on the cleanliness and condition of threads
and other factors.
•The warnings and precautions discussed in this manual cannot cover all possible conditions
and situations that may occur. Always be aware and cautious while working with the tool.
•Only use it with accessories that are rated to handle the forces exerted by this tool during oper-
ation. Other accessories which are not designed for the generated forces may break and force-
fully launch pieces.
•Attach all accessories properly to the tool before connecting the air supply. A loose accessory
may detach or break during operation.

•Obey the manual for the air compressor used with this power tool.
•Install an in-line shut-off valve to allow immediate control over the air supply in an emergency,
even if a hose is ruptured.
•Use this tool with both hands only. Using tools with only one hand can result in loss of control.
•Do not lay down the tool until it has come to a complete stop. Moving parts can grab the surface
and pull the tool out of your control.
•Always handle the tool with care:
◦Respect the tool as a working implement.
◦Never pull the trigger unless nose is directed toward the work.
◦Keep others in a safe distance from the tool while the tool is in operation as accidental
actuation may occur possibly causing injury.
Air supply and connections
•Do not use any type of reactive gases like oxygen carbon dioxide and combustible gases as a
power source. Use filtered, lubricated, regulated compressed air only. Use of a reactive gas
instead of compressed air may cause the tool to explode which will cause death or serious
personal injury.
•Use only a pressure-regulated compressed air source to limit the air pressure supplied to the
tool. The regulated pressure must not exceed 6 bar (90 psi). If the regulator fails, the pressure
must not exceed 6 bar (90 psi). The tool could explode which will cause death or serious per-
sonal injury.
•Always disconnect air source
◦before making adjustments,
◦when servicing the tool,
◦when the tool is not in use,
◦when moving the tool to a different work area as accidental actuation may occur causing
injury
•Never connect the tool to an air source that may exceed 6 bar (90 psi). Over-pressurising the
tool may result in bursting, abnormal operation, breakage of the tool as well as serious personal
injury. Use only clean, dry, regulated compressed air at the rated pressure or within the rated
pressure range as marked on the tool. Always verify prior to using the tool that the air source
has been adjusted to the rated air pressure or within the rated air-pressure range.

Operating procedures
Setting up the air source
•The ½″ air impact wrench is designed to operate on clean, dry, compressed air, regulated at
6bar (90 psi). The preferred system would include a filter, a pressure regulator and an auto-
matic oiler located as close to the tool as possible, ideally within 4.5 m (15 ft). Do not use bottled
air or gases.

the in-line oiler has sufficient oil. If an in-line oiler is not available,
place 2 drops of oil into the air inlet of the tool at the beginning of
each workday. More than this will be expelled from the exhaust of
the tool during using (Fig. 3).
•Air fitting: The ½″ air impact wrench should be equipped with a ¼″
NPD male quick connector (not included). To prevent accidental
cycling even though disconnected, the tool must always be con-
nected to the air supply in a way that all air pressure within the
tool is released when the coupling is disconnected.
CAUTION:
•All air pipe components (including hoses, pipe, connect-
ors, filters, regulators etc.) must be rated for a working
pressure of 6 bar (90 psi).
•Disconnect the tool from the air supply before performing maintenance, leaving the work
area, moving the tool to another location, or handing it to another person.
Preparing the tool
•Drain water from the air compressor tank and any condensation from air lines. (Please refer to
the operation manual of the air compressor.)
•Lubricate the tool. (Please refer to the maintenance section in this manual.)
•Select the necessary impact sockets. The sockets must match the size of the drive on the air
impact wrench.
•Connect air impact wrench to the air source using the recommended hose size.
CAUTION:
•Always keep the tool pointed away from yourself and any other person.
•Never use a tool that leaks air or needs repair.
Operating the tool
•Remove the plastic air inlet protective cap (fig. 4, 2) from
the air inlet (Fig. 4, 1) as shown.
•Prepare a ¼″ male plug (Fig. 5, 2) (not included) by ap-
plying sealant tape to the threading, wrapping clockwise.
Screw the threaded male air plug by hand into the air inlet
(Fig. 5, 1) as shown and tighten it with a wrench (not in-
cluded) for an airtight connection. Note: Do not over-
tighten! Sealant tape must be used on this connec-
tion.
•Push the control valve (Fig. 5, 3) forward so that the end
of the valve protrudes out above the trigger for a clock-
wise (“forward”) tool operation.
•Push the control valve back so that the end of the valve
protrudes from the back of the housing for counter-clock-
wise (“reverse”) tool operation.
•Adjust the air flow by pushing down the air regulator
(Fig. 6, 1) and turning the knob from positions “1” (lowest
amount of air flow) to “4” (highest amount of air flow),
aligning the desired number setting with the recessed ar-
row.
•Push and snap the required ½″ drive impact socket (not
included) onto the anvil.
CAUTION:
•Always keep the tool pointed in a safe direction.

•Only use impact rated accessories with this tool. Other accessories may shatter, chip or
crack during operation.
•Clean and inspect the tool daily. Carefully check for proper operation of trigger and safety
mechanism. Do not use the tool unless both the trigger and safety mechanism are func-
tional, if the tool is leaking air or needs any other repair.
Regular maintenance
•Clean and inspect the tool daily. Make sure the tool is disconnected from the air supply.
•Blow the tool clean with compressed air and inspect for wear and damage. Use non-flammable
cleaning solutions to wipe the exterior of the tool, only if necessary. DO NOT SOAK the tool
with cleaning solutions. Such solutions can damage internal parts.
•Inspect the trigger and the safety mechanism to ensure the system is complete and functional.
Check for loose or missing parts as well as parts that may be stuck.
•Keep all screws tight. Loose screws may cause personal injury.
•Place two or three drops of pneumatic oil (included) into the air inlet of the tool daily.
•BEFORE EACH USE inspect the general condition of the tool.
Check for:
◦loose hardware or housing,
◦misalignment or binding of moving parts
◦cracked or broken parts,
◦any other condition that may affect its safe condition
•Daily – air supply maintenance: Every day, maintain the air sup-
ply according to the component manufacturers’ instructions. Main-
tain the oil level of the lubricator. Drain the moisture filter regularly.
Performing routine air supply maintenance will allow the tool to
operate more safely and will also reduce wear on the tool.
•Weekly – lubrication: Add a high-quality machine oil to the oil
inlet (Fig. 7, 1) by removing the oil screw (Fig. 7, 2).
•Quarterly (every 3 months) – tool disassembly, cleaning, and
inspection: Have the internal mechanism cleaned, inspected,
and lubricated by a qualified technician.
