• Read, Study, understand & follow all instructions before operating this product.
• Always operate, inspect and maintain this tool in accordance with American National Standards Institute Safety Code of
Portable Air Tools (ANSI B186.1) and any other applicable safety codes and regulations.
• For safety, top performance and maximum durability of parts, operate this tool at 90 psig; 6.2 bar max air pressure with
3/8" diameter air supply hose.
• Always wear impact-resistant eye protection when operating or performing maintenance on this tool (users and bystanders).
• High sound levels can cause permanent hearing loss. Always use hearing protection as recommended by your employer an
OSHA regulations while using this tool (users and bystanders).
• Keep the tool in efficient operating condition.
• Operators and maintenance personnel must be physically able to handle the bulk, weight and power of this tool.
• Air under pressure can cause severe injury. Never direct air at yourself or others. Always turn off the air supply, drain hose
of air pressure and detach tool from air supply before installing, removing or adjusting any accessory on this tool, or before
performing any maintenance on this tool. Failure to do so could result in injury. Whip hoses can cause serious injury. Always
check for damaged, frayed or loose hoses and fittings, and replace immediately. Do not use quick detach couplings at tool.
See instructions for correct set-up.
• Keep tool out of reach of children.
• Air powered tools can vibrate in use. Vibration, repetitive motions or uncomfortable positions over extended periods of time
may be harmful to your hands and arms. Discontinue use of tool if discomfort, tingling feeling or pain occurs. Seek medical
advice before resuming use.
• Slipping, tripping and/or falling while operating air tools can be a major cause of serious injury or death. Be aware of excess
hose left on the walking or work surface.
• Place the tool on the work before starting the tool. Do not point or indulge in any horseplay with this tool.
• Keep body working stance balanced and firm. Do not overreach when operating the tool.
• Note direction of rotation BEFORE operating this tool.
• Anticipate and be alert for sudden changes in motion during start up and operation of any power tool.
• Do not carry tool by the hose. Protect the hose from sharp objects and heat.
• Tool shaft may continue to rotate briefly after throttle is released. Avoid direct contact with accessories during and after use.
Gloves will reduce the risk of cuts or burns.
WARNING: Indicates a hazardous situation
which, if not avoided, could result in death
or serious injury.

WARNING INFORMATION
CONSEQUENCES OF NOT AVOIDING HAZARDOUS SITUATIONS
Failure to read this manual completely and thoroughly, failure to understand its OPERATING INSTRUCTIONS, SAFETY
WARNINGS, MAINTENANCE INSTRUCTIONS and comply with them, and failure to comply with the METHODS TO AVOID
HAZARDOUS SITUATIONS could cause accidents resulting in serious or fatal personal injury and/or property damage.
• Keep away from rotating end of tool. Do not wear jewelry or loose clothing. Secure long hair. Scalping can occur if hair
is not kept away from tool and accessories. Choking can occur if neckwear is not kept away from tool and accessories.
• Do not use (or modify) the tool for any other purpose than that for which it was designed without consulting the
manufacturer's authorized representative.
• Impact wrenches are not torque control devices. Fasteners with specific torque requirements must be checked with
suitable torque measuring devices after installation with an impact wrench.
• Use only impact sockets and accessories on this tool. Do not use hand sockets and accessories.
• Use accessories recommended by Arcan.
• Do not lubricate tools with flammable or volatile liquids such as kerosene, diesel or jet fuel.
• This tool is not insulated against electric shock.
• This tool must not be used in explosive atmospheres.
• Servicing and repairs should only be made by an authorized service center.
• Do not force tool beyond its rated capacity.
• Do not remove any labels. Replace damaged labels.
• Failure to heed these warnings may result in serious or fatal personal injury and/or property damage.
WARNING: This product can expose you to chemicals including nickel, which is known to the State of California to
cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
WARNING
INSTRUCTION MANUAL
This product is designed to tighten or loosen threaded fasteners. No other use is permitted.
AIR SUPPLY REQUIREMENTS
Tools operate on a wide range of air pressures. It is recommended that air pressure measures 90 psig at the tool with the trigger fully
depressed and no load applied to the tool. Higher pressure (over 90 psig; 6.2 bar) raises performance beyond the rated capacity of the
tool, which will shorten tool life and could cause injury.
Always use clean, dry air. Dust, corrosive fumes and/or water in the air line will cause damage to the tool. Drain the water from air lines
and compressor prior to running tool. Clean the air inlet filter screen weekly. The recommended hookup procedure can be viewed in
the Figure 1.
The air inlet used for connecting air supply has standard 1/4" NPT. Line pressure should be increased to compensate for unusually
long air hoses (over 25 feet). Minimum hose diameter should be 3/8" I.D. and fittings should have the same inside dimensions and be
tightly secured.
Always turn off the air supply, drain hose of air pressure and detach tool from air supply before installing, removing or adjusting any
part or accessory on this tool, or before performing any maintenance on this tool.
Ensure an accessible emergency shut off valve has been installed in the air supply line and make others aware of its location.

OWNER'S MANUAL
LUBRICATION
Lubricate the air motor daily with high quality air tool oil. If air tool oil is not available, use SAE #10 weight oil as an alternative. The
preferred method for air motor lubrication is an inline oiler as shown in FIGURE 1. If this configuration is not utilized, then oil the tool
manually by disconnecting the tool from air compressor and injecting 10 drops of air tool oil directly into the air inlet before use. Fol-
low by reconnecting the air supply and run the tool for 3 seconds. Be careful of excess oil being expelled from the exhaust. Cover the
exhaust with a shop rag. Make sure to point the tool exhaust away from you. Repeat this process of injecting 10 drops of oil after the
final use and before storing the tool. This will protect the tool from rusting during long term storage.
WARNING: After an air tool has been lubricated, oil will discharge through the exhaust port during the first few seconds of opera-
tion. The exhaust port must be covered with a towel before applying air pressure to prevent serious injury.
GREASING THE HAMMER MECHANISM
This tool is equipped with a grease fitting for maintaining the impact mechanism. Overfilling with grease will cause a reduction in
performance. Using a mini grease tool inject 1-3 pumps of air tool grease every 3-6 months
OPERATION
Always turn off the air supply, drain hose of air pressure and detach tool from air supply before installing, removing or adjusting
any part or accessory on this tool, or before performing any maintenance on this tool.
Soak rusted nuts in penetrating oil and break rust seal before removing with impact wrench. If nut does not start to move in three to
five seconds, use a larger size impact wrench. Do not use impact wrench beyond rated capacity as this will drastically reduce tool life.
NOTE: Actual torque on a fastener is directly related to joint hardness, tool speed, condition of socket and the time the tool is al-
lowed to impact. Use the simplest possible tool-to-socket hook up. Every connection absorbs energy and reduces power.
WARNING: Use only impact sockets and accessories on this tool. Do not use hand sockets and accessories.
