The amount of actual torque may vary depending on the cleanness and condition of the threads and other
factors. If tightening critical components, check the actual torque applied to the fastener with a mechanical
torque wrench (not supplied).

that may occur. It must be understood by the operator that common sense and caution are factors which
cannot be built into this product, but must be supplied by the operator.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities,
contains chemicals known to the State of California to cause cancer and birth defects or other reproductive
harm. Some examples of these chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks and cement or other masonry products
• Arsenic and chromium from chemically treated lumber
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals:
work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are
specially designed to lter out microscopic particles. (California Health & Safety Code § 25249.5, et seq.)
Only use with accessories rated to handle the forces exerted by this tool during operation. Other accessories
not designed for the forces generated may break and forcefully launch pieces.
Attach all accessories properly to the tool before connecting the air supply. A loose accessory may detach or
break during operation.
Use this tool with both hands only. Using tools with only one hand can result in loss of control.
Do not lay the tool down until it has come to a complete stop. Moving parts can grab the surface and pull the
tool out of your control.
Anyone using vibrating tools regularly or for an extended period should rst be examined by a doctor and
then have regular medical check-ups to ensure medical problems are not being caused or worsened from
use. Pregnant women or people who have impaired blood circulation to the hand, past hand injuries, nervous
system disorders, diabetes, or Raynaud’s Disease should not use this tool. If you feel any symptoms related
to vibration (such as tingling, numbness, and white or blue ngers), seek medical advice as soon as possible.
• Do not smoke during use. Nicotine reduces the blood supply to the hands and ngers, increasing the risk of
vibration-related injury.
• Wear suitable gloves to reduce the vibration eects on the user.
• Use tools with the lowest vibration when there is a choice.
• Include vibration-free periods each day of work.
• Grip tool as lightly as possible (while still keeping safe control of it). Let the tool do the work.
• To reduce vibration, maintain tool as explained in this manual. If abnormal vibration occurs, stop immediately.

This Air Impact Wrench is made of wear-resistant and shockproof materials under strict quality control. Before
each use, make sure to lubricate the tool with 3 - 5 drops of engine oil through the air inlet. Do not add oil with
high viscosity. Re-connect air. Run impact wrench at low throttle without load for a few seconds to distribute the
oil throughout tool.
Keep the Air Cylinder and Gas Container clean and dry and make sure there is no leakage in the Air Supply
Tube.
Drain water from air compressor tank daily, as well as any condensation from air lines. Water in the air line may
enter the tool and cause damage.
Rule of Thumb
If it takes more than 8 seconds to tighten or loosen a bolt or nut with an air impact wrench at maximum setting,
the air wrench is too small or the air compressor CFM is not powerful enough for the job. Continued use in either
capacity will cause damage to the tool.
