To reduce the risk of injury, anyone using, repairing, maintaining, or

WARNING

changing accessories on this tool must read and understand these
instructions before performing any of these tasks.

Always inspect, operate, 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.

These tools are rated at 90 psig / 6.2 bar max air
pressure for safety, top performance, and maximum
durability of parts; do not exceed this pressure while
the tool is running.

Always shut off air supply, drain hose of air pressure
and disconnect tool from air supply when not in use,
before changing accessories, or when making repairs.

Never direct air at yourself or anyone else.
Always wear impact-resistant eye and face protection

when operating or performing maintenance on this tool.
High sound levels can cause permanent hearing loss.

Always use hearing protection when using this tool as
recommended by your employer or OSHA regulation.

Do not wear jewelry or loose fitting clothes.
Do not use quick disconnect couplings at tool. See

operating instructions for proper set up.
Whipping hoses can cause serious injury. Always

carefully check for damaged or loose hoses and fittings
before operating this tool.

Avoid direct contact with accessories during and after
use. Gloves should be worn to reduce the risk of cuts
or burns.

Use only sockets and accessories rated for use with
Impact Wrenches which are in good condition. Sockets
in poor condition or hand sockets and accessories can
shatter and cause injury.

Never run the tool off of the work. The tool may run
too fast and cause the accessory to be thrown off of
the tool.

Serious injury can result from over-torqued or
under-torqued fasteners. Assemblies requiring a
specific torque must be checked using a torque meter.

"Click" torque wrenches do not check for potentially
dangerous over-torque conditions.

Slipping, tripping, and/or falling while operating air tools
can be a major cause of serious injury or death. Be
aware of your surroundings and any excess hose left on
the walking or working surface.

Pneumatic tools can cause vibration 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. Consult a physician before
resuming use if any of these symptoms occur.

Do not stretch or overreach while using this tool.

If tool appears to malfunction, remove from service
immediately and arrange for repair.

Never use tool if there is any chance of coming into
contact with line electricity.

Use only Sunex certified spare parts for any repair made
to tool. Repairs should only be performed by properly
trained persons.

Do not lock, tape or wire the tool valve in the "on/off"
position.

Do not allow the exhaust air to come in contact with hot
surfaces or flames.

Avoid inhaling dust or handling debris from the work
process, which can be harmful to your health. Use dust
extraction and wear respiratory protective equipment
when working with materials which produce airborne
particles.

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 bricks and cement and 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 filter
out microscopic particles.

Additional Safety Warnings

Do not modify this tool or its accessories.
This tool is not recommended for use in explosive

atmospheres or underwater use.
Operators and maintenance personnel must be

physically able to handle the bulk, weight, and power
of this tool.

This tool is for professional use only.

Instruction Manual

This product is designed to tighten or loosen threaded
fasteners. No other use is permitted.

Air Supply Requirements

Tool is designed to operate at 90 psi (6.2 bar) at free speed
measured at the tool, of clean, dry air. Operating this tool at
higher pressures will drastically reduce the tool life and could
cause injury.

The air inlet thread on this tool is a standard 1/4" NPT.
Line pressure should be increased for any unusually long
air hose run (over 25 feet). Minimum hose diameter should
be 3/8" I.D. and all fittings should have the same inside
diameter. See diagram below for proper air supply setup.

Operation

This tool is a ratcheting tool and not a torque meter.
When specific torque is required, it must be checked with
a torque meter after fitting the fastener with the Ratchet.

If a nut does not move within five seconds, use a larger size
Ratchet. Do not use Ratchet Wrench beyond rated capacity,
as this can drastically reduce the tool life.
