Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to cause cancer, birth defects or
other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• 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.

also the responsibility of the tool owner to keep this
manual intact and in a convenient location for all to
see and read. If the manual or product labels are lost
or not legible, contact Matco Tools for replacements.
If the operator is not fluent in English, the product
and safety instructions shall be read and discussed
with the operator in the operator's native language by
the purchaser/owner or his designee, making sure that
the operator comprehends its contents.
• 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.
• Keep body working stance balanced and firm. Do
not overreach when operating the tool.
• Place the tool on the work before starting the tool. Do not
point or indulge in any horseplay with this 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.
• 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 or accessories. Do not use
hand sockets or accessories.
• Use only impact sockets and accessories that are
recommended by the manufacturer for your model.
Accessories that may be suitable for one tool may
create a risk of injury when used on another tool.
• Use accessories recommended by Matco Tools.
• Do not lu bri cate tools with flam ma ble or vol a tile liq uids
such as ker o sene, die sel 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.

MT2260 3 Rev. 08/16/19
POWER MANAGEMENT SYSTEM AND TOOL OPERATION
This tool includes a power management system that allows the
operator to adjust the amount of output power in the clockwise
direction (forward). There is no power management system
present in the counter-clockwise direction (reverse). To adjust
the power output in the forward direction, turn the dial shown
below left or right in the desired power direction. Power output
is indicated by enlarging black swoosh on back housing. Lowest
power setting indicated by thin swoosh area with highest power
setting being thickest swoosh area.
The Power management system is only for reference and do
not act as specific power settings. This tool includes a tip valve
variable speed trigger design that further allows the operator to
reduce the power output.
This tool is an impacting 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 Impact.
If a fastener does not move within five seconds, use a larger size
Impact. Do not use Impact Wrench beyond rated capacity, as this
can drastically reduce the tool life.
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.
NOTE: Actual torque on a fastener is directly related to joint
hardness, tool speed, condition of socket and the time the tool is
allowed to impact.
Use the simplest possible tool-to-socket hook up. Every
connection absorbs energy and reduces power.
NOTE: During operation, safety goggles must always be worn to
guard against flying rust and chips (users and bystanders).

AIR INLET
TRIGGER
AIR SUPPLY
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 below figure.
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.
Ensure an accessible emergency shut off valve has been installed
in the air supply line and make others aware of its location.
TROUBLESHOOTING
Other factors outside the tool may cause loss of power or erratic
action. Reduced compressor output, excessive drain on the air line,
moisture or restrictions in air pipes or the use of hose connections
of improper size or poor conditions may reduce air supply. Grit or
gum deposits in the tool may cut power and may be corrected by
cleaning the air strainer and flushing out the tool with gum solvent oil
or an equal mixture of SAE #10 and kerosene. If outside conditions
are in order, disconnect tool from hose and take tool to your nearest
authorized service center.
LUBRICATION & MAINTENANCE
Lubricate the air motor daily with high quality air tool oil. If no air
line oiler is used, run 1/2 oz. of oil through the tool. The oil can
be squirted into the tool air inlet or into the hose at the nearest
connection to the air supply, then run the tool. A rust inhibitive
oil is acceptable for air tools.
After an air tool has been lubricated, oil will discharge through
the exhaust port during the first few seconds of operation. The
exhaust port must be covered with a towel before applying air
pressure to prevent serious injury.
