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.

MT1735 3/8" Composite Impact Wrench
This Instruction Manual Contains Important
Safety Information.
Read THIS INSTRUCTION MANUAL Carefully
and understand ALL INFORMATION Before
Operating THIS Tool.
• 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 and face
protection when operating or performing
maintenance on this tool. Always wear hearing
protection when using this tool.
• High sound levels can cause permanent
hearing loss. Use hearing protection as
recommended by your employer or
OSHA regulation.
• 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.
• 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.
• Place the tool on the work before starting the
tool. Do not point or indulge in any horseplay
with this tool.
• 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.
• 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.
• Never use a chisel as a handstruck tool. They
are designed and heat treated to be used only
in air hammers. Select the correct shank and
retainer for the tool.
• Never use dull accessories. Never cool a hot
accessory in water as brittleness and early
failure can result. Accessory breakage or tool
damage may result from prying. Take smaller
bites to avoid getting stuck.
• Do not lubricate tools with flammable or
volatile liquids such as kerosene, diesel or
jet fuel.
• Do not force tool beyond its rated capacity.
• Do not remove any labels. Replace any
damaged labels.
• Use accessories recommended by Matco Tools.
FAILURE TO OBSERVE THESE WARNINGS COULD RESULT IN INJURY
OPERATION
The reversing valve can be used as an air throttle, if there are no
other means of regulating air. Turn the reversing valve all the way
to the right for maximum power.
The reversing valve can be used to adjust torque to the
approximate tightness of a known fastener.
To set the tool to desired torque, select a nut or screw of known
tightness of the same size, thread pitch and thread condition
as those on the job. Turn reversing valve to low position, apply
wrench to nut and gradually increase power (turn regulator to
admit more air) until nut moves slightly in the direction it was
originally set. The tool is now set to duplicate that tightness
- note regulator setting for future use. When tightening nuts not
requiring critical torque values, run nut up flush and then tighten
an additional one-quarter to one-half turn (slight additional
turning is necessary if gaskets are being clamped). For additional
power needed on disassembly work, turn regulator to its fully
open position. This impact wrench is rated at 1/2" USS bolt
size. Rating must be down graded for spring U bolts, tie bolts,
long cap screws, double depth nuts, badly rusted conditions and
spring fasteners as they absorb much of the impact power. When
possible, clamp or wedge the bolt to prevent springback.
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.

AIR SUPPLY
Tools of this class operate on a wide range of air pressures. It is
recommended that air pressure of these tools measures 90 PSI
at the tool while running free. Higher pressure and unclean air
will shorten tool life because of faster wear and may create a
hazardous condition.
Water in the air line will cause damage to the tool. Drain the air
tank daily. Clean the air inlet filter screen on at least a weekly
schedule. The recommended hook-up procedure can be viewed
in Figure 1.
The air inlet (Figure 2), used for connecting air supply, has standard
1/4" NPT American Thread.
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.
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. If
outside conditions are in order and the tool still has erratic
performance, disconnect tool from hose and take tool to your
nearest Matco authorized service center.
LUBRICATION & MAINTENANCE
Lubricate the tool daily with a good grade of air tool oil. If no
air line oiler is used, run a teaspoon of oil through the tool. The oil
can be squirted into the tool air inlet Figure 2, 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.
