Safety Instructions
Warning: If not followed could
cause personal injuries
Caution: If not followed could result in dam-
age to equipment.
Warning
is manual must be read and the operating
instructions carefully followed.
Warning
Safety and protective clothing, eyewear,
headgear, ear protection, gloves and foot-
wear to be worn during operation of this
piston motor
Caution
Install proper guard around the output sha
as needed.
Warning.
Operators under 18 not allowed to operate
this Piston motor operators must be made
familiar with the instructions in this man-
ual before attempting to operate the piston
motor Ensure that job site is clear of by-
standers. Do Not dis-assemble in explosive
atmosphere.
Caution
Use only genuine Teryair or Teryair ap-
proved accessories.
Intended And Prohibitive Use
Intended Use
Prohibitive use
Use with non-genuine spare parts or
accessories is prohibited
Caution
Completely turn o the piston motor and
disconnect air supply line before attempting
any service. Read Assembly and Dis-assembly
instructions.
Warning
Do not use a hammer on the sha or
connections. Do Not dis-assemble in explosive
atmosphere.
Warning
Take care not to exceed the supply air pressure
maximum 7kg/cm²(100 psi) for Lubricated and
maximum 5.6 kg/cm²(80 psi) for Lube-free .
Caution
Do not exert excessive pressure against the
work surface. Keep hoses in good condition.
Check hoses for signs of wear, cracks & bulges
and ensure that they are secure. Accidental
disconnection while hose is pressurized makes
the hose whip and can be a safety hazard.
Caution
• Please check the hose connection prior to
starting motor
• Keep hands & clothing away from
moving parts.
• Store these piston motors in secure & dry
environment.
• Do not modify this piston motor in any
way as this will invalidate the warranty and
could lead to serious injury.
• Do not drag this piston motor by air hose.
Following symbols are used through out this
manual.

Warning
Check the site to make sure that the piston
motor will be adequately ventilated and that
there is no external heat input.
Installation Instructions
An automatic air line lubricator should be in-
stalled in the air line as close as possible and no
more than 18inches (1/2 meter) from the air
motor. Install the lubricator level with or above
the air motor so that the oil mist will blow direct-
ly into or fall down into the motor. Install a ilter
in the air line before the connection to the motor.
Next install an air pressure regulator to control
motor speed and torque.
Clean the compressed air connection with low
pressure air to remove any dirt from the line
before connecting to the ports. Use the proper
sized fasteners. For the most ecient output and
control of speed, use air lines that are the same
size as the motor inlet port if the connection is
less than 7 feet (2 meters). For longer connec-
tions, use the next pipe size larger than the motor
intake port. Connect lines to motor in the proper
direction
Safety wear mandatory while operating Piston
motor
Air stream from product may contain solid o
liquid particle that can result eye or skin dam
age.Eye and face and ear protection must be
worn at all times during operation
Suitable gloves must be worn at all times during
operation.
Daily Before Operating
1. Disconnect air line and muer.
2. Add ushing solvent directly into motor. If
using liquid solvent pour in 1 to 2 ounces of
recommended oil into the motor.
3. Rotate the sha by hand in both directions for
a few minutes.
4. You must wear eye protection for this step.
Cover exhaust with a cloth and reconnect the
air line.
5. DO NOT use kerosene or ANY other
combustible solvents to ush this product.
6. Restart the motor at a low pressure of
approximately 10 PSI/0.7 bar until there is no
trace of solvent in the exhaust air.
7. Listen for changes in the sound of the motor.
If motor sounds smooth, you are nished.
If motor does not sound like it running
smoothly, installing a service kit will be
required.
Air Supply
e air should be clean and dry. Supply
air pressure maximum 7kg/cm²(100 psi) for
Lubricated and maximum 5.6 kg/cm²(80 psi) for
Lube-free.
Hoses
• Daily before operation check the hoses,
especially the high pressure hoses for damage
or leaks
• Use genuine Teryair spares and if possible
mention the serial number of the piston
motor when ordering spares.
Operating instructions
Piston motors are rugged dependable product
designed to give you years of satisfactory
service. Follow the instructions mentioned here
to enhance life and performance. Check the
direction of the motor airow. A single rotation
motor will operate properly only in one
direction.Single rotation motors require a
muer to be connected to the air port. Remove
the plastic shipping plugs from the ports. Save
plugs for future use during shutdown.

Mounting
is product can be installed in any orientation.
Mount the motor to a solid metal base plate that is
mounted to a stable, rigid operating surface. Use
shock mounts to reduce noise and vibration. Install
a pressure regulator or simple shut-o valve to
control motor.
Storage
• It is your responsibility to follow proper
shutdown procedures before storage.
• Turn o air intake supply.
• Disconnect air supply and vent all air lines.
• Remove Piston motor from connecting
machinery.
• Remove the muer.
• Wear eye protection. Keep away from air stream.
Use clean, dry air to remove condensation from
the inlet port of the motor.
Troubleshooting
L ow Torque Low Speed Won’t run Runs well but
slows down Reason & Remedy for problem
√ √ √ Dirt or foreign material present. Inspect
and ush.
√ √ √ Internal rust. Inspect and ush.
√ √ Low air pressure. Increase pressure.
√ Air line too small. Install larger line(s).
√ √ Restricted exhaust. Inspect and repair.
√ √ √ √ Motor is jammed. Have motor serviced.
√ √ Air source inadequate. Inspect and repair.
√ √ Air source too far from motor. Recongure
setup.

• Lubricate motor with a small amount of
oil into the intake port. Rotate sha by
hand several times to distribute oil.
• Plug or cap each port.
• Coat output sha with oil or grease.
• Store motor in a dry environment.
Lubrication Requirements
Lubricated Piston motor: Always install a line
lubricator on the air line as close to the Piston
motor as possible. A Filter Regulator Lubri-
cator unit (FRL) is strongly recommended.
Keep the lubricator bowl topped up with
recommended grade of oil and check that the
oil is reaching the Piston motor Running the
Lubricated Piston motor without lubrication
is likely to cause damage to the components
causing premature replacement.
