Your safety and the safety of others

is extremely important.

We have provided many important safety messages
in this manual and on your product.  Always read
and obey all safety messages.

This is the safety alert symbol.  This symbol

alerts you to hazards that can kill or hurt you and
others.  The safety alert symbol and the words
“DANGER” and “WARNING” will precede all safety
messages.  These words mean:

You will be killed or seriously injured if you don’t
follow instructions.

You can be killed or seriously injured if you don’t
follow instructions.

All safety messages will identify the hazard, tell you
how to reduce the chance of injury, and tell you
what can happen if the safety instructions are not
followed.  

Correct installation is your responsibility. Make
sure you have the proper installation conditions and that
the specified installation clearances are available.

INSTALLATION

Accessories
A muffler is shipped with the air motor (except 16AM)
but is not installed.  Consult your Gast representative  

WARNING

DANGER

Connection
Check the direction of the motor airflow.  A single
rotation motor will operate properly only in one direction.
Install a filter in the air line before the connection to the
motor.  Connect lines to motor in the proper direction.
A reversible motor will work equally well in both
directions.  Connecting a 4-way valve with piping to
both air ports of the motor will make reversing possible.

Do not add any thrust to the end or side of the shaft
when making connections.  Do not use a hammer
on the shaft or connections.

Mounting
This product can be installed in any orientation.  Mount
the motor to a solid base plate that is mounted to a
stable, rigid operating surface.  Install a pressure
regulator or simple shut-off valve to control motor.

Injury Hazard

Install proper guards as needed.

Failure to follow this instruction can result in
burns or other serious injury.

WARNING

for additional filter recommendations.  Install a moisture
trap and filter in the air line ahead of the motor.  For the
most efficient output and control of speed, use air lines
that are the same size or the next pipe size larger than
the motor intake port.

An automatic air line lubricator should be installed 18”
or as close as possible in the air line just ahead of the
motor.  Adjust the lubricator to feed one drop of oil for
every 50-75 CFM of air moving through the motor.  Air
consumption at various speeds and pressures are
available from your local Gast representative or the
factory.   

It is your responsibility to operate this product at
recommended speeds, loads and room ambient
temperatures.  Do not run the motor at high speeds
with no load. This will result in excessive internal
heat that may cause motor damage.

The starting torque is less than the running torque.  The
starting torque will vary depending upon the position of
the vanes when stopped in relation to the air intake
port.

Use a pressure regulator and/or simple shut-off valve to
regulate the motor’s speed and torque.  This will provide
the required power and will conserve air.
