AIR MOTOR GENERAL INFORMATION
The air motor is designed to be driven by
compressed air and under NO circumstances to
be driven by any other gases. The air motor must
not be driven by fluids, particles, solids or any
substance mixed with air, particularly combustible
or flammable substances likely to cause explosions.
Do not run mixer air motor with flammable or
explosive gases or operate the unit in an
atmosphere containing them.
The air motor is designed for compressed air
only. Do not allow corrosive gases or particulate
material to enter the motor. Water vapor, oil-based
contaminates, or other liquids must be filtered out.
EYE PROTECTION IS REQUIRED. Keep face away
from exhaust port.
