Installation Operation
IMPORTANT: A moisture separator/fil-
ter should be used to prevent contamina-
tion and the washout of lubricant.
The motor is packed with Teflon lubricant and
requires no additional lubrication except during service.
Lubricator
Alemite, LLC
recommends to operate the motor
without an air line lubricator.
CAUTION
Should an air line lubricator be installed, never
allow the motor to operate without lubrication
(minimum 10W oil) or the warranty will be void.
Motor Operation
WARNING
Read the label on the motor prior to
operation. Personal injury can occur.
Pneumatically actuated pilot valves (one set at each
end of a directional spool) cause the directional spool to
shift. The directional spool directs air pressure to one
side of the motor’s piston and allows air to exhaust
from the opposite side.
