Important Safeguards
Read the entire Installation, Operation and Maintenance Manual before installing,
operating, or servicing this actuator.
Inspect the actuator regularly for signs of corrosion and repair immediately.
Always remove pressure and disconnect power supply before servicing the actuator.
Keep hands and feet clear of an actuator that is in service.
Do not disassemble the actuator without reviewing the disassembly procedure
in this manual first. This is particularly important that the proper procedure be
followed to avoid injury from internal spring power.
Before attempting to remove an actuator from the equipment it is assembled to,
always be sure that spring is in the "failed" or extended position. Remove any
accessory equipment that may cause the spring to be cocked. If there is any
doubt that the actuator is in the "failed" position, remove the air pressure from
the actuator and install a long threaded bolt (a bolt that exceeds the length of
the cylinder) in place of both travel stops. Once the actuator has been removed
from the equipment the long bolts must be removed first before the actuator can
be disassembled.
Repair or replace a damaged actuator immediately.
Inspect the vent valves on models 1480 – 2380 during regular maintenance
periods. The valves should allow leaking fluids to escape but prevent
contaminates from the surrounding atmosphere from entering the actuator.
Fluid leaking from the lower valve indicates a valve stem seal leak. Fluid leaking
from the upper valve indicates a leaking cylinder seal. If leakage is observed from
either valve disassemble and repair the source immediately. Never replace the
vent valves with plugs.
Operate the actuators within the pressure and temperature ranges specified
on the nameplate. Otherwise the actuator life may be reduced or serious safety
hazards may develop.
