A. Inspection
Inspect the actuator regularly to check:
• Any evidence of corrosion
• To make sure alignment is maintained relative to the load.
• That the actuator case has not been physically damaged.
• For excessive dirt and water entering actuator cases. (Clean
and correct as necessary).
• For evidence of loosening or shifting of parts due to vibration,
shock, wear or other conditions.
• Free action of brake and proper electrical release and holding
with no power.
• Any evidence of overheating.
• Any cracking or damage to wire joint and/or insulation.
• Any evidence of arcing or electrical shorts.
Under normal conditions, this inspection may be at intervals of
six months to a year. Where conditions are more severe, the
inspection should be at more frequent intervals as dictated by the
actual conditions. In all cases the consequences of a failure
should be a factor determining frequency of inspection or
servicing.
Always promptly check actuator in any case of malfunction or
erratic operation, and correct the cause.
B. Spare Parts
There has been no history of failure or weakness in any category
of parts which would dictate stocking of spares. Some users have
stocked items such as motors, capacitors, switches, gear trains,
complete actuators, or their combinations of parts and assemblies
depending upon their local conditions and requirements of
uninterrupted service.
When spare parts are required, include actuator model, and
description of part(s).
C. Repairs – Warranty Terms and Conditions
Before attempting repairs, modifications or addition of equipment
to the actuator by non-authorized personnel, the following
warranty terms and conditions should be reviewed.
Flowserve warrants its products against defects in materials and
workmanship for a period of one year from date of shipment from
its factory provided the equipment is properly installed and
operated. Liability is limited to repair, return of purchase price, or
replacement of any parts shown to be defective, and does not
extend to damage caused by accident, misuse, abuse, neglect,
tampering, or deterioration by corrosion. Products or parts not
manufactured by Flowserve are warranted only for the extent of
the original manufacturer’s warranty. There are no implied
warranties of fitness for a particular purpose. In no event shall
Flowserve be liable for loss of profits, loss by plant shutdown,
increased expense of operation, or other special or consequential

Should repair be necessary due to damage, wear, or malfunction,
identify any parts which may be required and contact your
McCANNA Ramcon Distributor or the factory. If it is necessary to
disassemble the actuator, observe proper orientation of all parts
and proper routing of all wires. Contact the factory for major
repair and RMA (Return Material Authorization) number.
