Unpacking

While unpacking the actuator, check packing list against

materials received. Lists describing the actuator and

accessories are included in each shipping container.

1. Position the lifting straps and hoist to avoid damage

to the tubing and mounted accessories when lifting

the actuator from the shipping container.

WARNING: When lifting an actuator with lifting

straps through the yoke legs, be aware the

center of gravity may be above the lifting point.

Therefore, support must be given to prevent the

actuator from rotating or causing serious injury

to personnel or damage to nearby equipment.

2. Contact your shipper immediately in the event of

shipping damage.

3. Contact your Flowserve representative with any

problems.
