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.

shipping damage.
