3.
Attach mounting accessories to the electric cylinder; see
Tighten the fastening screws evenly.
4.
Attach rod-end accessories and the workload.
Be sure the workload center of gravity is centric to the piston rod.
When fastening a rod-end accessory or workload to the piston rod, use two wrenches.
Use one wrench to tighten the mounting nut or rod-end accessory and the other, on the
piston-rod wrench flats, to counteract the applied torque. Be sure that the torque is not
applied to the piston rod and that the piston rod does not rotate.

ATTENTION: Damage may occur to the electric cylinder bearings and the feedback
device if sharp impact to the piston rod is applied during installation. Do not strike the
piston rod with tools during installation or removal.
Failure to observe these safety precautions could result in damage to the electric cylinder
and its components.
IMPORTANT
Do not twist or rotate the piston rod. If the piston rod is rotated, the absolute position
of the electric cylinder will be lost and the absolute home position must be
re-established.

ATTENTION: Do not rotate the piston rod during installation.
Rotating the piston rod will break the mechanism that lets the
electric cylinder extend and retract. Use two wrenches to install
the workload.
