4. Attach rod-end accessories and the work load.
Be sure the work load center of gravity is centric to the piston rod.
When fastening a rod-end accessory or work load 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 counter act the applied torque. Be sure that the torque is not
applied to the piston rod and that the piston rod does not rotate.
If you are using a coupling piece attachment, catalog number MPAR-NE3612
x, or
trunnion mounting kit, catalog number MPAR-NA1635
xx, see
for torque values.
If you are using a rod guide accessory, catalog number MPAR-NE34
xxx or
MPAR-NE150
xxx, adjust the guides of the work load and the electric cylinder so that
they are exactly parallel. This avoids excessive wear on the guide.
ATTENTION: Damage can 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 is lost and the absolute home position must be re-established.

ATTENTION: Do not rotate the piston rod during installation. Rotating the
piston rod breaks the mechanism that lets the electric cylinder extend and
retract. Use two wrenches to install the work load.
Failure to observe these safety precautions could result in damage to the
electric cylinder and its components.
