Use two wrenches to attach a rod-end accessory: one wrench to tighten the rod-end
accessory, and the other wrench to counter act the applied torque at the thrust-rod
wrench flats.
6. Use these torque values to attach an anti-rotation guide to the cylinder and the thrust
rod.
To reduce wear on the horizontal guides of the Anti-rotation kit, adjust the guides at the
work load and the electric cylinder so that they are exactly parallel, as described in Mount
the Electric Cylinder on page 13 .
ATTENTION: Do not apply torque or rotate the thrust rod itself. Rotating the thrust rod
will cause the home position to be lost.
