NSTALLATION
Note: before installing Upper Lift Cylinder check cylinder pins and bearings for wear and
replace if necessary.
1. Lift the cylinder into place and insert the body end pin in through the cylinder and Second Post
Anchors.
Note: take care in aligning the pin in the holes so that the pin can be pushed in by hand. If
the pin and holes are not properly aligned and the pin is forced in, the bushings will be
damaged.
2. Line the Upper Boom Anchor holes up with the cylinder rod hole and insert the rod end pin.
(Note: To align the holes use an overhead crane and sling of suitable capacity firmly secured to
the Upper Boom at the cage end. This should be used to raise and lower the Upper Boom).
3. Slide both locking plates into the groves on the pins and secure with the bolts and washers.
4. Reconnect the hoses to their correct ports.
5. Test with weight at rated platform load to check system operation.
