INSTALLATION (CONT.)
17. Using a suitable lifting device, raise the lift to its
normal vertical position.
18. Bleed air from cylinder by cycling the mast to full
extension several times. The cylinder is self bleeding;
air will be forced out of the cylinder during the
lowering cycle.
19. If necessary, remove pinch shield and check align-
ment of cylinder within mast assembly by peering
down the mast with a flashlight. The cylinder guide
bearings must not be touching the inside surface of
#6 mast. The cylinder may be moved left or right
by tightening the left or right tie rod nuts respec-
tively.
Keep hands clear of the mast assembly
when the pinch shield is removed for
inspection purposes; pinching injury to
hands may result .
Never operate a machine with the pinch
shield removed, except for inspection.
