UL-32,40 (STANDARD)

The UL32 and UL40 are equipped with a castered rear
Tilt Back assembly. When the unit is tilted back onto
this support frame, the overall height is reduced to allow
the unit to pass through a standard doorway.

Lowering

Before tilting the machine onto the rear
Tilt Back assembly be sure the retaining
pin is fully inserted with the hair pin re-
tainer installed and the cylinder assembly
is fully extended.
DO NOT drop Tilt Back frame.
Keep out from under Tilt Back frame and
machine when tilting.
1. Be sure area is clear of personnel and obstructions.
2. While holding Tilt Back frame, remove the hair pin
retainer and the retaining pin (fig. 3-11).
3. Lower the Tilt Back frame until the hole in the
cylinder assembly aligns with the upper mounting
bracket pin hole. Secure the cylinder assembly to
the upper mounting bracket using retaining pin and
hair pin retainer (fig. 3-11).
4. Extend Tilt Back Handle to the tilt/lift position by
releasing locking pin and pulling handle out of the
Tilt Back assembly until the locking pin engages
(fig. 3-12).
5. Push down on the Tilt Back Handle until the unit
comes to rest on the Tilt Back frame. As the mast tilts
back, counterbalance the machine's weight by
increasing upward force on end of Tilt Back Handle
(fig. 3-12). This allows machine to gently come to rest
on Tilt Back casters.
