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.

Before tilting the machine onto the rear Tilt Back assembly, be sure that the retaining pin is fully inserted
with the hair pin retainer installed and the cylinder assembly is fully extended.
DO NOT drop the Tilt Back frame.
Keep out from under the Tilt Back frame and machine when tilting.
1. Be sure that the area is clear of personnel and obstructions.
2. While holding the Tilt Back frame, remove the hair pin retainer and the retaining pin.
3. Lower the Tilt Back frame until the hole in the cylinder assembly align with the upper mounting bracket
pin hole. Secure the cylinder assembly to the upper mounting bracket using the retaining pin and hair pin
retainer.
4. Extend the Tilt Back Handle to the tilt/lift position by releasing the locking pin and pulling the handle out
of the Tilt Back assembly until the locking pin engages.
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 the end of
the Tilt Back Handle. This allows the machine to gently come to rest on the Tilt Back casters.
6. Pull down on the handle on the back of the mast to compress the cylinder assembly.
7. Return the Tilt Back Handle to the storage position, making sure that the locking pin engages the han-
dle.
