PASSAGE THROUGH A DOORWAY
The UL machine is 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 unto the rear tilt back as-
sembly, be sure that the retaining pin is fully inserted
with the hair pin retainer 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. Ensure 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 retain-
ing 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 handle.
RAISING
1. Lift up on the mast handle to extend the cylinder assembly.
2. Fully engage the tilt back handle until the locking pin engages.
3. Lift up on the tilt back handle.
• As the mast approaches vertical, counterbalance the machine’s weight by increasing
downward force on the end of the tilt back handle. This allows the machine to settle gently
on the front casters.
4. Return the tilt back handle to the storage position, making sure that the locking pin engages
the handle.
5. While holding the tilt back frame, remove the retaining pin and raise the tilt back assembly to
the stowed position.
