WARNING: Always keep hands and fingers away from bars of tilt linkage.
Remember that the load requires more vertical space when tilted
to the upright position, as well as more horizontal space when
tilted to the flat position. Make sure there is sufficient clearance
for the load to tilt without contacting the operator or any nearby
objects. If the lifter is equipped with the optional tilt lock, also
make sure it is either disengaged or locked out (see OPERATION:

: Using or Locking out the Optional Tilt
Lock). Then lift upward or press downward on the lower control
handles to tilt the load as desired. Since the tilt linkage is
designed to automatically maintain the load in either the upright
or the flat position, the load force on the control handles changes direction during the tilt. If load
size permits, maintain control with the handles throughout the tilt. For loads with overhang, it
may be necessary to release the control handles as the load approaches the flat position. If so,
keep the load under control using hand cups or other appropriate means.

WARNING: Load must be fully supported before releasing vacuum pads.
When the load is at rest and fully supported, move the lever on the vacuum control valve to the
“RELEASE” position: Pull outward on the lever's knob, move the lever all the way to the left and
then release it. This forces air into the vacuum pads, quickly breaking the vacuum seal. After
the pads have disengaged completely from the load, move the lifter away. Then place the lifter
in energy conservation mode as directed in the following discussion.
About Energy Conservation Mode
The lifter's vacuum control valve features a neutral position, designed to conserve battery energy
between lifts. To utilize this feature, pull outward on the lever's knob, move the lever to the
center position and then release it. Placing the valve lever in the center position closes off the
vacuum line that connects the vacuum pads to the vacuum generating system. As a result,
sufficient vacuum builds up in the line to turn off the low vacuum warning light and the vacuum
pumps
before the lifter is applied to another load. This reduces the amount of battery energy
needed to power the pumps and warning light.
WARNING: Never move valve lever to center position while lifter is supporting
load.
Energy conservation mode may only be used when the lifter is not supporting a load. The
operator must never move the valve lever to the center position while the lifter is supporting a
load, because this could result in a load release and possible injury to the operator.
