Leveling
The handler is designed to permit tilting main frame
eight degrees to left or right to compensate for
uneven ground conditions.
A level indicator located on upper portion of front
window frame to permit operator to determine that
machine is or is not level.
The rear axle pivots at the midpoint of the main
frame to help assure that wheels will remain in
contact with ground. A hydraulic cylinder provides
a rigid connection between front axle and main
frame to help assure a solid work platform and
permit tilting main frame to left or right.
NOTE: The frame leveling function is provided only
to level the machine before lifting or placing a load.
Do not attempt to use leveling feature to turn on or
travel across a slope.
Boom
The three section hydraulically operated boom
provides maximum reach of 36 feet above
horizontal at 70° elevation and 21 feet forward of
forward edge of front tires at 0° elevation (measured
to heel of standard forks mounted on standard
carriage). Boom travel extends from 4° below Extend
horizontal to 70° above horizontal.
Raise boom by pulling boom lever to rear and lower
boom by pushing boom lever forward.
Boom extension and retraction is accomplished by a
hydraulic crowd cylinder anchored at rear of boom
section no. 1 and at front of boom section no. 2 and
also by a cable and push beam arrangement within
the boom sections. Extension or retraction of
boom section no. 2 is always equaled by a
corresponding movement of boom section no.
3.
A hydraulic cylinder is located within the boom
head to tilt the fork carriage or other attachment
back and forth as required.
MATERIAL HANDLING
Raising the boom (loaded or unloaded)
when handler is leaning to the side can
cause machine to tip over with little or no
warning.
To Level Handler:
The tilt cylinder is controlled by carriage tilt/
machine level lever. Push lever forward to tilt
attachment down or pull lever to rear to tilt
attachment up.
Extend boom by moving boom lever to right and
retract boom by moving boom lever to left.
A compensating cylinder is pinned to main frame
and to base of boom section no. 1. As boom is
raised, oil is transferred from rod end of
compensating cylinder to rod end of attachment tilt
cylinder. Lowering boom causes transfer of oil from
barrel end of compensating cylinder to barrel end of
attachment tilt cylinder. This transfer of oil causes
extension and retraction of tilt cylinder to maintain
angle of attachment as boom is raised and lowered.
All cylinders related to boom (attachment tilt, raise/
lower and extend/retract) are protected by pilot
operated check valves which prevent load from
falling in event of a broken hydraulic hose or tube.
Position machine in best location to lift or place
load and apply brake.
Observe level indicator to determine whether
machine must be leveled. Note position of
indicator for later realignment.
If necessary, position boom in carry position and
move carriage tilt/machine level lever to left or
right to level machine. Move lever to left to lower
left side of frame or move lever to right to lower
right side of frame.
Lift or place load as appropriate.
Retract and lower boom to carry position.
Realign frame to position noted in step 2.

If handler cannot be leveled using leveling
if handler cannot be leveled using leveling
system, do not attempt to raise or place
load. Have surface leveled.
