Gradall 534B-9 Operation Manual - Manual (Page 20)

“LEVELING” means positioning the handler so that
it is level from side to side (left to right with respect to
a m a n s i t t i n g i n o p e r a t o r ’s s e a t ) .
A level indicator is located on upper portion of front
window frame to permit operator to determine that
h a n d l e r f r a m e i s , o r i s n o t , l e v e l .
There are four very important things to remember
about handler travelling:
Never engage a load or lift a load more than four
feet above ground level unless the handler is level.
A handler with the boom raised and/or an attach-
ment installed is a partially loaded handler.
Once the handler frame has been leveled, and has
raised a load more than four feet above ground
level, it must not be moved from its position if
such movement could change the level condition.
The combination of side tilt and load can cause the
handler to tip over.
T h e r e a r e t w o w a y s t o l e v e l t h e h a n d l e r :
The surface which will support the handler can be
leveled. This method must be chosen if it will be
necessary to move the handler from its position
after the load has been raised over four feet from
ground level -
AND - such movement could
c ha n g e t he leve l condi t io n.
Remember, the supporting surface must be large
enough , smooth enough and firm enough to keep
handler level when it is moved from its position.
The handler may be leveled by means of the frame
leveling system. This method may be chosen when
it will not be necessary to move the handler from
its position after the load has been raised above
four feet from ground level - OR - when such
movement will not change the level condition of
the handler.
LEVELING THE HANDLER
Leveling Handler Frame:
The handler is designed to permit tilting main frame
eight degrees to left or right to compensate for
uneven ground conditions.
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.
Procedure:
Position machine in best location to lift or place
load and apply parking brake.
Observe level indicator to determine whether
machine must be leveled. Note position
indicator for later realignment.
If necessary to level handler, position boom in
carry position and move machine level lever to
level machine.
Lift or place load as appropriate.
Retract and lower boom to carry position.
Realign frame to position noted in step 2.
FRAME
LEVELING LEVER
If handler cannot be leveled using leveling
system, do not attempt to raise or place
load. Have surface leveled.

Always determine best positions for handler to raise
load from its present location and also to position
load at its destination.
THEN , determine which
method of leveling will be required at each location.
FINALLY , consider terrain between present location
of load and its destination.Never attempt to transport
a load across terrain which could cause handler to tip
over.

Raising the boom (loaded or unloaded)
when handler is leaning to the side can
cause machine to tip over with little or no
warning and cause serious injury or death.
