JLG G9-43A (9151-4003) Operator Manual - Manual (Page 34)

WARNING !
If handler cannot be leveled using
leveling system, do not attempt to
raise or place load. Have surface
leveled.
“Leveling” means positioning the handler so that it is level from side to side
(left to right). A level indicator is located in upper right corner of front window
frame to permit operator to determine whether the handler frame is level.
There are four very important things to remember about handler
leveling:
1. Never engage a load or lift a load more than 1.2m (four feet) above
ground unless handler is level.
2. A handler with the boom raised and/or an attachment installed is a
partially-loaded handler.
3. Once the handler frame is level and the operator has raised a load
more than 1.2m (four feet) above ground, it must not be moved from this
position if such movement could change the level condition. Do not use
sway to level handler with load more than 1.2m (four feet) above ground.
4. The combination of side tilt and load could cause the handler to tip over.
Level the handler:
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 1.2m (four feet) from ground AND such movement
could change the level condition.
Remember: The supporting surface must be large enough, smooth enough
and firm enough to keep the 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 1.2m (four feet) from ground - OR
- when such movement will not change the level condition of the handler.
Always determine best position 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.
Leveling Handler Frame:
The handler is designed to permit tilting main frame 10° to left or right to
compensate for uneven ground conditions.
Optional rear-axle stabilization is available for Material Handlers covered by
this manual. This system includes a hydraulic cylinder attached to the frame
and the rear axle, as well as flow-restricting valving. This system dampens
rear-axle oscillation whenever the boom is raised over 45° from level. However,
the system never locks the rear axle and is not designed to increase
lateral stability.
Leveling Procedure:
Position machine in best location to lift or place load, position forward/
reverse lever in neutral and apply parking brake. Observe level indicator to
determine whether machine must be leveled and level machine with the
machine level lever.
LEVELING THE HANDLER
11.0
Raising the boom (loaded or
unloaded) when handler is leaning
to one side could cause machine
to tip over with little or no warning
and cause serious injury or death.
