JLG TF6-42 (9150-4003) Operator Manual - Manual (Page 30)

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.
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.
WARNING !
WARNING !
Always move boom to carry
position (horizontal or below)
before leveling frame. Attempting
to level machine with boom
raised could cause it to tip over.
