Do not use as a personnel lifting platform or step.
Do not stand on the forks.
Do not climb on the mast.
Tip-over Hazards
Donot operatea GenieSuper Towerunless allfour
outriggersareproperlyinstalledin thebase
sockets, the screw jack pads are in firm contact
with the ground and the base is level.
Donot operate themachine unlessalloutrigger
lock pins are in place and properly inserted into
eachoutrigger.
Do not raise the load unless the machine is level.
Do not set the machine up on a surface where it
cannot be leveled using only the leveling jacks.
Do not move the machine
with a raised load, except
forminorpositioning.
Do not leave the load
raisedwiththeoutrigger
casters contacting the
ground.
Do not adjust or remove
theoutriggerswhilethe
load is raised.
Do not operate the machine in strong or gusty
winds. Increasing the load surface area will
decrease machine stability in windy conditions.

Pre-operation Inspection
Fundamentals
Thepre-operation inspection is a visualinspection
performed by the operator prior to each work shift.
This inspection is designed to discover if anything
isapparently wrongwitha machinebefore the
operator performs the function tests.
Refer to the list on the next page and check each
of the items.

FUNCTIONTESTS
Function Tests
1 Position the machine at the desired work site.
Setup
1 Removetheoutriggersfromtheoutrigger
storage sockets.
2 Lay each outrigger near the base where it is to
be installed. The two long outriggers will be
installed into the two front base sockets. The
two short outriggers will be installed into the two
rear base sockets.
3 Select any outrigger. Slide the outrigger all the
way into the base socket until the outrigger lock
pin snaps into the outrigger, locking it in place.
Repeatforeachremainingoutrigger.
4 Adjust the outrigger screw jacks until the base
casters are slightly off the ground.

the following safety rules:
· Make sure the area is level and clear of
obstructions
· Make sure the load is centered on the load
handlingattachment
· Make sure the load is properly secured to the
loadhandlingattachment
· Avoid sudden starts and stops
· Travel with the load in the lowest possible
position
· Keeppersonnelawayfromthemachineand

Load Capacity Charts
Observe and Obey:
Failure to properly position the load may result in
deathor seriousinjury.
Verify that the load you wish to raise does not
exceed the maximum load for your load center.
See the Load Capacity Chart on the next page.
Tip-overhazard.Raisingaload
that exceeds the machine capacity
may result in death or serious
injury.
A load center is defined as the balancing point
(center of gravity) of a load and must be
positionedwithin theload center zone.

Load Positioning Instructions
1 Determine the weight of the load and the
location of its load center.
2 Measure to the load center from the side of the
load that will be closest to the carriage.
3 Refer to the chart on the next page to determine
if the machine is capable of lifting the weight at
the location on the forks.
4 Place the load so that it rests on the forks, as
close to the carriage as possible.
5 Position the load so that the load center is within
the load center zone.
6 Secure the load to the forks.
