Allow for platform movement, electrical line sway
or sag, and beware of strong or gusty winds.
Keep away from the machine if it contacts
energized power lines. Personnel on the ground or
in the platform must not touch or operate the
machine until energized power lines are shut off.
Do not operate the machine during lightning or
storms.
Do not use the machine as a ground for welding.
Tip-over Hazards
Occupants, equipment and materials shall not
exceed the maximum platform capacity.
Maximum platform capacity 500 lbs 227 kg
Maximum platform capacity
Machine equipped with
Aircraft Protection Package 440 lbs 200 kg
Maximum occupants 2
The weight of options and accessories, such as
pipe cradles, panel cradles and welders, will
reduce the rated platform capacity and must be
factored into the total platform load. See the decals
on the options.
Do not raise or extend the boom unless the
machine is on a firm, level surface.
Do not depend on the tilt alarm as a level indicator.
The tilt alarm sounds in the platform only when the
machine is on a severe slope.

If the tilt alarm sounds while the boom is lowered:
Do not extend, rotate or raise the boom above
horizontal. Move the machine to a firm, level
surface before raising the platform.
If the tilt alarm sounds when the platform is raised:
Use extreme caution. Identify the condition of the
boom on the slope as shown below. Follow the
steps to lower the boom before moving to a firm,
level surface. Do not rotate the boom while
lowering.
If the tilt alarm sounds with the
platform uphill:
1 Lower the primary boom.
2 Lower the secondary boom.
3 Retract the primary boom.
If the tilt alarm sounds with the
platform downhill:
1 Retract the primary
boom.
2 Lower the secondary
boom.
3 Lower the primary
boom.
Do not alter or disable the limit switches.
Do not drive over 0.7 mph / 1 km/h with the primary
boom raised or extended or the secondary boom

Do not use the platform controls to free a platform
that is caught, snagged or otherwise prevented
from normal motion by an adjacent structure. All
personnel must be removed from the platform
before attempting to free the platform using the
ground controls.
Do not raise the boom when wind speeds may
exceed 28 mph / 12.5 m/s. If wind speeds exceed
28 mph / 12.5 m/s when the boom is raised, lower
the boom and do not continue to operate the
machine.

terrain, debris, unstable or slippery surfaces and
near holes and drop-offs.
Do not drive the machine on or near uneven
terrain, unstable surfaces or other hazardous
conditions with the boom raised or extended.
Do not drive the machine on a slope that exceeds
the maximum uphill, downhill or side slope rating of
the machine. Slope rating applies to machines in
the stowed position.
Maximum slope rating, stowed position
Counterweight uphill 35% 19°
Counterweight downhill 20% 11°
Side slope 25% 14°
Note: Slope rating is subject to ground conditions
and adequate traction.
Do not push off or pull toward any object outside
of the platform.

Pre-operation Inspection
Do Not Operate Unless:
You learn and practice the principles of safe
machine operation contained in this operator's
manual.
1 Avoid hazardous situations.
2 Always perform a pre-operation
inspection.
Know and understand the pre-operation
inspection before going on to the next
section.
3 Always perform function tests prior to use.
4 Inspect the workplace.
5 Only use the machine as it was intended.
Fundamentals
It is the responsibility of the operator to perform a
pre-operation inspection and routine maintenance.
The pre-operation inspection is a visual inspection
performed by the operator prior to each work shift.
The inspection is designed to discover if anything
is apparently wrong with a machine before the
operator performs the function tests.
The pre-operation inspection also serves to
determine if routine maintenance procedures are
required. Only routine maintenance items specified
in this manual may be performed by the operator.
Refer to the list on the next page and check each
of the items.
If damage or any unauthorized variation from
factory delivered condition is discovered, the
machine must be tagged and removed from
service.
Repairs to the machine may only be made by a
qualified service technician, according to the
manufacturer's specifications. After repairs are
completed, the operator must perform a
pre-operation inspection again before going on to
the function tests.
Scheduled maintenance inspections shall be
performed by qualified service technicians,
according to the manufacturer's specifications and
the requirements listed in the responsibilities
manual.

Operator's Manual Fifth Edition • Second Printing

Pre-operation Inspection
Be sure that the operator's, safety and
responsibilities manuals are complete, legible
and in the storage container located on the
platform.
Be sure that all decals are legible and in place.
See Decals section.
Check for hydraulic oil leaks and proper oil
level. Add oil if needed. See Maintenance
section.
Check for battery fluid leaks and proper fluid
level. Add distilled water if needed. See
Maintenance section.
Check the following components or areas for
damage, improperly installed or missing parts and
unauthorized modifications:
Electrical components, wiring and electrical
cables
Hydraulic power unit, reservoir, hoses,
fittings, cylinders and manifolds
Drive and turntable motors and drive hubs
Boom wear pads
Tires and wheels
Limit switches
Nuts, bolts and other fasteners
Platform entry mid-rail/gate
Beacon and alarms (if equipped)
PRE-OPERATION INSPECTION
Check entire machine for:
Cracks in welds or structural components
Dents or damage to machine
Be sure that all structural and other critical
components are present and all associated
fasteners and pins are in place and properly
tightened.
Be sure that both battery packs are in place,
latched and properly connected.
After you complete your inspection, be sure that
all compartment covers are in place and
latched.

Maintenance
Observe and Obey:
Only routine maintenance items specified in this
manual shall be performed by the operator.
Scheduled maintenance inspections shall be
completed by qualified service technicians,
according to the manufacturer's specifications
and the requirements specified in the
responsibilities manual.
Maintenance Symbols Legend
The following symbols have been
used in this manual to help
communicate the intent of the
instructions. When one or more of
the symbols appear at the
beginning of a maintenance
procedure, it conveys the meaning
below.
Indicates that tools will be required to
perform this procedure.
Indicates that new parts will be
required to perform this procedure.
Check the Hydraulic Oil Level
Maintaining the hydraulic oil at the proper level is
essential to machine operation. Improper hydraulic
oil levels can damage hydraulic components. Daily
checks allow the inspector to identify changes in oil
level that might indicate the presence of hydraulic
system problems.
1 Be sure that the boom is in the stowed position.
2 Check the hydraulic oil level.
Result: The hydraulic oil level should be,
between the FULL and ADD marks on the
hydraulic reservoir.
3 Add hydraulic oil if necessary.

Check the Batteries
Proper battery condition is essential to good
machine performance and operational safety.
Improper fluid levels or damaged cables and
connections can result in component damage and
hazardous conditions.
Electrocution/burn hazard. Contact
with hot or live circuits could result
in death or serious injury. Remove
all rings, watches and other
jewelry.
Bodily injury hazard. Batteries
contain acid. Avoid spilling or
contacting battery acid. Neutralize
battery acid spills with baking soda
and water.
Perform this test after fully
charging the batteries.
1 Put on protective clothing and eyewear.
2 Be sure that the battery cable connections are
tight and free of corrosion.
3 Remove the battery vent caps.
4 Check the battery acid level. If needed,
replenish with distilled water to the bottom of
the battery fill tube. Do not overfill.
5 Install the vent caps.
MAINTENANCE
Scheduled Maintenance
Maintenance performed quarterly, annually and
every two years must be completed by a person
trained and qualified to perform maintenance on
this machine according to the procedures found in
the service manual for this machine.
Machines that have been out of service for more
than three months must receive the quarterly
inspection before they are put back into service.
