NOTE: The best method to protect yourself and others from injury or death is to use common sense. If you are unsure
of any operation, don’t start until you are satisfied that it is safe to proceed and have discussed the situation with
your supervisor.
Service personnel and machine operators must understand and comply with all warn-
ings and instructional decals on the body of the machine, at the ground controls, and
platform control console.
MODIFICATIONS OF THIS MACHINE FROM THE ORIGINAL DESIGN AND

S AFETY S YMBOLS
To help you recognize important safety information, we have identified warnings and instructions
that directly impact on safety with the following signals:
“DANGER” INDICATES AN IMMINENTLY HAZARDOUS SITUATION WHICH, IF
NOT AVOIDED, WILL RESULT IN DEATH OR SERIOUS INJURY.
THIS SIGNAL WORD IS LIMITED TO THE MOST EXTREME SITUATIONS.
“WARNING” INDICATES A POTENTIALLY HAZARDOUS SITUATION WHICH, IF
NOT AVOIDED, COULD RESULT IN DEATH OR SERIOUS INJURY.
“CAUTION” indicates a potentially hazardous situation which, if not avoided, may
result in minor or moderate injury. It may also be used to alert against unsafe
practices.
“Caution” without alert symbol indicates a situation which, if not avoided, may
result in property damage.

G ENERAL S AFETY T IPS
Regular inspection and conscientious maintenance is the key to efficient, economical
operation of your aerial work platform. It will help to assure that your equipment will per-
form satisfactorily with a minimum of service and repair.
The actual operating environment of the machine governs the inspection schedule. Cor-
rect lubrication is an essential part of the preventative maintenance to minimize wear on
working parts and ensure against premature failure. By maintaining correct lubrication, the
possibility of mechanical failure and resulting downtime is reduced to a minimum.
M AINTENANCE T IPS
• Never leave hydraulic components or hoses open. They must be protected from contamina-
tion (including rain) at all times.
• Never open a hydraulic system when there are contaminants in the air.
• Always clean the surrounding area before opening hydraulic systems.
• Use only recommended lubricants. Improper lubricants or incompatible lubricants may be as
harmful as no lubrication.
• Watch for makeshift “fixes” which can jeopardize safety as well as lead to more costly repair.

S ETTING T HE M AINTENANCE C HOCK
NEVER PERFORM WORK OR INSPECTION ON THE MACHINE WITH THE
PLATFORM ELEVATED WITHOUT FIRST BLOCKING THE BOOM ASSEMBLY
WITH THE MAINTENANCE CHOCK.
THE MAINTENANCE CHOCK IS HEAVY. HOLD IT SECURELY DURING THE
INSTALLATION AND REMOVAL PROCESS.
THE MAINTENANCE CHOCK MAY ROTATE AROUND THE CYLINDER ROD
DURING MACHINE MOVEMENT AND MAY FALL IF IT IS NOT HELD SECURELY
IN PLACE DURING INSTALLATION AND REMOVAL.
The Maintenance Chock fits over the lift cylinder rod, between the rod end and the end
of the cylinder barrel.
I NSTALLATION
Figure 1-1: Maintenance Chock Stowage
• Remove the Maintenance Chock
from the tool storage compart-
ment of the Engine Module.
• Using the Boom Lift/Lower func-
tion, raise the platform to
approximately 13 feet (4 m).
• Place the Maintenance Chock
over the cylinder rod above the
cylinder barrel.
• Using the Boom Lift/Lower func-
tion, slowly lower the boom until
the Maintenance Chock is secure between the cylinder rod end and the cylinder barrel.
R EMOVAL
• Using the Boom Lift/Lower function, raise the platform to approximately 13 feet
(4 m) until the Maintenance Chock moves freely.
• Remove the Maintenance Chock from the cylinder rod.
• Store the Maintenance Chock in the tool storage compartment of the Engine Module.

H YDRAULIC S YSTEM
HYDRAULIC FLUID UNDER PRESSURE CAN PENETRATE AND BURN SKIN,
DAMAGE EYES, AND MAY CAUSE SERIOUS INJURY, BLINDNESS, AND EVEN
DEATH.
CORRECT LEAKS IMMEDIATELY.
Hydraulic fluid leaks under pressure may not always be visible. Check for pin hole
leaks with a piece of cardboard, not your hand.
E LECTRICAL S YSTEM
To prevent damage to battery and/or electrical system:
• Always disconnect the negative battery cable first.
• Always connect the positive battery cable first.
When the negative cable is installed, a spark will occur if contact is made between the
positive side of the battery and a metal surface on the machine. This can cause electrical
system damage, battery explosion, and personal injury.
T OTAL S YSTEM
ENGINE COOLANT LEVEL MUST BE CHECKED ONLY AFTER ENGINE HAS
COOLED. IF RADIATOR CAP IS REMOVED WHILE THE COOLANT IS AT NORMAL
OPERATING TEMPERATURE, PRESSURE WITHIN THE COOLANT SYSTEM WILL
FORCE HOT LIQUID OUT THROUGH THE FILLER OPENING AND MAY CAUSE
SEVERE SCALDING.
Failure to perform preventive maintenance at recommended intervals may result
in the unit being operated with a defect that could result in injury or death of the
operator.
Immediately report to your supervisor any defect or malfunction. Any defect
shall be repaired prior to continued use of the aerial work platform.
Inspection and maintenance should be performed by qualified personnel
familiar with the equipment.

IF THE CONTROL SYSTEM FAILS WHILE THE PLATFORM IS ELEVATED, USE
THE EMERGENCY LOWERING PROCEDURE TO SAFELY LOWER THE
PLATFORM.
DO NOT CLIMB DOWN THE BOOM ASSEMBLY OR EXIT THE PLATFORM.
The Emergency Lowering System is used to lower the platform in case of power failure.
To lower the platform, activate the Emergency Power Switch to run the Emergency
Down auxiliary hydraulic pump.
This function uses battery power from the auxiliary battery to lower the platform.
• Push and hold the Emergency Power Switch, then use the Boom Extend/Retract function to
retract the boom.
• Continue to hold the Emergency Power Switch, then use the Boom Lift/Lower function to
lower the boom.
NOTE: The Emergency Lowering System overrides the engine function. The engine will shut off when the Emergency
Power Switch is engaged.
The Emergency Power Switch serves as an enable switch. It is not necessary to use the primary function

DEATH OR SERIOUS PERSONAL INJURY MAY RESULT FROM THE USE OF
SUBSTANDARD LIFTING DEVICES AND/OR JACK STANDS. ENSURE THAT ALL
LIFTING DEVICES AND JACK STANDS ARE OF ADEQUATE CAPACITY AND IN
GOOD WORKING CONDITION BEFORE USE.
The following are needed to safely lift and support the machine;
• a jack with a lifting capacity of seven (7) tons or more.
• jack stands with a rating of seven (7) tons or more.
T O RAISE THE MACHINE
1. Move machine to a firm level surface capable of supporting the weight of the
machine.
2. Chock the tires on the end of machine opposite the end to be raised.
3. If wheel is to be removed, break loose but do not remove lug nuts before raising the
machine.
4. Position a jack at the end of the machine to be lifted, under a solid lifting point in the
center of the frame.
5. Raise the machine and place two (2) suitable jack stands under solid support points
at the outer ends of the frame.
6. Lower the machine to rest on the jack stands and inspect for stability.
T O LOWER THE MACHINE
1. Tighten lug nuts to hold the wheel snug to the hub. Do not torque the lug nuts at this
time.
2. Raise machine slightly and remove jack stands.
3. Lower the machine and remove the jack.
4. Tighten lug nuts to proper torque (refer to machine specifications).
5. Remove chocks.
