“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 potenally hazardous situaon which, if not avoided, may
result in minor or moderate injury. It may also be used to alert against unsafe pracces.

GENERAL SAFETY TIPS
MAINTENANCE LOCK
Regular inspecon and conscienous maintenance is the key to ecient economical operaon of your
aerial work plaorm. It will help to assure that your equipment will perform sasfactorily with a mini-
mum of service and repair.
The actual operang environment of the machine governs the inspecon schedule. Correct lubricaon
is an essenal part of the preventave maintenance to minimize wear on working parts and ensure
against premature failure. By maintaining correct lubricaon, the possibility of mechanical failure and
resulng downme is reduced to a minimum.
• Never leave hydraulic components or hoses open. They must be protected from contaminaon
(including rain) at all mes.
• 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 incompable lubricants may be as
harmful as no lubricaon.
• Watch for makeshi “xes” which can jeopardize safety as well as lead to more costly repair.
DEATH OR SERIOUS INJURY HAZARD!
NEVER PERFORM WORK OR INSPECTION ON THE MACHINE WITH THE PLATFORM ELEVATED WITHOUT
FIRST BLOCKING THE SCISSOR ASSEMBLY WITH THE MAINTENANCE LOCK.
1. Raise the plaorm approximately 7 / 2.1m from the
ground.
2. Rotate the Maintenance Lock away from the machine
and let it hang down.
3. Lower the plaorm unl the Maintenance Lock rests
securely on the link. Keep clear of the Maintenance
Lock when lowering the plaorm.

HYDRAULIC SYSTEM
HYDRAULIC FLUID UNDER PRESSURE CAN PENETRATE AND BURN SKIN, DAMAGE EYES, AND MAY
CAUSE SERIOUS INJURY, BLINDNESS, AND EVEN DEATH. CORRECT LEAKS IMMEDIATELY.
Hydraulic uid leaks under pressure may not always be visible. Check for pin hole
leaks with a piece of cardboard, not your hand.
ELECTRICAL SYSTEM
Prevent damage to baery and/or electrical system;
• Always disconnect the negave baery cable rst.
• Always connect the posive baery cable rst.
When the negave cable is installed, a spark will occur if contact is made between the posive side of
the baery and a metal surface on the machine. This can cause damage to the electrical system, baery
explosion, and personal injury.
TOTAL SYSTEM
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.

Instrucons in this poron of the manual are to be used in conjuncon with the Pre-Start, Frequent and
Annual Inspecon checklists found in this machine’s Operator’s Manual.
IMPORTANT:Scheduled maintenance inspecon checklists are included in the Operator’s Manual for
use only by qualied service technicians. Only qualied service technicians may perform repairs to
the machine. Aer repairs are completed, the operator must perform a Pre-Start Inspecon before
proceeding to the Funcons Test.
HYDRAULIC FLUID UNDER PRESSURE CAN PENETRATE AND BURN SKIN, DAMAGE EYES, AND MAY
CAUSE SERIOUS INJURY, BLINDNESS, AND DEATH. REPAIR LEAKS IMMEDIATELY. FLUID LEAKS
UNDER PRESSURE MAY NOT ALWAYS BE VISIBLE. CHECK FOR PIN HOLE LEAKS WITH A PIECE OF
CARDBOARD, NOT YOUR HAND.
NEVER PERFORM WORK OR INSPECTION ON THE MACHINE WITH THE PLATFORM ELEVATED
WITHOUT FIRST BLOCKING THE SCISSOR ASSEMBLY WITH THE MAINTENANCE LOCK (SEE THE
INTRODUCTION PORTION OF THIS MANUAL).
PERFORM SCHEDULED MAINTENANCE AT RECOMMENDED INTERVALS. FAILURE TO PERFORM
SCHEDULED MAINTENANCE AT RECOMMENDED INTERVALS MAY RESULT IN A DEFECTIVE OR
MALFUNCTIONING MACHINE AND MAY RESULT IN INJURY OR DEATH OF THE OPERATOR. KEEP
MAINTENANCE RECORDS CURRENT AND ACCURATE.
IMMEDIATELY REPORT ANY DAMAGE, DEFECT, UNAUTHORIZED MODIFICATION OR MALFUNCTION
TO YOUR SUPERVISOR. ANY DEFECT MUST BE REPAIRED PRIOR TO CONTINUED USE. DO NOT USE A
DAMAGED, MODIFIED OR MALFUNCTIONING MACHINE.
Never leave hydraulic components or hoses open. Plug all hoses and
ng immediately aer disassembly to protect the system from outside contaminaon (including
rain).
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 incompable lubricants may cause as
much damage as no lubricaon.
Watch for makeshi “xes” which can jeopardize safety as well as lead to more costly repair.
Inspecon and maintenance should be performed by qualied personnel familiar with the
equipment.

PRE-START INSPECTION CHECKLIST
PRE-START INSPECTION CHECKLIST
Items on this checklist should be inspected before each work shift. Refer to the Operator’s
Manual.
30-DAY SERVICE
The 30 day maintenance procedure is a one-time procedure to be performed after the first 30
days or 40 hours of usage. This procedure is normally performed every 150 hours or quarterly,
whichever comes first.
Maintaining the tires and wheels in good condition is essential to safe operation and good per-
formance. Tire and/or wheel failure could result in a machine tip-over.
Component damage may also result if problems are not discovered and repaired in a timely
fashion.
1. Check the tire surface and sidewalls for cuts, cracks, punctures and unusual wear.
2. Check each wheel for damage, bends and cracks.
3. Remove the wheel covers and check each center lock nut for proper torque.
Castle nut torue, dry 19 -lbs / 26 Nm
Castle nut torque, lubricated 14 -lbs / 20 NM
FREQUENT INSPECTION CHECKLIST
THIS CHECKLIST MUST BE USED AT 3-MONTH INTERVALS OR EVERY 150 HOURS OF MACHINE
USE, WHICHEVER OCCURS FIRST. FAILURE TO DO SO COULD RESULT IN DEATH OR SERIOUS
INJURY.
Frequent Maintenance Inspecons should be conducted by qualied service technicians only. Pho-
tocopy the Frequent Inspecon Checklist page from the Operator’s Manual to keep record of this in-
specon. Keep inspecons records up to date. Record and report all discrepancies to your supervisor.
Perform all checks listed on Pre-Start Inspecon, then proceed with the following checks.

FREQUENT INSPECTION CHECKLIST
BATTERIES
Proper battery condition is essential to good machine performance and operational safety.
Improper or damaged cables and connections can result in component damage and hazardous
conditions.
ELECTROCUTION / BURN HAZARD. CONTACT WITH ELECTRICALLY CHARGED 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.
1. Put on protective clothing and eye wear.
2. Slide out the component tray from the chassis.
3. Be sure that the battery cable connections are free of corrosion.
NOTE: Adding terminal protectors and a corrosion preventative sealant will help elimi-
nate corrosion on the battery terminals and cables.
4. Be sure that the battery retainers and cable connections are tight.
5. Fully charge the batteries. Allow the batteries to rest 24 hours before performing this
procedure to allow the battery cells to equalize.
6. Check each battery pack and verify that the batteries are wired correctly.
7. Inspect the battery charger plug and pigtail for damage or excessive insulation wear.
Replace as required.
8. Connect the battery charger to a properly grounded 110 - 230V / 50 - 60 Hz single phase
AC power supply.
• Result: The charger should operate and begin charging the batteries.
• Result: If, simultaneously, the charger alarm sounds and the LEDs blink, correct the
charger connections at the fuse and battery. The charger will then operate
correctly and begin charging the batteries.
NOTE: For best results, use an extension cord of adequate size with a length no longer
than 50 ft / 15m.
If you have any further questions regarding the battery charger operation, please contact
the GMG Customer Service.
