GMG OPERATOR POLICY
NOTE: The best method to protect yourself and others from injury or death is to use common sense. If
you are unsure of any operaon, don’t start unl you are sased that it is safe to proceed and have
discussed the situaon with your supervisor.
Service personnel and machine operators must understand and comply with all warnings and
instruconal decals on the body of the machine, at the ground controls, and plaorm control
console.
MODIFICATIONS OF THIS MACHINE FROM THE ORIGINAL DESIGN AND SPECIFICATIONS WITHOUT
WRITTEN PERMISSION FROM GMG ARE STRICTLY FORBIDDEN. A MODIFICATION MAY COMPRO-
MISE THE SAFETY OF THE MACHINE, SUBJECTING OPERATOR(S) TO SERIOUS INJURY OR DEATH.
GMG’s policies and procedures demonstrate our commitment to quality and our ongoing eorts
towards connuous improvement. Product specicaons are subject to change without noce.
Any procedures not found within this manual must be evaluated by the individual to assure oneself
that they are “proper and safe.”
Your GMG Aerial Work Plaorm has been designed, built, and tested to provide many years of safe,
dependable service. Only trained, authorized personnel should be allowed to operate or service the
machine.
GMG, as manufacturer, has no direct control over machine applicaon and operaon. Proper safety
pracces are the responsibility of the user and all operang personnel.

SAFETY SYMBOLS
To help you recognize important safety informaon, we have idened warnings and instrucons 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 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.
“Cauon” without alert symbol indicates a situaon which, if not avoided, may
result in property damage.

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.
