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
SPECIFICATIONS WITHOUT WRITTEN PERMISSION FROM MEC ARE STRICTLY
FORBIDDEN. A MODIFICATION MAY COMPROMISE THE SAFETY OF THE
MACHINE, SUBJECTING OPERATOR(S) TO SERIOUS INJURY OR DEATH.
MEC’s policies and procedures demonstrate our commitment to Quality and our relent-
less ongoing efforts towards Continuous Improvement, due to which product specifica-
tions are subject to change without notice.
Any procedures not found within this manual must be evaluated by the individual to
assure oneself that they are “proper and safe.”
Your MEC Aerial Work Platform 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.
MEC, as manufacturer, has no direct control over machine application and opera-
tion. Proper safety practices are the responsibility of the user and all operating
personnel.
If there is a question on application and/or operation contact:

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 oper-
ation of your aerial work platform. It will help to assure that your equipment will perform
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.
• 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.
M AINTENANCE L OCK
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.
Figure 1-1: Support Platform
1. Raise the platform approximately 7.2ft / 2.2m from the
ground.
2. Rotate the Maintenance Lock away from the machine
and let it hang down.
3. Lower the platform until the Maintenance Lock rests
securely on the link. Keep clear of the Maintenance
Lock when lowering the platform.

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
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 damage
to the electrical system, battery explosion, and personal injury.
T OTAL S YSTEM
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.
