Service Introduction
This Service section is designed to provide you, the customer, with the instructions needed to
properly maintain the MEC self-propelled aerial work platform. When used in conjunction with the
illustrated Parts section in this manual and the Operator’s Manual (provided separately), this manual
will assist you in making necessary adjustments and repairs, and identifying and ordering the correct
replacement parts.
All parts represented here are manufactured and supplied in accordance with MEC quality
standards. We recommend that you use genuine MEC parts to ensure proper operation and reliable
performance.
To obtain maximum benefits from your MEC Aerial Work Platforms, always follow the proper
operating and maintenance procedures. Only trained authorized personnel should be allowed to
operate or service this machine. Service personnel should read and study the Operator’s, and the
Service and Parts Manuals in order to gain a thorough understanding of the unit prior to making any
repairs.

MEC 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 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 warnings 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 relentless ongoing
efforts towards Continuous Improvement, due to which product specifications 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 operation. Proper safety
practices are the responsibility of the user and all operating personnel.
If there is a question on application and/or operation, contact MEC Aerial Work Platforms:

Safety Symbols & General Safety Tips
MEC manuals and decals use symbols, colors and signal words to help you recognize important
safety, operation and maintenance information.
RED and the word DANGER – Indicates an imminently hazardous
situation which, if not avoided, will result in death or serious injury.
ORANGE and the word WARNING – Indicates a potentially hazardous
situation which, if not avoided, could result in death or serious injury.
YELLOW with alert symbol and the word CAUTION – Indicates a
potentially hazardous situation which, if not avoided, may result in minor
or moderate injury.
YELLOW without alert symbol and the word CAUTION – Indicates a
potentially hazardous situation which, if not avoided, may result in
property damage.
GREEN and the word NOTICE – Indicates operation or maintenance
information.
Regular inspection and constant maintenance is the key to efficient economical operation 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. Correct 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 contamination
(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.

Hydraulic, Electrical and Total System
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 fluid 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 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.
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.

General Machine Maintenance
Instructions in this portion of the manual are to be used in conjunction with the Pre-Start, Frequent
and Annual Inspection checklists found in this machine’s Operator’s Manual.
IMPORTANT:Scheduled maintenance inspection checklists are included in the Operator’s
Manual for use only by qualified service technicians. Only qualified service
technicians may perform repairs to the machine. After repairs are completed,
the operator must perform a Pre-Start Inspection before proceeding to the
Functions 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
fitting immediately after disassembly to protect the system from outside
contamination (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 incompatible
lubricants may cause as much damage as no lubrication.
Watch for makeshift “fixes” which can jeopardize safety as well as lead to
more costly repair.
Inspection and maintenance should be performed by qualified personnel
familiar with the equipment.

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.
Maintaining the tires and wheels in good condition is essential to safe operation and good
performance. 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.
Check the tire surface and sidewalls for cuts, cracks, punctures and unusual wear.
Check each wheel for damage, bends and cracks.
Remove the wheel covers and check each center lock nut for proper torque and presence of
cotter pin.
