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.

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.

MACHINE MAINTENANCE – GENERAL
M ACHINE M AINTENANCE – G ENERAL
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.

PRE-START INSPECTION CHECKLIST
P RE -S TART I NSPECTION C HECKLIST
Items on this checklist should be inspected before each work shift. Refer to the
Operator’s Manual.
30-D AY S ERVICE
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 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.
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.
F REQUENT I NSPECTION C HECKLIST
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 Inspections should be conducted by qualified service
technicians only. Photocopy the Frequent Inspection Checklist page from the
Operator’s Manual to keep record of this inspection. Keep inspections records up to
date. Record and report all discrepancies to your supervisor.
Perform all checks listed on Pre-Start Inspection, then proceed with the following
checks.
H YDRAULIC F LUID
Inspect the condition of hydraulic fluid in the reservoir.
Oil should be a clear and amber in color.

FREQUENT INSPECTION CHECKLIST
B ATTERIES
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 eliminate 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 charg-
ing 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 MEC Customer
Service.
