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.
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.

Maintenance Safety
Make sure that a chock is used during when working under an elevated
platform.
NEVER perform work on the machine with the platform elevated without first using a 2”×4” to support
the mast section as is shown below. Alternatively the platform can be supported with either a forklift or
a crane.

Electrical System and Total System
Electrical System
Prevent damage to battery and/or electrical system;
Always disconnect the negative battery cable first.
Always connect the positive battery cable last.
•
•
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.

ART_5803B
Fully lower the platform. The platform must remain lowered during all loading and transport
procedures.
Position the forklift forks in position as the figure above.
Drive forward to the full extent of the forks.
Raise the machine 6 in (15 cm) and then tilt the forks back slightly to keep the machine secure.
Be sure the machine is level when lowering the forks.
Lifting Instructions
Fully lower the mast and jib boom. Remove all loose items on the machine.
Attach the rigging only to the designated lifting points on the machine. There
are two lifting points on the top of the mast.
Adjust the rigging to prevent damage to the machine and to keep the machine
level.

Check the following components or areas for damage, improperly installed or missing parts and
unauthorized modifications:
Electrical components, wiring and electrical cables
Battery and connections
Drive motors
Wear pads
Wheels
Lifting chains and idler wheels
Mast and mast braces
Limit switches, alarms and horn

manual is included with each machine. An illegible or missing manual will not provide safety and
operational information necessary for a safe operating condition.
In addition, maintaining all of the safety and instructional decals in good condition is mandatory
for safe machine operation. Decals alert operators and personnel to the many possible hazards
associated with using this machine. They also provide users with operation and maintenance
information. An illegible decal will fail to alert personnel of a procedure or hazard and could result in
unsafe operating conditions.
Check to make sure that the operator’s manual is present and complete in the storage container
on the platform.
Examine the pages of the manual to be sure that they are legible and in good condition.
Result: The operator’s manual is appropriate for the machine and the manual is legible and
in good condition.
Result: The operator’s manual is not appropriate for the machine or the manual is not in
good condition or is illegible. Remove the machine from service until the manual is replaced.
Open the operator’s manual to the decals inspection section. Carefully and thoroughly inspect all
decals on the machine for legibility and damage.
Result: The machine is equipped with all required decals, and all decals are legible and in
good condition.
Result: The machine is not equipped with all required decals, or one or more decals are
illegible or in poor condition. Remove the machine from service until the decals are replaced.
Always return the manual to the storage container after use.
2) Perform Pre-operation Inspection
Completing a Pre-operation Inspection is essential to safe machine operation. The Pre-operation
Inspection is a visual inspection performed by the operator prior to each work shift. The inspection
is designed to discover if anything is apparently wrong with a machine before the operator performs
the function tests. The Pre-operation Inspection also serves to determine if routine maintenance
procedures are required.
Complete information to perform this procedure is available in the appropriate operator’s manual.
Refer to the Operator’s Manual for your machine.
3) Perform Function Tests
Completing the function tests is essential to safe machine operation. Function tests are designed
to discover any malfunctions before the machine is put into service. A malfunctioning machine must
never be used. If malfunctions are discovered, the machine must be tagged and removed from
service.
Complete information to perform this procedure is available in the appropriate operator’s manual.
