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.

Key Safety Tips
NEVER PERFORM SERVICE ON THE MACHINE WITH THE PLATFORM
ELEVATED WITHOUT FIRST SUPPORTING THE PLATFORM/BOOM
ASSEMBLY.
Use a crane with chains and straps of
adequate lifting capacity to support the
platform.
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.

January 2019Section 4 - General Information 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
Engine coolant level must be checked only after engine has cooled.
If radiator cap is removed while the coolant is at normal operating
temperature, pressure within the coolant system will force hot liquid out
through the filler opening and may cause severe scalding.
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.

PROCEDURE TO SAFELY LOWER THE PLATFORM.
DO NOT ATTEMPT TO CLIMB DOWN ELEVATING ASSEMBLY.
Emergency Stop
The machine is equipped with an EMERGENCY STOP switch on both control panels.
Press the EMERGENCY STOP switch at any time to stop all machine functions.
Turn switch clockwise to reset.
Selector Switch Set To Platform
Either switch will stop all machine functions.
Both switches must be reset or machine will not operate.
Selector Switch Is Set To Base
The upper controls are locked out.
The lower controls switch must be reset or the machine will not operate.
The machine will operate from the lower controls if the upper controls switch is tripped.
Emergency Lowering
The Emergency Lowering System is used to lower the platform in case of power failure.
The Emergency Lowering switch *will* continue to function if the EMERGENCY STOP switch is
tripped.
To lower the platform, perform the following steps:
Push and hold the toggle switch down to lower the platform.
Once the platform is fully lowered, release the toggle switch.
