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.

Maintenance Locks - 1930SE, 2632SE, 3346SE
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.
On machines equipped with two Maintenance Locks, both must be set to
safely work on or inspect the machine.
DO NOT engage the Maintenance Locks unless the platform in empty of
tools and material.
1930SE, 2632SE and 3346SE Machines:
On the 1930SE, the Maintenance Lock is located at the rear of the scissor stack. On the 2632SE and
3346SE, the Maintenance Lock is located at the front of the scissor stack.
Raise the platform approximately just high enough to rotate the Maintenance Lock into place.
Lift the Maintenance Lock, move it to the center of the scissor arm, then rotate it up to a vertical
position.
The Maintenance Lock must engage the scissor section above it.
DO NOT set it so that it hangs down.
Lower the platform until the Maintenance Lock rests securely on the link. Keep clear of the

There are two Maintenance Locks on these machines. Both must be set whenever work or inspection
is being performed on the machine.
The Maintenance Locks are located inside the scissor assembly.
Setting The Maintenance Locks
Raise the platform approximately 13 ft / 4 m from the ground,
just high enough to rotate the Maintenance Locks into place.
Lift the ladder-end Maintenance Lock, move it to the center of
the scissor arm, then rotate it down to a vertical position. Use
the machine entry ladder to reach the rear Maintenance Lock.
Lift the front-end Maintenance Lock, move it to the center of the
scissor arm, then rotate it up to a vertical position.
The Front End Maintenance Lock must
engage the scissor section above it.
DO NOT set it so that it hangs down.
Lower the platform until the Maintenance Locks rest lightly on
the scissor link cross tubes. Keep clear of the Maintenance
Locks when lowering the platform.

Stowing The Maintenance Locks
BOTH Maintenance Locks must be stowed
before lowering the platform
DO NOT attempt to lower the platform with
one maintenance lock in place.
Raise the platform approximately 1 ft / .3 m up so that the
Maintenance Locks clear the scissor link cross tubes.
Slide the ladder-end Maintenance Lock to the side and rotate it
stowed position. Use the machine entry ladder to reach the rear
Maintenance Lock.
Slide the front-end Maintenance Lock to the side and rotate it
stowed position.
Lower the platform.
Keep clear of the scissor linkage when lowering. If a Maintenance
Lock requires adjustment to stow it correctly, stop the lowering
function. Adjust the maintenance lock while stationary, then return to
the lowering function.

Hydraulic System, Electrical System 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.
