Introduction
This Operator’s Manual has been designed to provide you, the owner, user or operator, with the
instructions and operating procedures essential to properly and safely operate your MEC Aerial Work
Platform for positioning personnel, along with their necessary tools and materials, to overhead work
locations.
This Operator's Manual and other manuals provided by MEC on the
machine must be read and understood prior to operating your MEC Aerial
Work Platform. The operator should not accept operating responsibility
until he/she has read and understands the operator’s manual as well as
having operated the MEC Aerial Work Platform under supervision of an
authorized, trained and qualified operator.
It is essential that the operator of the aerial work platform is not alone at
the workplace during operation.
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 the
platform occupants and personal around the machine to serious injury or
death.
Your MECAerial Work Platform has been designed, built, and tested to provide safe, dependable
service. Only authorized, trained and qualified personnel shall 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 owner, user and operator.

Safety
DO NOT operate this machine until you have read and understood this manual, have
performed the Workplace Inspection, Pre-Start Inspection and Routine Maintenance, and have
completed all the test operations detailed in the Operating Instructions section.
Failure to read, understand and follow all safety rules, warnings, and instructions could result in
serious injury or death. For your safety and the safety of those around you, you must operate your
machine as instructed in this manual.
MEC designs aerial work platforms to safely and reliably position personnel, along with their
necessary tools and materials, at overhead work locations. The owner/user/operator of the machine
should not accept responsibility for the operation of the machine unless properly trained.
ANSI and other applicable standards identify requirements of all parties who may be involved with
self-propelled elevating work platforms. The Manual of Responsibilities is considered a part of this
machine and can be found in the manual compartment, located at the platform control station. To
ensure safe use of machine, inspections and training specified in ANSI/SIAA92.22 & A92.24 must be
performed at designated intervals as prescribed.
This product can expose you to chemicals known to the State of California
to cause cancer and birth defects or other reproductive harm. For more

between any part of the machine, or its load, and any electrical line or
apparatus carrying over 300 Volts up to 50,000 Volts. One foot (30.5 cm)
additional clearance is required for every additional 30,000 Volts.
Observe Minimum Safe Approach Distance.
ART_3061
ART_3060
DO NOT work in close proximity to, or in contact with, energized power lines
and electrical equipment. This machine is not insulated and WILL NOT protect
the operator from injury or the machine from damage.
Refer to Table and all applicable governmental regulations for the minimum
safe distances from energized power lines and electrical equipment.
