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 qualied operator.
It is essential that the operator of the aerial work platform is not alone at
the workplace during operation.
Modications of this machine from the original design and specications
without written permission from MEC are strictly forbidden. A
modication may compromise the safety of the machine, subjecting the
platform occupants and personal around the machine to serious injury or
death.
Your MEC Aerial Work Platform has been designed, built, and tested to provide safe, dependable
service. Only authorized, trained and qualied 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.
If there is a question on application and/or operation contact:

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
boom-supported 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 specied in ANSI/SIA A92.22 & 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

Section 2 - Safety Safety

Page 3 45-J Diesel - Operator’s Manual
September 2022Section 2 - Safety Safety Alert Symbols & Fall Protection
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.
Fall Protection
ART_4713
Operators must comply with employer, job site and governmental rules
regarding the use of personal protective equipment.
If required by your employer or job site, use personal fall protection
equipment (PFPE) when operating this machine.
All PFPE must comply with applicable governmental regulations, and must be
inspected and used in accordance with the PFPE manufacturer’s instructions.
Fall restraint must be properly attached to a designated anchorage point
when driving or operating the machine. Attach only one fall restraint to each
anchorage point.

Electrocution Hazards
ELECTROCUTION HAZARD! THIS MACHINE IS NOT INSULATED!
DEATH OR SERIOUS INJURY will result from contact with or inadequate
clearance from any electrically charged conductor.
You must maintain a CLEARANCE OF AT LEAST 10 FEET (3.05 m)
between any part of the machine, or its load, and any energized 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 5507a
Art 5507c
This machine is not electrically insulated and will not provide protection from
contact with or proximity to electrical current.
Maintain safe distances from energized electrical lines and apparatus in
accordance with applicable government regulations and the following chart:
Minimum Safe Approach Distance
Voltage Minimum Safe Approach Distance
Phase to Phase Feet Meters
0 to 300 Volts Avoid Contact
Over 300V to 50kv 10 3.1
Over 50KV to 200KV 15 4.6
Over 200KV to 350KV 20 6.1
Over 350KV to 500KV 25 7.6
Over 500KV to 750KV 35 10.7
Over 750KV to 1000KV 45 13.7
Allow for platform movement, electrical line sway or sag and beware of strong
or gusty winds.
Keep away from the machine if it contacts energized electrical lines. Personnel
on the ground or in the platform must not touch or operate the machine until
energized power lines are shut o󰀨.

DO NOT exceed the maximum platform capacity. The weight of options and
accessories will reduce the rated platform capacity and must be factored into the total
platform load. Refer to the decals on the options or contact MEC.
Driving: DO NOT drive the machine on a slope that exceeds the maximum uphill or
downhill slope rating. Slope rating applies to machines in the stowed position.
Driving in stowed position: Use extreme care and reduce speed when driving
across uneven terrain, debris, unstable or slippery surfaces, and near holes or drop-
o󰀨s.
Driving with the platform elevated: DO NOT drive on or near uneven terrain,
unstable surfaces, curbs, drop-o󰀨s or other hazardous conditions.
DO NOT elevate the platform when the machine is on a surface that is soft and / or on
a slope.
STOPALL MOVEMENT if the alarm sounds and the red Tilt Indicator Light illuminates
when the platform is raised – see Tilt Indicator Light on page 23 for instructions.
Ensure that all tires are in good condition and lug nuts are properly torqued.
DO NOT push o󰀨 or pull toward any object outside the platform.
Maximum Allowable Side Force: 100 lbs (445 N).
NEVER transport tools and materials unless they are rmly secured. Secure all tools
and loose materials. DO NOT carry materials or tools on the guardrails. DO NOT
allow tools, supplies or any items to extend outside the platform.
DO NOT elevate the platform when wind speeds are in excess of 28 m.p.h. (12.5 m/
s). If wind speeds exceed 28 m.p.h. (12.5 m/s) when the platform is elevated, carefully
lower the platform and discontinue operation.
DO NOT increase the surface area of the platform (i.e. cover the rails with tarp or
plywood). Increased surface area exposed to the wind will decrease machine stability.
NEVER modify or alter the work platform without written permission from MEC.
DO NOT attach overhanging loads or use the machine as a crane. Do not allow
anything (hoses, cords, wires, ropes, etc.) to hang from the platform.
NEVER alter or disable any machine components.
DO NOT replace any part of the machine with anything except MEC-supplied or MEC-
approved parts.
NEVER use ladders or sca󰀨olds in the platform or allow them to touch any part of the
machine.
NEVER use the machine on a moving or mobile surface or vehicle
