Electrical Hazard
■Electrical Hazard Warning
THE MHP14AT / MHP13AT AERIAL WORK PLATFORM, IN STANDARD
CONFIGURATION, IS NOT ELECTRICALLY INSULATED.
If the platform, booms, or any other conductive part of a MHP14AT / MHP13AT contacts a high-voltage
electrical conductor, the result can be SERIOUS INJURY or DEATH for persons on or near the machine.
GO NO CLOSER THAN THE MINIMUM SAFE APPROACH DISTANCES
(M.S.A.D) - SEE BELOW.
Be sure to allow for sag and sway in the wires and the work platform.
If a MHP14AT / MHP13AT comes in contact with a live electrical conductor, the entire machine can be
charged.
If that happens, you should remain on the machine and not contact any other structure or object within
reach. That includes the ground, adjacent buildings, poles, and any object not a part of the MHP14AT /
MHP13AT.
Such contact could make your body a conductor to the other object creating an electrical shock hazard re-
sulting in SERIOUS INJURY or DEATH.
DO NOT attempt to enter or leave the MHP14AT / MHP13AT until you are sure the electricity has been
turned off.
If a MHP14AT / MHP13AT is in contact with a live conductor, the platform operator MUST warn others on
the ground in the vicinity of the MHP14AT / MHP13AT to STAY AWAY from the machine, since their bod-
ies can also form a path for electricity to ground thus creating an electrical shock hazard with possible
ELECTROCUTION and DEATH.
DO NOT attempt to operate the MHP14AT / MHP13AT ground controls when the platform, booms, or any
other conducting part of a MHP14AT / MHP13AT is in contact with electrical wires or if there is an immedi-
ate danger of such contact.
Regard all conductors as energised.
Personnel working on or near a MHP14AT / MHP13AT must be continuously aware of electrical hazards,
recognizing that SERIOUS INJURY or DEATH can result if contact with an electrical wire does occur.
It is the OPERATOR'S responsibility to ensure M.S.A.D., (subject to local regulations and laws),
are known and adhered to.

1. Safety
■Safe Operation
Knowledge of the information in this manual, and
proper training, provide a basis for safely operating
the MHP14AT / MHP13AT. Know the location of all
the controls and how they operate to act quickly
and responsibly in an emergency.
Safety devices reduce the likelihood of an acci-
dent. Never disable, modify, or ignore any safety
device. Safety alerts in this manual indicate situa-
tions where accidents may occur.
If any malfunction, hazard or potentially unsafe
condition relating to capacity, intended use, or safe
operation is suspected, stop the operation of the
MHP and seek assistance.
The operator bears ultimate responsibility for
following all manufacturers instructions and
warnings, regulations and safety rules of their
employer and/or any country or regional law.
■Electrocution Hazards
The MHP14AT / MHP13AT is an all metal boom ae-
rial work platform and is not electrically insu-
lated.
Do not operate it near electrical conductors.
Regard all conductors as being energised.
Do not operate outside during a thunderstorm.
■Pre-start Inspection
At the start of each work shift, the MHP14AT /
MHP13AT shall be given a visual inspection and
function test. See the “Pre-operational Inspection
and Maintenance” chapter 7, in this manual for a
list of items to inspect and test.
DO NOT operate the MHP14AT / MHP13AT
unless you are trained and authorised,
understand the operation characteristics of
the MHP14AT / MHP13AT, and have
inspected and tested all functions to be sure
they are in proper working order.
NEVER use an MHP14AT / MHP13AT that has
a known fault or is malfunctioning in any way
until the machine has been repaired by a
qualified technician.
Operating a machine in faulty condition
could result in death or serious injury.
NOTE:
Whilst some of the safety rules and guidelines
that follow may not apply specifically to this
machine (e.g. references to driving) they are
included as part of an overall safety strategy
relating to the use of elevating work platforms.
■Work Place Inspection and Practices
Do not use the MHP14AT / MHP13AT as a ground
for welding. Ground to the work piece.
Before the MHP14AT / MHP13AT is used, and dur-
ing use, check the area in which the MHP14AT /
MHP13AT is to be used for possible hazards such
as, but not limited to:
●Drop-offs or holes.
●Side slopes.
●Bumps and floor obstructions.
●Debris.
●Overhead obstructions and electrical
conductors.
●Hazardous locations.
●Inadequate surface and support to withstand
all load forces imposed by the aerial platform
in all operating configurations.
●Wind and weather conditions.
●Presence of unauthorised persons.
●Other possible unsafe conditions.
Before the MHP14AT / MHP13AT is used, deter-
mine the hazard classification of any particular at-
mosphere or location according to ANSI/NFPA 505.
Any MHP14AT / MHP13AT operated in a hazard-
ous location must be approved and of the type re-
quired by ANSI/NFPA 505.
While operating the MHP a recommended safety
practice is to have trained and qualified personnel
in the immediate work area of the MHP14AT /
MHP13AT to:
●Help in case of an emergency.
●Operate emergency controls as required.
●Watch for loss of control by platform
operator.
●Warn the operator of any obstructions or
hazards that may not be obvious to them.
●Watch for soft terrain, sloping surfaces,
drop-offs, etc., where stability could be
jeopardized.
●Watch for bystanders and never allow
anyone to be under, or to reach through the
booms while operating the aerial platform.
MHP14AT & MHP13AT – 13618-1 Rev B page 1- 1
WARNING
DANGER

Pinch points may exist between moving
components. Death or serious injury can
result from becoming trapped between
components, buildings, structures, or other
obstacles. Make sure there is sufficient
clearance around the machine before
moving the chassis, booms, or platform.
Allow sufficient room and time to stop
movement to avoid contact with structures
or other hazards.
Keep ground personnel from under the platform
when the platform is raised.
Secure all accessories, containers, tools, and
other materials in the platform to prevent them from
accidentally falling or being kicked off the platform.
Always look in the direction of travel. Drive with
care and at speeds compatible with the work-place
conditions. Use caution when driving over rough
ground, on slopes, and when turning.
Do not engage in any form of “horseplay” or “stunt
driving” while operating the MHP14AT / MHP13AT.
Do not permit riders on the machine anyplace other
than on the platform.
Remove all loose objects stored in or on the ma-
chine, particularly in the platform. Remove all ob-
jects which do not belong in or on the machine.
Never steady the platform by positioning it against
another platform.
Do not operate an MHP14AT / MHP13AT that is
damaged or not functioning properly. Do not use
the MHP until the machine has been repaired by a
qualified maintenance person.
Do not operate a MHP14AT / MHP13AT that does
not have all its decals and placards attached and
legible.
Watch for bystanders and never allow anyone to be
under, or to reach through, the machine and its
equipment while operating.
Use the recommended transport device when
loading the machine.
■Operation
If you encounter any suspected malfunction of the
aerial platform, or any hazard or potentially unsafe
condition relating to capacity, intended use, or safe
operation, cease operation immediately and seek
assistance from management.
Use three points of support when getting on or off
the platform (two hands and one foot or a similar set
of points). Keep the platform clean.
Maintain a firm footing on the platform floor. Oper-
ate the controls slowly and deliberately to avoid
jerky and erratic operation. Always stop the con-
trols in neutral before going in the opposite direc-
tion.
Do not dismount while the platform is in motion or
jump off the machine.
Do not start until all personnel are clearly away
from the machine.
Never cover the floor grating or otherwise obstruct
your view below. Make sure the area below the
platform is free of personnel before lowering.
■Tipover and Falling Hazards
Operate the MHP only on a firm, flat, level surface
capable of withstanding all load forces imposed by
the MHP14AT / MHP13AT in all operating
conditions.
The MHP can tip over if it becomes unstable.
Death or serious injury can result from a
tip-over accident. Do not drive or position
the MHP platform for elevated use near any
drop-ff, hole, slope, soft or uneven ground,
or other tip-over hazard.
Do not operate the MHP14AT / MHP13AT from a
position on trucks, trailers, railway cars, floating
vessels, scaffolds, or similar equipment unless the
application is approved in writing by Snorkel.
Care shall be taken to prevent rope, electric cords,
and hoses, etc., from becoming entangled in the
aerial platform. If the platform or elevating
assembly becomes caught, snagged, or otherwise
prevented from normal motion by an adjacent
structure or other obstacle such that control
reversal does not free the platform, remove all
personnel from the platform before attempts are
made to free the platform using ground controls.
No person shall access or egress from the platform
in the elevated position (except in an emergency)
unless the requirements of AS2550.10 have been
met.
For full requirements refer directly to AS2550.10.
All platform occupants MUST wear and use safety
harness. Attach safety harnesss to the platform
lanyard anchor points.
Do not exceed the unrestricted platform capacity
