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.

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
as indicated on the capacity placard at the

entrance to the platform. Do not carry loads from
any point outside of the platform.
Make sure that all protective guards, cowlings, and
doors are in place and secure. Be sure the guard-
rail system, including the gate, is in place and se-
cure.
Do not climb on the guardrails or use ladders,
planks, or other devices to extend or increase your
work position from the platform.
Do not use the MHP as a crane, hoist, or jack,or for
any other purpose other than to position personnel,
their tools, and materials.
Do not operate the MHP14AT / MHP13AT in winds,
or wind gusts, of 28 mph, 45kph 12.5 m/s) or more.
Do not add banners, flags, screens or
shelters etc., to areas of the MHP that are
exposed to wind forces as this will increase
the wind loading and effect stability.
■General Safety Precautions
Do not modify the MHP14AT / MHP13AT in any
way.
When parts or components are replaced, they shall
be identical or equivalent to original Snorkel parts
or components.
Do not override any of the safety features of the
MHP14AT / MHP13AT.
■Hydraulic System Precautions
The hydraulic system contains hoses with hydrau-
lic fluid under pressure.
Hydraulic fluid escaping under pressure can
have enough force to inject fluid into the
flesh. Serious infection or reaction can
result if medical treatment is not given
immediately. In case of injury by escaping
hydraulic fluid, seek medical attention at
once.
DO NOT place your hand or any part of your body in
front of escaping hydraulic fluid. Use a piece of
cardboard or wood to search for hydraulic leaks.
Do not attempt repairs to hydraulic systems unless
you are trained. Refer to experienced repair per-
sonnel for help.
■Fire Prevention
Never operate your MHP near a flame or spark. Hy-
draulic oil and gasoline are flammable and can ex-
plode.
NOTE:
This machine is equipped with an internal
combustion engine (in it's standard configuration)
and should not be used on or near any
unimproved forest-covered, brush-covered or
grass covered land unless the engine's exhaust
system is equipped with a spark arrester meeting
applicable laws. If a spark arrester is used, it
should be maintained in effective working order
by the operator.
■Engine and Fuel Handling Precautions
Engine exhaust contains carbon monoxide,
a poisonous gas that is invisible and
odourless. Breathing engine exhaust fumes
can cause death or serious illness. Do not
run the engine in an enclosed area or
indoors without adequate ventilation.
Only refuel your MHP outdoors in a clear area void
of gas fumes or spilled gas.
Never remove the fuel cap or refuel a gasoline en-
gine while the engine is running or hot. ALWAYS al-
low the engine to cool before refueling. Never allow
fuel to spill on hot machine components.
DO NOT smoke or permit open flames while
fueling or near fueling operations.
Maintain control of the fuel filler nozzle when filling
the tank.
ENSURE you use an approved fuel container
with appropriate fuel filler nozzle (see
picture below)
MHP14AT & MHP13AT – 13618-1 Rev B page 1- 3

DANGER
WARNING
DANGER
CAUTION

Do not fill the fuel tank to capacity. Allow room for
expansion.
If gasoline is spilled, clean up spilled fuel
immediately, push/tow the MHP away from the
area of the spill and avoid creating any source of
ignition until the spilled fuel has evaporated.
Tighten the fuel tank cap securely. If the fuel cap is
lost, replace it with an approved cap from Snorkel.
Use of a non-approved cap without proper venting
may result in pressurization of the tank.
Never use fuel for cleaning purposes.
For diesel engines, use the correct fuel grade for
the operating season.
■Batteries
Charge batteries in a well ventilated area free of
flame, sparks, or other hazards that might cause
fire or explosion.
Batteries give off hydrogen and oxygen that
can combine explosively. Death or serious
injury can result from a chemical explosion.
Do not smoke or permit open flames or
sparks when checking batteries.
Battery acid can damage the skin and eyes.
Serious infection or reaction can result if
medical treatment is not given immediately.
Wear face and eye protection, rubber gloves
and protective clothing when working near
batteries.
If acid contacts your eyes, flush immediately
with clear water and get medical attention. If
acid contacts your skin, wash off
immediately with clear water.
■Height Restriction
The height restrictor fitted to the standard
MHP13AT, is not the same device as the
10.9m restriction kit, although both of these
devices achieve the same result of
restricting the maximum height of the
platform to 10.9m from the ground.
This is to allow the unit to be operated by
unlicensed operators in accordance with Austra-
lian legislation.
An Australian operator MUST hold a WP
Certificate of Competency in order to
operate the machine at heights in excess of
11m.
■Height Restriction on MHP13AT
The MHP13AT (in standard mode) is fitted with a
restrictor in the upper hydraulic lift cylinder to keep
the platform to a maximum height of 10.9m.
■10.9 Metre Restriction Kit
Machines that are built for the Australian market
may be fitted with a 10.9m restriction kit.
This kit which can be fitted to the MHP14AT is fitted

❑Gravity gates
Figure 2.4 - Gravity Gates
The gravity gates are the places in the platform
guardrail system where you should enter and leave
the platform. Raise the gate where you wish to en-
ter and step under it onto the platform. Once you
have entered the platform and attached your safety
harness lanyard to an anchor point, check to see
that the gravity gate has fallen back into place.
❑Guardrails
Figure 2.5 - Guardrails
The guardrails help protect you from falling off the
platform. Be sure the guardrails are properly
installed and that the gravity gate or swinging gate
is in place.
❑Height restriction on MHP13AT
The MHP13AT (in standard mode) is fitted with a
restrictor in the upper hydraulic lift cylinder to keep
the platform to a maximum height of 10.9m.
❑10.9m height restriction kit (Option)
This kit may be fitted to machines manufactured for
the Australian market.
It is fitted to restrict the maximum height to the
platform floor to 10.9m from the ground. This is to
allow the unit to be operated by unlicensed
operators in accordance with Australian
legislation.
Note - Height Restriction Kit
See the Options chapter page 6for details
concerning this kit.
❑Enable switch
The enable switch must be operated in conjunction
with the boom/platform moving function you select.
The purpose of this switch is to prevent the platform
from moving if something or someone accidentally
pushes one of the boom/platform moving controls.
There are enable switches fitted to both the Upper
and Lower Control Boxes.

❑Enable switch (foot) - Optional
Figure 2.8 - Enable Switch (Foot)
The foot switch performs the same function as the
standard enable switch described above. Stepping
on the foot switch is an action that must be
performed, at the same time as another action, to
make the booms/platform move.
Note:
If you have the optional 'foot switch' fitted the
Enable switches on the Upper Control Box and
the Ground Control Box will still function.
■Platform Overload Protection
As soon as either boom is raised out of the travel
cradle (a boom stowed switch changes state) the
overload protection system becomes active.
●If 90% of rated capacity is reached in the
platform the overload light will illuminate.
This is a warning to the operator that the platform
is reaching rated capacity.
Normal function will remain and the machine can
continue to be used
●If 100% of rated capacity is reached in the
platform the overload light will continue to
be illuminated and an alarm will sound.
This is a warning to the operator that rated capac-
ity has been reached and the platform load must be
reduced.
Normal function will remain to allow the platform to
be positioned to remove some load from the plat-
form.
Note:
The machine should not be operated
continuously with the overload alarm sounding.
●If 110% of rated capacity is reached in the
platform the overload light will continue to
be illuminated and an alarm will continue
to sound and all functions will be disabled.
The operator must remove load from the platform.
Normal function will resume once the platform load
has been reduced below 110% continuously for at
least two (2) seconds.

A bubble level is located on the trailer side rail, be-
side the outrigger controls. Watch the bubble level
while you set the stabilisers. Lower the stabilisers,
one at a time, just enough to center the bubble in
the circle on top of the guage. When the bubble is
centered the platform is level and can be safely
raised.
❑RCD/ELCB AC outlet (Option)
Figure 2.12 - RCD/ELCB AC Outlet, Vertical
Mounting
The RCD (Residual Current Device) is located at
the base and will protect against short circuits to
earth. When there is a short circuit the RCD will
shut down the 230v AC power to the platform out-
let.
To reset the outlet disconnect the power tool lead
from the platform box and reset the RCD at the
base. If the problem persists call a trained service
technician.
■Stabiliser/Boom Interlock Test
All machines in the Snorkel ‘MHP’ Series of Trailer
Mounted Elevating Work Platforms are fitted with a
very important safety feature, a ‘Stabiliser/Boom
Interlock’ system that prevents the booms being el-
evated to an unsafe position unless all four stabilis-
ers have been correctly set and have made firm
contact with the ground.
This same safety feature also prevents the Stabilis-
ers being operated while either or both Booms are
elevated.
The correct operation of the Stabiliser/Boom
Interlock is critical to ensure that the MHP is
operated safely and without risk.
Detailed instructions on how to carry out a test to
ensure that this function is working correctly are
provided at the beginning of the Pre-Operational
Inspection chapter in this manual.
❑Flashing light (Option)
The flashing light alerts people that the booms /
platform of the MHP14AT / MHP13AT are moving.
The light flashes at about one flash per second any
time the MASTER KEY switch is on. There is no
ON/OFF switch for the flashing light, it cannot be
turned off while the MHP14AT / MHP13AT is
running.
