■Electrical Hazard Warning
THE MHP15J AERIAL WORK PLATFORM
IS NOT ELECTRICALLY INSULATED.

tor, 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) - AS OUTLINED IN TABLE 1. AND FIGURE 3.,
ON THE NEXT PAGE.
Be sure to allow for sag and sway in the wires and the work platform.
If a MHP15J 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 MHP15J.
Suchcontact couldmake yourbody aconductor tothe otherobject creatingan electricalshock hazardre-
sulting in SERIOUS INJURY or DEATH.
DO NOT attempt to enter or leave the MHP15J until you are sure the electricity has been turned off.
If a MHP15J is in contact with a live conductor, the platform operator MUST warn others on the ground in
the vicinity of the MHP15J to STAY AWAY from the machine, since their bodies can also form a path for
electricity to ground thus creating an electrical shock hazard with possible ELECTROCUTION and
DEATH.

trained and authorized, understand the
operation characteristics of the MHP15J,
and have inspected and tested all functions
tobesuretheyareinproperworkingorder.
❑Work Place Inspection and Practices
Do not use the MHP15J as a ground for welding.
Ground to the work piece.
Before the MHP15J is used, and during use, check
theareainwhichtheMHP15Jis to beusedforpos-
sible hazards such as, but not limited to:
1. Drop-offs or holes.
2. Side slopes.
3. Bumps and floor obstructions.
4. Debris.
5. Overhead obstructions and electrical
conductors.
6. Hazardous locations.
7. Inadequate surface and support to withstand
all load forces imposed by the aerial platform
in all operating configurations.
8. Wind and weather conditions.
9. Presence of unauthorized persons.
10. Other possible unsafe conditions.
Before the MHP15J is used, determine the hazard
classification of any particular atmosphere or loca-
tion according to ANSI/NFPA 505-1987.
Any MHP15J operated in a hazardous location
must be approved and of the type required by
ANSI/NFPA 505-1987.
A recommended safety practice is to have
personnel that are trained in the operation of the
emergency controls working in the immediate area
oftheMHP15Jtoassisttheplatformoperatorinthe
event of an emergency.
When moving the platform, check the clearance
around the MHP15J to avoid contact with struc-
tures or other hazards. Always look in the direction
of motion.
Keep ground personnel from under the platform
when the platform is raised.
Secureallaccessories,containers,tools,andother
materialsin theplatform toprevent them fromacci-
dentally falling or being kicked off the platform.
DO NOT engage in any form of “horseplay” or
“stunt driving” while operating the MHP15J.
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.
When other moving equipment is in the area, take
special precautions to comply with local regula-
tions regarding warnings.
Never steady the platform by positioning it against
another platform.
DONOToperateanMHP15Jthatisnotfunctioning
properly, or has been damaged, until the machine
has been repaired by a qualified maintenance per-
son.
DO NOT operate a MHP15J that does not have all
its decals and placards attached and legible.
Watchforbystandersandneverallowanyonetobe
under, or to reach through, the machine and its
equipment while operating.
Use the recommended transport device when
loading the machine.
❑Electrocution
The MHP15J is an all metal boom,
NON-INSULATED, aerial work platform.
DONOToperateitnearELECTRICALconductors.
Regard all conductors as being energized.
DO NOT operate outside during a thunderstorm.
❑Tipover and Falling Hazards
DO NOT operate the MHP15J from a position on
trucks, trailers, railway cars, floating vessels, scaf-
folds,orsimilarequipmentunlesstheapplicationis
approved in writing by Snorkel.
If the platform or elevating assembly becomes
caught, snagged, or otherwise prevented from
normal motion by an adjacent structure or other
obstacles such that control reversal does not free
the platform, remove all personnel from the
MHP15J – 11995A page 1 - 1
CAUTION

platform before attempts are made to free the
platform using ground controls.
Under normal working conditions it is best not to
transfer from the platform to another structure or
vice versa, unless that is the safest way to do the
job. Each situation must be judged separately tak-
ing the work environment into account. The follow-
ing guidelines apply:
1. Where possible, place the work platform over
a roof or walking structure to do the transfer.
2. Transfer your anchorage from one structure
to another before you step across.
3. Remember, you might be departing the work
platform to a structure where fall arrest is
required.
4. DO NOT climb the rails. Use the entrance.
All platform occupants MUST wear and use fall re-
straint. Attach fall restraints to the platform lanyard
anchor points.
DO NOT exceedthe unrestricted platform capacity
asindicatedonthecapacityplacardattheentrance
to the platform.
ENSURE all four stabilizer foot plates are in firm
contact with the ground as laid out on page 1-1
“Work Place Inspection and Practices”. DO NOT
raisetheboomiftheMHP15Jisonsoftground.Op-
erate the boom only on a firm surface capable of
withstanding all load forces imposed by the aerial
work platform in all operating conditions.
Do Not carry loads from any point outside of the
platform.
Care shall be taken to prevent rope, electric cords,
and hoses, etc., from becoming entangled in the
aerial platform.
Raise the platform only when the MHP15J is on
level ground.
Maintain a firm footing on the platform floor.
Climbing on the guardrails is prohibited.
DO NOT use ladders, planks, or other devices to
extendorincreaseyourworkpositionfromtheplat-
form.
DONOTjerkthecontrols.Movethecontrolsslowly
and deliberately to avoid jerky and erratic opera-
tion.Alwaysstop thecontrolsin the neutral,off,po-
sition before going in the opposite direction.
DO NOT use the boom for any purpose other than
to position personnel, their tools, and materials.
DONOTusetheMHP15Jasacrane,hoist,orjack.
DO NOT operate the MHP15J in winds, or wind
gusts, of 28 mph 12.5 m/s) or more.
DO NOT add anything to the MHP15J that will in-
crease the wind loading (banners, flags, etc.).
❑Crushing
Always look in the direction of travel. Avoid over-
head obstructions.
Never cover the floor grating or otherwise obstruct
your view below.
Make sure the area below the platform is free of
personnel before lowering.
■General Safety Precautions

■Safety Device Information
Foremergencyoperationcontrolsandprocedures,
see the “Emergency Operation” chapter 9, in this
manual.
The devices listed in this chapter are safety de-
vices.
They are on the MHP15J to increase safety in the
work place for both the operator and other people
near the MHP15J.
DO NOT by pass, disable, modify, or ignore
any of these devices. Check them carefully
atthe start of eachwork shift to see thatthey
are in working order (see “Pre-operational
Inspection” chapter 7). If any is found to be
defective, remove the MHP15J from service
immediately until a qualified service
technician can make repairs.
■Emergency Stop Switches
❑At ground control box
Figure 2.1 - Emergency Stop Switch at
Ground Control Box
PresstheEMERGENCYSTOPswitchcoverdown,
at any time, under any conditions and the entire
machine stops, and nothing moves. This emer-
gency stop switch cover must be up and the switch
turned on for anything on the MHP15J to work.
❑At platform control box
Figure 2.2 - Emergency Stop Switch at
Platform Control Box
PresstheEMERGENCYSTOPswitchcoverdown,
at any time, under any conditions and the entire
machine stops, and nothing moves. This emer-
gency stop switch cover must be up and the switch
turned on for anything on the MHP15J to work.
NOTE:
The ground control box is designed to override
the platform control box. If the platform control
box EMERGENCY STOP switch is down (off) the
ground control box can still be used to start and
operate the MHP15J.
■Other Safety Devices
❑Lanyard anchor points
Figure 2.3 - Lanyard Anchor Points
MHP15J – 11995A page 2 - 1
CAUTION

Allpersonnelontheplatformshouldattachtheirfall
restraint lanyards to one of the lanyard anchor
points.
❑Gravity gate
Figure 2.4 - Gravity Gate
The gravity gate is the place in the platform guard-
rail system where you should enter and leave the
platform. Raise the gate and step under it onto the
platform. Once you have entered the platform and
attached your fall restraint 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 in-
stalled and that the gravity gate or swinging gate is
in place.
❑Foot switch
Figure 2.6 - Foot Switch
The foot switch prevents the platform from moving
if something accidentally pushes one of the plat-
form-moving controls on the platform control box.
Stepping on the foot switch is an action that must
be performed, at the same time as another action,
to make the platform move.
❑Bubble level
Figure 2.7 - Bubble Level
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.

Chapter 2. Safety Devices

❑RCD/ELCB AC outlet
Figure 2.8 - RCD/ELCB AC Outlet
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 techni-
cian.
❑Flashing light
Figure 2.9 - Flashing Light
The flashing light alerts people that the MHP15J is
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
cannotbeturnedoffwhiletheMHP15Jisrunning.
