MANUAL
OPERATOR’S
November 2017
Part Number 0261169
Model A46JRT IS – Intrinsically Safe

The aerial platform is not electrically insulated. Death or serious injury will result from contact
with, or inadequate clearance from, an energized conductor.
Do not go closer than the minimum safe approach distance as defined by the Minimum Safe
Approach Distance section in Chapter 3–Safety.
Regard all conductors as energized.
Allow for electrical wire sag and aerial platform sway.
If the platform, booms, or any part of the aerial platform contacts a high-voltage electrical conductor,
the entire machine can become electrically charged.
If that happens, remain on the machine and do not contact any other structure or object. This includes
the ground, adjacent buildings, poles, and any other objects that are not part of the aerial platform.
Such contact could make your body a conductor to the other object, creating an electrical shock hazard
resulting in death or serious injury.
If an aerial platform is in contact with an energized conductor the platform operator must warn ground
personnel in the vicinity to stay away. Their bodies can conduct electricity creating an electrical shock
hazard resulting in death or serious injury.
Do not approach or leave the aerial platform until the electricity has been turned off.
Do not attempt to operate the lower controls when the platform, booms, or any part of the aerial plat-
form is in contact with a high-voltage electrical conductor or if there is an immediate danger of such
contact.
Personnel on or near an aerial platform must be continuously aware of electrical hazards, recognizing
that death or serious injury can result from contact with an energized conductor.

Prestart Inspection
Perform a prestart inspection before each shift as de-
scribed in Chapter 7. Do not use the aerial platform on
the job unless you are trained and authorized to do so.
Work Place Inspection and Practices
Do not use the aerial platform as a ground connection
when welding.
• The welding ground clamp must be attached to the
same structure that is being welded.
• Electrical current flow can be very intense, causing
serious internal damage to some components.
Inspect the area before and during aerial platform use.
The following are some potential hazards that may be in
the work place:
• Debris
• Slopes
• Drop-offs or holes
• Bumps and floor obstructions
• Overhead obstructions
• Unauthorized persons
• High voltage conductors
• Wind and weather conditions
• Inadequate surface and support to withstand load
forces applied by the aerial platform in all operating
configurations
Before using the aerial platform in any hazardous (clas-
sified) location, make certain it is approved and of the
type required by ANSI/NFPA 505 for use in that particular
location.
Know and understand the job site traffic-flow patterns and
obey the flagmen, road signs, and signals.
While operating the aerial platform, a good safety prac-
tice is to have qualified personnel in the immediate work
area 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
Danger
Pinch points may exist between moving components.
Death or serious injury will result from becoming
trapped between components, buildings, structures,
or other obstacles. Make sure there is sufficient clear-
ance 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.
Always look in the direction of movement.
• 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 permit
riders any place other than in the platform.
Secure all accessories, containers, tools, and other ma-
terials in the platform to prevent them from accidentally
falling or being kicked off the platform. Remove all objects
that do not belong in or on the aerial platform.
Never steady the platform by positioning it against an-
other platform.
Warning
The potential for an accident increases when operat-
ing an aerial platform that is damaged or malfunction-
ing. Death or serious injury could result from such
accidents. Do not operate the aerial platform if it is
damaged or malfunctioning.
Do not operate the aerial platform if it is damaged or not
functioning properly. Qualified maintenance personnel
must correct the problem before putting the aerial platform
back into service.
Operation
Use three points of support when entering or exiting the
platform. For example, use two hands and one foot when
climbing into the platform.
Never cover the platform floor grating or otherwise ob-
struct your view below. Make sure the area below the
platform is free of personnel before lowering.
Keep both feet positioned firmly on the platform floor.
• Operate the controls slowly and deliberately to avoid
jerky and erratic operation.
• Always stop the controls in neutral before going in
the opposite direction.
Do not dismount while the aerial platform is in motion or
jump off the platform.
Properly stow the aerial platform and secure it against
unauthorized operation at the end of each work day,
before transporting, or if it is left unattended.

Chapter 3 – Safety
A46JRT – 0261169 9
Tip-Over and Falling Hazards
Operate the aerial platform only on a firm, flat, level sur-
face capable of withstanding all load forces imposed by
the aerial platform in all operating conditions. Refer to
the General Specifications chart for the maximum wheel
load and ground pressure. Raise the booms only when
the aerial platform is on level ground.
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. Do not drive or position the aerial platform for
elevated use near any drop-off, hole, slope, soft or
uneven ground, or other tip-over hazard.
All platform occupants must wear a fall restraint device
connected to a lanyard anchor point.
It is best not to transfer from the platform to another
structure or from the structure to the platform, unless
that is the safest way to do the job. Judge each situation
separately taking the work environment into account. If
it is necessary to transfer from the platform to another
structure the following guidelines apply:
1. Where possible, place the platform over a roof or
walking structure to do the transfer.
2. Transfer your anchorage from one structure to the
other before stepping across.
3. Remember that you might be transferring to a struc-
ture where personal fall arrest is required.
4. Use the platform entrance, do not climb over or
through the guardrails.
Do not operate the aerial platform in windy or gusty condi-
tions. Do not add anything to the aerial platform that will
increase the wind loading such as billboards, banners,
flags, etc.
Never operate the aerial platform without all parts of the
guardrail system in place and the gate closed. Make
sure that all protective guards, cowlings, and doors are
securely fastened.
Do not exceed the platform capacity as indicated on the
platform rating placard on the platform. Do not carry loads
that extend beyond the platform guardrails without prior
written consent from Snorkel.
Do not operate the aerial platform from trucks, trailers, rail-
way cars, floating vessels, scaffolds, or similar equipment
unless the application is approved in writing by Snorkel.
Do not use the aerial platform as a crane, hoist, jack, or
for any purpose other than to position personnel, tools,
and materials.
Do not climb on the guardrails or use ladders, planks,
or other devices to extend or increase the work position
from the platform.
Take care to prevent rope, electrical cords, and hoses,
etc., from becoming caught in or on the aerial platform.
• If the platform or booms becomes caught on an adjacent
structure or other obstacle and is prevented from normal
motion, reverse the control to free the platform.
• If control reversal does not free the platform, evacuate
the platform before attempting to free it.
Hydraulic System
The hydraulic system contains hoses with hydraulic fluid
under pressure.
Danger
Hydraulic fluid escaping under pressure can have
enough force to inject fluid into the flesh. Serious
infection or reaction will 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.
Engine and Fuel Handling Precautions
Refer to the engine manufacturer’s Operator’s Manual for
complete information on safe engine operation, mainte-
nance, and specifications.
Danger
Engine exhaust contains carbon monoxide, a poi-
sonous gas that is invisible and odorless. Breathing
engine exhaust fumes will cause death or serious
illness. Do not run the engine in an enclosed area or
indoors without adequate ventilation.
Be careful not to run the diesel fuel tank empty. Bleed the
fuel system if air enters the lines between the tank and
the injection pump.
Allow the engine to return to idle before shutting the
engine off.
Do not smoke or permit open flames while fueling or near
fueling operations.
Never remove the fuel cap or fill the fuel tank while the
engine is running or hot. Never allow fuel to spill on hot
machine components.
Maintain control of the fuel filler nozzle when filling the
tank. Spilled fuel is a potential fire hazard.
Do not overfill the fuel tank. Allow room for expansion.

Chapter 3 – Safety
10 A46JRT – 0261169
Clean up spilled fuel immediately.
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.
Use the correct fuel grade for the operating season.
Placards and Decals
The aerial platform is equipped with placards and decals
that provide instruction for operation and accident preven-
tion. Do not operate the aerial platform if any placards or
decals are missing or not legible.

A46JRT – 0261169 11
Chapter 4 – Safety Devices
This aerial work platform is manufactured with safety de-
vices, placards, and decals to reduce the likelihood of an
accident. For the safety of all personnel, do not disable,
modify, or ignore any safety device. Safety devices are
included in the daily prestart inspection.
Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury can result from such accidents. Do not alter,
disable, or override any safety device.
If any safety devices are defective, remove the aerial plat-
form from service until qualified maintenance personnel
can make repairs.

The fluid filter gauge (refer to Figure 5.2) is located on
the filter in the engine compartment.
Figure 5.2 – Hydraulic Fluid Filter Gauge
• During high pump flow situations, the gauge indicates
the condition of the filter.
• When the needle on the gauge is in the red zone, its
time to change the filter.
Hydraulic Fluid Level Sight Gauge
A sight gauge on the end of the reservoir displays the
level of the hydraulic fluid (refer to Figure 5.3).
Figure 5.3 – Hydraulic Fluid Gauge
Remove the engine cover and check the fluid level with
the aerial platform in the stowed position, booms com-
pletely down and retracted. Otherwise, the cylinders act
as large reservoirs for hydraulic fluid making the level
appear too low. The fluid should be visible in the sight
gauge.
Chapter 5 – Gauges and Displays
The aerial platform is equipped with several gauges to
monitor the condition of the machine before and during
operation.
Fuel Gauge
The fuel gauge is located on top of the fuel tank. Access
the gauge by opening the door on the top, left rear of the
chassis (refer to Figure 5.1). Read the fuel level at the
line in the clear plastic window. The gauge indicates the
fuel tank level in fractions of a full tank.
Figure 5.1 – Fuel Tank
Note
Do not run a diesel fuel tank empty. Air in the fuel line
makes the engine hard to start.
Engine Oil
The engine oil level is measured with a dipstick. The dip-
stick is the only way to accurately determine the engine
oil level. The engine oil level should always be between
the add and full marks on the dipstick.
