Electrical Hazard Warning
DANGER
THE SNORKELIFT AERIAL WORK PLATFORM
IS NOT ELECTRICALLY INSULATED.
If the platform, booms, or any other conductive part of a Snorkelift 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) - 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 Snorkelift 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 Snorkelift.
Such contact could make your body a conductor to the other object creating an electrical shock hazard
resulting in SERIOUS INJURY or DEATH.
DO NOT attempt to enter or leave the Snorkelift until you are sure the electricity has been turned off.
If a Snorkelift is in contact with a live conductor, the platform operator MUST warn others on the ground
in the vicinity of the Snorkelift 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.
DO NOT attempt to operate the Snorkelift ground controls when the platform, booms, or any other
conducting part of a Snorkelift is in contact with electrical wires or if there is an immediate danger of
such contact.
Regard all conductors as energized.
Personnel working on or near a Snorkelift must be continuously aware of electrical hazards,
recognizing that SERIOUS INJURY or DEATH can result if contact with an electrical wire does occur.

5. Overhead obstructions and high voltage
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 AB46J is used, determine the hazard
classification of any particular atmosphere or
location according to ANSI/NFPA 505-1987.
Any AB46J operated in a hazardous location
must be approved and of the type required by
ANSI/NFPA 505-1987.
DO NOT engage in any form of “horseplay” or
“stunt driving” while operating the AB46J.
DO NOT permit riders on the machine anyplace
other than on the platform.
When other moving equipment is in the area,
take special precautions to comply to local
regulations regarding warnings.
Never steady the platform by positioning it
against another platform.
DO NOT operate an AB46J that is not functioning
properly, or has been damaged, until the machine
has been repaired by a qualified maintenance
person.
DO NOT operate an AB46J that does not have all
its Decals and Placards attached and legible.
Drive the machine with care and at speeds
compatible with conditions. Use extra caution
when driving over rough ground, on slopes, and
when turning.
Know and understand the job site traffic flow
patterns and obey the flagmen, road signs, and
signals.
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.
A recommended safety practice is to have
personnel that are trained in the operation of the
emergency controls working in the immediate
area of the AB46J to assist the platform operator
in the event of an emergency.
AB46J – 0163187 page 1 - 1
1. Safety
Electrocution
❑
The AB46J is an all metal boom, NONINSULATED, aerial work platform. DO NOT
operate it near ELECTRICAL conductors. Regard
all conductors as being energized.
DO NOT operate outside during a thunderstorm.
Tipover and Falling Hazards
❑
DO NOT operate an AB46J from a position on
trucks, trailers, railway cars, floating vessels,
scaffolds, or similar equipment unless the
application is 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
platform before attempts are made to free the
platform using ground controls.
The guardrail system is your primary fall
protection. Never operate without all parts of the
guardrail system in place and the gate closed.
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
taking the work environment into account. The
following 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.
Maintain a firm footing on the platform floor.
Climbing on the guardrails is prohibited.
DO NOT use ladders, planks, or other devices to
extend or increase your work position from the
platform.
All platform occupants MUST use fall restraint.
Attach fall restraints to the platform anchorage
points.
DO NOT exceed the unrestricted platform
capacity as indicated on the capacity placard on
the platform.
DO NOT raise the boom if the AB46J is on soft
ground. Operate the boom only on a firm surface
capable of withstanding all load forces imposed
by the aerial platform in all operating conditions.
Raise the platform only when the AB46J is on
level ground.
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.
DO NOT jerk the controls. Move the controls
slowly and deliberately to avoid jerky and erratic
operation. Always stop the controls in the neutral,
off, position before going in the opposite direction.
DO NOT use the boom for any purpose other than
to position personnel, their tools, and materials.
DO NOT use the AB46J as a crane, hoist, or jack.
DO NOT operate the AB46J in winds, or wind
gusts, of 28 mph (45 km/h) or more.
DO NOT add anything to the AB46J that will
increase the wind loading ( banners, flags, etc.).
Crushing
❑
Always look in the direction of travel. Avoid
overhead 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
❑
Personnel Precautions
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 and seek
assistance from management.

Make sure that all protective guards, cowlings,
and doors are in place and secure.
Be sure the guardrail system, including the gate,
is in place and secure.
❑
Mounting and Dismounting Precautions
Use three points of support when getting on or off
the platform (e.g., two hands and one foot).
Keep the platform clean.
DO NOT jump off the machine.
DO NOT dismount while the machine is in motion.
page 1 - 2 AB46J – 0163187
Starting and Stopping Precautions
❑
DO NOT start until all personnel are clearly away
from the machine.
Before leaving the operator’s station, place the
machine in the stowed position.
When leaving the machine parked or unattended,
remove the starter key from the Master Switch,
set the Battery switch to OFF, then lock the
Battery switch.
Operating Precautions
❑
DO NOT modify the AB46J 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
AB46J.
Limit travel speeds according to conditions. Take
into account: grade, surface, congestion, visibility,
side slope, location of personnel, and other
hazards.
Operator Maintenance Precautions
❑
Charge batteries in a well-ventilated area free of
flame, sparks, or other hazards that might cause
fire or explosion.
1. Safety
■
Safety Decals and Placards
There are several safety decals and placards on
the AB46J. Their locations and descriptions are
shown in this section. Take time to study them.
CAUTION
Be sure that all the safety decals and placards
on the AB46J are legible. Clean or replace
them if you cannot read the words or see the
pictures. Clean with soap & water and a soft
cloth. DO NOT use solvents.
You must replace a decal or placard if it is
damaged, missing, or cannot be read. If it is
on a part that is replaced, make sure a new
decal or placard is installed on the replaced
part. See your Snorkel dealer for new decals
and placards.
Refer to Placards and Decals Inspection Chart
and drawing in the “Daily Inspection and
Maintenance” chapter 7, for part numbers,
location, and required quantities of all placards
and decals.
Lead-acid batteries contain sulfuric acid. Sulfuric
acid will damage your eyes or skin on contact.
When you work around lead-acid batteries, wear
a face shield to avoid getting acid in your eyes.
Wear rubber gloves and protective clothing to
keep acid off your skin. 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.
CAUTION
DO NOT use your hand to search for hydraulic
oil leaks. High pressure hydraulic oil can easily
cut and penetrate your skin-averyserious
injury that requires immediate attention by a
medical specialist trained in that type of injury.
Use a piece of cardboard or wood to search
for hydraulic oil leaks.
DO NOT attempt repairs unless you are
trained. Refer to manuals and experienced
repair personnel for help.

2. Safety Devices
■
Safety device information
For emergency operation controls and
procedures, see the “Emergency Operation”
chapter 9, in this manual.
The devices listed in this chapter are safety
devices. They are on an AB46J to increase safety
in the work place for both the operator and other
people near an AB46J. DO NOT by-pass, disable,
modify, or ignore any of these devices. Check
them carefully at the start of each work shift to
see that they are in working order (see “Daily
Inspection and Maintenance” chapter 7).
If any is found to be defective, immediately
remove the AB46J from service until a qualified
service technician can make repairs.
Emergency Power Battery
❑
Emergency stop switches
❑
At the ground control box: Press the large red
Emergency Stop button in, at any time, under
any conditions, and the entire machine stops, the
drive motors and pump turn off, the brakes
automatically set, and nothing moves. This switch
must be pulled out (on) for anything to work.
The emergency power battery powers the
emergency operating circuits. If the platform is
aloft when regular power fails, emergency battery
power is the only way to lower the platform, there
is no manual bleed down procedure.
Thus, maintenance of the emergency power
battery is very important. The emergency power
battery should always be kept at full charge and
the battery terminals kept free of corrosion.
AB46J – 0163187 page 2 - 1
At the platform control box: Press the large red
Emergency Stop button down (off) and the
entire machine stops, the drive motors and pump
turn off, the brakes automatically set, and nothing
moves. This switch must be pulled to its up (on)
position to control the AB46J from the platform.
The ground control box will override the
platform control box. If the platform control box
Emergency Stop button is down (off) the
ground control box can still be used to start
and operate the AB46J.
2. Safety Devices
Flashing Lights
❑
GFCI (Ground Fault Circuit Interrupt)
❑
The optional flashing lights alert people that the
AB46J is present. The lights flash at about one
flash per second any time the Battery switch,
Master Key Switch, and the Emergency Stop
switch (at the ground) are all ON. There is no
ON/OFF switch for the flashing lights.
Platform Foot Switch
❑
The platform foot switch prevents the platform
from moving if something accidentally pushes
one of the platform 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.)
The (GFCI) ground fault circuit interrupt is located
near the platform control box. To use the outlets,
connect the power input connector, on the top
rear of the chassis, to a source of 125 volt AC,
15 A electrical power.
The GFCI protects against electricity flowing to
ground. When electricity flows to ground the
GFCI shuts off power to the electrical outlets.
To reset the outlets:
1. Unplug the equipment being used.
2. Press the RESET button on the GFCI.
This should restore power to the outlets. If it does
not, unplug the source of power and refer the
problem to a trained service technician.
❑
Platform Gravity Gate
DANGER
Serious Injury can result from sudden stops.
To avoid sudden stops, Do Not remove your
foot from the foot switch while the AB46J is in
motion.
page 2 - 2 AB46J – 0163187
The platform gravity gate is the place in the
platform guardrail 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.
Ground Operation Switch
❑
The Ground Operation switch prevents the
platform from moving if something accidentally
pushes one of the platform moving switches at
the ground control box.
2. Safety Devices
Operator Horn
❑
The operator horn is used primarily to get the
attention of people on the ground when you are
working aloft.
For the horn to work the Battery switch must be
ON and the following switches, on the ground
control box, must be set as indicated:
Platform/Ground Selector . . . . . . PLATFORM
Emergency Stop . . . . . . . . . . . . . . . Pulled Out
Master Key Switch . . . . . . . . . . . . . . . . . . . ON
Pushing the Ground Operation switch is an
action that MUST be performed, at the same time
as another action, to make the platform move.
❑
Platform Guardrails
The platform guardrails help protect you from
falling off the platform. Be sure the guardrails are
properly installed and that the gate is in place.
Lanyard Anchor Points
❑
All personnel on the platform should attach their
fall restraint lanyards to one of the lanyard anchor
points.
AB46J – 0163187 page 2 - 3
2. Safety Devices
Level Sensor
❑
The level sensor detects how far out of level the
turntable is. If the turntable gets over 5° out of
level the level sensor activates the tilt alarm
(described in this chapter).
Motion Warning Alarm
❑
The optional motion warning alarm emits a loud
beeping sound, at ground level, anytime the
Drive/Steer controller is in FORWARD or
REVERSE or anytime the booms move. This
alarm alerts people on the ground that the AB46J
is traveling along the ground.
❑
Platform Swinging Gate
Tilt Alarm
❑
The tilt alarm warns the AB46J operator that the
AB46J is over 5° out of level.
If the tilt continues to increase, the AB46J will
eventually tip over.
CAUTION
When you hear the loud two toned alarm,
(high-low-high-low...), immediately retract and
lower the platform. When the platform is
completely down, determine and correct the
cause of the tilt before raising the platform
again.
The optional platform swinging gate is designed
to automatically close after you enter or leave the
platform.
It helps prevent people from falling off the
platform.
