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.

Safe Operation
The following safety information is vitally
important for safe operation of the AB50J. Failure
to follow these instructions can result in personal
injury or DEATH.
Pre-Start Inspection
❑
At the start of each work shift, the AB50J shall be
given a visual inspection and function test. See
the “Daily Inspection and Maintenance” chapter
7, in this manual for a list of items to inspect and
test.
1. Safety
When moving the platform, check the clearance
around the AB50J to avoid contact with
structures or other hazards. Always look in the
direction of motion.
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.
DO NOT engage in any form of “horseplay” or
“stunt driving” while operating the AB50J.
CAUTION
DO NOT operate the AB50J unless you are
trained and authorized, understand the
operation characteristics of the AB50J, and
have inspected and tested all functions to be
sure they are in proper working order.
Work Place Inspection and Practices
❑
Do not use the AB50J as a ground for welding.
Ground to the work piece.
Before the AB50J is used, and during use, check
the area in which the AB50J is to be used for
possible 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 using the aerial platform in any hazardous
(classified) location, make certain it is approved
and of the type required by ANSI/NFP A 505 for
use in that particular location.
DO NOT permit riders on the machine anyplace
other than on the platform.
Remove all loose objects stored in or on the
machine, particularly in the platform. Remove all
objects which do not belong in or on the machine.
When other moving equipment is in the area,
take special precautions to comply with local
regulations regarding warnings.
Never steady the platform by positioning it
against another platform.
DO NOT operate an AB50J that is not functioning
properly, or has been damaged, until the machine
has been repaired by a qualified maintenance
person.
DO NOT operate an AB50J 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 AB50J to assist the platform operator
in the event of an emergency.
AB50J – 0163189 page 1 - 1
1. Safety
Electrocution
❑
The AB50J is an all metal boom,
NON-INSULATED, 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 the AB50J 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.
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 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
arrest
4. Use the platform entrance, do not climb over
the guard rails.
All platform occupants MUST wear a fall restraint
device connected to a lanyard anchor point.
DO NOT exceed the unrestricted platform
capacity as indicated on the capacity placard at
the entrance to the platform.
DO NOT raise the boom if the AB50J 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.
Do Not carry loads that extend beyond the
platform guardrails without prior written consent
from Snorkel.
is required.
personal fall
Raise the platform only when the AB50J 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
extend or increase your work position from the
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 AB50J as a crane, hoist, or
jack.
DO NOT operate the AB50J in winds, or wind
gusts, of 28 mph (45 km/h) or more.
DO NOT add anything to the AB50J 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.
❑
Operator General Precautions
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.
Care shall be taken to prevent rope, electrical
cords, and hoses, etc., from becoming entangled
in the aerial platform.
page 1 - 2 AB50J – 0163189
1. Safety
Mounting and Dismounting Precautions
❑
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.
DO NOT jump off the machine.
DO NOT dismount while the machine is in
motion.
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 par ked or unattended,
remove the starter key from the Master Key
Switch, set the Battery switch to OFF, then lock
the Battery switch.
Operating Precautions
❑
DO NOT modify the AB50J 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
AB50J.
Limit travel speeds according to conditions. Take
into account: grade, surface, congestion, visibility,
side slope, location of personnel, and other
hazards.
❑
Operator Maintenance Precautions
Use extreme caution when removing radiator
caps.Park the machine and let it cool down
before opening a pressurized compartment.
CAUTION
DO NOT use your hand to search for hydraulic
oil leaks.High pressure hydraulic oil can easily
cut and penetrate your skin — a very serious
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.
Fuel Handling Precautions
❑
DO NOT smoke or permit open flames while
fueling or near fueling operations.
Never remove the fuel cap or refuel a gasoline
engine 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.
DO NOT fill the fuel tank to capacity. Allow room
for expansion.
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.
For diesel engines, use the correct fuel grade for
the operating season.
■
Safety Placards and Decals
There are several safety placards and decals on
the AB50J.Their locations and descriptions are
shown in this section. Take time to study them.
CAUTION
Be sure that all the safety placards and decals
on the AB50J 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 placard or decal 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 in the “Daily
Inspection and Maintenance” chapter 7, for
part numbers, location, and required quantities
of all placards and decals.

Safety Device Information
For emergency operation controls and procedures,
see the “Emergency Operation” chapter 9.
The devices listed in this chapter are safety
devices.
They are on the AB50J to increase safety in the
work place for both the operator and other people
near the AB50J.
CAUTION
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, remove the AB50J from service
immediately until a qualified service technician
can make repairs.
■
Alarms
2. Safety Devices
the other is located on the platform control box.
The buzzers are connected in parallel, they both
emit the same pattern of sound at the same time.
The tilt alarm is also located on the platform
control box.
The different alarm sound patterns these three
devices make are shown in the table immediately
below and discussed below the table.
There are two buzzers on the AB50J.One is
located on the ground control box,
Engine start-up
Overheating
Low oil pressure
Alternator not charging
Axle unlocked
Tilt alarm
Optional alarms:
All motion
Descending boom

❑
Start-Up Alarm
When the Master Key Switch or Anti-Restart
switch is turned ON, just prior to starting, the
buzzers emit a loud continuous tone to alert
others in the area that the AB50J is about to
start. The tone will continue until the AB50J starts
or the switch is turned OFF.

5 sec.
AB50J – 0163189 page 2 - 1
2. Safety Devices
Engine Shut-Off Alarm
❑
The engine shut-off alarm comes on when the
engine is overheating or the oil pressure is low.
When the alarm sounds you should immediately
lower the platform completely down then turn the
engine off until the condition that caused the
alarm has been corrected. See “Automatic
Shut-Offs and Circuit Breakers” chapter 5 for
more information.
If the engine has automatically shut off, and
will not restart, go to the “Emergency
Operation” chapter 9, and use emergency
operation procedures to lower the platform.
Alternator Not Charging Alarm
❑
CAUTION
DO NOT continue to operate the AB50J while
the alternator alarm sounds. Without charging
current, the battery will discharge to the point
it cannot operate Emergency Power.
Axle Unlocked Alarm
❑
The front axle of the AB50J pivots so that all four
wheels remain on the ground when the machine
is driven with the main boom elevated less than
5° and the riser booms down. This improves
traction for 4-wheel drive machines and reduces
the ground pressure for all machines while they
are driven between work sites.
The main boom (more than 5°) and/or riser
booms should only be raised when the AB50J is
on a smooth level surface.When the main boom
is raised more than 5° or the riser booms are
raised slightly the front axle is automatically
forced to lock into position parallel to the rear axle
so that the bottoms of all four tires are in the
same plane.This maximizes stability of the
chassis while the booms are up.
If the engine alternator quits (usually because of
a broken fan belt), a continuous tone alarm will
automatically sound. The alarm warns you that
the battery is discharging.
Check the alternator drive belt to see if it is
broken or loose before you try to restart the
engine.If the engine will not restart, refer the
problem to a qualified service technician.
If the front axle is not locked parallel to the rear
axle when the main boom is raised more than 5°
or riser booms are raised, the TIP OVER
HAZARD light will come on and the “axle
unlocked”alarm will sound.
DANGER
DO NOT raise the main boom or riser booms
while the “axle unlocked”alarm is sounding.
CAUTION
When the alarm sounds you should
IMMEDIATELY lower the booms completely
down.Drive to a slightly different position, then
raise the booms again. If the alarm comes on
again, take the machine out of service
immediately and refer the problem to a
qualified service technician.
page 2 - 2 AB50J – 0163189
Tilt Alarm
❑
The tilt alarm warns the AB50J operator that the
AB50J is over 5° out of level.If the tilt continues
to increase, the AB50J will eventually tip over.
DANGER
To prevent Death or Serious Injury, when you
hear the loud two toned (high-low-high-low...)
alarm, 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.
All Motion Alarm
❑
The optional all motion alarm emits a loud
beeping sound anytime a platform moving switch
is used or anytime the DRIVE/STEER controller
is used. The alarm alerts people near the AB50J
that some part of the AB50J is moving.
Descending Boom Alarm
❑
The optional descending boom alarm emits a
loud beeping sound anytime the jib boom, main
boom, or riser booms come DOWN.The alarm
also sounds when the tip boom RETRACTS.The
alarm alerts people near the AB50J that a boom
is lowering.
2. Safety Devices
■
Other Safety Devices
Battery
❑
The battery in the AB50J is a safety device
because it powers the emergency operating
circuits.If the platform is aloft and the engine
dies, battery power is the only way to lower the
platform, there is no manual bleed down
procedure.Thus, battery maintenance is very
important. The battery should always be kept at
full charge and the battery terminals kept free of
corrosion.
❑
Drive Motion Alarm
The optional drive motion alarm emits a loud
beeping sound anytime the Drive/Steer controller
is in FORWARD or REVERSE. This alarm alerts
people on the ground that the AB50J is traveling
along the ground.
If an optional extra battery is installed, at rear of
turntable, it too is a safety device.The extra
battery is not connected to the standard battery.
The batteries alternate use: only one battery is
connected to the electrical system at a time. Each
time the starter motor is activated the battery
used changes.

Flashing Lights
❑
This switch must be pulled out (on) for anything
on the AB50J to work.
CAUTION
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 AB50J.
The optional flashing lights alert people that the
AB50J is present. The lights flash at about one
flash per second any time the Batter y,
Emergency Stop (at the ground), and Master
Key Switch are all ON.
There is no ON/OFF switch for the flashing lights.
page 2 - 4 AB50J – 0163189
2. Safety Devices
Foam Filled Tires
❑
Optional foam filled tires eliminate the possibility
of air leaks or blowouts which might cause a
tipover. Foam filled tires are therefore a safety
device.
Inspect them at the start of each work shift
according to the procedures in the “Daily
Inspection and Maintenance” chapter 7.
The foam filled tire shown here, shows signs of
damage and therefore is not acceptable for
service.
❑
Platform Foot Switch
Lanyard Anchor Points
❑
All personnel on the platform shall attach their fall
restraint lanyards to one of the lanyard anchor
points.
❑ Platform 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.
The platform foot switch prevents the platform
from moving if something accidentally pushes
one of the platform moving controls on the
platform control box.To make the platform move
you must step on the foot switch at the same time
you use a platform moving control.
AB50J – 0163189 page 2 - 5
2. Safety Devices
Ground Fault Circuit Interrupt
❑
The ground fault circuit interrupt (GFCI) is located
near the platform control box.
The GFCI protects against short circuits to
ground.When there is a short to ground the GFCI
shuts off power to the electrical outlets.
To use the outlet, connect the power input
connector, at the rear of the turntable, to a source
of 125 V AC, 15 A electrical power.
Platform Gravity Gate
❑
The platform gravity gate is the place in the
platform guardrail system where you should enter
and leave the platform.
If the AB50J has the optional AC Generator,
plug the power input connector into the
generator.Then, set the AC Generator switch,
on the platform control box, to ON.
See “electrical Outlet at the Platform” in the
“Operation” chapter 8, for more information
about how to use the GFCI.
Raise the gate and step under it onto the
platform.
CAUTION
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.
page 2 - 6 AB50J – 0163189
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. To make the platform
move you must push and hold the Ground
Operation switch up at the same time you use a
platform moving switch.
2. Safety Devices
Level Sensor
❑
The level sensor, located behind the ground
control box, detects how far out of level the
turntable is.
If the turntable gets over 5° out of level and the
booms are raised, the level sensor activates the
tilt alarm.
Platform Swinging Gate
❑
❑
Operator Horn
The optional operator Horn is used primarily to
get the attention of people on the ground when
you are working aloft. For the hor n to wor k the
