OPERATOR’S
MANUAL
Part Number 0420453
March 2014
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 platform 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.

Safety devices reduce the likelihood of an accident. Never
disable, modify, or ignore any safety device. Safety alerts
in this manual indicate situations where accidents may
occur.
If any malfunction, hazard or potentially unsafe condition relating to capacity, intended use, or safe operation
is suspected, stop aerial platform operation and seek
assistance.
The operator bears ultimate responsibility for following
all manufacturer’s instructions and warnings, regulations
and safety rules of their employer and/or any state or
federal law.
Electrocution Hazards
The aerial platform is made of metal components and is
not insulated. Regard all conductors as energized. Do
not operate outside during a thunderstorm.
Minimum Safe Approach Distance
Minimum safe approach distances to energized power
lines and their associated parts must be observed while
operating the aerial platform.
Danger
The aerial platform is not electrically insulated. Death
or serious injury can result from contact with, or
inadequate clearance from, an energized conductor.
Do not go closer than the minimum safe approach
distance as defined by ANSI.
ANSI publications define minimum distances that must
be observed when working near bus bars and energized
power lines. Table 1 and Figure 3 are reprinted courtesy
of Scaffold Industry Association, ANSI/SIA A92.5.

Chapter 3 – Safety
Prestart Inspection
Perform a prestart inspection before each shift as described 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 (classified) 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.
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 materials 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 another platform.
Warning
The potential for an accident increases when operating an aerial platform that is damaged or malfunctioning. Death or serious injury can 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 obstruct your view below. Make sure the area below the
platform is free of personnel before lowering.
While operating the aerial platform, a good safety practice 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 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 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.
Tip-Over and Falling Hazards
Operate the aerial platform only on a firm, flat, level surface 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.
12 AB80J/AB85J – 0420453
Chapter 3 – Safety
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury can result from a tip-over accident. 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 structure 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 conditions. 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.
motion, reverse the control to free the platform. If control
reversal does not free the platform, evacuate the platform
before attempting to free it.
Electrical System
Charge the batteries in a well-ventilated area free of
flame, sparks, or other hazards that might cause fire or
explosion.

illness. Do not run the engine in an enclosed area or
indoors without adequate ventilation.
Chapter 3 – Safety
Operate dual fuel machines on LPG fuel when indoors to
reduce exhaust fumes and carbon monoxide.
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.
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.

CCA, 12 volt batteries. The batteries are behind the door
on the right side of the turntable (refer to Figure 7.8).
These batteries supply 12 volt DC electrical power to
operate the aerial platform electrical and electrohydraulic
components, including the emergency power system.
Terminals
Cables and Wiring Harness
Inspect all cables and wiring for wear and/or physical
damage such as loose connections, broken wires, and
frayed insulation. Check the wiring in areas where a
change in routing direction may cause them to become
pinched. Make sure the cables and wires are properly
routed to avoid sharp edges, pinching, and scuffing.
Hydraulic System
Hydraulic power is supplied from an engine driven variable displacement piston pump.
Danger
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

wheel lug nuts to see that none are missing, damaged,
or loose.
If necessary, remove the filler cap and add fluid of the
proper type. Refer to Chapter 2 for the proper type and
grade of hydraulic fluid to use. The need to regularly add
fluid indicates a leak that should be corrected.
The sight glass on the reservoir has an internal thermometer to measure the fluid temperature. The temperature
should be less than 200°F (93°C).
Fluid Filter
Checking the condition of the hydraulic fluid filter is part
of the machine maintenance schedule and should not be
performed by the operator.
Hoses, Tubes, and Fittings
Inspect all hydraulic hoses, tubes, and fittings for wear,
leakage, or damage (refer to Figure 7.10). Make sure the
hoses are properly routed to avoid sharp edges, kinking,
and scuffing. Inspect the tubes for dents or other damage
that may restrict fluid flow. Make sure all hoses and tubes
are held firmly in their support brackets.

Chapter 8 – Operation
The aerial platform may be operated from either the lower
or upper controls.
Danger
The aerial platform is not electrically insulated. Death
or serious injury can result from contact with, or
inadequate clearance from, an energized conductor.
Do not go closer than the minimum safe approach
distance as defined by ANSI.
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.
The aerial platform can tip over if it becomes unstable.
Death or serious injury can result from a tip-over
accident. Operate the aerial platform on a firm, flat,
level surface. Avoid travel speeds and/or rough terrain that could cause sudden changes in platform
position. 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.
The platform rated work load is the total weight of the personnel and equipment that may be lifted in the platform.
Cold, thick hydraulic oil does not flow well and may cause
delay in response to control movement and improper voltage output of the AC generator. Cold hydraulic oil may
also cause cavitation and pump damage. The hydraulic
system may be equipped with an optional cold weather
warm-up kit.
Engine Cold Weather Start Kit
The optional engine cold weather start kit may be an
engine block heater or a manifold air pre-heater. The
type of starting assist system depends on the engine
manufacturer.
The last two letters of the model number stamped on
the serial number placard indicates the engine manufacturer (refer to Figure 8.1). The serial number placard
is mounted on the front of the turntable.

Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury can result from a tip-over accident. Do not exceed the capacity values indicated
on the platform rating placard.
Capacity values indicate the rated lifting capacity and do
not indicate aerial platform stability.
The operator bears ultimate responsibility for ensuring
that the aerial platform is properly set up for the particular
conditions encountered.
Cold Weather Start-Up
If the ambient temperature is 32°F (0°C) or below, the
engine and hydraulic system oil may need to be warmed
before operation. Do not operate the engine at more than
a fast idle until the engine and hydraulic oil has had a
chance to warm. The engine may be equipped with an
optional cold weather start kit.
Cummins — Block Heater
Plug the heater cord into a 125 Volt AC, 600 watt source
eight hours before starting the engine. The heater will
warm the engine block to make cold weather starting
easier.
Unplug the power cord before starting the engine.
Deutz — Manifold Preheater
At the lower controls, hold the manifold heater switch on
for about a minute before starting the engine. A glow plug
in the manifold preheats the air to help start the engine.
Continue to hold the switch while starting the engine. Do
not release the switch until the engine starts.
If the engine does not start within 20 seconds, continue
to hold the manifold heater switch and turn the start
switch off. Wait for one minute before trying to start the
engine again.
GM — Radiator Hose In-Line
Plug the heater cord into a 125 Volt AC, 600 watt source
eight hours before starting the engine. The heater will
warm the water in the lower radiator hose to make cold
weather starting easier.
Unplug the power cord before starting the engine.
AB80J/AB85J – 0420453 47
Chapter 8 – Operation
Hydraulic System Cold Weather Warm-Up
Some machines may have a hydraulic fluid warm-up
system that will automatically warm the fluid upon activating the warm-up switch. The hydraulic fluid may also
be warmed manually if the machine is not equipped with
the optional warm-up system.
Caution
Not all hydraulic fluid is suitable to use in the hydraulic system. Some have poor lubricating characteristics and can increase component wear. Only use
hydraulic fluid as recommended.
Use cold weather hydraulic oil as recommended in the
machine General Specifications in temperatures of 10°F
(0°C) or below.
Hydraulic System Warm-up Switch
This system may be used to warm the hydraulic fluid when
the ambient temperature is below 32°F (0°C) and boom
movement is sluggish because of cold fluid.
There may be a toggle switch for the warm-up system
on the lower control panel and/or one on the left side of
the upper control panel.
The engine must be running and the switch used to turn
the system on must be at the same location that the engine was started. For example, if the engine was started
from the lower controls, the warm-up switch at the lower
controls must be used for the system to operate.
Use cold weather hydraulic oil as recommended in the
machine General Specifications in temperatures of 10°F
(0°C) or below.
Preparing for Operation
Use the following procedure to prepare the aerial platform
for operation.
1.
Perform a prestart inspection as described in Chapter 7.
2. Place the battery disconnect switch in the on position.
3. Close and latch the doors.
4. Before painting or sandblasting make sure the sandblast protection kit and the platform control cover are
properly installed. These options, when used properly
will protect the control placards and cylinder rods from
paint overspray and abrasion while sandblasting.
Lower Controls
The lower controls override the upper controls. This
means that the lower controls can always be used to
operate the platform regardless of the position of the
upper control emergency stop button.
Boom, turntable, and platform functions may be operated
from the lower controls. The lower controls may be used
for initial set up of the aerial platform, and for testing and
inspection.
To operate the warm-up system:
1. Start the engine and place the engine throttle in the
low position.
2. From the same control station that the engine was
started, place the warm-up switch in the on position.
3. After the hydraulic fluid reaches 50°F (10°C) as indicated on the thermometer, place the warm-up switch
in the off position.
Manually Warming The Hydraulic System
The hydraulic oil may be warmed by bottoming out the
boom extension cylinder. Raise the main boom so it is
horizontal and operate the boom retract function while the
machine is stowed. With the cylinder bottomed out the oil
flow will produce heat to warm the hydraulic oil.
Caution
Not all hydraulic fluid is suitable to use in the hydraulic system. Some have poor lubricating characteristics and can increase component wear. Only use
hydraulic fluid as recommended.
Use the following procedure to operate boom, turntable,
or platform functions using the lower controls.
1. On dual fuel machines, set the fuel switch to either
LPG or gasoline.
2. Open the shut-off valve on the tank if using LPG.
3. Place the emergency stop switch (refer to Figure 8.2)
in the on position and place the controls switch in the
ground position.

points.
4. Turn the start switch to on and pause a few seconds
while the alarm sounds to alert others that the machine is about to start. Turn the switch to start, then
release it to on. The engine will not start if the switch is
left in the on position for 30 seconds or longer before
turning it to start. The switch must be turned back to
off before the engine will start.
Note
If the machine has a GM engine, there will be a 7 to 10
second delay after starting the engine, before the throttle
will go to mid or high. Start the engine and wait 10 seconds
before proceeding with machine operation.
5. Let the engine warm to operating temperature.
6. Turn the boom speed knob to slow.
7. Hold the ground operation switch in the on position
while operating the boom and turntable control toggle
switches.
8. Hold the appropriate toggle switch in the desired
direction.

Boom Operation
Use the following procedure to operate the turntable,
boom, or platform functions.
1. Step down on the platform foot switch (refer to Figure
8.4). This switch must be held down to operate the
upper controls.
jib be elevated just enough to provide adequate ground
clearance.
A 30 percent grade is a 36″ (0.91 m) vertical rise in 10′
(3.05 m) horizontal length.
Avoid driving with the platform over the front end of the
chassis. In this position the machine is difficult to control
because:
• drive and steer control movements and their resulting
machine movements are reversed.
• when driving fast, sudden turns or stops produce
more severe reactions to platform occupants.
• more turning space is required to prevent the platform
from colliding with obstacles several feet beyond the
path of the tires.
Warning
Death or serious injury can result from improperly
driving or steering the aerial platform. Read and understand the information in this manual and on the
placards and decals on the machine before operating
the aerial platform on the job.

Hold the appropriate control in the desired direction.
As the main boom is raised on AB85J machines, the
tip boom is extended a maximum of 30″ (76.2 cm).
Always look in the direction of movement.
3. Releasing the control to its neutral position, or releasing the foot switch will stop movement.
Driving and Steering
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury can result from a tip-over
accident. Do not drive an elevated aerial platform on
soft, uneven, or sloping surfaces. Do not drive the
machine on grades that exceed 30 percent.
For operation on grades up to 30 percent, it is recommended that the main boom be near horizontal and the
The blue and yellow arrows on the chassis indicate the
direction the chassis will move when the drive or steer
control is moved toward the corresponding color.
When the machine is in the stowed position, with the
booms centered between the rear wheels, the direction
of drive and steer control movement corresponds with
the direction of chassis movement.
When the turntable is rotated from the stowed position,
with the booms to either side of or in front of the chassis,
the direction of control movement does not correspond
with the direction of chassis movement.
To avoid confusion, always drive to the work area or
move between work areas with the turntable and booms
in the stowed position. After arriving at the work area, the
booms may be positioned to the side or the front of the
chassis for final positioning. Always look in the direction
of movement as indicated by the directional arrows on
the chassis.
Use the following procedure to operate the drive and
steer functions.
1. Determine the desired drive range for the specific
driving conditions. Place the switch in the appropriate
position to achieve the desired drive wheel operation.
• Use high range (two wheel drive) when traveling
across firm, flat, level surfaces. High range can only
be activated when the booms are stowed. High
range is for high speed, low torque operation.
50 AB80J/AB85J – 0420453
Chapter 8 – Operation
• Use mid range (four wheel drive) when traveling
across soft surfaces or those with small inclines.
Mid range can only be activated when the booms
are stowed. Mid range is for medium speed, high
torque operation.
• Use low range (four wheel drive) for driving on
loading ramps or other steep grades and when
safety considerations demand slow deliberate
machine movement. Low range is for low speed,
high torque operation.
2. Determine the desired steer mode for the specific
driving conditions. Place the switch in the four wheel
coordinated, two wheel, or crab steer mode position
to achieve the desired machine movement. Refer to
Figure 8.5

Figure 8.5 – Steer Modes
5. To stop drive motion, return the joystick to neutral.
6. Push the drive joystick to the right to steer to the right,
the direction of the yellow arrow. Push the joystick
to the left to steer to the left, the direction of the blue
arrow. The wheels will steer only when the drive
joystick is in the forward or reverse drive position, or
when the booms are stowed.
Note
The steering wheels are not self-centering. Set the steering wheels straight ahead after completing a turn.
7. After driving to the desired location, release the foot
switch, or push the emergency stop button to apply
the parking brakes.
Drive Speeds
The drive speed is proportional to the joystick position.
The farther the joystick is moved, the faster the travel
speed.
Always slow down and shift the drive system to low
range before traveling over rough terrain or any sloped
surface.
Drive speed ranges are interlocked through limit switches
that sense the main and riser boom position. When either
boom is elevated or extended, only the slowest drive
speed will work regardless of the drive range switch position. To avoid a sudden speed change from high to low
elevated boom speed, always bring the machine to a stop
before raising the booms from the stowed position.
• Use two wheel steer for most machine operation
such as travel between jobs and to position the
machine near the job location.
• Use four wheel coordinated steer when a tight turning radius is desired for positioning the machine.
• Use crab steer to travel in a diagonal motion in the
direction of the wheels.
Note
The steering wheels are not self-centering. Set the steering wheels straight ahead after completing a turn and
before switching from one steer mode to another.
3. Step down on the platform foot switch.
4. Push the drive joystick forward to move the chassis forward, the direction of the blue arrow. Pull the
joystick backward to move the chassis backward,
the direction of the yellow arrow. The drive speed is
proportional to the joystick position.
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.
Do not use the aerial platform if it drives faster than 0.6
miles per hour (26 feet in 30 seconds) when any of the
booms are out of the stowed position.
Motion Warning Alarm
The motion warning alarm sounds loud intermittent beeps
when the drive joystick is in the forward or reverse position.
Gradeability
Machine gradeability refers to the maximum slope that
the aerial platform is capable of travel under practical
conditions. It is based on mathematical calculation, but
it also takes into account the practical application.
At any given moment when driving the machine on a
slope, at least one, if not all, of the factors contributing
to achieving theoretical gradeabilty will not be at optimal
performance. For example, tire contact may not be the
same at each drive wheel or the slope conditions may not
be optimal, which would then allow for loss of traction.
AB80J/AB85J – 0420453 51
Chapter 8 – Operation
Percent vs. Degree of Slope
Gradeability is most often referenced as a percentage.
That value is based on a slope angle of 45° representing
100% grade.
Angle indicators, or inclinometers, often measure the
angle of the slope in degrees not the percent slope.
Because of that, it may be useful to understand the relationship between percent slope and the degree of the
slope angle as shown in Figure 8.6.
Driving on a Slope
The machine should only be driven on a slope or loading ramp in the stowed position with the platform on the
downhill side.
Angle of Slope
in Degrees
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury can result from a tip-over accident. Do not drive on slopes that exceed 30 percent
grade, or where conditions of the slope could cause
driving to be hazardous.
Place the drive range switch in the low position before
attempting to drive the machine on a slope.
Drive the aerial platform only on slopes, or loading ramps
that are within the 30 percent grade capability of the
aerial platform.
Calculate the percent grade:
• before attempting to climb an unknown grade
• if it is believed that there is a malfunction to determine
if the slope is within the actual grade capability of the
aerial platform.

Calculating Percent Grade
The percent grade equals the height (rise) of the slope divided by the length (run) times 100. Refer to Figure 8.7.
Figure 8.7 – Percent Grade Formula
The grade can be measured with an inclinometer or by
using a tape measure, a level, and a straight 2x4. If using an inclinometer, refer to the conversion diagram if
necessary.
To measure the grade without an inclinometer, use the
following procedure.
1. With the 2x4 laying parallel with the slope, lay the
level lengthwise on the 2 x 4.
2. Holding the downhill end, raise the 2x4 until the
level indicates that the board is level (refer to Figure
8.8).
Electrical Power Outlet
The electrical outlet at the platform has 2, 3-prong, 125
volt AC electrical connectors. Their combined output is
limited by a 15 amp circuit breaker.
Power may be supplied to the outlet using an external
power source or by operating the optional AC generator.
To use the outlet, plug a source of power into the powerinput connector on the left side of the turntable (refer to
Figure 8.9). Unplug the source of power before moving
the aerial platform.

AC Generator
The generator supplies power to the electrical outlet only
when the engine is running and the machine is stationary.
The machine functions will not operate when the machine/

Caution
Cold hydraulic oil does not flow well and may produce
improper generator output voltage. Improper outlet
voltage can damage some electrical power tools and
equipment. Warm the hydraulic oil before operating
the generator.
Do not operate the generator unless the hydraulic oil tem-

3. Use the tape measure to measure the distance
(height) from the end of the 2x4 to the ground. Record
the height distance.
4. Measure the length of the 2x4 and record this measurement.
5. Use the formula in Figure 9.2 to calculate the percent
of the grade.
Machine Gradeability
The gradeability specification for the AB80J/A80J and
AB85J/A85JRT aerial platforms is 20%. An actual gradeability of 20%, indicates that in most normal working
conditions the machine can be driven on a slope with an
angle of 11.3 degrees.
AB80J/AB85J – 0420453 53

Start-Up for a hydraulic oil warm-up procedure.
Use the following procedure to supply power to the electrical power outlet if the machine is equipped with the
optional generator.
1. Plug the generator cord into the outlet on the left side
of the turntable (refer to Figure 8.9).
2.
Start the engine and place the machine/generator
switch (refer to Figure 8.10) in the generator position.

center of gravity – the point in the aerial platform around which its weight
is evenly balanced.
chassis – the integral part of the aerial platform that provides mobility and
support for the booms.
fall restraint – a system that is used while working on a boom lift within the
boundaries of platform guardrails to provide restraint from being projected
upward from the platform. This system includes a harness or belt, lanyard,
and a lanyard anchor. Federal OSHA, ANSI, and Snorkel require the use of
additional fall protection beyond the platform guardrails on boom supported
aerial platforms.
floor or ground pressure – the maximum pressure, expressed in pounds
per square inch, a single wheel concentrates on the floor or ground.
gradeability – the maximum slope that the aerial platform is capable of
travel.
ground fault circuit interrupter (GFCI) – a fast-acting circuit breaker that
opens to stop electrical circuit flow if it senses a very small current leakage
to ground. The GFCI is used to protect personnel against a potential shock
hazard from defective electrical tools or wiring.
guardrail system – a vertical barrier around the platform to prevent personnel from falling.
maximum wheel load – the load or weight that can be transmitted through
a single wheel to the floor or ground.
Minimum Safe Approach Distance – the minimum safe distance that
electrical conductors may be approached when using the aerial platform.
Also called M.S.A.D.
operation – the performance of any aerial platform functions within the scope
of its specifications and in accordance with the manufacturer’s instructions,
the users work rules, and all applicable governmental regulations.
operator – a qualified person who controls the movement of an aerial
platform.
personal fall arrest system – a fall protection system that is used while
working on an unprotected edge (such as a roof top with no guardrail). This
system includes a harness, lanyard or other connecting device, a fall arrestor,
an energy absorber or decelerator, an anchorage connector, and a secure
anchorage such as a building beam, girders or columns. An aerial platform
is not a fall arrest anchorage.
platform – the portion of an aerial platform intended to be occupied by
personnel with their tools and materials.
platform height – the vertical distance measured from the floor of the platform to the surface upon which the chassis is being supported.
prestart inspection – a required safety inspection routine that is performed
daily before operating the aerial platform.
qualified person – a person, who by reason of knowledge, experience,
or training is familiar with the operation to be performed and the hazards
involved.
rated work load – the designed carrying capacity of the aerial platform as
specified by the manufacturer.
riser – the structure that connects the riser boom to the main boom.
riser boom – an articulating boom section. The riser boom is between the
turntable and the main boom.
stow – to place a component, such as the platform, in its rest position.
hazardous location – any location that contains, or has the potential to
contain, an explosive or flammable atmosphere as defined by ANSI/NFPA
505.
interactive link – the structure connecting the extend cylinder assembly to
the turntable, increasing the reach of the tip boom.
jib – an articulating boom attached to the tip boom which increases the
overall boom reach.
level sensor – a device that detects a preset degree of variation from perfect
level. The level sensor is used to sound an alarm if operating on a slope
greater than the preset value.
lower controls – the controls located at ground level for operating some or
all of the functions of the aerial platform.
main boom – a boom assembly located between the riser and the jib.
manufacturer – a person or entity who makes, builds or produces an
aerial platform.
maximum travel height – the maximum platform height or the most adverse
configuration(s) with respect to stability in which travel is permitted by the
manufacturer.
tip boom – a telescopic boom section that extends and retracts from within
the main boom. The tip boom is nearest the platform.
turning radius – the radius of the circle created by the wheel during a 360°
turn with the steering wheels turned to maximum. Inside turning radius is the
wheel closest to the center and outside turning radius is the wheel farthest
from the center.
turntable – the structure above the rotation bearing which supports the
booms. The turntable rotates about the centerline of rotation.
unrestricted rated work load – the maximum designed carrying capacity
of the aerial platform allowed by the manufacturer in all operating configurations.
upper controls – the controls located on or beside the platform used for
operating some or all of the functions of the aerial platform.
wheelbase – the distance from the center of the rear wheel to the center
of the front wheel.
working envelope – the area defined by the horizontal and vertical limits
of boom travel that the platform may be positioned in.
working height – platform height plus six feet.
