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 defi ned 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.

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 fl ow 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 fl oor 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
confi gurations
Before using the aerial platform in any hazardous (classifi ed) location, make certain it is approved and of the
type required for use in that particular location.
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.
AWarning
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. Qualifi ed 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.
Know and understand the job site traffi c-fl ow patterns
and obey the fl agmen, road signs and signals.
While operating the aerial platform, a good safety
practice is to have qualifi ed 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
ADanger
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
suffi cient clearance around the machine before mov-
ing the chassis, booms, or platform. Allow suffi cient
room and time to stop movement to avoid contact
with structures or other hazards.
Never cover the platform fl oor 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 fi rmly on the platform fl oor.
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 fi rm, fl at, level
surface capable of withstanding all load forces imposed
by the aerial platform in all operating conditions. Refer to
the General Specifi cations chart for the maximum wheel
load and ground pressure. Raise the booms only when
the aerial platform is on level ground.
8 SB126J – 0192278
Chapter 3 – Safety
ADanger
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. Do not
raise the boom in winds above 45 km/h (28 mph).
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, fl ags, 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.
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.
Electrical System
Charge the batteries in a well-ventilated area free of
fl ame, sparks, or other hazards that might cause fi re
or explosion.
Do not operate any of the aerial platform functions while
the battery charger is plugged in.
AWarning
Batteries give off hydrogen and oxygen that can
combine explosively. Death or serious injury can
result from a chemical explosion. Do not smoke or
permit open fl ames or sparks when checking the
batteries.
Battery acid can damage the skin and eyes. Serious
infection or reaction can result if medical treatment
is not given immediately. Wear face and eye protection when working near the batteries.
Batteries contain sulfuric acid that can damage your eyes
or skin on contact. Wear a face shield, rubber gloves,
and protective clothing when working around batteries.
If acid contacts your eyes, fl ush immediately with clear
water and get medical attention. If acid contacts your

Engine exhaust contains carbon monoxide, a poisonous gas that is invisible and odorless. Breathing
engine exhaust fumes can 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 fl ames while fueling or
near fueling operations.
Never remove the fuel cap or fi ll the fuel tank while the
engine is running or hot. Never allow fuel to spill on hot
machine components.
Maintain control of the fuel fi ller nozzle when fi lling the
tank. Spilled fuel is a potential fi re hazard.
Do not overfi ll the fuel tank. Allow room for expansion.
Tighten the fuel tank cap securely. If the fuel cap is lost,
replace it with an approved cap from UpRight. 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.

are not properly extended and locked in position.
Figure 4.7 – Optional Swinging Gate
12 SB126J – 0192278
Chapter 4 – Safety Devices
The gates close automatically after entering or exiting
the platform. The gate is part of the guardrail system and
must be securely fastened after entering the platform.
Lanyard Anchors
Two lanyard anchors for fall restraint anchorage are
provided below the upper controls at the front of the
platform (refer to Figure 4.6).
Note
The lanyard anchors are not for lifting or tying the machine down.
All personnel in the platform must connect their fall
restraint device to a lanyard anchor before raising the
platform. Do not use the aerial platform for personal fall
arrest anchorage.
Envelope Management System
The Envelope Management System (EMS) restricts the
movement of the platform to keep it within safe work
parameters. There are EMS indicator lights on the upper
and lower controls (refer to Figure 4.8).
The red EMS light/button will only be lit in the case of a
malfunction with the EMS system. The red button/light
will fl ash and beep in quick pulses then pause and re-
peat if the primary envelope has been exceeded. When
the red button/light emits a continuous series of beeps
and fl ashes, the primary and backup envelopes have
been exceeded. The display of a solid red light, with
solid tone, is indicative of system or electrical failures or
further extension beyond the backup envelope. If, after
resetting the EMS system, the solid red light reoccurs, an
UpRight authorized service provider must be contacted
before any further operation.
When the machine is fi rst started or after the EMS has
been reset, there will be a 7 to 10 second delay before
the EMS system will be operational. During this delay
period the green light will not be on and the EMS functions will not be operational.
Height Restriction
The EMS has a height restriction feature which allows
the machine owner to limit the maximum height the platform will reach. The maximum height display is located
on the wiring box on the left side of the machine (refer
to Figure 4.9). If the height has been restricted the word
LIMIT will be displayed in the lower right corner.

The white EMS light will begin to fl ash as the platform
approaches the edge of the working envelope. A solid
white light indicates the edge of the working envelope
has been reached. In the advent of a solid white light,
the EMS will restrict one or more types of movement to
keep the platform within the working envelope.

Tilt Alarm
If the aerial platform chassis is out of level more than
3.5 degrees when the main boom is raised or extended,
an alarm will sound. The tilt alarm is located under the
upper control panel.
ADanger
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.
When the tilt alarm sounds, completely retract and lower
the main boom and then drive to a level surface. The tilt
alarm is for added protection and does not justify operating on anything other than fi rm, fl at, level surfaces.

Platform Overload Sensing System
All functions are stopped from the upper and lower
controls, when the platform overload limit is exceeded.
The horn will sound intermittently and the red overload
light (refer to Figure 4.10) will blink until the excess load
is removed from the platform. At that time, the machine
functions are again operational.
Platform
Overload Light
Figure 4.10 – Upper Controls
If the platform becomes signifi cantly overloaded, or if
an upward force on the platform exceeds approximately
445 N (100 lb), the system will enter into error mode,
stopping all functions from the upper and lower controls.
The horn will then sound constantly and the overload
light will stay illuminated at the upper and lower controls
(refer to Figures 4.10 and 4.11).
Engine
Temperature
Gauge
The system will remain in error mode until the excess
load is removed from the platform and the emergency
stop button or start switch is cycled off and back on,
resetting the system. At that time, the machine functions
are operational.
ACaution
The emergency power system is for emergency
lowering and stowing only. The length of time the
pump can be operated depends on the capacity
of the battery. Do not use this system for normal
operation.
If the platform overload sensing system is tripped while
operating the machine or if the system is in error mode
and can not be reset, the emergency power system
may still be used for emergency machine operation from
either the lower or upper controls.
ADanger
The aerial platform can tip over if it becomes unstable. Death or serious injury will result from a
tip-over accident. Do not exceed the capacity values
indicated on the platform rating placard.
The overload sensing system is not active when the
machine is being driven with the booms in the stowed
position. This allows the machine to be driven without
the system sensing an overload due to rough ground
conditions.
To eliminate repeated tripping of the system during machine operation, there is a fi ve second delay in machine
functions following:
• starting the engine.
• placing the drive/boom selector switch in the boom
position when the main boom is below horizontal
and fully retracted.
• removing excess load from the platform.
Engine Protection Systems
A light in the emergency stop button will illuminate to
warn against high engine temperature.
The engine will shutdown if the operating temperature
exceeds a preset level or if the oil pressure is too low for

safe operation. An engine temperature gauge is on the
top of the lower control panel (refer to Figure 4.11).
High Engine Temperature Alarm
If the coolant exceeds the engine operating temperature,
a light in the emergency stop button will illuminate and
the engine will shut off.
Do not restart the engine until the condition that caused
the overheating has been corrected.
Chapter 4 – Safety Devices
Low Oil Pressure Alarm
The low pressure oil alarm sounds when the engine oil
pressure is near the lower limit for safe engine operation.
If the alarm sounds, lower the platform to the ground
and then turn the engine off. Do not restart the engine
until the condition that caused the low oil pressure has
been corrected.
If the engine oil pressure falls below a safe operating
value the engine will shut off. The engine can be restarted with low oil pressure, but it will only run a few
seconds before it shuts off again.
Horn
The horn may be used to warn personnel on the ground.
The horn button is on the right side of the upper control
panel (refer to Figure 4.12). The horn is operational when
the emergency stop button and the start switches are
both on at the lower and the upper controls.
