1. About Your Aerial Platform
This section provides the general information about your
aerial platform. It describes the major components, table
of standard features & optional equipment, safety
reminders and precautions.
1.1 Major Assemblies
The aerial platform consists of three major assemblies:
the platform, the lifting mechanism and the base. An
operator’s control box is mounted on the platform
guardrail. Auxiliary and emergency controls are located
at the base.
1.2 Platform
The platform is constructed of a tubular support frame, a
skid-resistant “diamond plate” deck surface and
43-1/2" hinged guardrails with 6" toe boards and mid-
rails. The platform can be entered from either side
through a spring returned gate for Full Size RT's and from
the rear through a spring returned gate on Mid Size RT's.
The Mid Size RT's are equipped with a front extension
platform. The Full Size RT's can be equipped with a front
or both front and rear extension platforms.
1.3 Operator’s Control Box
A removable control box, mounted at the front right of
the platform, contains controls for aerial platform motion
and emergency stopping.
1.4 Manual Storage Box
This weather-resistant box is mounted to the inside of
the hydraulic cabinet door at the base or at the front of
the platform. It contains the Operating
Manual, the Operating/Maintenance
and Parts Manual and other important
documentation. The Operating Manual
for this make and model of aerial
platform MUST remain with the aerial
platform and should be stored in this
box.
1.5 Lifting Mechanism
The lifting mechanism is constructed of formed steel or
tube sections making up a scissor-type assembly. The
scissor assembly is raised and lowered by single-acting
hydraulic lift cylinders with holding valves. A two-section
pump, driven by an engine, provides hydraulic power to
the lift cylinders.
1.6 Maintenance Support
A maintenance support is located inside the lifting
mechanism. When properly positioned, it can support
the scissor assembly and empty platform. The
maintenance support MUST be used during inspection
and maintenance or when repairs are being performed
within the lifting mechanism.
1.7 Base - (Models 71xx & 8xxx)
The base is a rigid, one-piece weldment which supports
two side cabinets.
One cabinet contains the hydraulic components,
up/down controls and electrical components. The
other cabinet contains the fuel and hydraulic tanks.
The propane cylinder is either located behind the
access ladder or behind the fuel cabinet.
The front axle has two wheels, steerable by a
hydraulic cylinder and is either non-driven (2WD
models) or drive shaft/gear box driven (4WD
models).
The rear axle is drive shaft/gear box driven and
has a spring-applied hydraulically-released disc
parking brake.
A roll-out tray at the front of the base supports an
engine coupled with a two-section hydraulic pump
providing power to the hydraulic system.
An engine control panel is also located at the front
of the base.
The 12V starter battery is located in the hydraulic/
electric cabinet (Models 8831 & 8841) or at the
front of the engine roll-out tray (Models 71xx, 8243
& 8850).

1.9 Tilt Sensing System
The tilt sensing system located on the base of the aerial
platform is designed to prevent lifting or driving when
the machine is on a slope greater than a predetermined
limit. If in this situation the platform must be lowered
immediately.

Warning
Air pressure can affect stability. Temperature changes can affect air pressure. It is important to visually inspect all
tires for proper tire inflation prior to use. Tires should be checked by end user on a daily basis. Tire inflation
pressures must be checked weekly with a calibrated gauge. If the measured pressure is less than the specifica-
tion, reinflate to the pressure specified below. Tires must not be inflated above the recommended specification.
DO NOT intermix tires of different types on one machine. Use only tires of type originally supplied.
