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.
