elevated driving MUST be on a flat, level, compacted
surface. The work platform can be driven over uneven
terrain only when the platform is fully lowered.

Warnings

The operator MUST read and completely understand
the safety panel labels and ALL other warnings in this
manual and on the work platform. Compare the labels
on the work platform with the labels found throughout
this manual. If any labels are damaged or missing,

Description

The work platform consists of three major assemblies,
the platform, lifting mechanism and the base.
operator's control box is mounted on the platform
railing. Auxiliary and emergency controls are located at
the base.
Platform
- The platform is constructed of a tubular
support frame, a skid-resistant "diamond plate" deck
surface, and 43-1/2" (1.10m) hinged railings with 6"
(15.24cm) toe boards and mid-rails. The platform can
be entered from the rear through a spring returned
gate. The 600 Series can be equipped with a front
extension platform.

Lifting Mechanism

constructed of formed steel sections making up a
scissor-type assembly. The scissor-type 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. A safety bar located inside the lifting
mechanism (when properly positioned) prevents the
scissor-type assembly from being lowered while
maintenance or repairs are being performed within the
lifting mechanism.

The base is a rigid one piece weldment which
supports two component side cabinets. One cabinet
contains the hydraulic components, up/down controls,
electrical components and starter battery. The other
cabinet contains the fuel tank and hydraulic tank. The
LP tank (if equipped) is located at the rear of the
platform behind the entrance ladder. 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 slide-out drawer 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.
Operator's Control Box
box, mounted at the right front of the platform, contains
controls for engine operation, work platform motion
and emergency stopping.
