ENERAL
ESCRIPTION
The SL26/30SL Work Platform consists of the plat-
form, controller, elevating assembly, leveling system,
power module, control module, and chassis
(Figure 1-1).
Platform
The platform has a reinforced wood floor, 43.5 inch
(1.11 m) high guardrails with midrail, 6 inch (152 mm)
toeboards and an entrance gate at the rear of the
platform. The guardrails can be folded down for
access through doors or for shipment, except when
equipped with the optional roll-out deck extension.
W A R N I N G
!
DO NOT use the maintenance platform without
guardrails properly assembled and in place with
fasteners properly torqued.
Controller
The controller contains the controls to operate the
machine. It should be hung on the front, left, or right
guardrail, but may be hand held if necessary. To
operate the machine, the interlock lever must be
depressed to operate any function. A complete expla-
nation of control functions can be found in Section 2.
Elevating Assembly
The platform is raised and lowered by the elevating
assembly, a two section arm pivoting on a gear, and
powered by a single stage lift cylinder. The hydraulic
pump, driven by the engine, actuates the cylinder.
Solenoid operated valves control raising & lowering.

Power Module
The power module contains the engine, hydraulic
pump, fuel tank, battery, and starter solenoid.
Control Module
The control module contains the hydraulic tank,
hydraulic valve manifold, horn/alarms, volt/hour
meter, electrical terminal strips, and chassis controls.
A complete explanation of the chassis control func-
tions is found in Section 2.
Leveling System
The base of the elevating assembly is mounted on
two pivots. Hydraulic cylinders at the side and rear of
the elevating assembly tilt the elevating assembly
and platform side to side or fore and aft. Instructions
for leveling the platform and elevating assembly are
found in Section 2.
Chassis
The chassis is a structural frame that supports all the
components of the SL26/30SL Work Platform.
Purpose of Equipment
The SL26/30SL Work Platform is designed to elevate
personnel and materials to overhead work areas and
be driven with the platform elevated on firm, level sur-
faces only.
Note: Travel with the platform raised is limited to
a creep speed range and will only travel if the
!
platform is less than 8 meters high
Special Limitations
The objective of the SL26/30SL is to provide a
quickly deployable, self-propelled, variable height
work platform for worksite use that can be driven over
rough terrain.
!
The elevating function shall ONLY be used
when the work platform is level and on a firm
surface. The work platform is NOT intended to
be driven over uneven, rough or soft terrain
when elevated.
