Section 1 - About Your Aerial Platform

1. About Your Aerial Platform

This section provides general information about your
aerial platform. It describes the major components,
standard and optional features, 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 one of the platform
guardrails. 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"
(1100mm) hinged guardrails with 6" (152mm) toe boards
and mid-rails. The platform can be entered from either
side through a spring-returned gate . All models can be
equipped with a front or both front and rear extension
platform.

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

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 single-section pump,
driven by an electric traction motor through a gear box,
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

The base is a rigid, one-piece weldment which supports
two component side cabinets.

• One cabinet contains the hydraulic components,
up/down controls and electrical components.

• The other cabinet contains the hydraulic tank and
the battery chargers.

• The front axle has two wheels, steerable by a
hydraulic cylinder and is non-driven or drive shaft/
gear box driven (4WD option).

1

This weather-resistant box is mounted inside the door of
the hydraulic cabinet located at the base. 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.

SJ800 - E Series
Battery Powered

• The rear axle is drive shaft/gear box driven and
has a spring-applied hydraulically-released disc
parking brake.

• The drive system is designed to automatically
adjust to rough terrain or steep inclines.

• A slide-out drawer at the front of the base, supports
a battery compartment which provides power to
the electrical system.

Section 1 - About Your Aerial Platform

1.8 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 fully lowered
immediately.

1.9 Load Sensing System

The load sensing system is a safety device that prevents
any normal movement of the aerial platform from a
stationary working condition after the rated load is
reached and exceeded.

1.10 Lowering Warning System

A lowering warning system automatically stops the low­ering function before reaching the fully retracted posi­tion and sounds the alarm.

1.11 Serial Number Nameplate

The serial number nameplate, located at the rear of the
machine, lists the following:

• Model number

• Serial number

• Machine weight

• Maximum drivable height

• Maximum capacities

• Maximum number of persons permissible on the
platform

• Voltage

• System pressure

• Lift pressure

• Maximum platform height

• Maximum wheel load

Section 2 - Operation Battery Maintenance

2.9 Battery Maintenance

This section provides the operator with procedures on
how to service and charge the battery. This also
provides charger operation instructions.

2.9-1 Battery Service Procedures

Warning

Explosion Hazard

Keep flames and sparks away.

Do not smoke near batteries.

Warning

Battery acid is extremely corrosive

Wear proper eye and facial protection as well as

appropriate protective clothing.

If contact occurs, immediately flush with cold

water and seek medical attention.

2.9-2 Battery Charging Operation

Figure 2-21. Battery Charger

Danger

Risk of electric shock

Do not immerse the charger in water.

Though the charger is highly resistant to water, it is

not designed for immersion and an electric shock

can occur.

1. Ensure that the battery connector is properly
connected.

2. Check battery case for damage.

3. Check battery fluid level in each battery. If plates
are not covered by at least 1/2” (13mm) of
solution, add distilled or demineralized water.

4. Clean battery terminals and cable ends thoroughly
with a terminal cleaning tool or wire brush.

5. Make sure all battery connections are tight.

6. Replace any battery that is damaged or incapable
of holding a lasting charge.

7. Do not use any batteries other than flooded lead­acid batteries of the proper AH rating.

Warning

1. Provide adequate ventilation for the batteries and
charger. The convection cooled design requires
access to cooling air for proper operation. Do
not allow blankets or other materials to cover the
charger. Although the charger protects itself
against overheating, the charger cooling fins
should be cleaned if clogged with debris for best
performance.

Warning

There could be a spark during charging. Be careful

when using fuels, solvents or other flammables near

the charger or batteries.

2. Connect the power supply cord to a properly
grounded 100V/50 or 60Hz, 115V/50 or 60Hz, or
230V/50 or 60Hz socket. This charger
automatically senses and adjusts to the AC input
voltage range.

Use original or equivalent to the original parts and

components for the aerial platform.

AC supply is not being switched-off at night with other
building items. Check battery condition and for dead
cells or reduced capacity. Replace charger only if other
problems are not found.

The AC line circuit breaker or fuse is blown.

A defective circuit breaker or fuse, an overloaded cir­cuit, or a charger problem can cause this condition. Try
connecting the charger to a different AC outlet (on a
different circuit) in the building. If the AC supply checks
good, the charger should be replaced.
