HIPMENT
1. Grease all the grease fittings (see Section 3).
2. Fully lower the platform.
3. Uncouple Anderson connectors to disconnect
batteries.
4. Band the controller to the front guardrail.
5. Band the elevating linkage to the frame.

TORAGE
No preparation for storage is required when the work
platform is in normal usage. Regular maintenance
procedures should continue to be performed (see
Section 3).
If the work platform is to be placed in long term stor-
age (dead storage), follow the recommended preser-
vation procedures, below.
PRESERVATION
1. Clean painted surfaces. If the paint is damaged,
repaint.
2. Fill the hydraulic tank to operating level, fluid will
be visible at the Sight Gauge. DO NOT fill the
hydraulic tank while the platform is elevated.
NOTE: DO NOT drain the hydraulic system prior
to long term storage.
3. Coat exposed portions of extended cylinder rods
with a preservative such as multipurpose grease
and wrap with barrier material.
4. Coat all exposed unpainted metal surfaces with
preservative.
BATTERIES
1. Disconnect the batteries negative (-) cables and
secure to the chassis.
2. Disconnect the remaining battery leads and
secure to the chassis.
3. Remove the batteries and place in alternate ser-
vice.

AISING THE
P
LATFORM
From the Platform Controls
1. Select platform at the Chassis/Platform Switch.
2. Select lift at the Drive/Lift Switch.
3. Push the Control Handle forward.
a. This will energize;
• the Drive/Lift Relay
• the Cutout Relay (the Cutout Relay will only
stay energized if the Level Sensor is level
within 2°)
• the Up Relay (completing the circuit to the
Up Solenoid Valve)
• and the Proportional Valve
b. This will allow oil flow;
• through the Proportional Valve (regulating
the speed to a rate which is proportional to
the angle of Control Handle deflection)
• through the Lift Valve
• through the Down Valve
• and to the Lift Cylinder (raising the Platform).
From the Chassis Controls
1. Select chassis at the Chassis/Platform Switch,
2. Press the Up Button
a. This will energize
• the Proportional Valve (regulating speed
through 10 ohm resistor)
• and the Lift Valve.
b. This will allow oil flow
• through the Proportional Valve (regulating
the speed to a fixed rate which is set by the
10 ohm resistor)
• through the Lift Valve
• through the Down Valve
• and to the Lift Cylinder (raising the Platform).
