4. Ensure the Emergency Main Power Disconnect
Switch is switched to the “OFF” position. Remove
the operator’s control box from its shipping
container and secure it to the guardrail at the right
front of the platform. Attach the control cable and
power extension deck cable (If Equipped) to the
machine’s control cable.
5. Move the aerial platform to a firm, level test area
where the platform can be later vertically extended
to its maximum working height. If the aerial
platform is to be pushed, towed or winched, Refer
to “section 2-26” for the proper guidelines for
“Winching and towing procedures.”

. Unlock and swing out the hydraulic/electric tray
and battery tray.
7. In the hydraulic/electric tray, check the tank’s
hydraulic oil level (scissors must be fully lowered).
Level should be at or slightly above the top mark
on the sight glass. Close the hydraulic/electric tray.
Note
If required, add a quality grade hydraulic oil such as
ATF Dexron III (ESSO). Never mix hydraulic oils.
For conditions below 32°F(0°C), an oil with a viscosity
range of 135-165SUS @ 100°F(40°C) (ISO Grade 32)
is recommended. For conditions above 32°F(0°C), an
oil with a viscosity range of 284-346SUS @
100°F(40°C) (ISO Grade 68) is recommended.
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.
8. In the battery tray, check the battery fluid level. If
fluid level is not at FULL mark on battery, add
distilled or demineralized water only.

“section 2-7” for proper procedure.) Lower the
platform until the scissor assembly is firmly
supported by the maintenance support.
5. Inspect all hoses, fittings, wires, cables, valves,
etc. for leaks, hidden damage and foreign material.
6. Raise the platform until there is an adequate
clearance to swing up maintenance support.
Return the maintenance support to storage
channel.
7. Raise the platform to the maximum extension
height.
Warning
To protect against unintended movement of the
aerial platform, push in the emergency stop button
after you have arrived at your desired location or
elevation.
8. Fully lower the platform.
9. Connect the A.C. battery charger cord to the
