Lower controls
1. A red master switch push/pull button at the electrical junction box that will either turn
"ON" the electricity to both, the lower controls and to the upper controls and it will act
as an emergency stop at the lower controls. So, if this switch is in the "OFF" position,
both the lower and upper controls become inactive.
The lower portable controls are located on curbside. The station consists of five (5) toggle
switches that operate the following functions:
2. Lower boom up/down
3. Rotation CCW/CW
4. Upper boom extend/retract
5. Platform tilt
6. A three positions toggle switch “Emergency pump / Override switch”. The “Override”
position allows bypassing the upper controls to operate from the lower controls and
the “Emergency pump” position allows operation from the lower controls with the
Emergency pump.
Warning
The ‘’Override” position allows operation from the control toggle switches and
overrides the upper controls.
The “Emergency pump” switch is activated to run the pump while operating from
toggle switches on the portable control.
