EMERGENCY LOWERING PROCEDURE
In an emergency, a person at floor level can lower
the platform by holding the UPPER
CONTROL/OFF/LOWER CONTROL key switch in
the LOWER CONTROL position and turning the
UP/DOWN selector switch to the DOWN position. (If
the upper control box emergency stop pushbutton is
depressed, the platform will not lower.)
An emergency lowering valve is shown in Figure 3-4.
In case of a total loss of battery power, a person at
floor level can safely lower the platform by opening
the emergency lowering valve.
WARNING
Do not climb out of the lift cage while the lift
platform is elevated. The lift mast cannot be
climbed safely. An elevated lift platform has a
high center of gravity and can be tipped easily.
Standing on or leaning out from the outside of
a cage rail may cause the lift vehicle to tip over.
Tipping the lift vehicle over can cause severe
injury or death and equipment damage.
If you lose power while elevated in the cage, instruct
someone on ground level to open the emergency
lowering valve. Do not
leave the cage to climb down
the lift mast or storage shelves.
To lower the platform, pull and hold the red valve
knob until the platform starts to descend. When the
platform is fully lowered, release the knob to close
the valve.
