If the machine does not work due to engine or main pump failure, use the emergency pump to lower the platform. To operate the boom and the fly jib using the emergency pump, operate each boom function or fly jib switch with the emergency pump switch held in its ON position.
Advice: It is not necessary to hold the dead-man switch in its ON position when operating the boom and the fly jib using the emergency pump.

Caution: l Operate the emergency pump every other 30 seconds. Continuous operation in excess of 30 seconds may damage the emergency pump. l Do not impose heavy load to the emergency pump, e.g. by attempting travel operation.
Advice: l In the event that the emergency stop switch has been pressed at the upper control with no operator on the platform and it is necessary to lower the platform, you can lower the platform using the emergency pump from the lower control. l The engine automatically stops as you operate the emergency pump from the lower control while the engine key switch is in its UPPER control position.
