(1) PTO (Power Take Off) switch
When the PTO switch is set to the "ON" position, the pump is
driven, power is supplied to the ACS and the slewing stop circuit is
released. The PTO indicator lamp on the switch panel lights to tell
the operator that crane operation is possible.
・ Lock the suspension before you turn the PTO switch "ON".
If you turn the PTO switch "ON" without locking the suspension, the suspension lock
cylinders will lock where they are at different stages of extension.
・
If you lock the suspension lock cylinders without fully retracting them and attempt any crane
operations without the outriggers, the body will not be level and the crane will tip over.
・ Fully retract and lock the suspension cylinders regardless of whether or not the outriggers will
be used to turn the PTO switch "ON" before you start crane operation.

・
Before you set the PTO switch to the "ON" position, confirm that the needle of the engine
water temperature gauge is above point "C". Setting the PTO switch to the "ON" position
while the engine coolant temperature is low could cause a seizure, fast wear, damage etc. due
to poor lubrication (from high oil viscosity) of the engine and torque converter.
・ Before you work the PTO switch, take your foot off the accelerator pedal so that the engine is
idling.
・ When the PTO switch is switched "OFF", the brake will be applied automatically to
immobilize the superstructure regardless of the slewing brake switch position.
・ Before you drive on the road, move the superstructure to the driving position, engage the
slewing lock, stow the outriggers and set the PTO switch to the "OFF" position to return the
suspension to the driving position (suspension free state).
