WARNING
q
Emergency stop
If a failure has occurred or an anomaly has been observed, turn the ignition key to position OFF.
q
If the work equipment is operated without warming up the engine sufficiently, the response of the work
equipment to the movements of the control lever will be slow, and the work equipment may not move
as desired by the operator, so always carry out the warming up procedure. Particularly in cold areas,
be sure to carry out the warming up procedure correctly.
