METHOD FOR OPERATING ATTACHMENT
WARNING
If the travel levers or travel pedals are operated when the engine speed is decreased by the auto-decel-
eration function, the engine speed will suddenly increase. Be careful.
If you perform operations with your foot on the pedal, the attachment may suddenly move if you de-
press the pedal by mistake, and this may lead to serious personal injury or death. Do not rest your foot
on the pedal except when you operate the pedal.
When the attachment is not used, set the lock pin of the pedal to LOCK position to prevent the pedal
from being operated.
