ATTACHMENTS AND OPTIONS MACHINE READY FOR ATTACHMENT

Operation When Using Attachment 2 (e.g clamshell rotation, crusher rotation) 6
Note - If installing 2nd attachment line as a field kit, ask distributor to change monitor setting to allow 2 attach-
ments.
The switch on left lever is a roller proportional control switch.
Rolling the switch up produces rotation in one direction, rolling
down produces rotation in the opposite direction. Slight move-
ment of the roller will give slight movement of the attachment;
full movement of the roller will give faster movement of the
attachment.
If the working mode pilot monitor does not display ATT for the
attachment mode, follow the instructions on page 6-24.
LONG TERM STORAGE 6
If the equipment is not to be used for a long time, do as follows.
q Set the stop valve in the LOCK condition.
q Fit a plug at the tip of the stop valve piping.
q Set the lock pin at the LOCK position.
If there is no breaker or general attachment installed, operating the pedal may cause overheating and other prob-
lems.
