With the working mode set at ATT mode, insert the lock pin in
FREE position (c) for both front and rear. Depress the front or

METHOD FOR OPERATION WHEN USING GENERAL ATTACHMENT 2 (E.G.
CLAMSHELL ROTATION, CRUSHER ROTATION)
REMARK
If installing 2nd attachment line as a field kit, ask distributor to change monitor setting to allow 2 attachments.
The switch on left lever is a roller proportional control switch. Rolling the switch up produces rotation in one di-
rection, rolling down produces rotation in the opposite direction. Slight movement 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/P or
ATT/E for the attachment mode, follow the instructions, see
“WHEN USING GENERAL ATTACHMENTS SUCH AS
CRUSHER”
LONG-TERM STORAGE
