Proportional control rolling switch.
The 2nd-line attachment proportional switch operates the 2nd
attachment circuit (e.g. clamshell rotation). The 2nd-line attach-
ment proportional switch 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 clamshell; full
movement of the roller will give faster movement of the clam-
shell.
REMARK
If installing 2nd attachment as a field kit, ask the distributor to
change monitor setting to allow 2 attachment mode.
