NOTICE
To the machine equipped with a breaker you need to install an accumulator whose model number
matches to that of the breaker manufacturer to the breaker piping . If breaker operation is performed
without having an accumulator installed, the service life of the machine will be reduced. Contact your
Komatsu distributor for further information regarding the breaker.
The accumulator (6) is installed to reduce the peak pressure in
the hydraulic circuit when the breaker is being used. Do not
touch it usually.
When inspecting the accumulator, see “METHOD FOR
CHECKING AND RELEASING NITROGEN GAS CHARGE
PRESSURE IN ACCUMULATOR (FOR BREAKER) (4-62)”.

WARNING
When operating attachment using rolling switch, lock the pedal with the lock pin to avoid accidental op-
eration.
When you operate attachment, the screen will switch to the screen including bird's eye view automati-
cally.
The 1st-line attachment proportional switch operates the 1st attachment circuit (e.g. crusher).
The 1st-line attachment proportional switch is a roller propor-
tional control switch. Rolling the switch up produces movement
of the attachment, rolling down produces opposite movement.
Slight movement of the roller will give slight movement of the
attachment; full movement of the roller will give faster move-
ment of the attachment.
2ND-LINE ATTACHMENT PROPORTIONAL SWITCH
(if equipped)
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.
