HANDLE MACHINE READY FOR INSTALLATION OF ATTACHMENT
This accumulator is installed to reduce the peak pressure in the
hydraulic circuit when the breaker is used. Do not touch it usu-
ally.
When inspecting the accumulator, see "METHOD FOR
CHECKING AND RELEASING NITROGEN GAS CHARGE
PRESSURE IN ACCUMULATOR (FOR BREAKER) (4-70)".
ATTACHMENT 1 PROPORTIONAL CONTROL SWITCH
Lock the pedal with the lock pin in order to prevent the attachment from moving incidentally when oper-
ating the attachment by using the rolling switch.
The attachment 1 proportional control switch is a roller propor-
tional control switch.
This switch actuates the attachment 1 proportional circuit (e.g.
the crusher).
Rolling up the switch makes the attachment move. Rolling
down the switch makes the attachment move in an opposite di-
rection.
Operate the roller slightly, and the attachment moves slightly.
Operate the roller fully, and the attachment moves quickly.
ATTACHMENT 2 PROPORTIONAL CONTROL SWITCH
(if equipped)
The attachment 2 proportional control switch is a roller propor-
tional control switch.
This switch actuates the attachment 2 proportional circuit (e.g.
rotating the clamshell).
Rolling up the switch generates the attachment movement in
one direction. Rolling down the switch generates the attach-
ment movement in an opposite direction.
Operate the roller slightly, and the clamshell moves slightly. Op-
erate the roller fully, and the clamshell moves quickly.
REMARK
Ask your Komatsu distributor to have the monitor setting
changed so that two attachments are available if the attach-
ment 2 system is to be equipped as a field kit.
BREAKER MODE SWITCH
Lock the pedal with the lock pin in order to prevent the breaker from moving incidentally when operat-
ing the breaker by using the breaker mode switch.
