OPERATION EXPLANATION OF COMPONENTS
SEAT HEATER SWITCH
This seat heater switch is used to warm the seat.
(a) OFF
Stops the seat heating.
(b) ON
Start the seat heating and the seat becomes warm.
MACHINE PUSH-UP SWITCH
Machine push-up switch is used to set the safety valve pres-
sure on the head side of the boom circuit to 2 stages.
(a) Low-pressure set
Since the bracing force of the boom is decreased, the machine
is less moved up during digging work and the operator can dig
smoothly.
Use this position for the general normal operation for ordinary
soil, soft rocks, blasted rocks, etc.
(b) High-pressure set
Since the bracing force of the boom is increased, the machine
can easily escape from soft ground.
QUICK COUPLER SWITCH
The switch (1) on the R.H. console and the switch (2) on the
L.H. work equipment control lever are the switches to operate
the quick coupler.
For details, see "HANDLE QUICK COUPLER (6-5)".
