Work Mode - Hitachi Zaxis 850LC-3 Operator's Manual

WORK MODE

Five work modes can be selected for most appropriate front
and swing speeds for the work to be performed.
When the engine is started, the digging mode is automatically
set. Each time work mode switch is pressed, the four following
modes are selected alternately.
• Digging Mode
• Breaker 1
• Breaker 2
• Breaker 3
• Breaker 4
The selected work mode is indicated by attachment mode
indicator (2) of basic screen (1). Select the work mode corre-
sponding to the work in which the machine is engaged while
referring to the table below.
Digging Mode
Breaker 1 Mode ✽ 1 (Initial Set-
ting Flow Rate 260L/min)
Breaker 2 Mode ✽ 1 (Initial Set-
ting Flow Rate 300L/min)
Breaker 3 Mode ✽ 1 (Initial Set-
ting Flow Rate 320L/min)
Breaker 4 Mode ✽ 1 (Initial Set-
ting Flow Rate 350L/min)
✽ 1 When using hydraulic crusher, select the breaker mode 1, 2,
3 or 4 when the flow rate of the crusher corresponds to the
breaker mode 1, 2, 3 or 4.
NOTE: Four work modes shown above are designated as the
standard specifications. Up to four attachment modes
other than the digging mode can be designated. Con-
sult your nearest Hitachi dealer for adding or changing
the designation of the attachment modes.
As for the machine equipped with the flow combined pip-
ing, when the flow combining valve is set to two pump
combined, flow rate becomes the flow rate of selected
breaker mode + pump 1.
When using hydraulic breaker or crusher, if required setting
flow rate is insufficient, see your nearest authorized dealer
for correct information.
As for the machine equipped with the flow combined pip-
ing, switch the flow combining valve to the suitable position
for the usage. (Refer to the flow combining valve operation
of Chapter 13 in detail.)
