Pump Control
Pressure Increasing System (continued)
L Mode
A Even though the one-touch digging force UP switch is pressed, the voltage is not output to the solenoid valve, and a
pressure increase is not obtained.
B Pressure raising is performed in H, S mode when travel pressure switch is ON. A pressure increase is obtained in travel
plus an attachment function.
F Mode
When F mode is set, voltage is output to the solenoid valve regardless of one-touch digging force UP, and results in
pressure raising condition.
Result
1
A pressure increase is obtained when the travel lever is moved (not displayed on the monitor).
2
There is a pressure increase when travel and an attachment function is called for, even though the digging force UP
switch is not pressed.
3
H,S,F mode: pressure increases during an attachment function. However, in H, S mode digging force UP switch must be
pressed. It is displayed on the monitor. In F mode, the pressure will always increase for improvement of lifting work ability.
It is not displayed on the monitor.
