Operating the Machine
H/P (HIGH POWER) MODE
NOTE: With both the H/P and E modes turned on, the
digging power increases while achieving low fuel
Use H/P mode when extra horse power is needed for
rolling in the arm in excavation work. The H/P mode is
effective when the dig mode is selected as the work
mode. H/P mode can also be used with the E mode
The H/P mode will be activated, automatically increasing
the engine speed when:
H/P mode switch (A) is pushed down.
Engine speed is set to 1600 rpm or higher.
Arm roll-in is operated.
A load heavier than a specified amount is applied.
Push down H/P mode switch (A). The switch will stay
down and H/P mode indicator will light. Push the H/P
mode switch again. The switch will return to original
position and will deactivate the H/P mode.
The engine is in standard mode when no switches are
pushed down and no indicator lights are on.
