OPERATING THE MACHINE
5-11
POWER MODE
One of three engine speed modes, E, P or H/P mode, can be
selected using power mode switch (1).
•
E (Economy) Mode
Even if the engine speed is reduced in the E mode, digging
force remains unchanged from that in the P mode. Although
production is reduced slightly more than in the P mode, the
fuel consumption and noise levels are reduced, allowing the
machine to operate most efficiently.
•
P (Power) Mode
Operate the machine in this mode when performing normal
work.
•
H/P (High Power) Mode
WARNING: In the H/P mode, the engine speed will
change quickly. To ensure safety, be sure to turn
power mode switch (1) to the P or E mode position be-
fore starting such works as loading the machine on or
off a trailer or lifting a load with the front attachment,
which may result in personal accidents if the engine
speed is suddenly changed.
When rolling in the arm while digging deep trenches for
example, more power may be required. In such cases, use
the H/P mode. The maximum power of the machine can be
utilized in this mode, increasing work efficiency when more
power is required than in the P mode.
The H/P mode is activated and the engine speed is in-
creased when the boom raise or the arm rolled-in operation
is made with the engine fast idle speed set at faster than
approx. 1650 min
-1
. In case of ZX180-3 class, it is faster than
approx. 1850 min
-1
.
NOTE: In the H/P mode, the engine speed changes depending
on load applied to the machine.
