Working mode
through working mode switch, one of the following 4
modes namely H
、
S
、
L
、
B can be chosen for work.
a)
Mode S (standard excavating mode)
It can save fuel consumption best and should be adopted in
normal work. When it works, mode S indicator shines.
b)
Mode L (weak excavating mode and mode of leveling up
ground )
In this mode, engine speed may be reduced, but excavation
force remains the same with mode S. although the output
is little less than that of mode S, but the fuel consumption
and noise have been reduced for the machine to do some
light-duty work such as leveling up ground. In this mode,
indicator of mode L shines.
c)
Mode H (strong excavating mode)
It is suitable for excavating hard ground in short time. It can give full play the max. power of engine
to enhance the working efficiency. When this mode works, indicator for mode H is on.
d)
Mode B (knapping hammer mode)
