REVERSE TRAVEL SPEED INDICATOR
This indicator (5) displays the travel speed when traveling in reverse.
It is possible to choose the reverse travel speed in five stages according to the nature of the work without changing
the forward travel speed. This means that the reverse travel speed can be obtained simply by shifting the direc-
tional lever. There is no need to shift gear.
If it is desired to raise the efficiency of dozing work, make the reverse travel speed faster.
When traveling in reverse on rough ground surfaces or when carrying out pushing-up work, make the reverse
travel speed slower.
q
There are five settings (A) - (E) for the reverse travel
speed.
The closer the setting is to (A), the slower the reverse
travel speed is in comparison with the forward travel
speed; the closer the setting is to (E), the faster the reverse
travel speed is in comparison with the forward travel
speed.
q
When the starting switch is turned from the OFF position to
the ON position, the travel speed is set by default to posi-
tion (C).
q
Position (B) sets to the same speed as the forward travel
speed.
q
The reverse travel speed is set by turning reverse travel
speed switch (8) to the left or right.
The more it is turned to the right, the faster the set travel
speed becomes.
The more it is turned to the left, the slower the set travel
speed becomes.
