CHECKS BEFORE START20
A The travel speed automatically changes into first
speed (low speed) when the drive resistance
increases while traveling second speed (high speed).
Thereafter, when the resistance decreases, it returns
to second speed.
A If the tracks are clogged with sand or gravel while
working on soft ground, lift up the track with the help of
the boom, arm and bucket and dozer blade, and let the
track rotate to remove the sand and gravel.
A Do not push the dozer control lever into the float
position as this will cause the machine to
suddenly drop.
To avoid serious injury or death:
A Do not work under the machine in this
condition.

BWiper/Washer Switch
To engage the wiper, turn on the switch for the wiper when
the starter key is in the "RUN" position. A further push on
the switch will activate the washer system. Even when the
wiper switch is in the "OFF" position, the washer switch
functions if it is pressed.
A Do not activate the washer switch if the tank for the
cleaning fluid is empty; the pump can be damaged.
A Do not activate the wiper switch if the window is dry. In
this case, make sure that cleaning fluid is applied to
the pane before activating the wiper.
A In frosty conditions, make sure that the wiper blade is
not frozen to the glass before switching-on. The motor
can be damaged if the wiper system is used under
such conditions.
