OPERATION
EXPLANATION OF COMPONENTS
FRONT BRAKE CUT-OFF SWITCH
WARNING
When traveling on icy roads, on snow, or on other slippery road surfaces, set the front brake cut-off switch to the ON position
and travel slowly at a safe speed.
If the front brake cut-off switch is set to the OFF position, it becomes dangerously difficult to control the steering when
traveling under the abovementioned conditions.
This switch (5) switches the braking method according to the road
surface conditions.
If the switch is pressed, the lamp lights up, the front brake cut
function is actuated, and the brakes are not applied to the front
wheels.
If the switch is pressed again, the lamp goes out and the front
brake cut function is canceled.
OFF position (Light is off.):
When the brake pedal is depressed, the brakes are applied to both
the front and rear wheels.
ON position (Light is on.):
When the brake pedal is depressed, the front brakes are not
applied. The brakes are applied only to the rear wheels.
When traveling at high speed, on a road surface that has been properly watered, set the front brake cut-off switch
to OFF position (lamp off), and normally use the retarder control lever to control the travel speed (retarder braking
is applied only to the rear wheels).
To control the machine whenever emergency action is needed, such as when the machine slips to the side or when
the machine has to be stopped suddenly, use the brake pedal to operate the brakes on the front wheels to give extra
braking force.
HAZARD LAMP SWITCH
This switch (6) flashes the left- and right-hand turn signal lamps.
When the switch is turned on, the turn signal pilot lamp flashes at
the same time. If the starting switch is OFF, the turn signal pilot
lamp does not flash.
