AISS LOW switch is used to switch the AISS functions.
AISS (Automatic Idling Setting System) adjusts the low idle
speed automatically depending on the engine coolant tempera-
ture and operating situations.
(A) AISS LOW switch ON
Use this switch position when fine start control is needed such
as when putting the machine into the garage.
The low idle speed is fixed to a rather low level.
REMARK
When the automatic warm-up is turned on, this switch position
stops it, and set a low idle speed to a rather low level.
(B) AISS LOW switch OFF
Use this switch position for the normal operation.
AISS function is actuated to produce the states described below.
• When the engine coolant temperature is low, this switch position automatically sets the idle speed to a high-
er level. (Automatic warm-up function)
• When the parking brake or retarder brake is applied, the idle speed is automatically set to a rather low level
in order to reduce fuel consumption when the machine is stopped.
REMARK
While the automatic warm-up is turned on, the idle speed is not set low even if the parking brake or retarder
brake is applied.
FRONT BRAKE OFF SWITCH

WARNING
Turn the front brake off switch to the position (A) to drive the machine slowly with a safe speed on the
frozen road, snow road, and slippery road.
You can change the braking method of the brake according to
the road condition with the front brake off switch.
Set the front brake to be disabled by turning off the front brake
off switch since the machine may go into a skid when the front
brake is applied on the soft road surface.
Set it to the position (B) usually.
Position (A)
The front brake off function is actuated.
Only the rear brake is applied when depressing the brake ped-
al.
Position (B)
The rear brake and front brake are applied when depressing the brake pedal.
REMARK
When the secondary brake is actuated, the front brake off switch is ignored. The front brake, rear brake, and
parking brake are applied.
