1.2 BATTERY
The tractors are equipped with a 12-volt battery with a
minimum cold cranking ability of 520-ampare at -18°C
(0°F). The battery is located under the hood in front of
the radiator. The battery connections must be tight and
free of corrosion. If necessary, wash the battery’s outside surface and terminals with a solution of baking
soda and water, making sure the solution does not get
inside the battery. After cleaning, wash the battery with
clean water, then apply a small amount of petroleum
jelly to the terminals to prevent corrosion. A good battery charge must be maintained in freezing
temperatures. If the battery is allowed to become discharged or run down, the electrolyte will become weak
and possibly freeze. This can result in damage to the
case. If the water must be added, use distilled water.
Add the water just before using the tractor. This ensures that the water will mix with the electrolyte during
the charging process, preventing the water from
freezing.

1.3 STARTING SYSTEM
When the main key switch is turned to the PREHEAT
position, the terminal AM is connected to the terminal
ON and GL. The glow plugs become red-hot, and the
preheat indicator lamp also lights on while preheating.
When the main switch is turned to the START position
with the safety switch on, the terminal AM is connected
to the terminal ON and ST.
Consequently battery current flows to the starter motor
and start the engine.
The main key switch automatically returns to the ON
position, the terminal AM is connected only to the terminal ACC and ON, thereby causing the starting circuit
to be opened, stopping the starter motor.
When the main key switch turned from the ON position
to the OFF position, the engine stop solenoid moves
the fuel injection pump control rack to the “NO FUEL”
position and stop the engine.

ELECTRIC SYSTEM
The charging system supplies electric power to various electrical devices and also charges the battery
while the engine runs.

1.5 LIGHTING SYSTEM
196WA03A
The lighting system consists of combination switch, hazard warning switch, flasher unit, stop lamp relay, stop
switch, head lights, turn signal lamps, tail lamps and stop lamps.
A . COMBINA TION SWITCH
The light switch is located on the left-hand side of the
dash.
The three position of the light switch are;
OFF
Taillight/Headlight (low-beam)
Headlights (high beam)
When the switch is in the “Headlights (high beam)”
position, the blue indicator will light.

B. HAZARD W ARNING SWITCH
The hazard light switch is a push-pull type switch located on the left-hand side of the dash below of the
main light switch. The two positions of the hazard light
switch are;
OFF(Push)
ON (Pull)
When the hazard light switch is in the “ON” position,
the turn signal symbol located in combination meter
will illuminate green and flash.
Important ; The hazard lights can be activated with the
key switch in the “OFF” position.
C. FLASHER UNIT
The flasher unit controls the flashing of the hazard
lights. This flasher unit is located under the combination meter.
Control the blinking time of the hazard flasher lamp.

D. ST OP AND TAIL LIGHTING COMPONENTS
a. Stop Relay
Relays monitor the current in a circuit. If current is
present, the relay activates a single pole, double throw
switch, causing it to flip over to its other position. The
relays are located under the combination meter.

b. Stop Switch
When the operator put the brake pedal, the load of the
pedal push the switch.
So, the contact is connected. This switch gives the stop
signal to the stop relay.
Then the stop relay will be energized.
c. Stop Lights (Only CK20-USA)
When the operator pushes the brake pedal, this lights
will be illuminated.
It gives the information of the stop to following vehicle.
Rated watt of the bulb is 12 V 21 W. Use only rated watt
of the bulb.
196WA08A
d. Tail Light (Only CK20-USA)
This lights only operates while the main light switch is
“Tail light/head light”. The lamp is mounted out side of
the rear combination lamps.
