Pressure Switch Resistance

1. Disconnect the pressure switch connector (1).

2. Connect  the  circuit  tester  pins  to  each  terminal  of  pressure

switch (2).

3. Start the engine and depress the clutch pedal.

4. Check the resistance at time when shuttle lever or GST lever is

shifted.

5. It  is  OK  if  the  resistance  comes  to  have  shown  in  the  table

below.

NOTE

• It is not necessary to adjust any kind of mode.

 CAUTION

• Be sure to depress the clutch pedal so that the tractor

should not move while shifting each lever.

Oil Temperature Sensor Resistance

1. Measure the resistance between the sensor terminals.

2. It is OK if the resistance value approximates to the value shown

in the table below.

3. If the exists a large difference, replace the sensor.

NOTE

• It is not necessary to adjust any kind of mode.

Proportional Reducing Valve Resistance

1. Measure the resistance between the valve terminals.

2. It  is  OK  if  the  resistance  comes  to  have  shown  in  the  table

below.

NOTE

• When replacing the proportional reducing valve be sure to

adjust the mode "F".
