Air bleed plug
(3) Air-bleeding from clutch line
(MEC models only)

If there are air bubbles in the hydraulic clutch line,
the main clutch may not be released completely.
1. Stop engine and apply parking brake. Fill the
brake oil tank with new oil sufficiently.
For oil specification, see page 5-15.
2. Carry out air-bleeding work from clutch release
cylinder first and clutch master cylinder later.
3. Loosen the air-bleed plug and press and hold
the clutch pedal down slowly up to full stroke.
4. Fasten the plug slightly and then release the
clutch pedal. Repeat procedure 3~4 for several
times.
5. If there is no bubbles coming out through the air
bleed plug, check if the main clutch is completely
disengaged. Check the tightening torque of the
air-bleed plug.
(2) Air-bleeding from brake lines
1. As the brake system of this tractor is separated
into left and right brake, the air bleeding must be
carried out separately.
2. Stop engine and apply parking brake. Open the
bonnet and fill the brake oil tank with new oil
sufficiently. For oil specification, see page 5-15.
3. Release the left/right connecting pin of the brake
pedals.
4. Loosen the air-bleed plug, and press and hold a
brake pedal down slowly up to full stroke.
5. Fasten the plug slightly, and then release the
brake pedal. Repeat procedure 4~5 for several
times.
6. Check the brake oil level frequently during the
air bleeding work.
7. If there is no bubbles coming out through the air
bleed plug, check if the brake pedal pressure
and equalization is normal. Check the tightening
torque of the air-bleed plug.
