reStarting after adding 
fuel

bleeding air from the fuel SyStem

reStarting after adding fuel

1. Add fuel.

<TB285>

2. Turn the starter key to the ON position and 

hold it for about 10 to 15 seconds.

  The automatic air bleeder bleeds air from 

the fuel system.

<TB290>

2. Loosen the vent plug (5) of the main fuel 

filter (2).

3. Turn the starter key to the ON position and 

wait for the air to be bled from the vent 

plug (5).

4. Retighten the vent plug (5) when air 

bleeding is finished and fuel starts leaking 

out from around the vent plug (5). 

5. Turn and hold the starter key to the ON 

position for three minutes before turning it 

back to the OFF position.

Note:

 Air in the fuel system causes the 

engine to fail to start or to have other 

problems. Always bleed air when the fuel 

tank is emptied or when there is air in the 

fuel system.
