MAINTENANCE AND INSPECTION OF CARRIER

2. 

◆

 Inspection and Maintenance of the 
inside of fuel tank and fuel strainer

 

★

Fuel is highly inflammable. 

Turn the starter switch OFF and avoid any fire source while the fuel sys-
tem is being maintained.

 

★

Wipe up spilled fuel thoroughly to avoid an accidental fire.

Clean the inside of fuel tank if the engine is 
hard to be started and/or it gives insufficient 
driving power due to poor supply of fuel.

Drain plug

WARNING

1 

Place a container under the drain plug to 
catch the drain oil.

2 

Remove the drain plug to drain the fuel.

3 

Wash up inside of the tank with non-
flammable wash oil.

4 

Check the O-ring of the drain plug 
to tighten it. 

 

Replace the O-ring with a new one when it is 
damaged.

5 

Bleed air out of the fuel system and 
check for fuel leakage.
