PERIODIC MAINTENANCE

PROCEDURES

WARNING

Exposure Hazard.

Always wear personal protective

equipment when performing periodic

maintenance procedures.

Daily Checks

Before you head out for the day, make

sure the Yanmar engine is in good

operating condition.

NOTICE

It is important to perform the daily checks

as listed in this Operation Manual. Periodic

maintenance prevents unexpected

downtime, reduces the number of

accidents due to poor engine performance

and helps extend the life of the engine.

Make sure you check the following items.

Visual Checks

1. Check for engine oil leaks.

2. Check for fuel leaks.

WARNING

Piercing Hazard.

Avoid skin contact with the high-pressure

diesel fuel spray caused by a fuel system

leak, such as a broken fuel injection line.

High-pressure fuel can penetrate your

skin and result in serious injury. If you are

exposed to high-pressure fuel spray,

obtain prompt medical treatment.

Never check for a fuel leak with your

hands.

Always use a piece of wood or

cardboard. Have your authorized

Yanmar Marine dealer or distributor

repair any damage.

3. Check for engine coolant leaks.

4. Check for damaged or missing parts.

5. Check for loose, missing or damaged

fasteners.

6. Check the electrical harnesses for

cracks, abrasions, and damaged or

corroded connectors.

7. Check hoses for cracks, abrasions, and

damaged, loose or corroded clamps.

8. Check the fuel filter/water separator for

presence of water and contaminants. If

you find any water or contaminants,

drain the fuel filter/water separator. See

Draining Fuel Filter/Water Separator on

page 69. If you have to drain the fuel

filter/water separator frequently, drain

the fuel tank and check for the

presence of water in your fuel supply.

See Draining the Fuel Tank on page 63.

NOTICE

If any problem is noted during the visual

check, the necessary corrective action

should be taken before operating the

engine.

Check Diesel Fuel, Engine Oil and

Engine Coolant Levels

Follow the procedures in Diesel Fuel on

page 32 , Engine Oil on page 37 and

Engine Coolant on page 41 to check these

levels.
