element regularly.
CLEANING AND REPLACING THE FUEL FILTER
The fuel filter also has to be cleaned regularly to insure maximum engine output. Clean fuel filter every six months or 500 hours of operation. Replace fuel filter every year or 1000 hours of operation.
1.Drain the fuel oil from the fuel tank.
2.Loosen the nuts of the fuel cock and pull out the filter from the fuel tank filler port. Wash the filter thoroughly with diesel fuel.
CLEANING THE SPARK ARRESTER
If the engine has been running, the
muffler and the spark arrester will be very hot. Allow these to cool before proceeding.
Remove the lock nut, end cap and diffuser discs and clean off the carbon deposits. Clean spark arrester every three months or 100 hours of operation (or earlier if dirty).

Figure 25 - Spark Arrester
A clogged spark arrester hinders
the flow of exhaust gas. This reduces engine output, increases fuel con- sumption and makes starting difficult. Make sure you clean your spark arrester regularly.
TIGHTEN CYLINDER HEAD BOLTS
Tightening the cylinder head bolts requires a special tool. Don’t try it yourself. Consult your Yanmar dealer.
CHECKING THE INJECTION NOZZLE, INJECTION PUMP, ETC.
•Adjusting the valve head clearance for the intake and exhaust valves.
•Lapping of intake and exhaust valves.
•Replacing piston ring.
All these require special tools and skills. Consult your Yanmar dealer.
Do not perform the injection nozzle
test near an open fire or any other kind of fire. The fuel spray may ignite. Do not expose bare skin to the fuel spray. The fuel may penetrate the skin and cause injury to the body. Always keep your body away from the nozzle.
CHECKING AND REPLENISHING BATTERY FLUID AND CHARGING THE BATTERY
Battery fluid will be lost through continu- ous charging and discharging.
The battery electrolyte
contains sulfuric acid. Protect your eyes, skin, and clothing. In case of contact, flush thoroughly with water and get prompt medical attention, especially if your eyes are affected.
Batteries generate hydrogen gas,
which can be highly explosive. Do not smoke or allow flames or sparks near the battery, especially during charging.
NOTE: Much more fluid is lost during summer than in winter.
Before starting, check for physical damage to the battery and also the electrolyte levels, and replenish with distilled water up to the upper mark if necessary. When actual damage is discovered, replace the battery. Check battery fluid monthly.
Before charging, remove the cap
from each cell of the battery. Charge the battery in a place where there is plenty of ventilation. Discontinue charging if the electrolyte temperature exceeds 45° C (117° F).
Do not charge the battery with the
battery cable still connected. The diodes will be damaged by the high voltage.
Connect the (+) lead of the charger
to the (+) terminal of the battery, and the
Storage
Remove all fuel from fuel tank
before storing generator. Store fuel in approved container. Store fuel in a
The muffler becomes very hot
during operation. The muffler remains hot for a while after shutdown. Let engine cool before storing.
IMPORTANT: Keep generator level while in storage. Never store generator upside down or standing on end.
Cover and store generator in a clean, dry place. Do not expose generator to extreme high or low temperatures during storage.
