General Inspection
Prior to each use, the generating set should be cleaned and
inspected for deficiencies. Check for loose, missing or damaged
nuts, bolts or other fasteners. Also check for fuel or oil leaks.
Air Cleaner
Every
50 hours
: Check dust indicators on control panel. If light is
ON, clean the air cleaner element.
1. Un-latch the holding clips and take out the air cleaner
element.
2. Clean the inside of the body and cover using a damp cloth.
3. Blow dry with compressed air (0.69Mpa {7kgf.cm
2
,
99.4 PSI} maximum) against the side of the element along
the pleats. Then blow dry against outside along the pleats,
then against inside again.
4. Remove one seal each time the element is cleaned.
5. Replace the outer element after cleaning it 6 times or after
one year. Replace the outer element if indicator is red even
after cleaning it.
6. If seal washer is damaged or the threads of wing nut are
damaged, replace.
7. Remove evacuator valve and clean it with compressed air.
Reinstall.
Fuel Addition
Add diesel fuel (the grade may vary according to season and
locations). Always pour through the mesh filter.
Removing Water from the Tank
After prolonged use, water and other impurities accumulate in
the bottom of the tank. Occasionally remove the drain cock and
drain the contents. During cold weather, the greater the empty
volume inside the tank, the easier it is for water to condense.
This can be reduced by always keeping the tank as full as
possible.
Air Removal
If air enters the fuel injection system of a diesel engine, starting
becomes impossible. After running out of fuel, or after
disassembling the fuel system, bleed the system according to
the following procedure.
To restart after running out of fuel, squeeze the fuel primer bulb
to pump fuel into the engine. This unit is equipped with an
automatic air bleeding system.
Service Daily
If engine is operating in very dusty and dry grass conditions, a
clogged air cleaner will result in high fuel consumption, loss of
power and excessive carbon buildup in the combustion chamber.
Cleaning the Fuel Strainer
Clean the fuel strainer if it contains dust or water. Remove dust or
water in the strainer cap and wash it in diesel. Securely fasten
the fuel strainer cap so that fuel will not leak. Check the fuel
strainer every 200 hours of operation or once a month.
Check Oil Level
Check the crankcase oil level prior to each use, or when the fuel
tank is filled. Insufficient oil may cause severe damage to the
engine. Make sure the generator is level. The oil level must be
between the two notches on the dipstick as shown in Figure 14.
