PAGE 30 — LT12DAB LIGHT TOWER • OPERATION MANUAL — REV. #0 (06/03/11)
MAINTENANCE
GENERAL INSPECTION
Prior to each use, the light tower 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
Check dust indicators on control panel daily or every 10
hours of operation. If light is ON, clean the air cleaner
element.
1. Unlatch 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.cm2,
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 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.
To restart after running out of fuel, operate the fuel primer
lever 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 6.
FLUSHING OUT RADIATOR AND CHANGING
COOLANT
1. Stop the engine and allow to cool. Tighten valve of the
corrosion resistor (if equipped).
2. Turn water filler cap slowly and remove it.
3. Prepare a container to catch the coolant, then open
drain plug of the radiator or heat exchanger and drain
plug of the engine, and drain the coolant.
4. After draining the coolant, close drain plugs and fill
with tap water.
5. When the water level is near the mouth of the water
filler, open drain plugs and start the engine, and run
at low idling. Keep the engine running at low idling and
flush the radiator for about 10 minutes.
6. Adjust the flow of the water flowing in and draining
out to ensure that the radiator is always full during the
WARNING
Allow engine to cool when flushing out
radiator. Flushing the radiator while hot will
damage radiator. In addition, the possibility
of hot coolant exists which can cause
severe burns.
