maintenance
1. Stop the engine and allow it 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
flushing operation. While flushing water through the
system, make sure the water inlet hose does not come
out of the radiator filler port.
7. After flushing, stop the engine, open drain plug and
drain the water, then close drain plugs.
8. After draining the water, flush the system with a flushing
agent. See instructions on flushing agent label.
9. After flushing, open drain plugs and drain out all the
water, then close drain plugs and add tap water so the
water level is near the mouth of the water filler.
10. When the water level is near the mouth of the water
filler, open drain plugs and start the engine, run at low
idling and continue to flush the system until clean water
comes out. Adjust the flow of the water flowing in and
draining out to ensure the radiator is always full during
the flushing operation.
11. When clean water comes out, stop the engine, drain
all the water, then close drain plugs.
12. Remove the corrosion resistor (if equipped) and open
valve.
13. Supply water until it flows over the water filler.
14. Drain the water inside reserve tank, clean the inside of
the reserve tank, then fill with coolant/water mixture to
between the full and low lines.
15. Stop the engine, wait for 3 minutes, add tap water until
the water level reaches near the water filler port, then
tighten the radiator cap.
CHeCK CaBLe WeaR
The wire rope (cable) that raises and extends the mast is
a very important part of the light tower. There is one cable/
hand winch system, located on the tongue of the trailer, that
raises and extends the light tower mast. There is a second
cable/hand winch system located on the mast that serves
to raise and lower the two extendable sections of the mast.
seRvICIng THe masT RaIse/LOWeR CaBLe sYsTem:
To replace any components in the mast raise/lower cable
system (Figure 29), use the following steps:
Figure 29. Mast Raise/Lower Cable System
1. Lower the mast to the horizontal resting position.
2. Inspect the cable clamps, pulleys, and other components
for worn or damaged parts.
3. Disconnect the cable from the ball socket pin and
remove from the mast pulley and cable sheave. Detach
the cable from the hand winch as necessary.
4. Replace the pulley and the cable as needed.

Wire rope (cable) will fail if it is worn, frayed, misused,
crushed, kinked or damaged in any way. ALWAYS
check the cables and pulleys for any abnormalities
before use.
dO nOT use it if there is even the slightest cause for
concern and replace any damaged cables or pulleys
immediately.
