LT6KV LIGHT TOWER • OPERATION MANUAL — REV. 2 (07/08/16) — PAGE 45
CHECK CABLE WEAR
The wire rope (cable) that raises and extends the mast is
a very important part of the light tower.
SERVICING THE MAST RAISE/LOWER CABLE SYSTEM:
To replace any components in the
mast raise/lower
cable
system, use the following steps:
1. Lower the mast to the stowed vertical resting position.
2. Inspect the cable clamps, pulleys, and other components
for worn or damaged parts.
3. Disconnect the cable from the wedge or 7/16" hex nut
on the electric hoist drim and remove from the mast
pulleys. Detach the cable from the electric winch as
necessary.
4. Replace the pulleys and the cables as needed.
5. Rethread the cable through the pulley and reattach the
cable to the electric hoist drum.
6. Raise and lower the mast several times to verify correct
operation.
DANGER
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.
MAINTENANCE
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. Fill radiator with water using a 50/50 coolant/water
ratio mixture of 50% coolant concentrate and 50%
demineralized water.
14. Fill radiator to the top of the radiator filler neck, then
tighten radiator cap.
