MAINTENANCE
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.
CHANGING OIL
1.Make sure the oil is cool before changing.
2.Set a container directly under the drain plug of the oil pan. Loosen the drain plug slowly.
3.Check the drained oil for excessive metal particles or foreign material. Contact the distributor if there is metal particles or foreign material.
4.Using a filter wrench, turn filter cartridge to the left to remove it. If the filter cartridge is filled with a large amount of oil, wait 10 minutes or so before removing. Make sure there is no old gasket stuck on the filter holder.
5.Tighten drain plug. Clean the filter holder, fill the new filter cartridge with clean engine oil, coat the packing and thread of the new filter cartridge with engine oil, then install it to the filter holder.Tighten until the gasket surface contacts the seal surface of the filter holder, then tighten it a further 3/4 to 1 turn.
6.Add engine oil through oil fi ller until the oil level is between the H and L marks on the dipstick.
7.Run the engine at idling for a short time, then stop the engine. Recheck the oil level and fill as necessary.
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.
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.
