6. Open the antifreeze tank valve. This tank must be full of an antifreeze mixture
with strength of no less than a 50/50 mix.
7. Remove the gun or any jetting nozzle from end of the hose and unreel 10 feet
of hose.
8. Ensure the unit starts in dump (radio – nothing to do, manual – put pressure
selector to dump)
9. Hold the open-ended hose away from the body pointing it to the ground and
away from any by-standers.
10. Start the engine and run at idle speed. As shown as engine runs, switch water
to pressure. Water will come from the end of the high-pressure hose. (It may
be necessary to bleed the pump if water flow is very slow)
11. After a minute or two the antifreeze mixture will start to come out of the high-
pressure hose. IMMEDIATELY SWITCH OFF THE ENGINE.
12. Place the end of the high-pressure hose into the antifreeze tank. If the hose is
clean you may remove the strainer in the tank lid to make it easier.
13. Restart the engine and allow the antifreeze to circulate. Briefly (about 2
seconds) move the selector valve from HIGH-PRESSURE to DUMP and back
to HIGH-PRESSURE (use water on button for radio system). Briefly (about 4
seconds) put the ‘jump jet’ valve into the ‘On’ position and then return to the
‘Off’ position. See picture below.
14. Stop the engine.
15. Manually rewind the hose back on the reel and lock in position.
4.11.2. To De-Antifreeze the Machine
1. Shut the anti-freeze valve.
2. Shut the drain valve.
3. Open the tank isolation valve.
4. The handle for the 3-way ball valve should be in the horizontal position (as shown).
5. Re-fill the water storage tank.
6. Put jump jet valve into the ‘off’ position.
7. Place the high-pressure hose (NO NOZZLE ATTACHED!) into the antifreeze tank.
8. Start the engine with the selector on ‘HIGH-PRESSURE’. (If on radio put water on
as soon as the engine starts.)
9. Pump out the antifreeze solution from the high-pressure hose back into the
antifreeze tank.
10. As the antifreeze mix reaches the top of the tank turn engine off. (Regularly check
the strength of the antifreeze mixture ensuring it is at least a 50/50 mix)
11. Place the jump jet valve in the on position.
