Shutdown - Xtream HW2765HAD Operation Manual

1. Prepare detergent solution according to label directions. Never pump
acids, alkaline, abrasive fluids or solvents through the unit.
2. Adjust the amount of detergent desired by locating the adjustment
knob at the end of the clear vinyl hose. Turn the knob completely
counterclockwise to set at maximum siphon rate.
3. Fully immerse the detergent strainer into the detergent solution.
4. With the trigger gun locked in the "OFF" position, securely quick-
connect the detergent spray nozzle (#65 40° BLACK) into the end of
the wand.
5. To apply solution; unlock the trigger gun and squeeze the trigger. In
a few moments a detergent/water mixture will exit the nozzle. Start
spraying the lower portion of the surface being cleaned and move up,
using long overlapping strokes. Applying from the bottom up helps
avoid streaking. Allow to soak briefly. (Avoid working on hot surfaces
or in direct sunlight to minimize the chances of the detergent drying,
which may result in damaging painted surfaces.) Be certain to rinse a
small section at a time.
6. To rinse; lock the trigger gun in the "OFF" position, securely quick-
connect the desired high pressure nozzle into the end of the wand.
Unlock the trigger gun and spray. It will take about 30 seconds to
purge all detergent from the line. For best rinsing results, start at the
top and work down.
7. Siphon a gallon of water through the low pressure detergent injection
system after each use. This prevents the possibility of corrosion or
detergent residue causing mechanical problems during the next use.

SHUTDOWN

1. Move the Burner Switch to the OFF position.
2. Squeeze the trigger and discharge the water for a period of three
minutes to cool the heat exchanger and high pressure hose.
(Insufficient cool down period of the high pressure hose will cause
excessive wear and eventual rupturing of the hose.)
3. DO NOT close the choke to stop the engine. Backfire or engine
damage may occur. Turn the engine "OFF" as directed in the engine
manual.
4. Close the engine fuel shut-off valve.
5. Turn the water supply "OFF".
6. Pointing the gun in a safe direction, trigger the gun momentarily to
relieve trapped pressure.
7. Disconnect and drain the nozzle assembly, gun, wand and hoses.
8. Store complete assembly in a non-freezing environment.
