SHUTDOWN:
1. Move the switch to the "Pump" 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.)

4. Turn off the water supply and trigger the gun momentarily to relieve trapped
pressure.
5. Disconnect and drain the high pressure hose, gun, and dual lance. Wipe the unit
clean and store in a non-freezing environment.
STORAGE & MAINTENANCE INSTRUCTIONS
SPECIFIC MAINTENANCE:
PUMP: Change the pump oil after the first 50 hours of operation. After initial change,
every 3 months or 250 hour intervals are recommended. If oil appears dirty or
milky, changes may be required in greater frequency. Use pump oil SAE20 or
30 and fill only to the center of the oil sight glass. DO NOT overfill.
QUICK COUPLERS: There are o-ring seals inside the couplers which will deteriorate.
To replace, simply install a replacement o-ring to correct the leak. (Additional
o-rings can be purchased from your dealer.)
NOZZLE: Water flow through the spray nozzle will erode the orifice, making it larger,
resulting in a pressure loss. Nozzles should be replaced whenever pressure
is less than 85% of the maximum. The frequency of replacement will depend
upon such variables as mineral content in the water and number of hours the
nozzle is used.
FUEL WATER SEPARATOR: The fuel filter has a built in water separator.
Occasionally the water has to be drained from the separator. Follow the procedures
listed below:
1. Check the collection bowl daily.
2. Ensure the unit is off and place an oil catch basin under the fuel
cartridge.
3. Loosen the drain plug to allow the fuel/water contaminents to flow into
the catch basin.
4. Retighten the drain plug when completed.
5. Dispose of drainage according to environmental regulations in your
area.
BURNER AIR ADJUSTMENT: The air shutter has been factory preset for proper
operation between sea level and 2000 feet elevation at standard conditions (60°F
ambient water and air temperatures). To assure maximum combustion efficiency
at colder temperatures and higher altitudes, it will be necessary to adjust the air
supply to the combustion chamber. A smoke spot test is recommended during
any air shutter adjustment. This will aid in maximizing the burner efficiency and
avoid the inefficient operation and excessive
sooting of the combustion chamber.
1. The machine must be running and the burner on.
2. Take a smoke spot test to determine if more or less air is required for
proper combustion.
a.
If the test is greater than a #3 smoke, turn the shutter arm
counterclockwise to increase the air flow into the combustion
chamber.
b.
If the test is yellowish in color, turn the shutter arm clockwise to
decrease the air flow into the combustion chamber.
3. Hold onto the air shutter adjusting arm and loosen the locking nut.
Move the shutter in 1/8" increments and retighten the locking nut after
each 1/8" movement.
4. Trigger the gun on and off slowly to make sure there is proper ignition.
Slight or no puffing on the ignition, and a smoke spot test of 0-3 is
good.
5. Repeat steps 2 and 3 until step 4 is attained.
LEAKS: Promptly eliminate any leaks found in the pumping system by removing
suspect parts, applying thread sealant to the threads and reinstalling.
NOTE: If using teflon tape, be certain no tape gets inside any plumbing to prevent
the possibility of a plugged spray nozzle.
