CAUTION
Be certain the hoses and spray gun are not attached to the pump during application
of pump saver or use of the blowout tool. Having a hose attached greatly reduces the
amount of water/debris removed from the pump and coil.
SHUTTING THE UNIT DOWN
1. Move the burner switch to the “OFF” position.
2. Squeeze the trigger and discharge the water for three minutes to cool the heat
exchanger and high pressure hose. Insucient cool-down periods for the high
pressure hose will cause excessive wear and eventual rupture of the hose.
3. Do not close the choke to stop the engine. Backfire or engine damage may occur.
4. Move the engine key switch to the OFF position.
5. Turn o the water supply and pull the trigger of the gun to relieve trapped pressure.
Disconnect and drain the high pressure hose, gun, and lance. Wipe the unit clean and
store in a non-freezing environment.
SHUTTING DOWN & STORAGE
STORAGE & WINTERIZING
When storing the unit for winter, it is important to ensure it is stored in the right
environment. Ensure the storage area stays above freezing during cold weather, and try
to limit the amount of dust gathered on the unit via a cover.
You will need to ensure that the fuel is drained from the engine prior to storage. For the
steps required to do this, see the engine user manual.
Once the unit has been stored and the gasoline has been drained, the last thing to do is
to winterize your pump. This can be done in one of two ways:
• BE “Pump Saver” Solution (P/N: 85.490.046). This is an anti-freeze solution that
is used before storing the unit. It coats to inside of the pump to ensure that any
residual water doesn’t freeze. To use BE Pump Saver, follow the instructions written
on the bottle. Water freezing in the pump will damage seals and other internal parts.
Freezing damage is not covered by warranty.
• BE “Pump & Coil Blowout Tool” (P/N: 59.400.000). This tool utilizes compressed
air to forcefully remove any water left in the pump. One end of the tool attaches to
an air compressor, while the other attaches to the inlet of your water pump via an
adapter. Follow the instructions on the back of the packaging to use the Pump and
Coil Blowout Tool.
MAINTENANCE
SPECIFIC MAINTENANCE
ENGINE: The engine instructions that accompany your unit detail specific procedures
for maintenance of the engine. Following the engine manufacturer’s recommendations
will extend the engine’s life and ensure the best possible performance.
PUMP: Change the pump oil after the first 50 hours of operation. After the 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 SAE 30 non-detergent pump oil
and fill only to the center of the oil sight glass. DO NOT overfill.
NOZZLE: Water flow through the spray nozzle will erode the orifice over time, making it
larger. This will result in a reduction of pressure. 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. Every 3-6 months tends to be a standard interval for replacement.
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). In colder temperatures or higher altitudes, it
may be necessary to adjust the air supply to the combustion chamber. This adjustment
will maximize burner eciency and avoid inecient operation or excessive sooting
of the heat exchanger coil. A smoke spot test is recommended during any air shutter
and band adjustment. If you do not have the equipment to perform a smoke spot test,
follow the procedures listed below.
1. The machine must be running and the burner ON.
2. Loosen the Locking Screw (#3 at left) on the shutter.
3. Check for smoke from the heat exchanger exhaust. If smoke is not present, slowly
close the Air Shutter (#1 at left) by moving the dial counterclockwise to a lower
number. Continue moving the dial until smoke appears.
4. Record this setting.
5. Open Air Shutter (#1 at left) two increments. Example: If Air Shutter was set at 2,
move it to 4.
6. Slowly trigger the gun on and o. This will cause the burner to turn on and o. Look
for a smoke pu when the burner ignites.
7. Repeat steps 5 and 6 until you see a pu of smoke. Record the Air Shutter Setting.
8. The dierence between the recorded settings in steps 4 and 7 is the combustion
window. Set the dial 1/2 way between these settings.
