Burner Nozzle:
Keep the tip free of surface deposits by wiping it with a
clean, solvent saturated cloth, being careful not to plug
or enlarge the nozzle. For maximum efficiency, replace
the nozzle each season.
Air Adjustment:
The oil burner on this machine is preset for operation at
altitudes below 500 feet. If operated at higher altitudes,
it may be necessary to adjust the air band for a #1 or #2
smoke spot on the Bacharach scale.
To adjust, start machine and turn burner ON. Loosen
two locking screws found on the air band and close air
band until black smoke appears from burner exhaust
vent. Note air band position. Next, slowly open the air
band until white smoke just starts to appear. Turn air
band halfway back to the previously noted position.
Tighten locking screws.
For higher altitudes, the air band opening may need to
be increased; for lower altitude, the .air band may need
to be decreased.
For higher humidity, the air band opening may need to
be increased; for lower relative humidity, the .air band
may need to be decreased.
For higher ambient temperatures the air band opening
may need to be increased; for lower ambient tempera-
tures, the air band opening may need to be decreased.
Adjust to your operating location's environment
asneeded for best smoke spot and performance
compliant with local, state, and federal regulations.
CAUTION:
If white smoke appears from burner
exhaust vent during start-up or operation, discontinue
use and readjust air bands.
PRESSURE WASHER MAINTENANCE
ATTENTION:
Si de la fumée blanche s'échappe de
l'évacuation du brûleur pendant le démarrage ou le
fonctionnement, cesser d'utiliser et réajuster les
bandes d'air.
NOTE: If a flue is installed, have a professional
serviceman adjust your burner for a #1 or #2 smoke
spot on the Bacharach scale. If the desired position
cannot be obtained using only the air shutter, lock the
air shutter in as close a position as can be obtained,
then repeat the above procedure on the air band
setting.
Coil Removal:
Removal of coil because of freeze breakage, or to clean
soot from it can be done quickly and easily.
1. Disconnect hose from pump to inlet side of the coil.
2. Carefully disconnect the thermostat sensor making
sure you do not crimp the capillary tube.
3. Remove burner assembly from combustion
chamber.
4. Remove the 3-3/8" bolts from each side of coil and
tank assembly (these bolts are used to fasten tank
to chassis).
5. Remove fittings connected to the 1/2" pipe nipples
from inlet and discharge sides of coil.
6. Remove top tank wrap, bend back insulation tabs
and fold back blanket.
7. Remove bolts that hold down coil to bottom wrap.
8. Remove coil.
9. Replace or repair any insulation found to be torn
or broken.
