Maintenance
Fuel Quality / Storage
No. 1 and No. 2 diesel fuel degrades with time. No. 2
diesel fuel has a storage life of approximately one (1)
year. No. 1 diesel fuel has a maximum storage life of
two (2) years. Further, storage of diesel fuel in contam-
inated storage tanks can lead to excessive impurities
within the stored fuel. As such, aged or contaminated
diesel fuel should not be used. Aside from the specifi-
cations listed above, fuel measured to have total insol-
ubles > 1 mg/100mg, organic material > 1 mg/100 ml or
rust/mineral matter > 2mg/ml should not be consumed
in diesel engines.
Component failure that can be directly attributed to the
use of fuels other than those recommended cannot be
covered under warranty.
Fuel Pressure Adjustment:
To control water temperature, adjust fuel pressure by
turning the regulating pressure adjusting screw
clockwise to increase, counterclockwise to decrease.
Do not exceed 200 psi.
NOTE: When changing fuel pump, a bypass plug
must be installed in return port or fuel pump will not
prime.
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.
LANDA Sure Fire Oil Burner
Burner 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.
Fuel Grade/Type Comments
No. 2 Diesel Fuel (DF2)
No. 2-DS15
Recommended fuel type
for normal ambient
operation
No. 1 Diesel Fuel (DF1)
No. 1-D S15
Recommended fuel type
for cold weather operation
in ambients which would
result in DF2 “waxing”. No
degradation in perfor-
mance or engine/
component life.
JP 4 Turbine Fuel Not recommended. JP4
should be used only in
emergency situations. JP
4 severely reduces engine
life and potential power
due to the lack of lubricity
as compared to DF2.
Fuel Grade/Type Comments
JP 8 Turbine Fuel 5-12% reduction in power
and up to 30% reduction in
fuel system component
and cylinder life.
JP 5 Turbine Fuel Refer to JP 8
DF A Arctic Acceptable fuel for use in
sub-zero ambients only.
