MAINTENANCE & SERVICE

Removal of Soot and Heating Coil:

In the heating process, fuel residue in the form of soot 
deposits may develop between the heating coil pipe 
and block air flow which will affect burner combustion. 
When soot has been detected on visual observation, 
the soot on the coil must be washed off after following 
the coil removal steps (See Coil Removal page).

Rupture Disk:

If pressure from pump or thermal expansion should 
exceed safe limits, the rupture disk will burst allowing 
high pressure to be discharged through hose to ground. 
When the disk ruptures it will need to be replaced. 
Torque new rupture disk to 35 ft. lbs.

Fuel:

Diesel fuel must be clean, fresh, meet fuel specifica-
tions and be sourced from a known and reputable 
supplier. Clean, fresh and properly specified diesel 
fuel will provide assurances of maximum engine per-
formance and maximum fuel injection system longevity. 
The use of out-of-spec, dirty or questionable quality 
diesel fuel will result in engine performance and start 
ability problems as well as reductions in engine and 
fuel injection system life.
Use clean fuel oil that is not contaminated with water 
and debris. Replace fuel filter and drain tank every 100 
hours of operation.
All burner combustion system designs are geared 
toward the use of commercial grade diesel fuels. As 
such, use of fuels other than those designated "DF", 
i.e. DF2 (No. 2 Diesel Fuel), will result in degradation 
of performance and/or reduction in component life. It 
is understood that applications in certain situations re-
quire the use of fuels other than No. 2 diesel fuel.  See 
list of various fuels and comments pertaining to each.
Diesel engines are designed to operate on No. 2 diesel 
fuel. However, some geographical areas, change the 
diesel fuel supply depot to No. 1 diesel fuel in the winter 
months because of the col winter temperatures. No. 2 
diesel fuel provides maximum viscosity and lubricity 
but can have "waxing" problems at lower temperatures. 
We expressly recommend the use of No. 2 diesel fuels 
when temperatures are at or above 14°F. We recom-
mend that No. 1 diesel fuel be used when temperatures 
are at or below 14°F. The use of either EPA-high sulfur, 
off-highway diesel fuel or EPA-low sulfur, on-highway 
fuel for non-CARB certified engines is allowed. CARB 
certified engines must consume only EPA-low sulfur 
diesel fuels conforming to EPA 40 CFR 86-113-94.
We do not recommend the use of "heating oil", blended 
fuel/waste engine oil or low grade diesel fuel of any 
kind. The use of aviation fuels - JP4, JP5 or JP8 must 
be approved on an application basis and is not rec-
ommended for broad range commercial applications.

Fuel Control System:

This machine utilizes a fuel solenoid valve located on 
the fuel pump to control the flow of fuel to the combus-
tion chamber. The solenoid, which is normally closed, 
is activated by a flow switch when water flows through 
it. When the operator releases the trigger on the spray 
gun, the flow of water through the flow switch stops, 
turning off the electrical current to the fuel solenoid.
The solenoid then closes, shutting off the supply of 
fuel to the combustion chamber. Controlling the flow 
of fuel in this way gives an instantaneous burn-or-no-
burn situation, thereby eliminating high and low water 
temperatures and the combustion smoke normally 
associated with machines incorporating a spray gun. 
Periodic inspection, to insure that the fuel solenoid 
valve functions properly, is recommended. This can 
be done by operating the machine and checking to 
see that the burner is not firing when the spray gun is 
in the OFF position.

Fuel Quality / Storage

No. 1 and No. 2 diesel fuel degrades with time. No. 2 die-
sel 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 contaminated 
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 specifications 
listed above, fuel measured to have total insolubles > 
1 mg/100mg, organic material > 1 mg/100 ml or rust/
mineral matter > 2mg/ml should not be consumed in 
diesel engines.

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 
performance 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.
