15MaintenanceRemoval of Soot and Heating CoilIn the heating process, fuel residue in the form of sootdeposits may develop between the heating coil pipeand 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 followingthe coil removal steps (See Coil Removal).Rupture DiskIf pressure from pump or thermal expansion shouldexceed safe limits, the rupture disk will burst allowinghigh pressure to be discharged through hose to ground.When disk ruptures it will need to be replaced.FuelDiesel fuel must be clean, fresh, meet fuel specifica-tions and be sourced from a known and reputablesupplier. Clean, fresh and properly specified diesel fuelwill provide assurances of maximum engine perfor-mance and maximum fuel injection system longevity.The use of out-of-spec, dirty or questionable qualitydiesel fuel will result in engine performance and startability problems as well as reductions in engine and fuelinjection system life.Use clean fuel oil that is not contaminated with waterand debris. Replace fuel filter and drain tank every 100hours of operation.The fuel tank is for both the engine and burner. Theengine requires specific fuel recommendations whichshould be used for both engine and burner.Diesel engines are designed to operate on Ultra LowSulfur Diesel fuel. However, some geographical areas,change the diesel fuel supply depot to No. 1 diesel fuelin the winter months because of the cool wintertemperatures. No. 2 diesel fuel provides maximumviscosity and lubricity but can have "waxing" problemsat lower temperatures. We expressly recommend theuse of No. 2 diesel fuels when temperatures are at orabove 14°F. We recommend that No. 1 diesel fuel beused when temperatures are at or below 14°F. The useof either EPA-high sulfur, off-highway diesel fuel orEPA-low sulfur, on-highway fuel for non-CARB certifiedengines is allowed. CARB certified engines mustconsume only EPA-low sulfur diesel fuels conforming toEPA 40 CFR 86-113-94.We do not recommend the use of "heating oil", blendedfuel/waste engine oil or low grade diesel fuel of anykind. The use of aviation fuels - JP4, JP5 or JP8 mustbe approved on an application basis and is not recom-mended for broad range commercial applications.Fuel Control SystemThis machine utilizes a fuel solenoid valve located onthe fuel pump to control the flow of fuel to the combus-tion chamber. The solenoid, which is normally closed, isactivated by a flow switch when water flows through it.When the operator releases the trigger on the spraygun, 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 fuelto the combustion chamber. Controlling the flow of fuelin this way gives an instantaneous burn-or-no-burn situ-ation, thereby eliminating high and low water tempera-tures and the combustion smoke normally associatedwith machines incorporating a spray gun. Periodicinspection, to insure that the fuel solenoid valvefunctions properly, is recommended. This can be doneby operating the machine and checking to see that theburner is not firing when the spray gun is in the OFFposition.Fuel Pressure AdjustmentTo control water temperature, adjust fuel pressure byturning the regulating pressure adjusting screwclockwise to increase, counterclockwise to decrease.Do not exceed 200 psi.NOTE: : When changing fuel pump, a bypass plugmust be installed in return port or fuel pump will notprime.Burner NozzleKeep the tip free of surface deposits by wiping it with aclean, solvent saturated cloth, being careful not to plugor enlarge the nozzle. For maximum efficiency, replacethe nozzle each season.Engine OilKubota recommends engine oil 10W-30 API rating ofCF or higher.Landa SLT/SLX Diesel Dealer’s Manual 9.807-539.0 - AE
