Liquid detergent is drawn into the machine and mixed with water. Apply detergent to work area. Do not allow detergent to dry on surface. IMPORTANT: You must flush the detergent after each use by placing the suction tube into a bucket of clean water, open detergent valves then run the pressure washer for 1-2 minutes. Thermal Pump Protection If you run your pressure washer for 3-5 minutes without pressing the trigger on the spray gun, circulating water in the pump can reach high temperatures. When the water reaches this temperature, the pump protector engages and cools the pump by discharging the warm water onto the ground. This thermal device prevents internal damage to the pump. Cleaning Tips Pre-rinse cleaning surface with fresh water. Place detergent suction tube directly into cleaning solution and apply to surface at low pressure (for best results, limit your work area to sections approximately 6 feet square and always apply detergent from bottom to top). Allow detergent to remain on surface 1-3 minutes. Do not allow detergent to dry on surface. If surface appears to be drying, simply wet down surface with fresh water. If needed, use brush to remove stubborn dirt. Rinse at high pressure from top to bottom in an even sweeping motion keeping the spray nozzle approximately 1 foot from cleaning surface. Use overlapping strokes as you clean and rinse any surface. For best surface cleaning action spray at a slight angle. Recommendations: · Before cleaning any surface, an inconspicuous area should be cleaned to test spray pattern and distance for maximum cleaning results. · If painted surfaces are peeling or chipping, use extreme caution as pressure washer may remove the loose paint from the surface. · Keep the spray nozzle a safe distance from the surface you plan to clean. High pressure wash a small area, then check the surface for damage. If no damage is found, continue to pressure washing. CAUTION - Never use: · Bleach, chlorine products and other corrosive chemicals · Liquids containing solvents (i.e., paint thinner, gasoline, oils) · Tri-sodium phosphate products · Ammonia products and Acid-based products These chemicals will harm the machine and will damage the surface being cleaned. 12 Landa SLT/SLX Kubota Diesel Operator's Manual 9.807-540.0 - F ATTENTION: Ne jamais utiliser : · Eau de Javel, produits à base de chlore et autres produits chimiques corrosifs · Liquides contenant des solvants (c.-à-d. diluant à peinture, essence, huiles, etc.) · Produits à base de tripolyphosphate de sodium · Ammoniac ou produits à base d'acide Ces produits chimiques endommageront la machine et endommager la surface à nettoyer. Rinsing It will take a few seconds for the detergent to clear. Apply safety latch to spray gun and close detergent valve. Select and install the desired high pressure nozzle.

Stop the pressure washer, squeeze spray gun trigger to release pressure. 2. Detach water supply hose and high pressure hose. 3. Turn on the machine for a few seconds, until remaining water exits. Turn engine off immediately. 4. Drain the fuel and oil from the engine. 5. Do not allow high pressure hose to become kinked. 6. Store the machine and accessories in a room which does not reach freezing temperatures. CAUTION: Failure to follow the above directions will result in damage to your pressure washer. ATTENTION: Le non-respect des directives cidessus entraînera des dommages à la laveuse à pression. When the pressure washer is not being operated or is being stored for more than one month, follow these instructions: 1. Replenish engine oil to upper level. 2. Drain diesel from fuel tank, fuel line, fuel valve and carburetor. 3. Pour about one teaspoon of engine oil through the spark plug hole, pull the starter grip several times and replace the plug. Then pull the starter grip slowly until you feel increased pressure which indicates the piston is on its compression stroke and leave it in that position. This closes both the intake and exhaust valves to prevent rusting of cylinder. 4. Cover the pressure washer and store in a clean, dry place that is well ventilated away from open flame or sparks. After Extended Storage CAUTION: Prior to restarting, thaw out any possible ice from pressure washer hoses, spray gun or wand. ATTENTION: Avant de redémarrer, faire fondre la glace se trouvant sur les boyaux, le pistolet pulvérisateur ou la lance de lalaveuse à pression. Engine Maintenance During the winter months, rare atmospheric conditions may develop which will cause an icing condition in the carburetor. If this develops, the engine may run rough, lose power and may stall. This temporary condition can be overcome by deflecting some of the hot air from the engine over the carburetor area. NOTE: Refer to the engine manufacturer's manual for service and maintenance of the engine. Maintenance And Service 1. Check to see that water pump is properly lubricated. 2. Follow winterizing instructions to prevent freeze damage to pump and coils. 3. Always neutralize and flush detergent from system after use. 4. If water is known to be high in mineral content, use a water softener on your water system, or descale as needed. 5. Do not allow acidic, caustic or abrasive fluids to be pumped through system. 6. Always use high grade quality cleaning products. 7. Never run pump dry for extended periods of time. 8. Use Ultra Low Sulfur diesel fuel. Clean or replace fuel filter every 100 ours of operation. Avoid water contaminated fuel as it will damage the fuel pump. 9. If machine is operated with smoky or eye burning exhaust, coils will soot up, not letting water reach maximum operating temperature. 10. Never allow water to be sprayed on or near engine or burner assembly or any electrical component. 11. Periodically descale coils. Consult your local Landa Dealer for instructions. 12. Check to see that engine is properly lubricated. 14 Landa SLT/SLX Kubota Diesel Operator's Manual 9.807-540.0 - F Maintenance It is advisable, periodically, to visually inspect the burner. Check air inlet to make sure it is not clogged or blocked. Wipe off any oil spills and keep equipment clean and dry. The flow of combustion and ventilating air to the burner must not be blocked or obstructed in any manner. The area around the Landa washer should be kept clean and free of combustible materials, gasoline and other flammable vapors and liquids. Unloader Valves Unloader valves are preset and tested at the factory before shipping. Tampering with the factory setting may cause personal injury and/or property damage, and will void the manufacturers warranty. Winterizing Procedure Damage due to freezing is not covered by warranty. Adhere to the following cold weather procedures whenever the washer must be stored or operated outdoors under freezing conditions. During winter months, when temperatures drop below 32°F, protecting your machine against freezing is necessary. Store the machine in a heated room. If this is not possible then mix a 50/50 solution of anti-freeze and water in the float tank. Turn the engine on to siphon the anti-freeze mixture through the machine. If compressed air is available, an air fitting can be screwed into the float tank by removing the float tank strainer and fitting. Then inject the compressed air. Water will be blown out of the machine when the trigger on the spray gun is opened. High Limit Hot Water Thermostat For safety, each machine is equipped with a temperature sensitive high limit control switch. In the event that the water should exceed its operating temperature, the high limit control will turn the burner off until the water cools then automatically reset itself. The thermostat sensor is located on the discharge side of the heating coil. The thermostat control dial is located on the control panel. Pumps Use only 10W-40 weight non-foaming oil. Change oil after first 50 hours of use. Thereafter, change oil every year or at 500 hour intervals. Oil level should be checked through use of dipstick found on top of pump, or the red dot visible through the oil gauge window. Oil should be maintained at that level. Cleaning of Coils In alkaline water areas, lime deposits can accumulate rapidly inside the heating coil. This growth is increased by the extreme heat build up in the coil. The best preventative for liming conditions is to use high quality cleaning detergents. In areas where alkaline water is an extreme problem, periodic use of Landa Coil Descaler (Part # 8.914-296.0) will remove lime and other deposits before coil becomes plugged. Periodic descaling of the heating coil is recommended so please consult your local Landa Dealer for instructions. 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 disk ruptures it will need to be replaced. The Rupture Disk should be replaced every two years. Landa SLT/SLX Kubota Diesel Operator's Manual 9.807-540.0 - F 15 Maintenance Fuel CAUTION: Use Low Sulfur Fuel diesel only. ATTENTION: Utiliser du carburant à faible teneur en soufre seulement. Diesel fuel must be clean, fresh, meet fuel specifications and be sourced from a known and reputable supplier. Clean, fresh and properly specified diesel fuel will provide assurances of maximum engine performance 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. The fuel tank is for both the engine and burner. The engine requires specific fuel recommendations which should be used for both engine and burner. Diesel engines are designed to operate on Ultra Low Sulfur Diesel fuel. However, some geographical areas, change the diesel fuel supply depot to No. 1 diesel fuel in the winter months because of the cool 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 recommend 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 recommended 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 combustion 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 Grade/Type No. 2 Diesel Fuel (DF2) No. 2-DS15 No. 1 Diesel Fuel (DF1) No. 1-D S15 JP 4 Turbine Fuel Comments Recommended fuel type for normal ambient operation Recommended fuel type for cold weather operation in ambients which would result in DF2 "waxing". No degradation in performance or engine/ component life. 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 JP 8 Turbine Fuel JP 5 Turbine Fuel DF A Arctic Comments 5-12% reduction in power and up to 30% reduction in fuel system component and cylinder life. Refer to JP 8 Acceptable fuel for use in sub-zero ambients only. 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 adjust fuel pressure, First install a pressure gage into the port just after the pump fuel exit. Turn the adjusting screw (located at the regulator port) clockwise to increase, and counterclockwise to decrease. Do not exceed 200 psi or lower the pressure below 130 PSI, when checked at the post-pump pressure port. 16 Landa SLT/SLX Kubota Diesel Operator's Manual 9.807-540.0 - F Maintenance The fuel pressure may need to be adjusted due to altitude. For every 500 ft altitude above sea level, the boiling point of water goes down 1 °F. At high altitude environments, this boiling point change may require the heat input to be lowered so the water input does not turn to steam earlier than at the factory settings and activate the pressure sensors and pressure relief equipment when the unit is operated and much higher altitudes from factory settings or local dealer site settings. Check with your dealer before making local site fuel pressure adjustments. Also, as ambient temperature changes seasonally, the fuel temperature in the feed tank and air temperature inlet can impact fuel flow. In more extreme temperatures, this local-site adjustment may also require different fuel nozzles for fuel inlet temperatures that are at seasonal extremes (higher or lower) in locations where the temperature changes are beyond moderate temperatures of between 40°F and 90°F. Colder temperatures will make for a thicker flow and less fine a fuel spray while hotter temperatures will make for a thinner flow a more fine spray with the same nozzle. Consider alternate nozzle configurations from the baseline factory-supplied nozzle for operating in such temperature extremes if performance is not meeting needs with air band and fuel pressure settings alone. NOTE: When changing fuel pump, a by-pass plug must be installed in return line port or fuel pump will not prime. Engine Oil Kubota recommends engine oil 10W-30 API rating of CF or higher. 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. Electrodes Setting SLT- 6 & 8 (only) 5/32" Gap Electrode 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. 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 temperatures, 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 read just air bands. ATTENTION: Si de la fumée blanche s'échappe de l'évacuation du brûleur pendant le démarrage ou le fonctionnement, cesserd'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.
