STEP 2: Water source for machines should be supplied by a 3/4" I.D. garden hose with a city water pressure of not less than 30 PSI. If the water supply is inadequate, or if the garden hose is kinked, the machine will run very rough and the burner will not fire. STEP 3: Fill fuel tank with proper fuel: kerosene, No. 1 home heating fuel or diesel. STEP 4: Adding exhaust vent pipe to your oil fired burner is not recommended because it restricts air flow. This causes carbon build-up, which affects the operation and increases maintenance on the coil. If a stack must be used, refrain from using 90° bends. If the pipe can not go straight up then use only 45° bends and go to the next larger size pipe. The overall pipe length must not exceed 6 feet in length. Air adjustments will be required after installation. 10 Landa PHW Operator's Manual 8.917-417.0 - E Operations Operation Instructions STEP 1: Machines must be stored indoors when not in use.

Landa PHW Operator's Manual 8.917-417.0 - E 11 Operations Detergents & General Cleaning Techniques WARNING WARNING: Some detergents may be harmful if inhaled or ingested, causing severe nausea, fainting or poisoning. The harmful elements may cause property damage or severe injury. AVERTISSEMENT: Certains détergents peuvent être dangereux s'ils sont inhalés ou ingérés, provoquant de fortes nausées, des évanouissements et l'empoisonnement. Les éléments dangereux peuvent causer des dommages à la propriété ou des blessures graves. STEP 1: Use Landa detergent designed specifically for pressure washers. Household detergents could damage the pump. Prepare detergent solution as required by the manufacturer. Fill a container with pressure washer detergent. Place the filter end of detergent pick- up tube into the detergent container. Detergent Bucket (not Included) DVSAEOLTUVPUEALRPAEGDDEEEDNDEETTTEERVREAGNLETENVTE Detergent Valve Detergent Pick-Up Tube STEP 2: Turn detergent valve counterclockwise until desired amount of detergent flow is achieved. STEP 3: With the motor running, pull trigger to operate machine. 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. Then run the pressure washer for 12 minutes. Turn detergent valve clockwise after flushing with clean water to prevent air from entering pump. Thermal Pump Protection If you run your pressure washer for 3 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 · Acid-based products These chemicals will harm the machine and will damage the surface being cleaned. Rinsing It will take a few seconds for the detergent to clear. Apply safety latch to spray gun. Remove black soap nozzle from the quick coupler. Select and install the desired high pressure nozzle. NOTE: You can also stop detergent from flowing by simply removing detergent siphon tube from bottle. 12 Landa PHW Operator's Manual 8.917-417.0 - E Shutdown Instructions Burner Switch PHW STEP 1: Remove detergent suction tube from container and insert into one (1) gallon of fresh water.

Landa PHW Operator's Manual 8.917-417.0 - E 13 Maintenance Preventative Maintenance · Use clean fuel - kerosene, No. 1 home heating fuel or diesel. Clean or replace fuel filter every 100 hours of operation. Avoid water contaminated fuel as it will seize up the fuel pump. Desoot coils monthly or use an additive if diesel is being used. · Check to see that water pump is properly lubricated. · Follow winterizing procedure to prevent freeze damage to pump and coils. · Always flush detergents from system after use. · If water is known to be high in mineral content, use a water softener on your water system or use a LANDA recognized coil cleaning detergent. · Do not allow acidic, caustic or abrasive fluids to be pumped through the system. · Always use high grade quality LANDA cleaning detergents. · Never run pump dry for extended periods of time. · Periodically descale coils per instructions. · If machine is operated with smoky or eyeburning exhaust, coils will soot up and prevent water from reaching maximum operating temperature. See section on burner adjustments. Maintenance And Service Pump Lubrication Use only LANDA SAE 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 red dot visible through oil gauge window. Oil should be maintained at that level Fuel Use clean (not contaminated with water and debris) kerosene, No. 1 home heating fuel or diesel. Drain fuel tank and replace fuel filter every 100 hours of operation. Electrode Setting 1/8" Gap Electrode 10/32" Ignition Circuit Periodically inspect wires, spring contact and electrodes for condition, security and proper spacing. Transformer test: CAUTION: 10,000 volts -- use defect free insulated screwdriver and keep fingers off blade! Lay blade across one contact: OK if arc will span 1/2" between end of blade and other contact (see illustration below). Transformer Check OHEILOY,RUIA.S,.A. Fuel Control System These machines utilize a fuel solenoid valve located on the fuel pump to control the flow of fuel to the combustion chamber. This solenoid, which is normally closed, is activated by the flow switch. When an operator releases the trigger on the spray gun, the unloader goes into a by-pass mode, thus stopping electrical current to the fuel solenoid coil. With the solenoid closed, the fuel supply to the combustion chamber ceases. 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 when the spray gun is in the off position, the burner is not firing. Fuel Pressure Adjustment To adjust fuel pressure, turn the 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 line port or fuel pump will not prime. Burner Nozzle Keep tip free of surface deposits by wiping with clean, solvent-saturated cloth, being careful not to plug or enlarge nozzle. For maximum efficiency, replace nozzle each season. 1/16" Nozzle 14 Landa PHW Operator's Manual 8.917-417.0 - E Maintenance Wayne 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. 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. 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. 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. 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 readjust air bands. 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. Landa PHW Operator's Manual 8.917-417.0 - E 15 Maintenance Cleaning of Coils In alkaline water areas lime deposits can accumulate rapidly inside the coil pipes. This growth is increased by the extreme heat buildup in the coil. 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. Spray Nozzles Each machine is equipped with four spray nozzles. Different spray nozzles are calibrated for each machine depending on the flow and pressure of that particular model. Spray nozzles vary in bore size and angle of spray. Popular spray angles are 15°, 25° and 40°. When ordering, please specify size and angle of nozzle. Nozzle size for each machine is located on the serial plate. 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 manufacturer's warranty. (Consult your local LANDA Dealer for the correct procedures.) 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 the winter months, when temperatures drop below 32° F, protecting your machine against freezing is necessary. Siphoning a small amount of antifreeze into the system is recommended. Pouring a 50/50 mix of antifreeze and water into the float tank and then siphon 100% antifreeze through the detergent line with the pump on. If compressed air is available, an air fitting can be screwed into the float tank strainer fitting and, by injecting compressed air, all water will be blown out of the system. Low Pressure Diagnosis Refer to the low pressure section of the troubleshooting guide. If, by referring to the guide, the trouble is found to be either the unloader or pump, your next step is to determine which is the problem. This can be done by eliminating the unloader from the system and attaching the discharge hose directly to the pump. If high pressure is present, then the unloader needs repairing or replacing. CAUTION: When using this procedure to test components, keep spray gun open at all times. ATTENTION: Lorsque cette procédure est utilisée pour tester les composants, garder le pistolet pulvérisateur ouvert en tout temps. 16 Landa PHW Operator's Manual 8.917-417.0 - E Maintenance Coil Removal Removal of the coil because of freeze breakage or to clean soot from it, can be done quickly and easily. 1. Disconnect hose from pump/unloader to inlet side of coil. 2. Disconnect the electrical connections to the thermostat or remove thermostat sensor. 3. Remove all the fittings from the discharge and inlet side of the coil. 4. Remove burner assembly from combustion chamber. 5. Remove 3 - 3/8" bolts from either side of coil and tank assembly (these bolts are used to fasten tank and handles to chassis). 6. Remove the two 3/8" nuts which are underneath the bottom wrap (to keep the coil from moving). 7. Remove tank top wrap exposing insulation and coil. Carefully bend insulation tabs at exhaust stack. 8. Carefully fold back insulation and remove the coil. 9. Replace or repair any insulation found to be torn or broken. 10. Reinstall new or cleaned coil by reversing steps 8 through 1. Temperature and Pressure Relief Valve (Pump Protector) Machines with spray gun control offer the operator the convenience of stopping and starting the flow of water at the end of the discharge hose. When the spray gun stops the flow of water, the unloader valve, back at the machine, opens and recycles the cold water back to the inlet side of the pump. Recycling for longer than five minutes causes the cold water within the pump to heat up. To avoid damage to the pump, a temperature and pressure relief valve is installed next to the inlet side of the pump that will open in the event the water temperature exceeds 140° F. Therefore, while operating the machine, do not leave the spray gun closed for an extended period of time. High Limit Hot Water Thermostat For safety, PHW machines are equipped with adjustable thermostats. If the temperature of the water should exceed its operating temperature, the adjustable thermostat will turn the burner off until the water cools, then it will automatically reset itself. 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. Optional Time Delay Shutdown Operation Once the spray gun trigger is released, the shutdown timer becomes activated. The machine will continue to run in by-pass mode until the timer reaches its preset time, 3 minutes. When that time is reached, the machine shuts down. To restart, push the pump switch forward. Optional Auto Start/stop Timer Operation Once the pump switch is turned on, simply triggering the spray gun is all it takes to start the machine. Once the trigger is released the timer will let the machine bypass water for 15 seconds. It also starts an internal 5 to 60 minute lockout timer. This feature is totally adjustable by the operator by adjusting the knob at the top of the timer. We recommend setting the timer for 15 minutes. To reset the lockout feature, operator must trigger the spray for 10 full seconds. Landa PHW Operator's Manual 8.917-417.0 - E 17 Maintenance Preventative Maintenance This pressure washer was produced with the best available materials and quality craftsmanship. However, you as the owner have certain responsibilities for the correct care of the equipment.
