Clean or replace fuel filter every 100 hours of operation. Avoid water contaminated fuel as it will cause the fuel pump to seize. De-soot coils monthly or use an additive if diesel is being used. 2.Check to see that water pump is properly lubricated (see pump lubrication below). 3.Follow winterizing procedures to prevent freeze damage to pump and coils. 4.Always flush detergent from system after use. 5.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. 6.Do not allow acidic, caustic or abrasive fluids to be pumped through system. 7.Always use high grade quality Landa cleaning detergents. 8.Never run pump dry for extended periods of time. 9.Periodically delime coils as per instructions. 10.If machine is operated with smoky or eye-burning exhaust, coils will soot up, preventing water from reaching maximum operating temperature. (See section on Burner Adjustments). MAINTENANCE & SERVICE Pump Lubrication: TRANSFORMER CHECK ELECTRODE SETTING: WAYNE Gap 1/8" 1/8" Electrodes 3/8" 1/2" 3/16" Top View 2-7/8" Nozzle Adapter Side View Periodically Check Wiring Connections. If Necessary To Adjust Electrodes, Use Diagram ELECTRODE SETTING: BECKETT Use only SAE 30 weight non-detergent oil. Change oil after first 50 hours of use. Thereafter, change oil every three months 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. 5/32" Gap Electrode 7/16" Fuel: Use clean fuel oil that is not contaminated with water and debris. Use kerosene, No. 1 home heating fuel or diesel. Drain fuel tank and replace fuel filter every 100 hours of operation. 1/16" Nozzle Fuel Control System: 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.) These machines utilize a fuel solenoid valve located on the fuel pump to control the flow of fuel to the combustion chamber. This solenoid valve, which is normally closed, is activated by a flow switch when water is flowing through it. When an operator releases the trigger on the spray gun, the flow of water through the flow switch stops, turning off the 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 allows for an instantaneous burn or no burn situation, thereby eliminating high and low water temperatures, and combustion smoke normally associated with machines incorporating a spray gun. 16 LANDA SEHW • 8.913-932.0 • Rev. 02/12a CAUTION: Periodic inspection is recommended to insure that the fuel solenoid valve functions properly. This can be done by operating the machine and checking to see that when the trigger on the spray gun is in the off position, the burner is not firing. Fuel Pressure Adjustment: Air Adjustment: AIR SHUTTER LOCKING SCREW 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. 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. Cleaning of Coils: In alkaline water areas, lime deposits can accumulate rapidly inside the coil pipes. 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 Deliming Powder (Landa Part #9-028008) will remove lime and other deposits before coil becomes plugged. (See Deliming Instructions for use of Landa Deliming Powder.) AIR SHUTTER AIR BAND AIR BAND LOCKING SCREW The oil burner on this machine is preset for operation at altitudes below 1000 feet. If operated at higher altitudes, it may be necessary to adjust the air band setting. Adjust air band for a #1 or #2 smoke spot on the Bacharach scale. A one-time initial correction for your location will pay off in economy, performance, and extended service life. If a smoky or eye-burning exhaust is being emitted from the stack, two things should be checked. First, check the fuel to be certain that kerosene or No. 1 home heating fuel is being used. Next, check the air adjustment on the burner. An oily, smoky fire indicates a lack of air and the air band should be moved to allow the air to flow through the burner. Sharp eye-burning fumes indicate too much air flowing through the combustion chamber. The air band should be readjusted to allow less air to flow through the burner. To adjust: start machine and turn burner ON. Loosen two locking screws found in the air shutter openings (refer to illustration on page 8) and close air shutter until black smoke appears from burner exhaust vent. Note air band position. Next, slowly open the air shutter until white smoke just starts to appear. Turn air shutter halfway back to the black smoke position previously noted. Tighten locking screws. OPERATOR’S MANUAL To adjust fuel pressure, turn the pressure adjusting screw clockwise to increase, counterclockwise to decrease. Do not exceed 200 psi. NOTE: When changing fuel pump, a by-pass plug must be installed in return line port or fuel pump will not prime. (See illustration) as can be obtained, then repeat the above procedure on the air band setting. PRESSURE WASHER MAINTENANCE & SERVICE Deliming Coils: Periodic flushing of coils is recommended. Step 1 Step 2 Step 3 Step 4 Fill the float tank with 4 gallons of water, then add 1 lb. of deliming powder. Mix thoroughly. Remove nozzle from the wand assembly and put the wand and spray gun into float tank. Attach a nylon stocking to the end of the wand to collect debris. Turn pump switch on, allowing solution to be . pumped through coils and back into the float . tank. Solution should be allowed to circulate . 2 - 4 hours. After circulating solution, clean and drain float tank and flush entire system with fresh water. Replace nozzle in wand. Spray Nozzles: Each machine is equipped with one spray nozzle. 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 0°, 15°, 25°, 40°. When ordering, please specify size and angle of nozzle. Nozzle size for each machine is located on the serial plate. If the desired position cannot be obtained using only the air shutter, lock the air shutter in as close a position LANDA SEHW • 8.913-932.0 • Rev. 02/12a 17 PRESSURE WASHER OPERATOR’S MANUAL MAINTENANCE & SERVICE Unloader Valve: Coil Removal: The unloader valve traps pressure in the line when the spray gun is closed. Machines with 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. Occasional adjustment of the unloader may be necessary to maintain correct pressure. Consult your local Landa Dealer for the correct procedure in adjusting the unloader valve. Removal of the coil, because of freeze breakage or to clean soot from it, can be done quickly and easily. 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. Siphoning a small amount of antifreeze into the system is recommended. This is done by pouring a 50/50 mix of antifreeze and water into the float tank and then siphoning 100% antifreeze through the detergent line with the pump on. If compressed air is available, an air fitting can be screwed into float tank strainer fitting and, by injecting compressed air, all water will be blown out of the system. Low Pressure Diagnosis: Refer to Troubleshooting Chart for low pressure. If, by referring to the chart, 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. 1.Disconnect hose from pump to inlet side of the coil. 2.Carefully disconnect thermostat sensor, making sure you do not crimp capillary tube. 3.Remove all the fittings from the inlet and discharge side of coil. 4.Remove the burner assembly from the combustion chamber. 5.Remove the 3-3/8" bolts from each side of coil and tank assembly (these bolts are used to fasten tank and handles to chassis). 6.Remove the two bolts which are underneath the bottom wrap (to keep the coil from moving). 7.R emove tank top wrap exposing insulation and coil. 8. Bend back insulation tabs. 9.C arefully fold back the insulation and remove insulation retainer plates and coil. 10.Replace or repair any insulation found to be torn or broken. 11.To reinstall new or cleaned coil, reverse steps 9 through 1. High Limit Hot Water Thermostat: For safety, each machine is equipped with a high limit control switch. In the event the temperature of the water should exceed its operating temperature the high limit control will turn the burner off until the water cools. CAUTION: The thermostat uses a capillary tube. Do not bend or strike with any object. CAUTION: When using this procedure to test components, keep spray gun open at all times. 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 which follow. 18 LANDA SEHW • 8.913-932.0 • Rev. 02/12a Top Wrap PRESSURE WASHER COIL REMOVAL & INSTALLATION Insulation 3/8" Screw Insulation Tabs Burner Assembly OPERATOR’S MANUAL Coil Hold Down Bolt Insulation Retainer Plate 1/2" Pipe Nipple Rupture Disk 1/2" Pipe Nipple Rupture Disk Hose 89139320-3 Capillary Tube Thermostat Sensor Discharge Manifold 19 LANDA SEHW • 8.913-932.0 • Rev. 02/12a PRESSURE WASHER EXPLODED VIEW - LEFT SIDE 20 1 OPERATOR’S MANUAL 6 10 11 2 25 8 24 9 23 16 12 21 26 19 22 16 27 26 86 17 17, 28,41 13 41 77 26 29 14 14 61 15 15 26 34 59 73 78 60 38 88 60 30 4 5 89 88 87 58 40 46 89139320-4 36 35 57 90 91 20 LANDA SEHW • 8.913-932.0 • Rev. 02/12a 45 18 33 67 47 53 55 56 50 94 72 54 51 85 50 74 44 52 95 93 75 26 49 66 76 96 28 42 25 65 63 17,80 28 17 43 62 3 17 81 79 64 OPERATOR’S MANUAL To Control Panel Valve 92 PRESSURE WASHER EXPLODED VIEW - RIGHT SIDE 89 68 3 93 48 82 48 28 28 83 17 71 For Detail See Float Tank Illus. 70 69 32 For Detail See Control Panel Illus. 83 84 89139320-5 21 LANDA SEHW • 8.913-932.0 • Rev. 02/12a PRESSURE WASHER OPERATOR’S MANUAL EXPLODED VIEW PARTS LIST ITEM PART NO.

This Limited Warranty is subject to the exclusions shown below, is calculated from the date of the original purchase, and applies to the original components only. Any parts replaced under this warranty will assume the remainder of the part’s warranty period. SEVEN YEAR PARTS AND ONE YEAR LABOR WARRANTY: Components manufactured by LANDA, such as frames, handles, top and bottom wraps, float tanks, fuel tanks, belt guards, and internal components on the oil-end of Landa manufactured pumps. General, AR, Liberty, Comet and swash and wobble plate pumps have a one year warranty. Heating coils have a five year warranty from date of original machine purchase. ONE YEAR PARTS AND ONE YEAR LABOR WARRANTY: All other components, excluding normal wear items as described below, will be warranted for one year on parts and labor. Parts and labor warranty on these parts will be for one year regardless of the duration of the original component manufacturer’s part warranty. WARRANTY PROVIDED BY OTHER MANUFACTURERS: Motors, generators, and engines, which are warranted by their respective manufacturers, are serviced through these manufacturers’ local authorized service centers. LANDA is not authorized and has no responsibility to provide warranty service for such components. WHAT THIS WARRANTY DOES NOT COVER This warranty does not cover the following items: 1. Normal wear items, such as nozzles, spray guns, discharge hoses, wands, quick couplers, seals, filters, gaskets, O-rings, packings, pistons, pump valve assemblies, strainers, belts, brushes, rupture disks, fuses, pump protectors. 2. Damage or malfunctions resulting from accidents, abuse, modifications, alterations, incorrect installation, improper servicing, failure to follow manufacturer’s maintenance instructions, or use of the equipment beyond its stated usage specifications as contained in the operator’s manual. 3. Damage due to freezing, chemical deterioration, scale build up, rust, corrosion, or thermal expansion. 4. Damage to components from fluctuations in electrical or water supply. 5. Normal maintenance service, including adjustments, fuel system cleaning, and clearing of obstructions. 6. Transportation to service center, field labor charges, or freight damage. WHAT YOU MUST DO TO OBTAIN WARRANTY SERVICE While not required for warranty service, we request that you register your LANDA pressure washer by returning the completed registration card. In order to obtain warranty service on items warranted by LANDA, you must return the product to your Authorized LANDA Dealer, freight prepaid, with proof of purchase, within the applicable warranty period. If the product is permanently installed, you must notify your Authorized LANDA Dealer of the defect. Your Authorized LANDA Dealer will file a claim with Landa, who must subsequently verify the defect. In most cases, the part must be returned to LANDA freight prepaid with the claim. For warranty service on components warranted by other manufacturer’s, your Authorized LANDA Dealer can help you obtain warranty service through these manufacturers’ local authorized service centers. LIMITATION OF LIABILITY LANDA’S liability for special, incidental, or consequential damages is expressly disclaimed. In no event shall LANDA’S liability exceed the purchase price of the product in question. LANDA makes every effort to ensure that all illustrations and specifications are correct, however, these do not imply a warranty that the product is merchantable or fit for a particular purpose, or that the product will actually conform to the illustrations and specifications. Our obligation under this warranty is expressly limited at our option to the replacement or repair at a service facility or factory designated by us, of such part or parts as inspection shall disclose to have been defective. THE WARRANTY CONTAINED HEREIN IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY IMPLIED WARRANTY OF MERCANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE ARE EXPRESSLY LIMITED TO THE DURATION OF THIS WRITTEN WARRANTY. LANDA does not authorize any other party, including authorized LANDA Dealers, to make any representation or promise on behalf of LANDA, or to modify the terms, conditions, or limitations in any way. It is the buyer’s responsibility to ensure that the installation and use of LANDA products conforms to local codes. While LANDA attempts to assure that its products meet national codes, it cannot be responsible for how the customer chooses to use or install the product. Some states do not allow limitations on how long an implied warranty lasts or the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. This warranty gives you specific legal rights and you may also have other rights which vary from state to state.
