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.

STEP 1: Use 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 suction tube into the detergent container.

STEP 2: Apply safety latch to spray gun trigger. Secure black detergent nozzle into quick coupler.

NOTE:

Detergent cannot be applied using the Yellow nozzle.

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 injection system after each use by placing the suction tube into a bucket of clean water, then run the pressure washer in low pressure 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

• 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.

PREVENTATIVE MAINTENANCE

1. 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 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:

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.

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.

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.

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 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.

LANDA SEHW • 8.913-932.0 • Rev. 02/12a

MAINTENANCE & SERVICE

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:

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)

Air Adjustment:

as can be obtained, then repeat the above procedure on the air band setting.

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 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.

If the desired position cannot be obtained using only the air shutter, lock the air shutter in as close a position

Deliming Coils:

Periodic flushing of coils is recommended.

Step 1 Fill the float tank with 4 gallons of water, then add 1 lb. of deliming powder.

Mix thoroughly.

Step 2 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.

Step 3 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.

Step 4 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.

Unloader Valve:

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.

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.

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.

MAINTENANCE & SERVICE

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 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. Remove tank top wrap exposing insulation and coil.

8. Bend back insulation tabs.

9. Carefully 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.

LANDA LIMITED NEW PRODUCT WARRANTY

PRESSURE WASHERS

WHAT THIS WARRANTY COVERS

All LANDA pressure washers are warranted by LANDA to the original purchaser to be free from defects in materials and workmanship under normal use, for the periods specified below. 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.
