8.913-943.0 • LANDA HS • Rev. 4/13
Place machine in a convenient location providing ample support, draining and room for maintenance.
Location:
The location should protect the machine from damaging environmental conditions, such as; wind, rain, and freezing.
Machine must be stored indoors when not in use.
1. The machine should be run on a level surface where it is not readily influenced by outside sources such as strong winds, freezing temperatures, rain, etc. The machine should be located to allow accessibility for refilling of fuel, adjustments and maintenance. Normal precautions should be taken by the operator of the machine to prevent excess moisture from reaching the power unit or electrical controls.
2. It is recommended that a partition be made between the wash area and the machine to prevent direct water spray from coming in contact with the machine. Excess moisture reaching any electric components or electrical controls will reduce machine life and may cause electrical shorts.
3. During installation of the machine, beware of poorly ventilated locations or areas where exhaust fans may cause an insufficient supply of oxygen.
Sufficient combustion can only be obtained when there is a sufficient supply of oxygen available for the amount of fuel being burned.
Electrical:
This machine, when installed, must be electrically grounded in accordance to local codes. Check for proper power supply using a volt meter.
INSTALLATION
Placement:
Do not locate near any combustible material.
Keep all flammable material at least 20 feet away.
Allow enough space for servicing the machine.
Local code will require certain distances from floor and walls. (Two feet away should be adequate.)
Water Source:
The water source for the machine should be supplied by a 5/8" 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 attached pressure washer will run very rough and the burner will not fire.
Connection:
Connect the wand, nozzle, hose and spray gun (where applicable). On pipe thread connections, use teflon tape to avoid water leaks. (See Component Identification on page 5.)
Venting:
Adding exhaust vent pipe to your oil fired burner is not recommended. It restricts air flow, causing 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 size pipe. The overall pipe length must not exceed 6 feet in length. Adjust burner air settings after stack is installed

STEP 4:
With the engine 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.
IMPORTANT: The instructions on this page pertain to the pressure washer used in connection with model HS-3000.
8.913-943.0 • LANDA HS • Rev. 4/13
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 and other corrosive chemicals
• Liquids containing solvents (i.e., paint thinners, 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.
SHUTTING DOWN AND CLEAN-UP
Burner

end and, by injecting compressed air, all water will be blown out of the system.
High Limit Thermostat
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 seize up the fuel pump. De-soot coils monthly. Use an additive if diesel is being used.
MAINTENANCE AND SERVICE
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.
4. Always neutralize and 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 de-scale as needed.
Cleaning of Coils
2. Check to see that the attached pressure washer water pump is properly lubricated.
3. Follow winterizing instructions to prevent freeze damage to pump and 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 prevention 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.)
6. Do not allow acidic, caustic or abrasive fluids to be pumped through system.
7. Always use high grade quality Landa cleaning products.
8. Never run attached pressure washer pump dry for extended periods of time.
9. If machine is operated with smoky or eye burning exhaust, coils will soot up, not letting water reach maximum operating temperature. (See section on
Air Adjustments).
Deliming Coils
Periodic flushing of coils or optional float tank is recommended.
Step 1 Fill a container or float tank with 4 gallons of water, then add 1 lb. of deliming powder.
Mix thoroughly.
Step 2 Remove nozzle from wand assembly and put spray gun and wand assembly into float tank. Attach a nylon stocking to the end of the wand to collect debris.
10. Never allow water to be sprayed on or near the motor or burner assembly or any electrical component.
11. Delime coils as per instructions.
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 this equipment clean and dry.
Step 3 Attach a short section (3-5 ft.) of garden hose to the attached pressure washer to siphon solution from an elevated container.
Turn attached pressure washer switch on, allowing solution to be pumped through coils back into the container. Solution should be allowed to circulate 2-4 hours.
Step 4 After circulating solution flush entire system with fresh water. Reinstall high pressure nozzle into wand.
The areas around the Landa washer should be kept clean and free of combustible materials, gasoline and other flammable vapors and liquids.
Removal of Soot and Heating Coil
The flow of combustion and ventilating air to the burner must not be blocked or obstructed in any manner.
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.
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 on page
10).
Rupture Disk
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 use compressed air on the 9 ft. hose
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. Inspect rupture disk annually for any obstructions.
8.913-943.0 • LANDA HS • Rev. 4/13
MAINTENANCE & SERVICE
Fuel
Use clean fuel oil that is not contaminated with water and debris. Replace fuel filter and drain tank every
100 hours of operation. Use No. 1 or No. 2 Heating
Oil (ASTM D306) only.
NEVER
use gasoline in your burner tank. Gasoline is more combustible than fuel oil and could result in a serious explosion.
NEVER
use crankcase or waste oil in your burner. Fuel unit malfunction could result from contamination.
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.
Electrode Setting:

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 adjusting screw
(located at the regulator pressure port) 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.
Air Adjustment
Machines are preset and performance tested at the factory - elevation 100' above sea level. 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, black, 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 white fumes indicate too much air flowing through the combustion chamber. The air band should be moved to allow less air to flow through the burner.
To adjust:
start machine and turn burner ON. Loosen two locking screws found on the air band (refer to illustration) and close openings 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 black smoke position previously noted. Tighten locking screws.
Electrodes Check: Periodically check wiring connections.
If necessary to adjust electrodes, use diagram.
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.
Fuel Control System
The HS-3000 utilizes 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 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 gives 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.
Periodic inspection is recommended to insure that

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.

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.
