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.
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: Turn variable pressure control valve on the wand counter clockwise for low pressure until you observe detergent flowing through the detergent pickup tube
Detergent Injector
STEP 3: 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 with detergent valve open 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.Select and install the desired high pressure nozzle.
CAUTION: Remove of the pick up tube from detergent bucket will draw air into pump causing cavitation and low pressure.

Maintenance
Storage
CAUTION: Always store your pressure washer in a location where the temperature will not fall below
32°F (0°C). The pump in this machine is susceptible to permanent damage if frozen. FREEZE DAMAGE
IS NOT COVERED BY WARRANTY.
1.
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 gas 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.
When 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 gasoline from fuel tank, fuel line, fuel valve and carburetor.
3.
Pour about one teaspoon of engine oil through spark plug hole, pull 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 pressure washer and store in a clean, dry place that is well ventilated away from open flame or sparks.
NOTE: The use of a fuel additive, such as STA-BIL
®
, or an equivalent, will minimize the formulation of fuel deposits during storage. Such additives may be added to gasoline in fuel tank of the engine, or to gasoline in a storage container.
After Extended Storage
CAUTION: Prior to restarting, thaw out any possible ice from pressure washer hoses, spray gun or wand.
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.
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 de-scale 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 clean fuel-kerosene, No. 1 fuel oil, or diesel.
Clean or replace fuel filter every 100 hours 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 the engine or burner assembly or any electrical component.
11. Periodically de-lime coils as per instructions.
12. Check to see that engine is properly lubricated.
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.
14 Landa PGHW Operator’s Manual 8.916-485.0 - Y
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 SAE 10W-40 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.
Maintenance
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).

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.
Landa PGHW Operator’s Manual 8.916-485.0 - Y 15
Maintenance
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 fuel 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.
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 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 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.

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.
Maintenance
Coil Removal
Removal of 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 the thermostat sensor making sure you do not crimp the capillary tube.
3.
Remove burner assembly from combustion chamber.
4.
Remove the 3-3/8” bolts from each side of coil and tank assembly (these bolts are used to fasten tank to chassis).
5.
Remove fittings connected to the 1/2” pipe nipples from inlet and discharge sides of coil.
6.
Remove top tank wrap, bend back insulation tabs and fold back blanket.
7.
Remove bolts that hold down coil to bottom wrap.
8.
Remove coil.
9.
Replace or repair any insulation found to be torn or broken.
10. Remove insulation retainer plates.
Coil Reinstallation
To reinstall new or cleaned coil, reverse steps 9 through
1.
CAUTION: If white smoke appears from burner exhaust vent during start-up or operation, discontinue use and readjust air bands.
NOTE: If a flue is installed, have a professional serviceman adjust your burner for a #1 or #2 smoke spot on the Bacharach scale.

Unloader Adjustment Procedures
1. Remove lock nut (Item 19).
2. Remove adjustment knob (Item 18).
3. Loosen the two (2) nuts (Item 15), move them upward on stem (Item 8) until you see 4 or more threads below the nut.
4. Re-attach adjusting knob (Item 18).
5. Start machine. Open the trigger of the spray gun. Increase pressure by turning adjustment knob (Item 18) clockwise until pressure is at the desired operating pressure.
6. Remove the adjustment knob (Item 18), tighten the lower nut (Item 15) tightly against the upper nut (Item 15).
Re-attach adjustment knob (Item 18) and screw down until contact is made with the nuts (Items 15). Screw down lock nut (Item 19) onto the stem (Item 8) until the threads cut into the nylon insert of the lock nut
(Item19).
* If adjustment knob (Item 18) DOES NOT make contact with upper nut (Items 15), remove adjusting knob (Item
18), re-adjust (raise) nuts (Items 15) on stem (Item 8) and re-attach adjustment knob (Item 18), then repeat step #6.
** If adjustment knob (Item 18) DOES make contact with upper nut; release the trigger of the spray gun and watch the pressure gauge for the pressure increase (“spike”). This “spike” SHOULD NOT exceed 500 psi above the operating pressure. If “spike” pressure exceeds the 500 psi limit, remove the adjusting knob (Item
18) and re-adjust (lower) the nuts (Items 15) on the stem (Item 8). Re-attach the adjusting knob (Item 18), then repeat step #6.
