STEP 2: 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

89140020-32

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, open detergent valves then run the pressure washer for 1-2 minutes. Then turn detergent valve clockwise to close, to prevent air from entering pump.

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

Landa SLT/SLX • Gas 8.914-002.0 • Rev. 4/13

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:

89140020-35

STEP 5: Squeeze trigger on spray

gun to relieve remaining pressure.

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 trig-

ger to release pressure.

2. Detach water supply hose and high pressure hose.

3. Turn on the machine for a few seconds, until re-

maining 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 the 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

STEP 3: Turn engine key switch off.

STORAGE

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 the 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 the gasoline in the fuel tank of the engine, or to the 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.

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.

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 factory setting may cause personal injury and/or property damage, and will void the manufacturer's 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.

Landa SLT/SLX • Gas 8.914-002.0 • Rev. 4/13

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 antifreeze and water in the ﬂoat tank. Turn the engine on to siphon the antifreeze 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. 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 20/40 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 the red dot visible through the oil gauge window. Oil should be maintained at that level.

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 prevention for liming conditions is to use high quality cleaning chemicals. 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.

Deliming Coils

Periodic ﬂushing of coils or optional ﬂoat tank is recommended.

Step 1 Fill a container with 4 gallons of water, then

add 1 lb. of deliming powder. Mix thoroughly. Pour mixture into ﬂoat tank.

Step 2 Remove wand assembly from spray gun

and put spray gun into ﬂoat tank. Secure the trigger on the spray gun into the open position.

Step 3 Turn engine on, allowing solution to be

pumped through coils back into the ﬂoat tank. The solution should be allowed to circulate 2-4 hours or until the color changes.

PRESSURE WASHER

OPERATOR’S MANUAL

13

MAINTENANCE & SERVICE

Step 4 After circulating solution, ﬂush the entire

system with fresh water. Clean out ﬂoat tank and then reinstall wand assembly to spray gun.

Removal of Soot and Heating Coil

In the heating process, fuel residue in the form of soot deposits may develop on the heating coil pipe and block air ﬂow which will affect burner combustion.

PRESSURE WASHER

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–page 16).

Pressure Relief Valve

Each machine is equipped with a relief valve to relieve pressure in the system when higher than normal operating pressures are encountered or if the unloader

OPERATOR’S MANUAL

valve should fail. Unusually high pressures come from an object plugging the spray nozzle. If operating pressure is found to be normal and the relief valve continues to leak, repair or replace valve. CAUTION:

This valve must be opened each year to check operation.

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. The ruptured disk needs to be inspected once or twice a year for any obstructions.

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-orno-burn situation, thereby eliminating high and low

water temperatures, and combustion smoke normally associated with machines incorporating a spray gun.

CAUTION: 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 control water temperature, adjust fuel pressure by turning the regulating pressure 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 port or fuel pump will not prime.

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.

Burner Air Adjustment:

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. 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.

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.

To adjust, start the machine and turn burner ON.

Loosen two locking screws found in the air shutter openings (see illustration) 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 as can be obtained, then repeat the above procedure on the air band setting.

Coil Removal

Coil removal, 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 the coil and any insulation found to be broken or torn.

10. Remove insulation retainer plates.
