WARNING

DETERGENTS & GENERAL WASHING TECHNIQUES

PRESSURE WASHER

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.

Detergent Valve

Detergent Tube

STEP 2: With the engine run-

ning, 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 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.

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

Landa SLT/SLX Diesel • 8.914-003.0 • Rev. 12/11

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 and close detergent valve. Select and install the desired high pressure nozzle.

off.

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 fuel 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 diesel from fuel tank, fuel line, fuel valve and carburetor.

3. Pour about one teaspoon of engine oil through the

10

spark plug hole, pull the starter grip several times

Landa SLT/SLX Diesel • 8.914-003.0 • Rev. 12/11

STORAGE

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 shortage. 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.

MAINTENANCE & SERVICE

PREVENTATIVE

MAINTENANCE

Check to see that water pump is properly lubricated.

• Follow winterizing instructions to prevent freeze

PRESSURE WASHER

damage to pump and coils.

• Always neutralize and ﬂush detergent from system after use.

• If water is known to be high in mineral content, use a water softener on your water system, or de-scale as needed.

• Do not allow acidic, caustic or abrasive ﬂuids to be pumped through system.

•

Always use high grade quality cleaning products.

•

Never run pump dry for extended periods of time.

• Use clean diesel fuel. Clean or replace fuel ﬁlter every 100 hours of operation. Avoid water contaminated fuel as it will damage the fuel pump.

• If machine is operated with smoky or eye burning exhaust, coils soot up and prevent water from reaching maximum operating temperature. (See section on Burner Adjustments.)

• Never allow water to be sprayed on or near the engine or burner assembly or any electrical component.

• Periodically delime coils per instructions.

• 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 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 the 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.

During winter months, when temperatures drop below 32°F, protecting your machine against freezing

Landa SLT/SLX Diesel • 8.914-003.0 • Rev. 12/11

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 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 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.

Step 4 After circulating solution, ﬂush the entire sys-

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

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. 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 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/diesel 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 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.

OPERATOR’S MANUAL

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-noburn 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.

MAINTENANCE & SERVICE

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.

Air Adjustment

PRESSURE WASHER

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 #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

OPERATOR’S MANUAL

that kerosene or No. 1 home heating fuel is being used. Next, check the air adjustment on the burner.

Coil Removal

Coil removal, because of freeze breakage or to clean soot from it, can be done quickly and easily.

1. Dis c onnect ho se from pump to inlet sid e 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. R e m o v e bo l t s t h a t h o l d d o w n c o i l 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.

LOCKING SCREW

Adjustment

To adjust: start machine and turn burner ON. Loosen

two locking screws found in the air shutter openings (refer to 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 Reinstallation

Reinstall new or cleaned coil reversing Steps 9 through 1.

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). Reattach 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 (Item 19).

*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.
