MAINTENANCE & SERVICE
Check List:
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 diesel. Clean or replace fuel filter every
300 hours or 6 months 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 delime 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.
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.

pressed 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 10/40W 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 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 #8.718-911.0) will remove lime
and other deposits before coil becomes plugged.
(See Deliming instructions for use of Landa Deliming
Powder.)
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.
Winterizing Procedure:
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.
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.
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.
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 com8.920-098.0 • LANDA PDHW Service • REV. 8/12
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:
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. Torque
new rupture disk to 35 ft. lbs.
Fuel:
Diesel fuel must be clean, fresh, meet fuel specifications and be sourced from a known and reputable
supplier. Clean, fresh and properly specified diesel
fuel will provide assurances of maximum engine performance and maximum fuel injection system longevity.
The use of out-of-spec, dirty or questionable quality
diesel fuel will result in engine performance and start
ability problems as well as reductions in engine and
fuel injection system life.
Use clean fuel oil that is not contaminated with water
and debris. Replace fuel filter and drain tank every 100
hours of operation.
All burner combustion system designs are geared
toward the use of commercial grade diesel fuels. As
such, use of fuels other than those designated "DF",
i.e. DF2 (No. 2 Diesel Fuel), will result in degradation
of performance and/or reduction in component life. It
is understood that applications in certain situations require the use of fuels other than No. 2 diesel fuel. See
list of various fuels and comments pertaining to each.
Diesel engines are designed to operate on No. 2 diesel
fuel. However, some geographical areas, change the
diesel fuel supply depot to No. 1 diesel fuel in the winter
months because of the col winter temperatures. No. 2
diesel fuel provides maximum viscosity and lubricity
but can have "waxing" problems at lower temperatures.
We expressly recommend the use of No. 2 diesel fuels
when temperatures are at or above 14°F. We recommend that No. 1 diesel fuel be used when temperatures
are at or below 14°F. The use of either EPA-high sulfur,
off-highway diesel fuel or EPA-low sulfur, on-highway
fuel for non-CARB certified engines is allowed. CARB
certified engines must consume only EPA-low sulfur
diesel fuels conforming to EPA 40 CFR 86-113-94.
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 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.
SERVICE MANUAL
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
17).
We do not recommend the use of "heating oil",
blended fuel/waste engine oil or low grade diesel fuel
of any kind. The use of aviation fuels - JP4, JP5 or
JP8 must be approved on an application basis and
is not recommended for broad range commercial
applications.
PRESSURE WASHER
MAINTENANCE & SERVICE
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.
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.

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.
To Adjust Beckett Burner: 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
