tions may result in personal injury or property damage.
2. Turn on water at faucet and pull trigger on spray gun
allowing water to flow until all air has discharged from
system. Check for water leaks; tighten as needed.
3. Pull wand coupler collar back and insert desired pres-
sure nozzle into coupler then secure by pushing col-
lar forward.
NOTE: Variable pressure control wand handle must
be turned clockwise to enable water to flow out of
the high pressure nozzle.
4. Read engine manual, turn on gas valve and choke.
Turn the engine switch to the START position and
hold it there until the engine starts. NOTE: Do not
use the electric starter for more than five seconds at
a time. If the engine fails to start, release the switch
and wait ten seconds before operating the starter
again. When the engine starts, allow the engine
switch to return to the ON position. If the engine is to
be started without the battery, turn switch to start

7. To apply detergent, see “How to Use the Detergent
Injector”(page 8).
GENERAL WASHING
TECHNIQUES
1. Hold spray nozzle approximately one foot from the
surface being cleaned. Spray at an angle to get un-
der the material being removed.
2. When washing large objects, use detergent injector to
apply detergent. Start washing from the bottom and
work up. Better detergent economy and faster results
will be obtained by allowing the detergent to set 5 - 10
minutes. After washing, rinse from the top down.
3. Cleaning heavy dirt or material away with a hard
stream of clear water is recommended before using
a cleaning agent.
SHUT DOWN PROCEDURES
1. Rinse all lines (and injector) with clean water to re-
move any soap residue.
2. Turn burner switch off and continue spraying, allow-
ing the water to cool below 100°F.

HOW TO USE THE
DETERGENT INJECTOR
WARNING:Some detergents may
be harmful if inhaled or ingested
causing severe nausea, fainting
or poisoning. The harmful ele-
ments may cause property dam-
age or severe injury.
The machine can siphon and mix de-
tergents with the use of Landa's de-
tergent injector kit.
1. Pull injector quick coupler collar back and secure on
discharge nipple. Injector valve body arrow should
point in direction of flow.
2. Connect high pressure hose to injector nipple se-
curing quick coupler.
3. Start machine as outlined in Operating Instructions.
4. Place detergent pick-up tube into container of deter-
gent solution.
5. Turn pressure control handle counterclockwise on
the variable pressure wand. This lowers the pres-
sure by directing the water flow through the soap
nozzle and allows the detergent injector to siphon
soap.
6. Open trigger spray gun. Water detergent ratio is ap-
proximately 15 to 1.
7. When you finish washing, rinse by simply turning
the variable pressure wand control handle clockwise
to increase pressure.
NOTE: The detergent injector will not siphon with
water flowing through the high pressure nozzle at
the end of the wand.
8. For clean up, place detergent pick-up tube into con-
tainer of clear water and follow steps 5 and 8 to pre-
vent detergent deposits from damaging the injector.

PREVENTATIVE MAINTENANCE
1. Check to see that the water pump is properly lubri-
cated.
2. Follow winterizing instructions to prevent freeze dam-
age to the 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 in 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 Landa cleaning prod-
ucts.
7. Never run pump dry for extended periods of time.
8. Use clean fuel-kerosene, No. 1 fuel oil or diesel. Re-
place fuel filter every 100 hours of operation. Avoid
water contaminated fuel as it will seize up the fuel
pump.
9. If machine is operated with smoking or eye burning
exhaust, coils will soot up, not letting water reach
maximum operating temperature. (See section on
Air Adjustments.)
10. Never allow water to be sprayed on or near 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 this equipment clean
and dry.
The areas around the Landa washer should be kept clean
and free of combustible materials, gasoline and other
flammable vapors and liquids.
The flow of combustion and ventilating air to the burner
must not be blocked or obstructed in any manner.
MAINTENANCE AND SERVICE
Unloader Valves:
Unloader valves are preset and tested at the factory be-
fore shipping.Occasional adjustment of the unloader may
be necessary to maintain correct pressure. Call your
local dealer for assistance.
Winterizing Procedure:
Damage due to freezing is not covered by warranty. Ad-
here 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 nec-
essary. Store the machine in a heated room. If this is not
possible then mix a 50/50 solution of anti-freeze/water
into a 5 gallon bucket. Place a short section of garden
hose into the bucket and connect it to the machine. El-
evate the bucket and turn the pump on to siphon the
anti-freeze through the machine. If compressed air is
available, an air fitting can be screwed into the inlet con-
nector and, by injecting compressed air, all water will be
blown out of the system.
High Limit Hot Water Thermostat:
For safety, each machine is equipped with a high limit
control switch. In the event that the temperature of the
water should exceed its operating temperature, the high
limit control will turn the burner off until the water cools.
Pumps:
Use only SAE 30W non-detergent oil. Change oil after
the first 50 hours of use.Thereafter, change the oil every
three months or at 500 hour intervals. Oil level should be
checked by using the dipstick found on top of the 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 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 de-
tergents. In areas where alkaline water is an extreme
problem, periodic use of Landa Deliming Powder (part
#9-028008) 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 is recommended.
1. Fill a container or optional float tank with 4 gallons of
water, then add 1 lb. of deliming powder. Mix thor-
oughly.
2. Remove wand assembly from spray gun and put
spray gun into container. Secure the trigger on the
spray gun into the open position.
3. Attach a short section (3-5 ft.) of garden hose to
machine to siphon solution from an elevated con-
tainer. Turn pump switch on, allowing solution to be
pumped through coils back into the container. Solu-
tion should be allowed to circulate 2-4 hours.
4. After circulating solution flush entire system with
fresh water. Reinstall wand assembly to spray gun.

10 MVC SERIES PRESSURE WASHER OPERATOR’S MANUAL
LANDA MVC •#96-61836 •REV. 5/03
Rupture Disk:
If pressure from pump or thermal expansion should ex-
ceed 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.
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 a serious explosion
could result. NEVER use crankcase or waste oil in your
burner. Fuel unit malfunction could result from contami-
nation.
Fuel Control System:
These machines utilize a fuel solenoid valve located on
the fuel pump to control the flow of fuel to the combus-
tion chamber. This solenoid valve, which is normally
closed, is activated by a flow switch when water is flow-
ing 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 allows for an instantaneous burn or no burn
situation, thereby eliminating high and low water tem-
peratures, and combustion smoke normally associated
with machines incorporating a spray gun.
CAUTION: Periodic inspection is recommended to in-
sure that 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.
Electrode Setting:
(See illustration below.)
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:
Machines are preset and performance tested at the fac-
tory - elevation 100 feet. A one-time initial correction for
your location will pay off in economy, performance and
extended service life. If a smoking or eye-burning ex-
haust is being emitted from the stack, two things should
be checked. First, check the fuel to be certain that kero-
sene or No. 1 home heating fuel is being used. Next,
check the air adjustment on the burner.
Initial Air Adjustments:
Allow sufficient air to obtain a clean burning flame by
loosening the lock screws and moving the air shutter
and if necessary the bulk air band.
Reduce the air supply until the flame tips appear slightly
smoky then increase the air just enough to cause the
flame tips to appear absolutely clean.
Periodically check wiring connections. If necessary to
adjust electrodes, use diagram.

Fuel Pressure Adjustment:
To adjust fuel pressure, turn the adjusting screw clock-
wise to increase, counterclockwise to decrease. Do not
exceed 200 psi. NOTE: When changing the fuel pump, a
bypass plug must be installed in the return port or the
fuel pump will not prime.
Removal of Soot and Heating Coil:
In the heating process, fuel residue in the form of soot
deposits may develop on the heating coil 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.
1. Remove the tank head assembly by unscrewing the
three Tek screws and lifting the tank head off.
2. Remove the two pipe nipples and associated fittings.
3. Lift the coil out of the outer wrap.
CAUTION:The coil weighs about 80 lbs. Use proper
lifting techniques.
4. Clean, repair and replace the coil by reversing the
above steps.
Coil Reinstallation:
Reinstall by reversing the above steps 4 through 1.
Final Note:
The 12 VDC burner systems can draw as much as 18
amps! For such motors to run properly, the battery and
engine charging system must be kept in good condition,
and the engine must run fast enough to adequately
charge the battery. Do not throttle down the engine for
any length of time.
