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 and lift it off.
2. When detergent is required for cleaning, start wash-
ing from the bottom and work up. Better detergent
economy and faster results will be obtained by al-
lowing the chemical to set 5-10 minutes. After wash-
ing, rinse from the top down.

HOW TO USE THE OPTIONAL
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
detergents with the use of Landa's
detergent 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 discharge
nipple securing quick coupler.
3. Start machine as outlined in Operating Instructions.
4. Place detergent pick-up tube into container of deter-
gent.
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 spray gun. Water detergent ratio is approxi-
mately 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 deter-
gent with the water flowing through the high pres-
sure nozzle at the end of the wand.

PREVENTATIVE MAINTENANCE
1. Check to see that water pump is properly lubricated.
2. Follow winterizing instructions to prevent freeze dam-
age 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 die-
sel. 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 en-
gine or burner assembly or any electrical compo-
nent.
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.
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.
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 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 tempera-
ture 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 sen-
sor 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 preven-
tative 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 #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 or optional float tank is recom-
mended.
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 solu-
tion 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.

10 PGHW SERIES PRESSURE WASHER OPERATOR’S MANUAL
LANDA PGHW •96-6031 • REV. 7/03
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 on page 11).
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. Torque new rup-
ture disk to 35 ft. lbs.
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 ex-
plosion. 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 cham-
ber.The solenoid, which is normally closed, is activated by
a flow switch when water flows through it.When the opera-
tor releases the trigger on the spray gun, the flow of water
through the flow switch stops, turning off the electrical cur-
rent 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 recom-
mended. 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 turn-
ing 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.
Electrodes Setting: Wayne
(See Illustration Below)
Electrodes Setting: Beckett
(See Illustration Below)
Air Adjustment:
Machines are preset and performance tested at the fac-
tory - elevation 100'. A one-time initial correction for your
location will pay off in economy, performance, and ex-
tended 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 kero-
sene or No. 1 home heating fuel is being used. Next,
check the air adjustment on the burner.
