Detergents & General Cleaning
Techniques
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.
STEP 2:Turn variable pressure control valve on the
wand counter clockwise for low pressure until you
observe detergent flowing through th e det e rgen t pickup tube
STEP 3: 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
not allow detergent to dry on
surface.
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 bo ttom 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 re m ov e stu bb o rn
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.
IMPORTANT: You must flush the detergent
injection system after each use by placing the
suction tube into a bucket of clean water, then run
the pressure washer with detergent valve open 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

Maintenance
Storage
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 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 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
spark plug hole, pull starter grip several 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 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 gasoline in fuel tank of the engine, or to
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.
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 fuel-kerosene, No. 1 fuel oil, or diesel.
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
engine or burner assembly or any electrical

11. Periodically de-lime 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 clo gged or
blocked. Wipe off any oil spills and keep equipment
clean and dry.
Maintenance
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.
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 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
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.
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 Coil
Descaler (part #8.914-296.0) will remove lime and
other deposits before coil becomes plugged.
Periodic descaling of the heating coil is recommended so please consult your local Landa Dealer
for instructions.
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).
Rupture Disk
If pressure from pump or thermal expansion should
exceed safe limits, the rupture disk will burst allowing
high pressure to be discharged thr ough hose to ground.
When disk ruptures it will need to be replaced.
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 10W-40 non-foaming oil. Change oil after
first 50 hours of use. Thereafter, change oil every year
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.
Landa PGHW Operator’s Manual 8.916-485.0 - Y

Maintenance
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-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 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.
Also, as ambient temperature changes seasonally, the
fuel temperature in the feed tank and air temperature
inlet can impact fuel flow. In more extreme temperatures, this local-site adjustment may also require
different fuel nozzles for fuel inlet temperatures that are
at seasonal extremes (higher or lower) in locations
where the temperature changes are beyond moderate
temperatures of between 40°F and 90°F. Colder
temperatures will make for a thicker flow and less fine a
fuel spray while hotter temperatures will make for a
thinner flow a more fine spray with the same nozzle.
Consider alternate nozzle configurations from the
baseline factory-supplied nozzle for operating in such
temperature extremes if performance is not meeting
needs with air band and fuel pressure settings alone.
NOTE: When changing fuel pump, a by-pass plug
must be installed in return line 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 ca refu l not to pl ug
or enlarge the nozzle. For maximum efficiency, replace
the nozzle each season.
Electrodes Setting
Gun Setting for EHASR Only
Fuel Pressure Adjustment
To adjust fuel pressure, First install a pressure gage
into the port just after the pump fuel exit. Turn the
adjusting screw (located at the regulator port)
clockwise to increase, and counterclockwise to
decrease. Do not exceed 200 psi or lower the pressure
below 130 PSI, when checked at the post-pump
pressure port.
The fuel pressure may need to be adjusted due to
altitude. For every 500 ft altitude above sea lev el, th e
boiling point of water goes down 1 °F. At high altitude
environments, this boiling point change may require the
heat input to be lowered so the water input does not
turn to steam earlier than at the factory settings and
activate the pressure sensors and pressure relief
equipment when the unit is operated and much higher
altitudes from factory settings or local dealer site
settings. Check with your dealer before making local
site fuel pressure adjustments.

Oil Burner
Burner Air Adjustment: The oil burner on this
machine is preset for operation at altitudes below 500
feet. If operated at higher altitudes, it may be necessary
to adjust the air band for a #1 or #2 smoke spot on the
Bacharach scale.
To adjust, start machine and turn burner ON. Loosen
two locking screws found on the air band and close air
band until black smoke appears from burner exhaust
vent. Note air band position. Next, slowly open the air
band until white smoke just starts to appear. Turn air
band halfway back to the previously noted position.
Tighten locking screws.
For higher altitudes, the air band opening may need to
be increased; for lower altitude, the .air band may need
to be decreased.
For higher humidity, the air band opening may need to
be increased; for lower relative humidity, the .air band
may need to be decreased.
For higher ambient temperatures the air band opening
may need to be increased; for lower ambient temperatures, the air band opening may need to be decreased.
Adjust to your operating location's environment asneeded for best smoke spot and performance
compliant with local, state, and federal regulations.
Coil Removal
Removal of coil 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 any insulation found to be torn or
broken.
10. Remove insulation retainer plates.
Coil Reinstallation
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 reinstall new or cleaned coil, reverse steps 9 through
1.
