PREVENTATIVE MAINTENANCE
1. Checkto seethatwater pumpis properly lubricated.
2. Followwinterizinginstructionstopreventfreezedam-
age to pump and coils.
3. Always neutralize and flush detergent from system
after use.
4. If waterisknown tobe highinmineral content,use a
watersoftener onyourwater system,or de-scaleas
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.
Cleanor replacefuel filterevery100 hoursof opera-
tion.Avoidwater contaminatedfuel asitwill damage
the fuel pump.
9. If machine is operated with smoky or eye burning
exhaust, coils will soot up, not letting water reach
maximumoperatingtemperature.
10. Never allowwatertobesprayedonornear theengine
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.
Thearea aroundtheLanda washershould bekeptclean
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-
foreshipping.Occasional adjustmentoftheunloadermay
be necessary to maintain correct pressure.
Winterizing Procedure:
Damage due to freezing is not covered by warranty.Ad-
hereto thefollowingcold weatherprocedures 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
airis available,anair fitting canbe screwed intothe 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 WaterThermostat:
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
coolsthen automaticallyreset itself.Thethermostatsen-
sor is located on the discharge side of the heating coil.
Thethermostatcontroldial islocatedon thecontrol panel.
Pumps:
Use only SAE 30 weight non-detergent oil. Change oil
after first 50 hours of use.Thereafter, change oil every
threemonths orat 500hour intervals.Oil levelshould 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
bytheextremeheat buildup inthe coil.Thebest preven-
tativeforliming conditionsis touse highquality cleaning
detergents.In areas where alkaline water is an extreme
problem,periodicuse ofLandaDelimingPowder(C-Tech
Part #9-028008) will remove lime and other deposits
beforecoil becomesplugged.(See Deliminginstructions
for use of Landa Deliming Powder.)
Deliming Coils:
Periodicflushing ofcoilsoroptional floattankisrecommended.
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 Removewandassemblyfromspraygun andput
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.
Removal of Soot and Heating Coil:
In the heating process, fuel residue in the form of soot
depositsmaydevelop betweenthe heatingcoil pipeand
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 9).

TNT SERIES PRESSUREWASHER OPERATOR’S MANUAL

Rupture Disk:
If pressure from pump or thermal expansion should ex-
ceed safe limits, the rupture disk will burst allowing high
pressuretobe dischargedthroughhoseto 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 fuel tank. Gasoline is more
combustible than fuel oil and could result in a serious ex-
plosion.NEVER usecrankcaseorwasteoilinyourburner.
Fuel unit malfunction could result from contamination.
Fuel Control System:
This machine utilizes a fuel solenoid valve located on the
fuelpumptocontroltheflowoffueltothecombustioncham-
ber.Thesolenoid, whichisnormallyclosed,isactivatedby
aflowswitchwhenwaterflowsthroughit.Whentheopera-
tor releases the trigger on the spray gun, the flow of water
throughtheflowswitch stops,turningoff theelectricalcur-
rent to the fuel solenoid.
The solenoid then closes, shutting off the supply of fuel to
thecombustionchamber.Controllingtheflowof fuelinthis
way gives an instantaneous burn-or-no-burn situation,
thereby eliminating high and low water temperatures and
thecombustionsmokenormallyassociatedwithmachines
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
checkingtoseethatthe burner isnotfiringwhen thespray
gun is in the OFF position.
Fuel Pressure Adjustment:
Tocontrolwatertemperature,adjustfuelpressurebyturn-
ing the regulating pressure adjusting screw clockwise to
increase, counterclockwise to decrease. Do not exceed
200psi. NOTE: Whenchanging fuelpump,abypassplug
mustbe installedinreturnportorfuel pumpwillnot prime.
DC Electrodes Setting
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- elevation100'.A one-timeinitial correctionforyour
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.
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. Removeburner assemblyfromcombustionchamber.
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.
