Maintenance
Preventative Maintenance
1. Check to see that water pump is properly
lubricated.
2. Follow Winterizing Procedures 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 Landa cleaning
products.
7. Never run pump dry for extended periods of time.
8. Use clean diesel fuel. Replace fuel filter every 100
hours of operation. Avoid water contaminated fuel
as it will seize up the fuel pump.
9. If burner combustion is operated with smoky or eye
burning exhaust, the coils will soot up and not let
water reach maximum operating temperature. (See
section on Burner Adjustments.)
10. Never allow water to be sprayed on or near the
engine or burner assembly or any electrical
component.
11. Periodically de-scale 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 area 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.
Unloader Valves
Unloader valves relieve pressure in the line when the
spray gun is closed. Unloader valves are preset and
tested at the factory before shipping. Occasional
adjustment of the unloader may be necessary to
maintain correct pressure.
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
40°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. If compressed air is avail
-
able, screw an air fitting into the anchor connector
beneath the 1/2" basket strainer inside the float tank.
By injecting compressed air, all water will be blown out
of the system.
Adjustable Thermostat
For safety, each machine is equipped with an adjust
-
able thermostat. In the event that the temperature of
the water should exceed its operating temperature, the
thermostat will turn the burner off until the water cools.
Pumps
Use only SAE 10W-40 weight 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 using dipstick found on top of pump or by
checking red dot visible through oil gauge window. Oil
should be maintained at that level.
Cleaning of Coils
In alkaline water areas, lime deposits can accumulate
rapidly inside coil pipes. This growth is increased by
extreme heat build up in the coil. The best prevention
for liming conditions is to use high quality cleaning
chemicals. 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 the coil becomes plugged.
Periodic descaling of heating coils is recom

mended so please consult your local Landa Dealer
for instructions.
