GENERAL WASHING
TECHNIQUES
Hold spray nozzle approximately one foot from the sur-
face being cleaned. Spray at an angle to get under the
material and lift it off.
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.
Cleaning heavy dirt or material away with a hard stream
of clear water is recommended before using a cleaning
agent.

SHUTDOWN PROCEDURES

residue.
2. Turn burner switch off and continue spraying, allow-
ing the water to cool below 100°.
3. To stop engine simply turn key to OFF position.
4. Turn off water supply.
5. Open spray gun to relieve remaining pressure.
6. Remove water supply hose.
7. In freezing conditions, disconnect water supply and
open spray gun to allow water to drain; then turn off
engine. See winterizing procedure under Mainte-
nance and Service.
CAUTION: Do not allow pump to run longer than
5 minutes without water. Disconnect all hoses to al-
low water to drain.
With machine off, open spray gun to release pres-
sure before removing discharge hose.
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 Landa cleaning prod-
ucts.
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 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 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.
