GENERAL
WASHING TECHNIQUES
❑Test pressure and spray pattern on hard surface (i.e.
cement) to gauge distance and impact of water spray.
❑Hold spray nozzle approximately one foot from sur-
face being cleaned. For best surface cleaning ac-
tion, spray at slight angle.
❑To change spray nozzle for a different pattern it is
recommended that you turn off machine and
squeeze spray gun trigger to release hose pressure.
Pull back on quick coupler at end of wand and ex-
change nozzle. Make sure nozzle is seated securely.
Restart machine.
❑Use the detergent injector to apply detergent. Wash
from the bottom and work up. Allow the detergent to
set 5-10 minutes on surface. Rinse from top down.

HOW TO USE THE
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. Turn off machine and water supply. Squeeze spray
gun to relieve pressure before attaching detergent
injector.
2. Pull injector quick coupler collar back and secure on
discharge nipple. Injector valve body arrow should
point in direction of flow.
3. Connect high pressure hose to injector nipple se-
curing quick coupler.
4. Start machine as outlined in Operating Instructions.
5. Place detergent pick-up tube into container of deter-
gent solution.
6. Install the brass soap nozzle provided with the in-
jector into the quick coupler of the wand.
7. Open spray gun. Water detergent ratio is approxi-
mately 15 to 1.
8. When you finish washing, rinse by simply releasing
the spray gun, removing the soap nozzle, and re-
placing the pressure nozzle back into quick coupler.
NOTE: The detergent injector will not siphon with
the high pressure nozzle at the end of the wand.
9. If your machine has a variable pressure wand, turn
the pressure control handle counterclockwise to
lower the pressure by directing the water flow through
the soap nozzle which allows the detergent injector
to siphon soap. To rinse with high pressure water,
simply turn the control handle clockwise.
10. For clean up, place detergent pick-up tube into con-
tainer of clear water and follow steps 5 and 8 to pre-
vent detergent deposits from damaging the injector.

PREVENTATIVE MAINTENANCE
This pressure washer was produced with the best available materials and quality craftsmanship. However, you as the
owner have certain responsibilities for the correct care of the equipment. Attention to regular preventative mainte-
nance procedures will assist in preserving the performance of your equipment. Contact your Landa, Inc. dealer for
maintenance. Regular preventative maintenance will add many hours to the life of your pressure washer. Perform
maintenance more often under severe conditions.
Pump Oil
Inspect Daily inspect the oil level
Change After first 50 hours, then every 500 hours or annually
Replace High Pressure Nozzle Every 6 months
Replace Quick Connects Anually
Clean Water Screen/Filter Weekly
Replace HP Hose Anually if there is any sign of wear
Grease Motor Every 10,000 hours or annually
General InspectionInspect the motor at regular intervals, approximately every 500 hours of operation, or
every 3 months, whichever occurs first. Keep the motor clean and the ventilation open-
ings clear.The following steps should be performed at each inspection:
WARNING: Do not touch electrical connections before you first ensure that power has
been disconnected. Electrical shock can cause serious or fatal injury. Only qualified
personnel should attempt the installation, operation and maintenance of this equipment.
1. Check that the motor is clean. Check that the interior and exterior of the motor is
free of dirt, oil, grease, water, etc. Oily vapor, paper pulp, textile lint, etc. can
accumulate and block motor ventilation. If the motor is not properly ventilated
overheating can occur and cause early motor failure.
2. Check all electrical connectors to be sure that they are tight.
Lubrication & Bearings Bearing grease will lose its lubricating ability over time, not suddenly. The lubricating ability
of a grease (over time) depends primarily on the type of grease, the size of the bearing,
the speed at which the bearing operates and the severity of the operating conditions.
Good results can be obtained if the following recommendations are used in your mainte-
nance program.
Type of Grease A high grade ball or roller bearing grease should be used. Recommended greases stan-
dard service conditions are:
Shell Dolium R (Factory installed) or Chevron SRI
