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.
This machine can siphon and mix
detergents with the use of Landa's
detergent injector kit.
1. Pull injector quick coupler collar back and secure on
discharge nipple by pushing collar forward. Injector
valve body arrow should point in direction of flow.
2. Connect high pressure hose to injector nipple se-
curing quick coupler.
3. Start machine as outlined in Operating Instructions.
4. Place detergent pick-up tube into container of deter-
gent solution.
5. Turn variable pressure control handle counterclock-
wise to lower pressure and divert water flow through
the soap nozzle.
6. Pull trigger on spray gun. Water detergent ratio is
approximately 15 to 1.
7. When you finish washing, rinse by simply turning vari-
able pressure control handle clockwise.
NOTE: The detergent injector will not siphon with wa-
ter flowing through the high pressure nozzle at end
of wand.
8. For clean up, place detergent pick-up tube into con-
tainer of clear water and follow steps 5 - 8 to prevent
detergent deposits from damaging the injector.

GENERAL
WASHING TECHNIQUES
1. Hold spray nozzle approximately one foot from the
surface being cleaned. Spray at an angle to get un-
der the material and lift it off.
2. When washing large objects, use detergent injector
to apply detergent (see section “How to Use the De-
tergent Injector”).Start washing from the bottom and
work up. Better detergent economy and faster re-
sults will be obtained by allowing the detergent to
set 5-10 minutes. After washing, rinse from the top
down.
3. Cleaning heavy dirt or material away with a hard
stream of clear water is recommended before using
a cleaning agent.
MAINTENANCE
Pump Lubrication
LANDA PUMPS: The pump on your Landa Pressure
Washer is a triplex ceramic plunger pump. As the plung-
ers move back, water flows through the inlet valve into
the manifold chamber. Then, when the plungers move
forward, the inlet valves close and the discharge valves
open to produce discharge pressure.
Use only Landa SAE 30 weight non-detergent oil; change
oil after first 50 hours of use. Thereafter, change oil at
three months or 500 hour intervals. Oil level should be
checked through the use of the dipstick found on top of
the pump, or half way up on the oil gauge window. Oil
should be maintained at that level.
Unloader Valves
The unloader valve is connected directly to the discharge
port of the pump. Its purpose is to allow recirculation
back into the pump inlet when the trigger on the spray
gun is closed.
Nozzles
Each machine is equipped with one spray nozzle de-
pending on the flow and pressure of that particular model.
Spray nozzles vary in bore size and angle of spray. When
ordering replacement nozzles, please specify size and
angle of nozzle. Nozzle size for each machine is located
on the serial plate.
Winterizing Procedure
Damage due to freezing is not covered by warranty. Use
the following cold weather procedures whenever the
washer must be stored or operated outdoors under freez-
ing conditions.
During winter months, when the temperature drops be-
low 32°F, it is necessary to protect your machine against
freezing. A blowout valve, which can be screwed into
the garden hose swivel connecter to blow water out of
the system, is available from Landa. When compressed
air is not available or is impractical, siphon a 50/50 mix-
ture of anti-freeze into the pump by using a bucket with
a short section of garden hose attached to the bottom,
then elevate. Run the pump dry for a few seconds and
disconnect all hoses to allow water to drain.
Low Pressure Diagnosis
Refer to Troubleshooting Chart for low pressure. If, by
referring to the chart, the trouble is found to be either the
unloader or the pump, your next step is to determine
whether in fact the unloader or the pump is the problem.
This can be done by eliminating the unloader from the
system and attaching the discharge hose directly to the
pump. If high pressure is developed in this manner the
pump is good and the unloader needs to be repaired or
replaced. If low pressure is developed in this manner,
the pump is good, and the unloader needs to be repaired
or replaced. If low pressure is still present, the pump
needs repairing.
CAUTION: When using this procedure to test com-
ponents, keep the spray gun trigger open at all times.
TIME DELAY SHUTDOWN
OPERATION
Once the spray gun trigger is released, the shutdown timer
becomes activated. The machine will continue to run in
by-pass mode until the timer reaches its preset time, 1-10
minutes. When that time is reached, the machine shuts
down. To reset, push the pump switch forward.
