Component Identification
Detergent Injector - Allows you to siphon and mix
detergents, when the variable pressure control handle
is turned to low pressure.
High Pressure Hose — Connect one end to water
pump discharge nipple and the other end to spray gun.
Spray Gun — Controls the application of water and
detergent onto cleaning surface with trigger device.
Includes safety latch.
Wand — Must be connected to the spray gun.
Swivel Connector - Allows free range of movement to
avoid coiling hoses.
NOTE: If trigger on spray gun is released for more
than 2 minutes, water will leak from pump
protector valve. Warm water will discharge onto
floor and cool water will allow the pump protector
to seal. This system prevents internal pump
damage.

Assembly Instructions
STEP 1: Attach the high pressure
hose to the spray gun using teflon
tape on hose threads. Use safety
latch to prevent from opening.
STEP 2: Connect garden hose to
the cold water source. Before
installing nozzle, turn on water
supply and run machine, allowing
water to flush through the system
until clear.
STEP 3: Insert nozzle into coupler.
Release the coupler collar and
push the nozzle until the collar
clicks. Pull the nozzle to make sure
it is seated properly.
Landa SEA MS Operator’s Manual 9.801-720.0 - AJ
STEP 4: Connect the high pressure hose to the outlet
discharge fitting. Push coupler collar forward until
secure. Connect the garden hose to pump water inlet.
Inspect inlets.
CAUTION: Do not run the pump without water or
pump damage will result.
ATTENTION: Ne pas faire fonctionner la pompe sans
eau pour éviter d'endommager la pompe.

10
Operating Instructions
STEP 1: Connect garden hose to
the cold water source and turn
water on completely. Never use hot
water.
STEP 4: Turn machine on by
pushing switch at front of machine.
STEP 2: Trigger the spray gun to
eliminate trapped air then wait for a
steady flow of water to emerge
from the spray wand. Then install
nozzle.
STEP 3: Connect to appropriate
power supply. Push GFCI reset
button.
WARNING! Never replace
nozzles without engaging the
safety latch on the spray gun
trigger.
AVERTISSEMENT: Ne jamais
remplacer les buses sans
d'abord mettre le dispositif de
sécurité sur la détente du
pistolet pulvérisateur.
Landa SEA MS Operator’s Manual 9.801-720.0 - AJ
The five color-coded quick connect nozzles provide a wide array of spray
widths from 0° to 40° and are easily accessible when placed in the conve-
nient rubber nozzle holder, which is provided on the front of the machine.
NOTE: For a more gentle rinse, select the white 40° or green 25° nozzle.
To scour the surface, select the yellow 15° or red 0° nozzle.

11
Detergents And General
Operating Techniques
WARNING: Some detergents may
be harmful if inhaled or ingested,
causing severe nausea, fainting or
poisoning. The harmful elements
may cause property damage or
severe injury.
AVERTISSEMENT: Certains
détergents peuvent être dangereux
s'ils sont inhalés ou ingérés,
provoquant de fortes nausées, des
évanouissements et l'empoisonnement. Les
éléments dangereux peuvent causer des dommages
à la propriété ou des blessures graves.
STEP 1: Use detergent designed
specifically for pressure washers.
Household detergents could damage
the pump. Prepare detergent solution
as required by the manufacturer. Fill a
container with pressure washer deter-
gent. Place the filter end of detergent
suction tube into the detergent
container.
STEP 2: Apply safety latch to spray
gun trigger. Turn variable pressure
control handle counter clockwise to
low pressure.
NOTE: Detergent cannot be
applied using the Yellow nozzle.
STEP 3: With the engine running, pull trigger to operate
machine. Liquid detergent is drawn into the machine and
mixed with water. Apply detergent to work area. Do not
allow detergent to dry on surface.
IMPORTANT: You must flush the detergent injection
system after each use by placing the suction tube
into a bucket of clean water, then run the pressure
washer in low pressure for 1-2 minutes.
Thermal Pump Protection
If you run your pressure washer for 2 minutes without
pressing the trigger on the spray gun, circulating water in
the pump can reach high temperatures. When the water
reaches this temperature, the pump protector engages
and cools the pump by discharging the warm water onto
the ground. This thermal device prevents internal
damage to the pump.
Cleaning Tips
Pre-rinse cleaning surface with fresh water. Place
detergent suction tube directly into cleaning solution and
apply to surface at low pressure (for best results, limit
your work area to sections approximately 6’ square and
always apply detergent from bottom to top). Allow
detergent to remain on surface 1-3 minutes. Do not allow
detergent to dry on surface. If surface appears to be
drying, simply wet down surface with fresh water. If
needed, use brush to remove stubborn dirt. Rinse at high
pressure from top to bottom in an even sweeping motion
keeping the spray nozzle approximately 1’ from cleaning
surface. Use overlapping strokes as you clean and rinse
any surface. For best surface cleaning action spray at a
slight angle.
Recommendations:
• Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
distance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use
extreme caution as pressure washer may
remove the loose paint from the surface.
• Keep the spray nozzle a safe distance from the
surface you plan to clean. High pressure wash a
small area, then check the surface for damage. If
no damage is found, continue to pressure
washing.
CAUTION - Never use:
• Bleach, chlorine or other corrosive chemicals
• Liquids containing solvents (i.e., paint thinner,
gasoline, oils)
• Tri-sodium phosphate products
• Ammonia products or acid-based products
ATTENTION: Ne jamais utiliser :
• Eau de Javel, produits à base de chlore et
autres produits chimiques corrosifs
• Liquides contenant des solvants (c.-à-d. diluant
à peinture, essence, huiles, etc.)
• Produits à base de tripolyphosphate de sodium
• Ammoniac ou produits à base d'acide
These chemicals will harm the machine and will damage
the surface being cleaned.

Shutting Down And
Clean-Up
STEP 1: Remove
detergent suction tube
from soap container and
insert into one gallon of
fresh water.Turn variable
pressure control handle
to low pressure with
detergent injector. Pull
trigger on spray gun and
siphon water for one
minute.
STEP 2: Turn off
machine by pushing
switch on front panel.
STEP 3: Turn off water
supply.
STEP 4: Press trigger to
release water pressure.
STEP 7: Engage the
spray gun safety lock.
Landa SEA MS Operator’s Manual 9.801-720.0 - AJ
STEP 5: Disconnect the garden hose
from the water inlet on the machine.
Protect from freezing.
STEP 6: Disconnect the high pressure
hose from high pressure outlet.
Rinsing
It will take a few seconds for the detergent to clear. Apply safety latch to spray gun. Remove black soap nozzle from
the quick coupler. Select and install the desired high pressure nozzle.
NOTE: You can also stop detergent from flowing by simply removing detergent siphon tube from bottle.

13
Storage
Pump Storage
CAUTION: Always store your pressure washer in a location where the temperature will not fall
below 32° F (0° C). The pump in this machine is susceptible to permanent damage if frozen.
FREEZE DAMAGE IS NOT COVERED BY WARRANTY.
ATTENTION: Toujours entreposer la laveuse à pression dans un endroit où la température ne sera
pas inférieure à 32°C (0 °F). La pompe sur cette machine est susceptible de subir des dommages si
elle est exposée au gel.
LES DOMMAGES DUS AU GEL NE SONT PAS COUVERTS PAR LA GARANTIE.
If you must store your pressure washer in a location where the temperature is below 32° F, you can minimize the
chance of damage to your machine by draining your machine as follows:
1. Stop the pressure washer and detach supply hose and high pressure hose. Squeeze the trigger of the spray
gun to drain all water from the wand and hose.
2. Restart pressure washer and let it run briefly (about 5 seconds) until water no longer discharges from the high
pressure outlet.
