IMPORTANT SAFETY
INFORMATION
CAUTION: To reduce the risk of
injury, read operating instruc-
tions carefully before using
1. Read the owner's manual thor-
oughly. Failure to follow instruc-
tions could cause malfunction
of the machine and result in
death, serious bodily injury and/
or property damage.
2. Know how to stop the machine and bleed pressures
quickly. Be thoroughly familiar with the controls.
3. Stay alert — watch what you are doing.
4. All installations must comply with local codes. Con-
tact your electrician, plumber, utility company or the
selling distributor for specific details.
To comply with the National Electrical code (NFPA
70) and provide additional protection from risk of elec-
tric shock, these pressure washers are equipped with
a UL approved ground fault circuit interrupter on 230
single phases and smaller.
WARNING: Flammable liquids
can create fumes which can ig-
nite causing property damage or
severe injury.
WARNING: Risk of explosion —
do not spray flammable liquids.
5. Risk of explosion - do not spray
flammable liquids or operate in
an explosive location.
WARNING: Keep water spray
away from electrical wiring or fa-
tal electrical shock may result.
6. To protect the operator from
electrical shock, the machine
must be electrically grounded.
It is the responsibility of the
owner to connect this machine
to a UL grounded receptacle of
proper voltage and amperage ratings. Do not spray
water on or near electrical components. Do not touch
machine with wet hands or while standing in water.
Always disconnect power before servicing.
7. Grip cleaning wand securely with both hands before
starting the cleaner. Failure to do this could result in
injury from a whipping wand.
WARNING: High pressure stream
of fluid that this equipment can
produce can pierce skin and its un-
derlying tissues,leading to serious
injury and possible amputation.
8. High pressure developed by
these machines will cause per-
sonal injury or equipment dam-
age. Use caution when operat-
ing. Do not direct discharge stream at people, or se-
vere injury or death will result.
9. Never make adjustments on machine while it is in
operation.
WARNING: High pressure spray
can cause paint chips or other
particles to become airborne and
fly at high speeds.
10. Eye safety devices and foot pro-
tection must be worn when us-
ing this equipment.

PRE-OPERATION CHECK
❏ Pump oil (SAE 30W non-detergent oil)
❏Cold water supply (6 gpm •5/8" •20 psi)
❏Hose, wand, nozzle (nozzle size per serial plate)
❏Water filter (intact, non restrictive)
SET-UP PROCEDURES
These machines are designed for indoor use. Ma-
chine must be stored indoors when not in use.
1. Attach a 5/8" garden hose to inlet connector. Mini-
mum flow should be 6 gpm.
2. Attach high pressure hose to discharge nipple using
quick coupler. Lock coupler securely into place by
pulling back coupler collar and inserting it onto dis-
charge nipple, then pushing collar forward to lock in
place.
3. Attach wand to spray gun using teflon tape on threads
to prevent leakage.
4. Attach swivel connector on discharge hose to spray
gun using teflon tape on threads.
5. Remove red oil plug on top of pressure washer pump
and replace with oil dipstick supplied.
6. Check oil level on sight glass on side of pressure
washer pump. Oil should be visible one-half way up
sight glass. (Use 30 wt. non-detergent oil only.)
7. On 230V and 460V machines, attach appropriate
plug end (not included) to power cord.
OPERATING INSTRUCTIONS
1. With power switch in OFF position, plug power cord
into a grounded type of receptacle of proper voltage
and amperage reading. Then push GFCI reset but-
ton at end of power cord if required.
2. Turn on water at faucet and pull trigger on spray gun
allowing water to flow until all air has discharged from
system. Check for water leaks; tighten as needed.
3. Pull wand coupler collar back and insert pressure
nozzle into coupler then secure by pushing collar
forward.
4. With spray gun off, push green start switch/toggle
switch to ON position and check for leaks.
5. With spray nozzle pointed away from you or any-
body else, press trigger on spray gun to obtain pres-
surized spray.
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.
SHUT DOWN PROCEDURES
1. Rinse all lines (and injector) with clean water, to re-
move any soap residue.
2. Turn motor off.
3. Push red stop switch/toggle switch to OFF position.
4. Open spray gun to relieve remaining pressure.
5. Remove water supply hose.
6. In freezing conditions, disconnect water supply and
open spray gun to allow water to drain, then turn off
motor.
CAUTION: Do not allow pump to run longer than 5
minutes without water. Disconnect all hoses to al-
low water to drain.
CAUTION: With machine off, open spray gun to re-
lease pressure before removing discharge hose.

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. Pull injector quick coupler collar back and secure on
discharge nipple. 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. Install the brass soap nozzle provided with the in-
jector into the quick coupler of the wand.
6. Open spray gun. Water detergent ratio is approxi-
mately 15 to 1.
7. 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.
8. 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.
9. 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.
