WATER SUPPLY:
1. Select a water supply hose which is a quality grade of garden hose measuring
at least 3/4" ID and no longer than 50 feet.
2. If your unit is equipped with a water strainer, ensure it is clean and free of
any obstructions. Periodic cleaning of the water strainer will help prevent
pump problems. As a strainer becomes obstructed, it restricts proper flow of
water to the pump. This can result in cavitation which will cause premature
failure of pump packings.
a. Unscrew the strainer bowl from the unit.
b. Remove strainer screen and clean or replace.
3. Connect one end of the water supply hose to the water inlet of the unit.
Connect the other end of the hose to your pressurized water supply.
NOTE: If there is a high mineral content in your water, it is recommended that
a water softener be used to prevent the possibility of excessive scale
buildup inside the heat exchanger coil.
4. Follow the incoming water requirements listed below:
a. Water pressure must be between a minimum of 20 pounds per square
inch (PSI) and a maximum of 125 PSI.
b. Incoming GPM must be approximately one gallon more than the outgoing
GPM stated on the pressure washer nameplate. (You can check GPM
by timing how long it takes to fill a 5 gallon container.)
c. Incoming water temperature must not exceed 125°F. Excessive pump
damage may result if the water temperature exceeds this acceptable
level.
5. Never allow the unit to operate without the incoming water line attached and
the water supply completely turned on.

2. Move the switch to the "Pump" position. Low pressure water will begin
flowing from the water outlet. This allows the unit to flush any particles from
the system. The unit is flushed when the water is clear.
3. Once the system is flushed, move the switch to the "OFF" position and
connect the high pressure hose to the water outlet of the unit.
4. Connect the trigger gun and dual lance assembly to the high
pressure hose.
START-UP/COLD WATER OPERATION:
CAUTION
RISK OF UNIT DAMAGE.
BE CERTAIN THE HOSE, GUN
& DUAL LANCE ASSY. ARE
NOT CONNECTED TO T H E
UNIT WHILE FLUSHING THE
SYSTEM. FLUSHING ALLOWS
MINERAL DEPOSITS TO BE
RELEASED FROM THE SYSTEM
WHICH WOULD OBSTRUCT
OR DAMAGE THE GUN AND
NOZZLE ASSEMBLY RESULTING
IN COSTLY REPAIRS.
1. Refer to the "Safety Precautions" pgs. 4-7 before starting the unit.
2. Locate the Safety Decals on your unit and heed their warnings.
3. Ensure that the switch is in the "OFF" position.
4. Pointing the trigger gun in a safe direction, unlock the trigger gun and
squeeze the trigger. Brace yourself for possible gun kickback when the
pump starts.
5. Move the switch to the "Pump" position.
6. Once the unit has started, perform the following procedures with the gun
open:
a. Inspect for system water leaks, oil leaks and fuel leaks.
If a fuel leak is found, TURN UNIT OFF IMMEDIATELY! See "Risk of
Explosion or Fire", pg. 5. Be sure that all damaged parts are replaced
and that the mechanical problems are corrected prior to operation of
the unit. If you require service, contact Customer Service.
b. Inspect high pressure hoses for kinking, cu ts and leaks.
If a cut or leak is found, DO NOT TOUCH HOSE AT LEAK!!! TURN UNIT
OFF IMMEDIATELY! Replace hose before starting the unit. See "Risk
of Injection or Severe Cutting Injury" pg. 6. Be sure that all damaged
parts are replaced and that the mechanical problems are corrected
prior to operation of the unit. If you require service, contact Customer
Service.
7. At this point, the unit is operating as a cold water pressure washer. Trigger
the gun several times and try adjusting the water pressure by rotating the
grip on the dual lance. NEVER place hand or fingers in front of the nozzle
or look directly into the nozzle! High pressure water creates a risk of severe
injury!
8. Do not allow unit to operate in bypass mode (with trigger closed) for more
than three minutes without triggering the gun. Failure to follow this simple
rule can cause premature failure of pump packings, resulting in costly pump
repair.
NOTE: If this unit is equipped with an Auto Start/Stop feature, the pressure
washer will shutdown if the gun is not triggered after a designated
amount of time. The pressure washer will start again once the gun
is triggered. The Auto Start/Stop feature is preset at the factory for
shutdown at 90 seconds. It can be adjusted by an Authorized Service
Technician to shutdown from no usage after a minimum of 3 seconds
to a maximum of 5 minutes.
9. Your pressure washer can deliver high pressure spray and a variety of spray
patterns using cold water. If you wish to use the Hot Water, Steam application
or Cleaning with Detergents, see page 18 for the correct procedures.

OPERATING INSTRUCTIONS
HOT WATER OPERATION:
1. Follow the steps 1-8 outlined for "START-UP/COLD WATER
OPERATION".
2. Move the switch to the "Burner" position. On initial start-up, water will
begin turning hot in approximately 20 seconds and will reach maximum
temperature in approximately 2-1/2 minutes, provided the trigger remains
squeezed. The burner will stop firing when the trigger is released.
NOTE: While spraying, it is normal for the burner to fire intermittently. The
high limit switch will cause combustion to cease when the temperature
of the discharged water exceeds the temperature setting of the switch.
Combustion will begin again when the water temperature drops below
the minimum setting .
At this point, the unit is operating as a hot water pressure washer. Be
extremely cautious when adjusting the pressure and controlling the
trigger gun/dual lance assembly to avoid the possibility of burns.
STEAM OPERATION:
1. Follow steps 1-8 outlined for "STARTUP/COLD WATER OPERATION".
2. Ensure the quick-connect at the end of the dual lance is cool enough to
touch, then remove the high pressure nozzle and replace it with the steam
nozzle. Remove the high pressure hose and replace it with the steam
hose.
3. Turn unloader knob completely counterclockwise to the minimum setting.
4. Turn the switch to "Steam".
NOTE: The burner will shut down if the switch is moved to "Steam" without
first setting the unloader to minimum or operating in the high pressure
mode.)
At this point, the unit will operate as a steam pressure washer. Be
extremely cautious when adjusting the pressure and controlling the
trigger gun/dual lance assembly to avoid the possibility of burns.
CLEANING WITH DETERGENTS:
NOTE: This feature is designed for use with mild detergents only. Since the
cleaning solution travels through various parts of the pressure washer,
do not use corrosives as they will cause extensive damage as well as
pose a considerable safety hazard.
1. Refer to "Risk of Bodily Injury / Detergents" pg. 7. Be certain to wear
protective safety attire as stated on pg. 12.
2. Prepare detergent solution according to label directions. (Never pump acids,
alkalines, abrasive fluids or solvents through the unit. Due to the unknown
DETERGENT METERING VALVE
18 John Deere Operator's Manual
and often corrosive characteristics of many detergents commonly used in
the pressure washer cleaning industry, it is recommended to use only mild
detergents with this unit.)
3. Fully immerse the strainer end of the clear vinyl detergent hose into the
detergent solution.
4. Adjust the amount of detergent desired. Turn the metering valve completely
counterclockwise to set at maximum siphon rate.
5. To apply solution; unlock the trigger gun and squeeze the trigger. In a few
moments a detergent/water mixture will exit the nozzle. Start spraying
the lower portion of the surface being cleaned and move up, using long
overlapping strokes. Applying from the bottom up helps avoid streaking.
Allow to soak briefly. Avoid working on hot surfaces or in direct sunlight to
minimize the chances of the detergent drying, which may result in damaging
surfaces. Be certain to apply cleaning solution to a small section at a
time.
6. To rinse; lock the trigger gun in the "OFF" position, turn the detergent
metering valve to the "OFF" position. Unlock the trigger gun and spray. It
will take about 30 seconds to purge all detergent from the line. For best
rinsing results, start at the top and work down.
7. Siphon a gallon of water through the detergent injection system after each
use. This prevents the possibility of corrosion or detergent residue causing
mechanical problems during the next use.
