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 Check the water inlet strainer to ensure it is clean and free of any
obstructions. As a strainer becomes obstructed, it restricts proper ow of
water to the pump. This can result in cavitations which will prematurely
cause failure of pump packings.
a. Unscrew the strainer cap from the unit.
b. Remove the 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: When connecting the water inlet to the water supply mains, local
regulations of your water company must be observed. In some
areas, the unit must not be connected directly to the public drinking
water supply. This is to ensure there is no feedback of detergents
into the water supply. (Direct connection is permitted if a backow
preventer is installed. Check with local authorities for approval.)
NOTE: If the mineral content of the water in your area is extremely high, the
use of a water softener is recommended 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 a minimum of 20 pounds per square inch
(PSI) and a maximum of 125 PSI. (A typical outdoor faucet will
generally supply this PSI if turned completely "ON".)
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 ll 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 is completely turned on.

CAUTION
RISK OF UNIT DAMAGE!
DO NOT OVERTIGHTEN THE
UNLOADER. BREAKAGE COULD
RESULT IN IMMEDIATE LOSS OF
WATER PRESSURE AND COSTLY
REPAIRS.
INSTALLATION & PREPARATION
UNLOADER:
The unloader on these models is not equipped with an adjustment knob. DO
NOT adjust pressure on your own. The pressure has been preset at the factory
and should only be adjusted by a trained Service Representative.
THERMAL RELIEVE VALVE:
To ensure the water temperature does not exceed acceptable levels, never allow
the pressure washer to operate in the bypass mode (with the unit running and
the trigger closed) for more than three minutes.
A thermal relieve valve has been added to this unit to protect the pump. It may
begin to open and release water if the water temperature in the pump has exceeded
140° F. This will allow fresh, cool water to enter the system, therefore preventing
premature failure of pump packings.
PRE-START INSPECTION PROCEDURES:
Before starting the unit, perform the following procedures:
1. Check the oil level in the pump and engine.
2. Inspect the water inlet strainer. Clean or replace if necessary. See "Water
Supply", #2, pg 13.
3. Check all hose connections to ensure they are securely tightened. See
"Water Supply", #3, pg. 13.
4. Inspect for system water leaks, oil leaks and fuel leaks. If a fuel leak is
found, DO NOT START UNIT! See "Risk of Explosion or Fire", pg. 4. 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.
5. Inspect high pressure hoses for kinking, cuts and leaks. If a cut or leak is
found, DO NOT USE HOSE! Replace hose before starting unit. See "Risk
of Injection" 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.

IN COSTLY REPAIRS.
OPERATING INSTRUCTIONS
PRIMING THE PUMP:
It is essential to prime the pump and ush the unit each time the water supply
has been disconnected from the unit OR whenever the unit has set for any
period of time. This unit has a steel coil which, after setting, will cause the
water remaining in the coil from the previous usage to turn brown or black.
This contaminated water must be ushed from the system before start-up. This
procedure should be performed without the high pressure hose, gun and dual
lance assembly installed.
DIRECT FEED: All units.
1. Turn on the water supply.
2. Low pressure water will begin owing from the water outlet. This allows the
unit to prime and purge any air from the system. The unit is primed when
water ow is uninterrupted by air.
3. Once the unit is primed, turn off the water supply and connect the high
pressure discharge hose to the water outlet of the unit. (Note: The trigger
gun and dual lance assembly should already be connected to the high
pressure discharge hose at this time.)
4. Turn on the water supply.
SUCTION FEED: These models have the ability to draw water from a static source
and can provide a suction lift of 5' with a 3/4" inlet hose. We recommend
the following for suction feed.
1. Immerse a 3/4" x 5' long inlet hose into the water supply.
2. Start the engine following the start up procedures given in the engine manual
accompanying this unit.
3. Adjust the engine to a low speed until you see water exiting the water
outlet.
NOTE: This may take up to 3-5 minutes. Adjust the engine throttle back to
full RPM.
4. Once the unit is primed, stop the engine and connect the high pressure
discharge hose to the water outlet of the unit.
NOTE: The trigger gun and dual lance assembly should already be connected
to the high pressure discharge hose at this time.

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 the burner switch is in the "OFF" position.
4. Pointing the trigger gun in a safe direction, unlock the trigger gun and squeeze
the trigger. Hold the trigger gun open while starting the engine according
to the manufacture's instructions in the engine manual accompanying this
unit.
5. Once the engine has started, ensure the engine throttle is adjusted to full
RPM and perform the following procedures with the trigger 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 Fire",
pg. 4. 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, cuts 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", 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.
6. At this point, the unit is operating as a cold water pressure washer. Trigger
the gun several times and try adjusting the water pressure. NEVER place
hand or ngers in front of the nozzle or look directly into the nozzle! High
pressure water creates a risk of severe injury!
7. 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.
8. 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 application or
Cleaning with Detergents, see page 17 for the correct procedures.
OPERATING INSTRUCTIONS
HOT WATER OPERATION:
1. Follow the steps outlined for "START-UP/COLD WATER OPERATION".
2. Move the Burner Switch to the ON 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 ring when the trigger is released.
NOTE: While spraying, it is normal for the burner to re intermittently. The
high-limit switch will cause combustion to cease when the temperature
of the discharged water exceeds the maximum temperature setting of
the switch. Combustion will begin again when the temperature drops
below the minimum setting.
At this point, the unit is operating as a hot water pressure washer. Be certain to
be extremely cautious when adjusting the pressure and controlling the trigger
gun/dual lance assembly to avoid the possibility of burns.
CLEANING WITH DETERGENTS UNDER LOW PRESSURE:
NOTE: This feature is designed for use with mild detergents only. Since the
cleaning solution travels through the heat exchanger coil, 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 uids or solvents through the unit. Due to the unknown
and often corrosives characteristics of many detergents commonly used in
the pressure washer cleaning industry, it is recommended to use only John
Deere 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 by locating the adjustment knob at
the end of the clear vinyl hose. Turn the knob completely counterclockwise to
set at maximum siphon rate. Be certain the adjustable grip on the dual lance
is turned completely clockwise for low pressure detergent operation.
NOTE: This injection system is designed to apply detergents under low pressure
only. It will not allow detergent solutions to be introduced into the system
unless the dual lance is set in the low pressure mode.
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 briey. 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 clean a small section at a time.
6. To rinse; lock the trigger gun in the "OFF" position, rotate the adjustable
grip on the dual lance counterclockwise for high pressure. 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 low pressure detergent injection system
after each use. This prevents the possibility of corrosion or detergent residue
causing mechanical problems during the next use.
