NOZZLE REVIEW

WARNING: RISK OF INJECTION CAUSING SEVERE INJURY!

NEVER LOOK DIRECTLY AT THE NOZZLE ORIFICE UNLESS IT IS DISCONNECTED FROM THE GUN/WAND ASSEMBLY!

Various nozzles may be quick-connected into the end of the wand to change the spray pattern or use the detergent feature. When using Quick Connects (Q.C.), be certain the connection is securely locked. If not, the high pressure water may shoot the nozzle from the wand, causing severe injury or serious damage. To determine spray fan, refer to the actual number stamped on the nozzle. The ﬁrst two digits indicate the spray fan in degrees, i.e.; 00=0”, 15=15°, 25=25°, 65=detergent/low pressure.

1. The 0” nozzle (RED): This is a blasting nozzle. It delivers a very concentrated stream of water. Be cautious when using the straight narrow stream. It is not recommended for use on painted or wood surfaces, or items attached with adhesive backings. Uses: Removing weeds from sidewalk cracks, stubborn stains from concrete, masonry, aluminum and steel, caked mud from equipment, and cleaning lawn mower undersides.

2. The 15° nozzle (YELLOW): This is a chiseling nozzle. The spray should be directed at a 45° angle to the surface and used like a scraper to remove paint, grease and dirt. Uses: Surface preparation (removing mildew stains and paint chips).

3. The 25° nozzle (GREEN): This is a ﬂushing nozzle. This pattern is best suited for ﬂushing dirt, mud, and grime. Uses: Wet sweeping leaves from walks, curbs and driveways, cleaning stable ﬂoors, washing swimming pool bottoms, degreasing engines.

4. The 65° nozzle (BLACK): This is a low pressure detergent application nozzle. This broad spray pattern distributes solution over vast areas under low pressure. Uses: Detergent application, misting or rinsing.

NOZZLE CONNECTION

WARNING: RISK OF SEVERE INJURY! THE TRIGGER GUN SHOULD ALWAYS BE LOCKED IN THE OFF POSITION WHEN NOT IN USE!

1. Be certain the trigger gun is locked in the "OFF"

position.

2. The nozzle assembly should be disconnected from the gun/wand assembly at this by retracting the locking ring on the quick-connect ﬁtting to remove the nozzle.

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. 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 cavitations which will cause premature failure of pump packings and valves. Using a screw driver, remove the screen; clean or replace if necessary.

3. Connect the hoses. a. Connect one end of the water supply hose to the water inlet

of the unit.

b. Connect the other end of the hose to your pressurized water

supply.

NOTE: Do not use a non-pressurized water supply (i.e. from a

well or pond) with this unit.

c. Connect the high pressure discharge hose to the water outlet

of the unit.

4. Follow the incoming water requirements listed below: a. Water pressure must be a minimum of 25 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 ﬁll a 5 gallon container.

c. Incoming water temperature must not exceed 125°F (52°C).

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 turned all the way on.

UNLOADER

The unloader valve on your machine is equipped with an adjustment knob to adjust the pressure. Should less pressure be required, simply turn the adjustment knob counterclockwise. To set back to maximum, turn adjustment knob completely clockwise. DO NOT OVERTIGHTEN!

CAUTION THE UNLOADER. BREAKAGE WILL RESULT IN IMMEDIATE LOSS OF WATER PRESSURE AND COSTLY REPAIRS.

: RISK OF UNIT DAMAGE! DO NOT OVERTIGHTEN

THERMAL RELIEF VALVE

To ensure the bypass 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 relief 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.

2. Inspect the inlet water strainer. Clean or replace if necessary. See "Water Supply".

3. Check all hose connections to ensure they are securely tightened. See "Water Supply".

4. Inspect for system water leaks and oil leaks. Be sure that all damaged parts are replaced and that the mechanical problems are corrected prior to operation of the unit. If service is needed, contact Customer Service.

5. Inspect high pressure hose for kinking, cuts or leaks. If a cut or leak is found, DO NOT USE HOSE! Replace hose before starting unit. See "Miscellaneous Safety Precautions". Be sure that all damaged parts are replaced and that the mechanical problems are corrected prior to operation of the unit. If you need service, contact Customer Service.

6. Inspect electrical cord for cuts. If a cut is found, DO NOT TOUCH OR USE ELECTRICAL CORD! Replace cord before starting the unit.

Operator’s Manual 17

Operating the Washer

PRIMING THE PUMP

1. It is essential to prime the pump on initial start-up and each time the water supply is disconnected from the unit after initial use.

2. Lay the high pressure hose out to remove any loops. Water ﬂow will constrict the hose, creating tight loops if the hose is not straight.

3. Securely connect the gun assembly to the high pressure hose.

NOTE: The nozzle assembly should NOT be connected to the gun

assembly at this time. See "Nozzle Connection" .

4. With the trigger gun locked in the "OFF" position, turn the water supply completely on. Pointing the gun in a safe direction, unlock the trigger gun and squeeze the trigger.

5. Low pressure water will begin ﬂowing from the hose/gun assembly. This allows the unit to prime and purge any air from the system. The unit is primed when water ﬂow is uninterrupted by air.

6. Once the unit is primed, release the trigger and lock the gun in the "OFF" position. Securely connect the nozzle assy. (See "Nozzle Connection")

START-UP

WARNING: RISK OF INJECTION CAUSING SEVERE INJURY! KEEP CLEAR OF NOZZLE! NEVER PLACE HAND OR FINGERS IN FRONT OF NOZZLE!

DO NOT DIRECT DISCHARGE STREAM AT PEOPLE OR PETS!

BE CERTAIN THE ADJUSTABLE NOZZLE ASSY. IS SECURELY CONNECTED TO THE WAND TO PREVENT AN ACCIDENTAL DISCHARGE!

CAUTION: RISK OF DAMAGE. DO NOT ALLOW SPRAY PATTERN TO REMAIN ON A FIXED AREA FOR AN EXTENDED PERIOD OF TIME. POSSIBLE DAMAGE MAY OCCUR TO THE AREA.

1. Refer to the "Safety Precautions" before starting the unit.

2. Locate the Safety Decals on your unit and heed their warnings.

3. With the gun locked in the "OFF" position, point the trigger gun away from yourself or anyone else. Ensure water supply is turned completely on.

4. Disengage the safety lock-off on the gun and squeeze the trigger. Low pressure water will begin ﬂowing from the nozzle.

5. Before starting the unit, brace yourself as the gun will kick-back from the high pressure created by the pump once the unit has started.

6. Move the On/Off Switch to the "ON" position. This switch includes a circuit breaker for protection of the motor. In case of excess load, the circuit breaker will automatically move the switch to the "OFF" position. To restart, move the On/Off Switch to the "ON" position again.

7. Once the unit is turned on, perform the following procedures with the gun open:

a. Inspect for system water leaks and oil leaks. If an oil leak is found, TURN

UNIT OFF IMMEDIATELY! 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 your John Deere dealer.

b. Inspect high pressure hose for kinking cuts and leaks. If a cut or leak

is found, DO NOT TOUCH HOSE AT CUT OR LEAK!!! TURN UNIT OFF IMMEDIATELY! Replace hose before re-starting the unit. See "Miscellaneous Safety Precautions”. 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 your John Deere dealer.

c. Inspect electrical cord for cuts. If a cut is found, DO NOT TOUCH OR

USE ELECTRICAL CORD! Replace cord before starting the unit.

8. Trigger the gun several times and try adjusting the spray pattern. Be certain to LOCK the trigger gun in the "OFF" position whenever moving the adjustable nozzle. NEVER look directly into the nozzle! High pressure water creates a risk of severe injury!

9. 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 packing seals, resulting in costly pump repair.

10. Because your pressure washer delivers a high pressure spray and a variety of spray patterns, there are many cleaning jobs that can be done without the use of detergents. If a cleaning agent is required, see "Cleaning With Detergents" for the correct procedures.

Operator’s Manual 19

Operating the Washer

CLEANING HORIZONTAL SURFACES

Move nozzle wand from side to side. Direct spray at an angle to force debris ahead and away from the cleared area.

Depending on the material to be removed and nozzle pressure, hold nozzle end 8 to 10 inches (20 to 25 cm) from the surface and use slow, overlapping strokes. If debris is easy to remove, move nozzle back to cover more area for faster cleaning.

CLEANING VERTICAL SURFACES

IMPORTANT: Remember that the washer can deliver

a high pressure spray that can break glass and gouge soft wood and other materials.

When cleaning building interiors or exteriors without detergents, work from top to bottom. This will help eliminate streaks. In interiors, start with the ceiling ﬁrst, then the walls and the ﬂoor last.

Clean around windows carefully. If glass panes are not well-caulked and puttied, the high pressure spray could break the glass.

Never spray directly overhead. Always spray ahead to avoid dripping or falling debris.
