INSTALLATION & PREPARATION

ADJUSTABLE PRESSURE DUAL LANCE:

This unit features an Adjustable Pressure Dual Lance which allows the user to

select a high or low pressure “fan” spray. Simply rotate the adjustable grip on

the dual lance to achieve the desired pressure selection.

1. Selection of high pressure can be achieved by turning the adjustable grip on

the Dual Lance assembly counterclockwise as shown in the gure below.

2. Selection of low pressure can be achieved by turning the adjustable grip on

the Dual Lance clockwise as shown in the gure below.

DUAL LANCE CONNECTION:

1. Be certain the trigger gun is locked in the “OFF” position.

2. Connect the dual lance assembly to the trigger gun assembly at this time

(if applicable). Be certain the connection is securely tightened.

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 ow 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 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 completely turned on.

WARNING

RISK OF INJECTION CAUSING

SEVERE INJURY!

-THE TRIGGER GUN SHOULD

ALWAYS BE LOCKED IN THE OFF

POSITION WHEN NOT IN USE!

INSTALLATION & PREPARATION

UNLOADER:

Standard Models:

The unloader has been preset at the factory.

Steam Option Models:

The unloader has an adjustment knob which has a minimum/maximum setting.

Move the unloader clockwise to the maximum setting for Cold/Hot water

operation. Move counterclockwise to minimum setting for Steam operation.

THERMAL RELIEF 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 relief valve has been added to this unit to protect the pump. This

valve will 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. Inspect the electrical cords for cuts. If a cut is found, DO NOT TOUCH OR

USE CORD! Replace cord before starting unit.

2. Check the oil level in the pump.

3. Inspect the water inlet strainer. Clean or replace if necessary. See “Water

Supply”, #2, pg 14.

4. Check all hose connections to ensure they are securely tightened.

5. 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. 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. 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 or Severe Cutting Injury”, pg. 6. Be sure that all damaged

the coil from the previous usage to turn brown or black. This 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 MODELS:

1. Turn on the water supply.

2. Low pressure water will begin owing from the water outlet. This allows

the unit to ush any particles from the system. The unit is ushed when

the water is clear.

3. Once the system is ushed, turn off the water supply 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.

5. Turn on the water supply.

FLOAT TANK MODELS:

1. Turn on the water supply.

2. Move the switch to the “Pump” position. Low pressure water will begin

owing from the water outlet. This allows the unit to ush any particles from

the system. The unit is ushed when the water is clear.

3. Once the system is ushed, 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:

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, 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 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 ngers 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.

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 19 for the correct procedures.

CAUTION

RISK OF UNIT DAMAGE.

BE CERTAIN THE HOSE, GUN
