13. Never carry your pressure washer by the cord. Do not pull on the cord to disconnect from the outlet.
14. To prevent damage, the cord should not be crushed, placed next to sharp objects, or near a heat source.
15. Check power cords before using. Damaged cords can reduce performance of pressure washer or cause a fatal electrical shock.
16. The narrow pin point stream is very powerful. It is not recommended for use on painted surfaces, wood surfaces, or items attached with an adhesive backing.
17. Keep operating area clear of all persons and animals.
18. Always use both hands when operating pressure washer to maintain complete control of the wand.
19. Do not touch nozzle or water spray while operating. Never place hands in front of nozzle.
20. Wear safety goggles while operating. Wear protective clothing and footwear to protect against accidental spraying.
21. Disconnect power plug from the outlet when not in use, and prior to the detaching of the high-pressure hose.
22. Never tie knots or kink the high-pressure hose as damage could result. Inspect the high-pressure hose regularly. Replace the hose immediately if it is damaged, worn or shows any signs of cracks, bubbles, pinholes, or other leakages. Never grasp a high-pressure hose that is leaking or damaged.

GROUND INSTRUCTIONS

This product must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This product is equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

WARNING: Improper connection of the equipment-grounding conductor can result in a risk of electrocution. Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the product if it will not fit the outlet installed by a qualified electrician. Do not use any type of adapter with this product.

Power Supply And Electrical Info

GROUND-FAULT CIRCUIT-INTERRUPTER PROTECTION
The pressure washer is factory-equipped with an electrical cord and a Ground Fault Circuit Interrupter (GFCI) power plug. This device provides additional protection from the risk of electric shock. This cord should only be connected to an electrical outlet installed in accordance with local safety regulations. Should replacement of the plug or cord become necessary, use only identical replacement parts that include GFCI protection.
NOTE: The power supply must be 120 V, 60 Hz, and a minimum 13.5 amp dedicated electrical circuit.
A. Inspect cord before using. Do not use if cord is damaged.
B. Keep all connections dry and off the ground.
C. Do not touch plug with wet hands.
D. The pressure washer is provided with a ground fault circuit interrupter built into the power plug.
If replacement of the plug or cord is needed, use only identical replacement parts. Contact customer service for proper replacement parts.
WARNING: Test GFCI before each use. DO NOT use pressure washer if test below fails. GFCI Test Procedures:

1. Plug GFCI into power receptacle. Indicator light should illuminate.
2. Press test button (X). Light should turn off.
3. Press reset button (Q) for use. Indicator light should illuminate. Do not use if above test fails.
   

NOTE: The GFCI must be reset each time the pressure washer is connected to an electrical outlet. Reset by simply pushing the reset button on the GFCI power plug.

DO NOT USE AN EXTENSION CORD WHILE OPERATING THE PRESSURE WASHER.

• NOTICE: The high-pressure spray from your pressure washer is capable of causing damage to surfaces such as wood, glass, automobile paint, auto striping and trim, delicate objects such as flowers and shrubs. Before spraying. check the item to be cleaned to assure yourself that it is strong enough to resist damage from the force of the spray.

CHANGING NOZZLES AND SPRAY WAND

DANGER: Risk of fluid injection. Do not direct discharge stream toward persons, unprotected skin, eyes or any pets or animals. Serious injury will occur.
WARNING: Flying object could cause risk of serious injury. Ensure nozzle is completely inserted in quick-connect socket and quick-connect collar is fully engaged (forward) before squeezing gun trigger.

1. Pull quick-connect coupler back and insert nozzle.
2. Release quick-connect coupler and twist nozzle to make sure it is secure in coupler.
   WARNING: Flying object could cause risk of serious injury. Ensure nozzle is completely inserted in quickconnect socket and quick-connect collar is fully engaged (forward) before squeezing gun trigger.

Starting
WARNING: To reduce the risk of injury, read the sanitizing mister and pressure washer system instruction manual before starting pressure washer.
DANGER: Risk of fluid injection and laceration. When using the high- pressure setting, DO NOT allow the high-pressure spray to come in contact with unprotected skin, eyes, or with any pets or animals. Serious injury will occur.

• Your washer operates at fluid pressures and velocities high enough to penetrate human and animal flesh, which could result in amputation or other serious injury. Leaks cause by loose fittings or worn or damaged hoses can result in injection injuries. DO NOT TREAT FLUID INJECTION AS A SIMPLE CUT! See a physician immediately!
  NOTICE: NEVER pull water supply hose to move pressure washer. This could damage hose and/or pump inlet.

• DO NOT use hot water, use cold water only. · Never turn water supply off while pressure washer motor is running or damage to pump will result.

• DO NOT stop spraying water for more than two minutes at a time. Pump operates in bypass mode when spray gun trigger is not pressed. When the temperature inside the pump rises too high, the thermal relief valve (T), will open and release a gush of water in an effort to lower the temperature inside the pump. The thermal relief valve will then close. If pumps is left in bypass mode for more than two minutes, internal components of the pump can be damaged.
  

WARNING: Do not allow the unit to run for more than two minutes without the spray gun trigger being pulled. This could cause overheating and damage to the pump. When temperature inside the pump rises too high, the thermal relief valve will open and release a spray of water from the pump to lower the internal temperature. The valve will then close.

QUICK SETUP GUIDE

WARNING: To reduce the risk of injury, read the pressure washer instruction manual before operating pressure washer.

1. Install the Handle
   Slide the handle assembly (H) onto the frame (F). Align handle assembly holes with frame holes. Insert saddle bolts (R) and secure in place with knobs (R). Tighten until snug.

2. Install the Nozzles
   Remove the four colored quick-connect high-pressure nozzles from the plastic bag, and insert them into correct grommet nozzle holder. Nozzles are color coded to match colored nozzles on panel assembly.

3. Assemble Spray Gun and Wand
   Connect wand (E) to spray gun (I). Make sure connection is secure.
   NOTE: Always check high-pressure pump oil level before using. Add as required.

DANGER: Risk of fluid injection and laceration. When using the high- pressure setting, DO NOT allow the high-pressure spray to come in contact with unprotected skin, eyes or with any pets or animals. Serious injury will occur.
