ELECTRICAL SAFETY 1. Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user. 2.
6. Use safety equipment. Always wear eye protection. Nonskid safety shoes, hard hat, or hearing protection must be used for appropriate conditions. Always wear ANSI approved safety impact goggles and thick rubber boots during use and maintenance. TOOL USE AND CARE 1. Use clamps (not included) or other practical ways to secure and support a smaller workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control. 2. Do not force the tool.
SPECIFIC SAFETY RULES 1. Maintain a safe working environment. Keep the work area well lit. Make sure there is adequate surrounding workspace. Always keep the work area free of obstructions, grease, oil, trash, and other debris. Do not use the Pressure Washer in areas near flammable chemicals, dusts, and vapors. 2. Maintain labels and nameplates on the Pressure Washer. These carry important information. If unreadable or missing, contact Harbor Freight Tools for a replacement. 3.
14. Some chemicals or detergents may be harmful if inhaled or ingested. Use an ANSI approved respirator or mask whenever there is a chance that vapors may be inhaled. 15. Keep the High Pressure Hose connected to the Pressure Washer and Spray Gun while the system is pressurized. Disconnecting the Pressure Hose while the unit is pressurized is dangerous, and may cause injury. 16. Prior to starting the Pressure Washer in cold weather, check all of the parts of the unit to make sure ice has not formed.
GROUNDING WARNING! Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the power cord plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use.
EXTENSION CORDS 1. Grounded tools require a three wire extension cord. 2. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. (See Table A.) 3. The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
ASSEMBLY NOTE: For additional information regarding the parts discussed in the following pages, refer to the Assembly Diagrams on pages 19-21. 1. Check the Inlet Strainer for any blockage, including packaging debris. The Pressure Washer may be shipped with a plastic plug in the Inlet. 2. If you have not already done so, remove the foam packing block underneath the Top Shell (4A). 3. Position the rear of the Handle (1A) above the rear of the Pressure Washer body.
4. Insert the Spray Wand (9C) or Turbo Wand (33C) into the Spray Wand Extension (8C), and twist the Wand into the Extension until the Wand locks in place. Pull the Wand to make certain it is secure. (See Figure E.) SPRAY WAND EXTENSION (8C) SPRAY WAND (9C) TURBO WAND (33C) 5. FIGURE E If using the Brush Wand (34C), insert the Brush Wand into the Brush Adapter (35C) and twist the Wand into the Adapter until the Wand locks in place.
CONTROLS AND SETUP Note: Familiarize yourself with the location and function of all of the machines controls before proceeding to setup of the machine. CONTROLS AND FEATURES 1. The Pressure Washer features an automatic On/Off Micro Switch (42B). The Motor (3A) of the Pressure Washer does not run continuously, but only when the Trigger (21C) is squeezed. When spraying water through the unit stops, the Motor will automatically shut off. 2.
Pattern Adjustment Pressure Adjustment NOZZLE SPRAY WAND (9C) FIGURE J - ADJUSTMENTS 5. The Turbo Wand (33C) features a fixed Nozzle which increases the Pressure Washer’s effectiveness and decreases its cleaning area, and is recommended for heavy duty cleaning of small areas. The spray pattern on the Turbo Wand is not adjustable, but provides a circular water pattern as it sprays the high pressure water.
SETUP 1. CHECK THE WATER SUPPLY. Prior to using the Pressure Washer for the first time, it is ESSENTIAL to verify that the water supply is adequate. The Pressure Washer needs TWICE the water supply (or volume) than the stated water output (2.1 GPM). This Pressure Washer will need about 3-4 GPM to operate correctly and efficiently. If the water is being supplied by a well/pump, make certain that the well/pump produces enough water to keep up with the Pressure Washer’s water demands.
OPERATION 1. Make sure the Power Switch is in the “OFF” position. (See Figure M.) 2. Attach the heavy duty hose to the Pressure Washer, using the Quick Connector Set (36C). (See Figure G.) 3. Attach the Spray Wand (9C), Turbo Wand (33C), or Brush Wand and Adapter (34C, 35C) into the Spray Wand Extension (8C), and press and twist the Wand into the Extension until the Wand locks in place. (See Figures E and F.) NOTE: The Pressure Washer will not pressurize if the Nozzle is not completely assembled.
WARNING: Do not disconnect the high-pressure hose or water inlet hose until all pressure is discharged safely. 9. IMPORTANT! When turning off the unit after use, high pressure will remain inside the unit its High Pressure Hose (24C), and the water inlet hose. Point the Wash Gun (5A) in a safe direction and discharge all remaining pressure. The high-pressure hose and water inlet hose can be disconnected after the pressure is released. 10.
a. Do not release the trigger between sweeps. Release the trigger as few times as possible during use. Interrupted or sporadic spraying will cause the unit to heat up quickly and will increase the need for rest periods. b. Make sure that all obstacles have been moved and the entire area is ready before starting. c. For small jobs, try to finish an entire portion of the job before taking a break. CLEANING RECOMMENDATIONS 1.
less solid surfaces while trying to clean the harder ones. This is especially a concern when cleaning tile and grout, bricks and mortar, or stones and mortar. 7. If wood is being cleaned, be careful not to damage it. Wood will usually require resurfacing (sanding) and re-coat with a surface protectant (wood, stain, varnish) after it has dried again. Try to avoid leaving water on a wooden surface; doing so can harm the surface. INSPECTION, MAINTENANCE, AND CLEANING 1.
