This document describes the DEWALT DXPW3200V Vertical Pressure Washer, a tool designed for professional applications.
Function Description
The DEWALT DXPW3200V is a vertical pressure washer used for cleaning various surfaces with high-pressure water. It operates by increasing the pressure of a water supply using a high-pressure pump, which is driven by an engine. The pressurized water is then carried through a high-pressure hose to a spray gun and spray wand, allowing the user to control the water flow rate, direction, and pressure. The device features a quick-connect spray wand system that allows for rapid changing of high-pressure nozzles, which come in different colors to indicate various spray patterns and intended uses. It also includes a detergent injection system to mix cleaners or cleaning solvents with water, enhancing cleaning effectiveness.
Important Technical Specifications
- Model: DXPW3200V
- Pressure: 3200 PSI (Pounds per Square Inch) - This is the unit of measure for water pressure.
- Water Flow Rate: The minimum requirement for a water supply is 38 liters per minute (LPM) at 20 psi.
- Engine: The engine drives the high-pressure pump. Specific engine details are found in the separate Engine Owner's Manual.
- Fuel: Requires fresh, high-quality, unleaded petrol with a pump octane rating of 86 or higher. Ethanol Shield™ fuel stabilizer is recommended. Fuels with greater than 10% ethanol are not approved.
- Water Supply: Must be cold water only. The garden hose length should not exceed 9 meters if the water source is a well.
- Nozzles: Five quick-connect nozzles are provided, color-coded for different spray patterns:
- 0° (Red): Powerful pinpoint spray for very intense cleaning (metal or concrete, NOT on wood).
- 15° (Yellow): Intense cleaning of small areas (metal, concrete, or wood).
- 25° (Green): Intense cleaning of larger areas (metal, concrete, or wood).
- 40° (White): Covers wide areas of cleaning (metal, concrete, wood, or vinyl).
- Low Pressure (Black): Applies chemical/cleaning soaps (metal, concrete, wood, or vinyl).
- Pump: The pump is maintenance-free and does not require oil to be added or changed.
- Thermal Relief Valve: This valve opens to release a gush of water if the pump temperature rises too high, preventing damage.
- Bypass Mode: Allows water to re-circulate within the pump when the gun trigger is not pulled, enabling repositioning without turning off the engine.
Usage Features
- Assembly: The handle is assembled onto the frame using snap buttons. The high-pressure hose connects to the spray gun, and the spray wand connects to the spray gun. Nozzles are inserted into a color-coded holder on the panel assembly. Tyre pressure should be checked and adjusted if needed.
- Pressure Adjustments: The pressure is preset for optimum cleaning. To lower pressure, move the nozzle further from the surface or switch to the 40° (white) nozzle. Users are warned NOT to attempt to increase pump pressure beyond factory settings.
- Spray Wand Use: Nozzles are changed by pulling back the quick-connect coupler, inserting the desired nozzle, and releasing the coupler to secure it. The engine must be off when changing nozzles.
- Chemical/Cleaning Solvents Application: Chemicals are applied at low pressure. The detergent tank (12) is filled with cleaning solvent, and the black low-pressure nozzle is installed on the spray wand. After use, the detergent tank should be rinsed with clean water to prevent pump damage. Only chemical/cleaning soaps specifically recommended for high-pressure washers should be used; bleach is prohibited.
- Starting Procedure:
- Add fresh, unleaded petrol (86+ octane) to the fuel tank, ensuring it's 12.7 mm below the filler neck.
- Check engine oil level.
- Connect the water hose to the water source and turn it on to remove air until a steady stream of water is present, then turn it off.
- Verify the filter screen (13) is in the pump inlet (10) with the convex side facing out.
- Connect the water source (14) to the pump inlet (10).
- Connect the high-pressure hose (3) to the pump outlet (9).
- Select the appropriate nozzle.
- Turn the water source on.
- Depress the spray gun trigger until a steady stream of water is present to remove air from the pump and hose.
- Start the engine (refer to Engine Owner's Manual).
- Depress the trigger on the gun to start water flow.
- Shutting Down Procedure:
- If chemicals were used, rinse the detergent injection system with clean water.
- Turn off the engine.
- Turn off the water source.
- Pull the spray gun trigger to relieve any water pressure in the hose or gun.
- Safety Features: Includes warnings for hot surfaces, fluid injection, lifting hazards, electrical shock, chemical burns, bursting risks (tyres), and carbon monoxide poisoning. A trigger lock (15) is present on the gun to prevent accidental spraying.
Maintenance Features
- Routine Maintenance: A routine maintenance schedule is recommended for efficient operation and longer life. More frequent checks are needed in unusual conditions (high temperatures, dusty environments).
- Engine Maintenance: Refer to the Engine Owner's Manual for specific recommendations.
- Pump Maintenance: The pump is maintenance-free and does not require oil changes. For issues, contact DEWALT support.
- Connections: Hoses, gun, and spray wand connections should be regularly cleaned and lubricated with light oil or lithium grease to prevent leakage and damage to o-rings.
- Nozzle Cleaning (Fig. L): If the nozzle becomes clogged, it should be cleaned using the provided nozzle cleaning tool and backflushed with clean water. The high-pressure nozzle (11) is removed from the spray wand for cleaning.
- Water Inlet Filter Cleaning (Fig. H): The filter (13) should be checked periodically and cleaned by removing it from the pump inlet and flushing it with water. The cone side must face out when re-inserting.
- Storage:
- Engine Storage: Follow the Engine Owner's Manual. To prevent fuel-related problems, add fuel stabilizer, run the engine for 10 minutes, turn the fuel valve to OFF, and continue running until the engine stops from lack of fuel (less than 3 minutes).
- Pump Storage: Use SIMPSON® / POWERWASHER® Pump Guard or equivalent, especially if storing for more than 30 days or in freezing temperatures. This involves attaching the Pump Guard bottle to the water inlet, squeezing its contents into the pump, and simultaneously pulling the starter rope with the ignition switch off until protector fluid exits the pump outlet.
- Pressure Washer Storage: Drain all water from the high-pressure hose, spray gun, and wand. Secure the detergent siphon hose. Store the unit in an upright position.
- Warranty:
- Engine: Covered by engine manufacturer warranty.
- High Pressure Pump: Two (2) years from date of purchase for defects in material and workmanship.
- Frame: Five (5) years from date of purchase for defects in material and workmanship.
- Other Components (nozzles, hoses, spray guns, wands, tires, feet): Ninety (90) days from date of purchase for defects in material and workmanship.
- The warranty is subject to the Consumer Guarantees Act (NZ) or Australian Consumer Law, providing rights for repair, replacement, or refund for major failures. It does not cover normal wear and tear, damage from improper maintenance, storage, abuse, or unauthorized repairs.
