Usage Features
The pressure washer offers several features to enhance usability and versatility:
- Quick Connect Spray Tips: The nozzle extension allows for easy switching between five different quick-connect spray tips, each designed for specific applications:
- Magenta (Low Pressure): For applying detergent.
- White 40° (2800 PSI, 2.4 GPM): For delicate rinse and gentle cleaning of cars/trucks, boats, RVs, patio furniture, and lawn equipment.
- Yellow 15° (3000 PSI, 2.4 GPM): For general rinsing and all-purpose cleaning of home siding, brick patios, wood decks, driveways, sidewalks, and garage floors.
- Cyan (Jet Flush): For quick high-flow clean-up and long-reach cleaning of second-story siding and windows.
- Red 0° (3200 PSI, 2.3 GPM): For maximum rinsing, stubborn or hard-to-reach surfaces, paint removal, oil stains, rust removal, and other stubborn substances (tar, gum, grease, wax).
- Detergent Application: The unit includes a detergent tank and a magenta spray tip specifically for applying detergents or soaps. Only pressure washer safe detergents/soaps should be used.
- Automatic Cool Down System: This system cycles water through the pump when water reaches above 125°F (51°C), preventing internal pump damage.
- Accessory Tray: The unit is equipped with an accessory tray to store the spray gun, nozzle extension, high-pressure hose, and quick-connect spray tips, ensuring all components are organized and easily accessible.
- Rope Guide: A rope guide is attached to the handle to route the engine recoil rope, aiding in starting the engine.
- Water Supply Requirements: Requires a minimum of 10 ft. (3 m) of unrestricted garden hose between the pressure washer inlet and any device like a vacuum breaker or check valve. Only cold water (less than 100°F/38°C) should be used.
- Engine Starting: The engine is started manually using a recoil starter. Users are instructed to relieve spray gun pressure before pulling the starter cord and to pull the cord slowly until resistance is felt, then rapidly to avoid kickback.
Maintenance Features
Regular maintenance is crucial for the longevity and performance of the pressure washer. The manual outlines several maintenance procedures:
- Daily/Before Use:
- Check for debris around the pump and clean if necessary.
- Inspect cooling air slots and openings.
- Check for properly tightened hose connections.
- Check engine oil level.
- Check fuel level.
- Check high-pressure hose for kinks, cuts, or damage.
- Check spray gun and nozzle extension assembly.
- Flush garden hose to remove debris.
- After Each Use:
- Shut off the engine and water supply.
- Release retained high water pressure by pressing the red button and squeezing the spray gun trigger.
- Disconnect the high-pressure hose from the spray gun and pump outlet.
- Drain water from the hose, gun, and nozzle extension.
- Place the spray gun, nozzle extension, and spray tips in the accessory tray.
- Hang the high-pressure hose on the hook of the accessory tray.
- Empty pump of all pumped liquids by pulling the recoil handle multiple times.
- Store the unit in a clean, dry area.
- Engine Maintenance: Refer to the engine operator's manual for specific instructions on oil changes, spark plug replacement, air filter cleaning, and fuel system maintenance.
- Pump Maintenance:
- Pump Saver: Use Pump Saver (Model 6039) to protect the pump from mineral deposits, freezing, and to lubricate pistons and seals, especially during storage.
- Detergent Tank Maintenance: Empty and flush the detergent tank after each use.
- Detergent Siphoning Check Ball: Periodically check the check ball in the detergent siphoning system for proper movement. If it becomes stuck from storage, dried soap, or minerals, it needs to be freed.
- Spray Gun Maintenance: Regularly examine the hose connection to the spray gun for security and test the trigger mechanism to ensure it springs back correctly.
- Spray Tip Maintenance: Clean clogged or restricted spray tips using a small paper clip to remove foreign material, followed by back flushing with a garden hose.
- O-Ring Maintenance: An O-Ring/Maintenance Kit (Model 705001) is available for purchase to replace worn o-rings, rubber washers, and water inlet filters.
- Winter Storage: Protect the unit from freezing temperatures by emptying the detergent tank, flushing the system, and treating the pump with Pump Saver. If Pump Saver is unavailable, RV-antifreeze can be used.
- Long Term Storage: For storage longer than 30 days, prepare the engine and pump. Use a fuel stabilizer for the engine's fuel system or drain the gasoline.
The manual emphasizes several critical safety warnings:
- Carbon Monoxide Hazard: Engine exhaust contains carbon monoxide, a poisonous gas. Operate ONLY outdoors, far from windows, doors, and vents.
- Fuel Hazard: Fuel and its vapors are extremely flammable and explosive. Handle fuel outdoors, away from ignition sources, and ensure proper storage.
- High Pressure Stream Hazard: The high-pressure stream can cut through skin and underlying tissues, causing serious injury or amputation. NEVER point the spray gun at people or animals, or exchange spray tips without the trigger lock engaged.
- Kickback Hazard: The spray gun can kick back when spraying, potentially causing falls or injuries. Grasp the spray gun firmly with both hands.
- Electrocution Hazard: NEVER spray near a power source.
- Slippery Surface Hazard: Pressure washer use can create puddles and slippery surfaces, leading to falls. Operate from a stable surface and ensure adequate drainage.
- Chemical Burn Hazard: Use ONLY pressure washer safe detergents/soaps and follow manufacturer instructions.
- Eye Injury Hazard: Always wear indirect vented (chemical splash) safety goggles that comply with ANSI Z87.1.
- Hot Surface Hazard: Engine parts, especially the muffler, can become very hot and cause burns. Allow equipment to cool before touching.
- Spark Arrester: In certain jurisdictions, a spark arrester is required for operation in forest-covered, brush-covered, or grass-covered lands.
The manual also includes a warranty section, detailing coverage for various components and conditions, and advises users to register their product online for warranty coverage.
