Always read the entire owner's manual before operating the unit.
Always wear safety glasses, hearing protection, gloves, and appropriate footwear when operating the pressure washer.
Familiarize yourself with all controls and safety features. Never point the spray gun at people, animals, or electrical outlets. Keep children and pets away from the operating area.
Setup
Follow these steps to prepare your pressure washer for first use:
- Unboxing: Carefully open the box and remove all components. Ensure all parts listed in your owner's manual are present.
- Assembly: Assemble the pressure washer unit according to the instructions in your manual. This typically involves attaching the handle and wheels.
- Add Engine Oil: Before starting, add the recommended engine oil (10W-30) to the engine crankcase. Use the provided oil funnel to prevent spills. The unit has a 0.6 qt. oil capacity.
- Move Outside: Always operate the pressure washer outdoors in a well-ventilated area to prevent carbon monoxide buildup.
- Add Gasoline: Fill the fuel tank (0.9-gallon capacity) with fresh, unleaded gasoline. Do not overfill.
- Assemble Trigger Gun: Connect the spray wand to the trigger gun.
- Attach Nozzle: Select the appropriate quick-connect nozzle for your task (0°, 15°, 25°, 40°, or soap nozzle) and attach it securely to the spray wand.
- Connect High-Pressure Hose: Connect one end of the 50-foot high-pressure hose to the pump outlet and the other end to the trigger gun.
- Connect Water Supply: Connect a garden hose to the pressure washer's water inlet. Ensure the garden hose is free of kinks and has a steady water supply.
- Purge Air: Turn on the water supply. Squeeze the trigger on the spray gun to purge air from the system until a steady stream of water flows out. This prevents damage to the pump.

Operation
Once setup is complete, you are ready to operate your pressure washer:
- Starting the Engine: Follow the starting procedure outlined in your owner's manual. This typically involves setting the choke, turning on the fuel valve, and pulling the recoil start handle.
- Nozzle Selection: The pressure washer includes five quick-connect nozzles (0°, 15°, 25°, 40°, and soap). Choose the appropriate nozzle for your cleaning task. The 0° nozzle provides a concentrated stream for tough stains, while the 40° nozzle offers a wider, gentler spray for delicate surfaces.
- Detergent Application: For applying cleaning detergents, use the black soap nozzle and the 4-foot detergent hose. Place the end of the detergent hose into a bucket of pressure washer-safe detergent. The unit will draw detergent at low pressure.
- Cleaning: Hold the spray gun firmly with both hands. Start spraying a few feet away from the surface and gradually move closer until the desired cleaning effect is achieved. Always test on an inconspicuous area first.
