Setup
Assembly

Connecting Water Supply
- Connect a standard garden hose (not included) to the water inlet on the pressure washer. Ensure the connection is tight to prevent leaks.
- Connect the high-pressure hose to the outlet on the pressure washer and to the spray gun.
- Turn on the water supply completely.
- Squeeze the trigger on the spray gun to purge air from the system until a steady stream of water emerges.

Operating Instructions
Starting the Unit
- Ensure the water supply is fully open and air has been purged from the system.
- Plug the pressure washer into a grounded electrical outlet.
- Turn the ON/OFF switch to the "ON" position. The motor will start briefly and then shut off due to the Total Stop System (TSS).
- Squeeze the trigger on the spray gun to begin operation. The motor will run only when the trigger is engaged.
Adjusting Pressure and Spray Pattern
The SPX2598 features an adjustable spray wand. Simply twist the nozzle to change the spray pattern from a punishing pinpoint jet to a powerful fan spray, allowing you to tackle various cleaning tasks with ease.

Using the Detergent Tank
For enhanced cleaning, fill the 33.8 fl oz (1 liter) onboard detergent tank with your preferred pressure washer-safe detergent. The detergent will be automatically mixed with the water stream when using a low-pressure spray setting.
