sunjoe SPX3160 - User Manual

This document describes the Sun Joe SPX3160 11A Electric Pressure Washer, a high-pressure cleaning appliance designed for residential use. It is intended for light-to-medium duty cleaning tasks on various surfaces and items such as boats, motorcycles, RVs, ATVs, trailers, decks, barbecues, siding, and patio furniture.

Function Description:

The pressure washer operates by generating a high-pressure jet of water to effectively remove dirt and grime. It features a pump encased in a shock-absorbing housing and is equipped with a spray wand and a non-slip handle grip for optimal working position and control. The unit is designed to be used with cold or lukewarm water, as higher temperatures can damage the pump. It is crucial to use only clean water, free of impurities, sand, or chemical products, to ensure proper operation and prolong the machine's life.

An important safety and efficiency feature is the Total Stop System (TSS), which incorporates a micro-switch sensitive to water flow. When the trigger gun is released, water flow through the pump stops, and the TSS automatically turns off the motor. This prevents pump overheating, conserves energy, and extends the pump's lifespan. The pressure washer also includes an unloader valve that reduces pressure if it exceeds preset values, and the spray gun has a locking device to prevent unintentional operation. A thermal sensor protects the motor from overloading, allowing the machine to restart after a few minutes once it has cooled.

For enhanced cleaning, the unit comes with a foam cannon, allowing the application of detergents specifically designed for pressure washers. The foam cannon has a foam-volume knob for adjusting the detergent output. The spray wand features an adjustable nozzle that can be rotated to change the spray pattern from a concentrated pencil spray to a wider fan spray, adapting to different cleaning needs.

Usage Features:

Before operation, users must carefully read and understand all instructions and safety symbols. The machine should be checked for any defects, and if found, it should not be started. All visitors and pets must be kept a safe distance from the work area. Proper attire, including safety footwear, snug-fitting clothing, protective gloves, and hearing/head protection, is recommended.

To set up the pressure washer, the spray wand assembly needs to be fitted into the trigger gun and locked. The caster wheels and larger back wheels are installed into the housing. The high-pressure hose connects the trigger gun to the water outlet on the pressure washer. A garden hose adapter (female coupler) connects the garden hose (male end) to the water inlet of the pressure washer. The garden hose must have an internal diameter of at least 13 mm (1/2 in.) and be reinforced, with a water supply capacity at least equal to the washer's delivery capacity. The machine is not suitable for connection to potable water mains.

Electrical safety is paramount. The unit must be plugged into a power outlet with the correct voltage and frequency, and a Ground Fault Circuit Interrupter (GFCI) protection should be provided. The GFCI may need to be reset upon initial plugging in. The pressure washer should be positioned as close as possible to the water supply and used on a secure, stable, upright surface. The motor switch must be in the OFF (0) position before plugging in.

To start, the safety lock on the trigger gun is unlocked, and the trigger is pressed for a few seconds until water flow is steady, allowing air to escape and residual pressure to discharge. With the trigger still pressed, the switch is moved to the ON (I) position to start the motor. The motor only runs when the trigger is depressed.

When working with detergent, only pressure washer-specific cleaning agents should be used. Household detergents, acids, alkaline solutions, bleaches, solvents, flammable materials, or industrial-grade solutions are strictly prohibited as they can damage the machine and cleaning surfaces. Detergent is applied from bottom to top on a dry surface for best results, allowed to sit briefly (but not dry), then rinsed with clean water from top to bottom to avoid streaking. The nozzle should be held 6-8 inches from the surface at a 45° angle.

Maintenance Features:

Regular maintenance ensures optimal performance and longevity. Before any maintenance, the unit must be switched off, and the plug disconnected from the power supply.

The water inlet filter should be checked and cleaned regularly. This involves removing the garden hose adapter and the filter, then rinsing the filter with warm water to prevent foreign matter from clogging the pump. The nozzle should also be cleaned using the provided needle clean-out tool, removing any dirt from the nozzle hole and rinsing it.

For winterizing and long-term storage, especially in locations where temperatures fall below 32°F (0°C), specific procedures must be followed to prevent damage. All water connections should be disconnected, and the machine run for a few seconds to expel remaining water from the pump. The high-pressure hose should not be kinked. The machine and accessories must be stored indoors in a dry, covered, frost-free area, away from heat sources that could dry pump seals. Operating the pressure washer with non-corrosive/non-toxic anti-freeze, a pump saver, or a pump protector before winter storage is recommended. Before reusing, the unit must be completely flushed with clear water to remove any anti-freeze, which can damage paintwork.

In case of troubleshooting, common issues like the machine refusing to start, fluctuating pressure, or stopping can often be resolved by checking power connections, water supply, hose integrity, and cleaning the nozzle or filter. For more complex issues or if parts need replacement, users are advised to contact an authorized Snow Joe® + Sun Joe® dealer or customer service center. Only original replacement parts or manufacturer-approved parts should be used to ensure appliance safety. Servicing of double-insulated appliances requires extreme care and knowledge and should only be performed by qualified service personnel.
