Equipped with a built-in thermal relief valve, the pump is protected from overheating caused by improper operation, which significantly extends its service life. Starting is effortless thanks to an engine-pump linkage decompression system, while the powerful cleaning performance—15 L/min at up to 3,625 psi for the G3600B and 4,000 psi for the G250B—quickly removes compacted mud, heavy grease, oil residue, and loose paint from concrete, machinery, and vehicle surfaces. Additionally, the self-priming function allows the washer to draw water directly from buckets, ponds, or tanks without a pressurized tap connection, making it ideal for remote job sites.

Designed for professional and commercial cleaning, the G3600B / G250B gasoline pressure washer performs exceptionally well in these key areas:

• Performing daily cleaning and upkeep of agricultural machinery and farm equipment

• Eliminating oil, grease, and heavy sludge from industrial floors and large machinery

• Washing away mud, grime, and concrete residue from construction vehicles and on‑site equipment

How long is the warranty?

All units are covered by a 1-year warranty. During this period, any defective parts will be replaced free of charge, with replacements shipped to Shanghai/Ningbo ports (usually combined with your next order).

How does the pressure washer prevent overheating damage?

The pump is equipped with a built-in thermal relief valve. This valve automatically protects the unit from overheating caused by improper operation (such as running the pump with no water flow), which significantly extends the machine's service life.

What is the standard lead time?

For trial orders, lead time is around 15–20 days after order confirmation. For bulk orders, it depends on quantity – typically 25–35 days.

Is it easy to start, especially after long periods of non-use?

Yes. The pressure washer features an engine-pump linkage decompression system, which reduces starting resistance. This makes the engine effortless to start every time.
