FAQs

Can I use this pressure washer indoors?

No. Because this unit is powered by a petrol engine, it produces exhaust fumes and must only be used in well-ventilated outdoor environments.

Does this machine require a mains water connection?

No, it is capable of self-priming and can draw water from natural reserves such as lakes, ponds, or water tanks.

How often should I clean the water filter?

Inspect the water filter before every use, especially if pulling water from non-mains sources, to prevent debris from damaging the pump.

Is the engine maintenance difficult?

The Honda GX 160 is a reliable, widely serviced engine. Routine maintenance includes regular oil changes and air filter checks as per the engine manual.

Can I use this to clean sensitive surfaces?

The pressure can be adjusted or the distance from the surface increased; however, always test on an inconspicuous area first to avoid surface damage.

Troubleshooting

Engine fails to start

Check fuel levels, ensure the ignition switch is in the 'On' position, and inspect the spark plug lead.

Low water pressure

Check the water inlet filter for blockages, ensure the hose is not kinked, and verify that the pump is priming correctly.

Machine vibrating excessively

Ensure the machine is on flat ground and check that all frame bolts and accessories are tightened securely.

Setup, Compatibility & Care

Setting up the HD 7/15 G is simplified through the use of `EASY!Lock` connectors, which eliminate the need for wrenches when attaching the 10-metre hose or the 840mm spray lance. Before operation, always check the engine oil level and ensure the petrol tank is filled with the correct grade of fuel. For care, ensure the large water filter is inspected periodically and cleared of debris to maintain proper flow. When using natural water sources, ensure the intake hose is submerged properly to avoid drawing air. After use, purge any remaining pressure from the system by engaging the trigger before disconnecting hoses. Store the unit in a dry, ventilated area to prevent corrosion and protect the engine.
