Frequently Asked Questions - ERAF 0621A GREE

How do I start the pressure washer?

Ensure the water supply is connected and turned on. Switch the power button to ON, unlock the trigger safety, and squeeze the trigger. The motor will start automatically. Release the trigger to stop the motor.

Can I use a bucket instead of a garden hose?

Yes, the ERAF 0621A can draw water from a barrel or bucket. Use the supplied suction hose with a filter and ensure the water level is at least 1 meter above the pump to prevent air intake.

How do I use the detergent function?

Fill the detergent tank with approved cleaning solution. Attach the low-pressure nozzle (black tip) to the gun. Squeeze the trigger to apply detergent. For rinsing, switch to a high-pressure nozzle (e.g., 25° or 40°).

What type of detergent can I use?

Use only detergents specifically designed for pressure washers. Avoid bleach, acidic, or flammable liquids. Gree recommends pH-neutral or mild alkaline cleaners.

How do I maintain the pump?

After each use, flush the pump with clean water for 1 minute. Check oil level every 50 hours of use. Use only SAE 30 non-detergent oil. Change oil annually or after 200 hours.

What should I do if the pressure drops?

Check for blocked nozzles, kinked hose, or dirty water filter. Turn off the machine, clean the nozzle with a pin, straighten the hose, and rinse the filter under running water.

Can I use an extension cord?

Yes, use a heavy-duty extension cord rated for outdoor use, with a minimum cross-section of 1.5 mm² and length up to 20 m. Unroll the cord fully to prevent overheating.

How do I store the pressure washer in winter?

Drain all water from the pump, hose, and nozzles. Disconnect all hoses. Store the unit in a frost-free location (above 0°C). Apply a small amount of pump antifreeze if necessary.

What spare parts are available for this model?

Common spare parts include replacement nozzles (0°, 15°, 25°, 40°), high-pressure hose, trigger gun, water filter, seals, and pump oil. Contact Gree support or authorized dealers.

Is the pressure washer safe to use on my car?

Yes, but use a wide-angle nozzle (40°) and keep a distance of at least 30 cm. Avoid direct jet on locks, mirrors, and tires. Use the low-pressure setting with the detergent nozzle for cleaning.
