below 2.5 GPM (gallons per minute).
• Flow rate can be determined by running

source.
We strongly recommend that this high

the trigger gun being engaged.
This Kärcher high pressure washer is
equipped with thermal protection to
extend the life of your pressure washer.
The thermal protector will automatically
