pressure washer 
approved
Use only detergents, degreasers, waxes and 
other cleaning solutions that are designed 
specifically for pressure washers. Cleaners in 
this category will clearly state on the label that 
they are meant for use in pressure washers. Do 
NOT use any other type of cleaning solution in 
your high-pressure washer. Never use bleach, 
ammonia, any type of acid or hot water in your 
appliance!
The suction tube 
has become 
disconnected, 
clogged or kinked
Ensure the suction tube is not damaged and 
is properly connected to the detergent nozzle. 
Reconnect, clean or replace the tube as 
needed.
Detergent nozzle is 
clogged with debris
Clean the nozzle according to the instructions 
provided in the Nozzle paragraph under the 
Maintenance section of this manual.
Detergent to water 
ratio
The pressure washer draws detergent at a 
maximum 10:1 water to detergent ratio. Most 
pressure washer detergents are concentrated 
within this range so minimal adjustment of the 
detergent nozzle metering valve is required. If 
you feel you are using more detergent than is
required for the application, you can dilute the 
detergent with regular tap water.
