Before you store the pressure washer overnight or 
transport it, disconnect the water supply and 
CLOSE the fuel supply valve.

•

After each use, wipe all pressure washer surfaces 
with a clean, damp cloth.

•

Do not store unit outside where it can be exposed to

•

Do not expose pressure washer to freezing temper-
atures or allow water to freeze in pressure washer 
components which could cause the pump to 
lock-up. If this happens, allow the pump to thaw nat-
urally in a WARM ENVIRONMENT. Do not attempt 
to speed up this process by pouring warm water on 
the pump. This could cause additional damage to 
the pump.
