Pre-Operation Check; Prepare The Air Filter - Benchmark BW4400 Mode D'emploi

3. PRE-OPERATION CHECK

These quick checks should be done each time the pressure washer is started to
ensure you get the most out of your pressure washer.
Set the pressure washer on a level surface and the power switch to OFF.
WARNING!
Exhaust gas contains poisonous carbon monoxide. Never run the pressure
washer in an enclosed area. Be sure to provide adequate ventilation.
Operate the pressure washer on a level surface. If the pressure washer is
tilted, fuel spillage may result. Keep away from rotating parts while the
pressure washer is running. The pressure washer is air-cooled and may
be damaged if ventilation is inadequate.
