04 jetting and collection
Arrange the work method according to the material, isolate splashing and collect the wastewater.
Professional selection
Pressure, flow rate, and site conditions should be considered together.
Do not take the maximum value as the continuous operating value, and do not take the theoretical hydraulic power as the rated power.
Pressure and flow rate
Working pressure, maximum pressure, and adjustable range are different for different diameters; they should be verified separately based on the original settings of this model and actual operating conditions.
Power and Environment
Gasoline internal combustion engines are not used in indoor or semi-enclosed spaces; outside, the machine's instructions still apply to tailpipe emissions, fire sources, and fuel management.
Water supply and working attachment
Continuous water supply, pipeline pressure resistance, and nozzle need to be matched; do not derive multi-gun capability or fixed area efficiency based on the entire machine's flow rate.
