TIPS FOR EXTENDING THE LIFE OF
YOUR PRESSURE WASHER
1. Never operate the unit without water.
2. Your pressure washer is not meant to
pump hot water. Never connect your
pressure washer to a hot water supply
as it will significantly reduce the life of
the pump.
3. Running the unit for more than 2
minutes without spraying water caus-
es heat to build up in the pump. This
is hard on many of the pump compo-
nents and this practice should be
avoided.
4. Release the trigger prior to switching
lance between high and low pressure.
Failure to do so may reduce the life of
the o-rings in the lance.
