fire explosion.
• Operating the pressure washer in an
explosive environment could result in
a fire.
• Materials placed against or near the
pressure washer can interfere with
its proper ventilation features causing
overheating and possible ignition of
the materials.
• Muffler exhaust heat can damage
painted surfaces, melt any material
sensitive to heat (such as siding,
plastic, rubber, vinyl or the pressure
hose, itself), and damage live plants.
• Improperly stored fuel could lead to
accidental ignition. Fuel improperly
secured could get into the hands of
children or other unqualified persons.
