DANGER: RISk Of fLUID INjECTION AND LACERATION
WHat can HaPPen
• Your pressure washer
operates at fluid pressures
and velocities high enough
to penetrate human and
animal flesh, which could
result in amputation or
other serious injury. Leaks
caused by loose fittings or
worn or damaged hoses
can result in injection
injuries. DO NOT TREAT
FLUID INJECTION AS
A SIMPLE CUT! See a
physician immediately!
HoW to PreVent It
• Inspect the high­pressure
hose regularly. Replace
the hose immediately if it is
damaged, worn, has melted
from contacting the engine,
or shows any signs of
cracks, bubbles, pinholes, or
other leakage. Never grasp a
high-pressure hose that
is leaking or damaged.
• Never touch, grasp or
attempt to cover a pinhole
or similar water leak on the
high-pressure hose. The
stream of water IS under
high pressure and WILL
penetrate skin.
• Never place hands in front
of noz zle.
• Direct spray away from self
and others.
• Make sure hose and fittings
are tight ened and in good
condition. Never hold onto
the hose or fittings during
op er a tion.
• Injuries can result if system
pressure is not reduced
before attempting
maintenance or
disassembly.
