instruction manual and the engine instruction manual before starting
pressure washer.
DANGER: Risk of fluid injection and laceration. When using the
high pressure setting, DO NOT allow the high pressure spray to come
in contact with unprotected skin, eyes, or with any pets or animals.
Serious injury will occur.
• Your 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!
DANGER: Carbon Monoxide. Using an engine indoors can kill
you in minutes. Engine exhaust contains high levels of carbon
monoxide (CO), a poisonous gas you cannot see or smell. You
may be breathing CO even if you do not smell engine exhaust.

Pump operates in bypass mode
when spray gun trigger is not
pressed. When the temperature
inside the pump rises too high the
thermal relief valve (T, Fig. 9) will open
and release a gush of water in an
effort to lower the temperature inside
the pump. The thermal relief valve will
then close. If pump is left in bypass mode for more than two
minutes internal components of the pump can be damaged.
