WARNING
INJECTION HAZARD
Spray from the gun, leaks or ruptured
components can inject fluid into your
body and cause extremely serious injury,
including the need for amputation. Fluid splashed in
the eyes or on the skin can also cause serious inju-
ry. See also page 3.
The tip guard alerts you to the risk of injection and
helps prevent placing any part of the body close to the
spray tip. The tip guard also adjusts the vertical or hori-
zontal spray pattern. See page 10. The tip guard holds
a reversing spray tip. The tip is in the spraying position
when the tip handle points forward. See Fig. 6.
Clean the front of the tip frequently during the day’s
operation. First, follow the Pressure Relief Proce-
dure
, left.
