penetrated the skin! DO NOT TREAT AS A SIMPLE CUT!!
• High pressure hoses and fuel lines should be inspected daily for signs
of wear. If evidence of failure exists, promptly replace all suspect
hoses and fuel lines to prevent the possibility of injury from the high
pressure spray. If a hose or fitting is leaking, NEVER PLACE YOUR
HAND DIRECTLY ON THE LEAK.
• NEVER operate the gun with the trigger wired in the open position.
To prevent accidental discharge, the trigger gun should be securely
locked when not in use.

off the unit and trigger the gun to release trapped pressure. (Even af-
ter you shut off the unit, there is high pressure water left in the pump,
hose and gun until you release it by triggering the gun.)
