WARNING
INJECTION HAZARD
Spray

Do not point the gun at anyone or at any part of the body
Do not put your hand or fingers over the spray tip.
Do not stop or deflect leaks with your hand, body
Do not “blow back” fluid; this is not an air spray system.
Always have the tip guard and the trigger guard on the gun when spraying.
