5. Put drain tube in a pail. Turn prime valve

down. Leave prime valve in down (drain)

position until you are ready to spray

again.

6. If you suspect the spray tip or hose is

clogged or that pressure has not been

fully relieved:
a. VERY SLOWLY loosen the tip

guard retaining nut or the hose end

coupling to relieve pressure

gradually.

b. Loosen the nut or coupling

completely.

c. Clear hose or tip obstruction.

Trigger Lock

Always engage the trigger lock when sprayer

is stopped to prevent the gun from being

triggered accidentally by hand or if dropped

or bumped.
