WARNING

To reduce the risk of serious injury from from fluid
injection:

NEVER operate the spray gun with the tip guard
removed.

DO

NOT hold your hand, body, or a rag in front of
the spray tip when cleaning or checking a clogged
tip. Always point the gun toward the ground or

into a pail when checking to see if the tip is clear.

DO

NOT try to "blow back" paint; this

is

NOT an

air spray sprayer.

The tip guard alerts you to the risk and helps prevent

placing any part of the body close to the spray tip.
The tip guard also adjusts the vertical or horizontal
spray pattern. See page

12.

The tip guard holds a

reversing spray tip. The tip

is

in the spraying position

when the tip handle points forward. See Fig.

5.

Clean the front of the tip frequently during the day's
operation. First, follow the Pressure Relief Proce­dure on page 11.
