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

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

Test your repair before regular operation

to

sure the problem is corrected.

6. If the sprayer

does

not operate properly, verify

that everything was done correctly. Also refer

to

the Troubleshooting Guide, pages

to

help

identify other possible problems and solutions.

WARNING

To reduce the risk of serious injury, including electric shock, DO NOT touch any moving parts or electrical parts with your fingers or a tool while inspecting

the

repair.

Shut

off

the sprayer and unplug it as soon as

you

complete the inspection.

Reinstall all covers, gaskets, screws and washers before operating the sprayer.

During operation, the motor and drive housing become very hot and could burn your skin if

touched. Flammable materials spilled on the hot,

bare motor could cause a fire or explosion.

Repair

1. Unscrew the spring retainer from the valve body. Remove the spring, washers and stemlball. Clean

any debris from the ball

or

seat area.

2.

If

replacing the gasket (42a) or seat (42b), pry out

the gasket.

NOTE:

Whenever the gasket (42a) is removed, re-

place it with a new one.

3.

Coat the O-ring (42d) with grease. Press the stem into the valve body. Install the spring, washers and spring retainer into the valve body.

4.

Place the seat (42b)

in

the valve body

so

the lapped side is toward the ball. Apply a small amount of grease to the new gasket (42a) and install it in the valve body.

NOTE

The gasket will protrude from the end of the valve until the valve is tightened into pump, which correctly seats the gasket.

Replacement

1. Apply a small amount

of

thread sealant (42e) onto the valve (42) threads. Tighten the valve into the pump manifold to 185 in-lb (21 Nm).

2. Lightly grease the face of the base (43) and install the base. Turn the stem
