The spray tip should not be attached to your spray gun

when purging your spray hose.

must be grounded while purging (see warning below).

Danger

Keep hands clear from uid stream. Ground the gun

by holding it against the edge of a metal container

while ushing. Failure to do so may lead to a static

electric discharge which may cause a re.

Danger

If the PRIME/SPRAY knob is still on SPRAY, there will

be high pressure in the hose and spray gun until the

PRIME/SPRAY knob is turned to PRIME.

Figure12-AttachingtheSprayTip

Danger

POSSIBLE INJECTION HAZARD. Do not spray

without the tip guard in place. Never trigger the

gun unless the tip is in either the spray or the unclog

position. Always engage the gun trigger lock before

removing, replacing or cleaning tip.

 1. Lockthesprayguno.

2. Thread the tip guard onto the gun.

When attaching the tip guard to the gun, align the tip

guard as shown in gure 12 (a), then tighten by hand

(b).

When nished spraying, perform Pressure Relief

Procedure.

If you expect to be away from your spray project for

more than 1 hour, follow the Short Term Cleanup

procedure described in the Cleanup section of this

manual.

Figure 14 - Practice

1. Be sure that the paint hose is free of kinks and clear of objects

with sharp cutting edges.

 2a. Ifyouaresprayingthickermaterials,turnthePRIME/SPRAY

knob to MAX SPRAY.

 2b. Ifyouaresprayingthinnerorlighterbodiedmaterials,turnthe

PRIME/SPRAY knob to SPRAY (1).

The paint hose should stien as material begins to ow

through it.

 3. Unlockthespraygun.

4. While pointing the gun at a piece of scrap wood or cardboard,

triggerthesprayguntobleedairoutofthehose.

will be too light. If the pressure is set too low, tailing will

appear or the paint will spatter out in blobs rather than in a

nespray(B).

Figure15-UncloggingtheSprayTip

If the spray pattern becomes distorted or stops

completely while the gun is triggered, follow these

steps.

Danger

Do not attempt to unclog or clean the tip with your

nger. High pressure uid can cause injection injury.

1. Release the trigger and lock the gun o. Rotate the reversible

tip arrow 180º so that the point of the arrow is toward the rear

of the gun (see gure 15).

Under pressure, the spray tip may be very dicult to

turn. Turn the PRIME/SPRAY knob to PRIME and

trigger the gun. This will relieve pressure and the tip

will turn more easily.

 2. Turntheprime/sprayknobtospray.

3. Unlock the gun and squeeze the trigger, pointing the gun at

a scrap piece of wood or cardboard. This allows pressure in

thesprayhosetoblowouttheobstruction.Whenthenozzle

is clean, material will come out in a straight, high pressure

stream.

4. Release the trigger and lock the gun o. Reverse the tip so

the arrow points forward again. Unlock the gun and resume

spraying.
