Operation

1. Begin

spraying.

Always keep

the gun at

right angles

to the work

(See Figure 8).

2. Keep the

nozzle about

6 to 9 inches

from the

work surface

throughout

the stroke

and always

keep the gun

in motion while spraying. Stopping

gun movement in mid-stroke will

cause a build up of paint and result

in runs. Do not fan the gun from

side to side while painting. This

will cause a build-up of paint in

the center of the stroke and an

insufficient coating at each end (See

Figure 9).

3. Trigger the gun properly. Start the

gun moving at the beginning of

the stroke BEFORE SQUEEZING

THE TRIGGER and release the

trigger BEFORE STOPPING GUN

MOVEMENT at the end of the

stroke. This procedure will feather

(blend) each stroke with the

next without showing overlap or

unevenness (See Figure 10).

4. The amount of paint being applied

can be varied by the speed of the

stroke, distance from the surface

and adjustment of the fluid control

knob.

5. Overlap strokes just enough to

obtain an even coat (See Figure 11).

NOTE: Two thin coats of paint will yield

better results and have less chance of

runs than one heavy layer.

6. Use a piece of cardboard as a shield

to catch overspray at the edges of

the work to protect other surfaces.

Use masking tape to cover other

areas if needed.

Instructions

DAILY CLEAN-UP

Local codes may require specific

cleaning methods and equipment.

Follow local codes and paint

manufacturer’s recommendations for

the use and disposal of spray materials

and solvent.

Clean spray gun

immediately after

use. Paint and other materials dry

quickly in the small passages rendering

gun useless due to the difﬁculty of

removing hardened paint from the

passages inside the gun.

NOTE: In the instructions below, the

use of the word “solvent” refers to the

specific solvent for the material used

(example: lacquer thinner for lacquer,

etc.).

1. Remove and empty the canister;

then rinse with a solvent

recommended for the paint or other

material used.

2. Refill canister with clean solvent

and attach to the gun. Spray solvent

through the gun while shaking

the gun vigorously. Wipe the gun

exterior with a solvent soaked rag.

Repeat until the gun is clean.

3. Remove the air cap and soak in

solvent until clean. Use a small brush

for stubborn stains if necessary.

Toothpicks or small brushes may be

used to clean air passages; however,

NEVER USE METAL OBJECTS

TO CLEAN PRECISELY DRILLED

PASSAGES. DAMAGED PASSAGES

WILL CAUSE IMPROPER

SPRAYING.

4. Clean gaskets with a solvent soaked

rag. To prevent equipment damage,

DO NOT IMMERSE GASKETS OR

SPRAY GUN BODY IN SOLVENTS.

5. After using water to clean out water

based paints or materials, spray

mineral spirits through the gun to

prevent corrosion.

6. Use a non-silicone oil on all moving

parts when reassembling. Use

Vaseline

or light grease on all

threaded connections prior to

storage.

7. Clean and flush gun thoroughly

to neutralize any contaminants

corrosive to the spray gun.

PERIODIC CLEAN-UP

Due to improper cleaning and paint it

may be necessary to inspect and clean

the internal parts and the gun body.

1. Examine openings in air cap and

fluid tip. If clogged, remove any

o-rings and soak the air cap or fluid

tip in solvent.

2. A brush or toothpick or something

similar may be used to dislodge the

dried paint from holes and passages.

NEVER USE METAL OBJECTS

TO CLEAN PRECISELY DRILLED

PASSAGES. DAMAGED PASSAGES

WILL CAUSE IMPROPER

SPRAYING.

3. Remove and check the fluid needle

for excessive wear at the tip and

straightness.

IMPORTANT: If the needle tip is worn
