10. Maintain tools with care. Keep  
tools sharp and clean for better and  
safer performance. Follow instruc-  
tions for lubricating and changing  
accessories. Inspect tool cords peri-  
odically and, if damaged, have them  
repaired by an authorized technician.  
The handles must be kept clean, dry,  
and free from oil and grease at all  
times.  
16. Replacement parts and acces-  
sories. When servicing, use only  
identical replacement parts. Use of  
any other parts will void the warranty.  
Only use accessories intended for  
use with this tool. Approved accesso-  
ries are available from Harbor Freight  
Tools.  
17. Do not operate tool if under the in-  
fluence of alcohol or drugs. Read  
warning labels on prescriptions to  
determine if your judgment or reflex-  
es are impaired while taking drugs. If  
there is any doubt, do not operate the  
tool.  
11. Disconnect power. Unplug trans-  
former when not in use.  
12. Avoid unintentional starting. Be  
sure the switch is in the Off position  
when not in use and before plugging  
in. Do not carry any tool with your  
finger on the trigger, whether it is  
plugged in or not.  
18. use proper size and type extension  
cord. If an extension cord is required,  
it must be of the proper size and type  
to supply the correct current to the  
tool without heating up. Otherwise,  
the extension cord could melt and  
catch fire, or cause electrical damage  
to the tool. This tool requires use of  
an extension cord of 0 to 10 amps  
capability (up to 50 feet), with wire  
size rated at 18 AWG. Longer exten-  
sion cords require larger size wire. If  
you are using the tool outdoors, use  
an extension cord rated for outdoor  
use (signified by “WA” on the jacket).  
13. Stay alert. Watch what you are do-  
ing, use common sense. Do not oper-  
ate any tool when you are tired.  
14. Check for damaged parts. Before  
using any tool, any part that ap-  
pears damaged should be carefully  
checked to determine that it will oper-  
ate properly and perform its intended  
function. Check for alignment and  
binding of moving parts; any broken  
parts or mounting fixtures; and any  
other condition that may affect proper  
operation. Any part that is damaged  
should be properly repaired or re-  
placed by a qualified technician. Do  
not use the tool if any switch does not  
turn On and Off properly.  
19. Maintenance. For your safety,  
service and maintenance should be  
performed regularly by a qualified  
technician.  
20. The warnings, cautions, and instruc-  
tions discussed in this instruction  
15. Guard against electric shock.  
Prevent body contact with grounded  
surfaces such as pipes, radiators,  
ranges, and refrigerator enclosures.  
Never touch the object being coated  
with one hand while spraying with the  
other.

Connect Air Hose  
8. Setup a dedicated electric oven (with  
adequate ventilation) for curing the  
coated objects with a temperature  
capability from 300 to 500° F.  
PREPARATION  
1. Setup an air supply with an air pres-  
sure regulator and moisture trap (do  
not use an inline air oiler). The air  
compressor must provide an air pres-  
sure of 20 to 40 PSI.  
WARNING: Never use a gas oven, the  
fumes from curing can be explo-  
sive. Never use a home oven that  
is also used for food. Contamina-  
tion of food will occur.  
2. Select a safe location for spraying  
and curing with:  
- adequate lighting  
- active ventilation  
- no flame or ignition source  
- an area dry, clean, and covered --  
free of flammable material  
9. Clean the object to be powder coated  
of any old coatings, rust, grease and  
oil.  
OPERATION  
3. Have an activated charcoal filter  
respirator availability for use when  
curing.  
1. Place or hang the cleaned object to  
be coated near the ventilation sys-  
tem.  
4. Have disposable dust masks avail-  
able for use when powder spraying.  
If the object has grooves or recesses,  
position the object so that gravity as-  
sists the powder mist to fall into the  
grooves or recesses.  
5. Have a pair of vinyl gloves for  
use when handling the power and  
sprayed objects.  
2. Connect the Disposable Moisture  
Separator (8) to the Spray Gun (2).

3. Unscrew the Cup (4) from the Spray  
Gun (2) and fill with up to two inches  
of coating powder (not supplied).  
- Turn the Cup upside down and  
place on a clean piece of paper.  
- Put on a pair of disposal vinyl  
gloves.  
6. Turn ON the Power Switch (17) of the  
Control Box (1).  
7. Turn ON the compressor and adjust  
the air pressure to between 20 and  
40 PSI.  
This can be done at the compressor  
if it has a pressure value, or on the  
Spray Gun by adjusting the Pressure  
Reducer Valve (18).  
- Open the powder coating container,  
and using a piece of clean paper as a  
guide,  
pour the powder into the Cup.  
- Turn the Spray Gun upside down  
and screw the Cup back into the  
Spray Gun.  
8. Press the Spray Gun Trigger (7) and  
Pedal Switch (11) at the same time  
and test the spray pattern on a piece  
of scrap metal.  
- Reseal powder container.  
The Trigger controls the air and pow-  
der flow. The Pedal Switch controls  
the electrical charge. If the pattern  
is too small or too large, change the  
Scatter Tip (12). Remember that the  
pointed end of the Scatter Tip faces  
toward the Spray Gun and screws on.  
The spray pattern can also be adjust-  
ed using the Regulating Screw (14):  
loosen to expand the pattern, tighten  
to reduce the pattern size.  
Note: Only use the provided cups with  
this system. Other cups will not seal  
properly.  
4. Connect the 1/4 inch air hose to the  
Disposable Moisture Separator (8).  
5. Attach the Ground Clip (10) to the  
metal object being coated.  
Securely attach the Ground Clip to  
an area which is not being coated if  
possible. This connection is abso-  
lutely necessary to draw the electri-  
cally charged (power) particles to the  
metal object.  
9. When coating, keep the Spray Gun  
approximately eight inches from the  
metal object.  
- Point the Spray Gun toward the ob-  
ject at different angles to guarantee  
that all areas are coated.

- When completed, the object should  
be completely coated with a dull,  
opaque coat of powder.  
15. When cured, turn the oven OFF and  
open the oven door slightly to allow  
the object to cool gradually before  
removing.  
10. When finished spraying:  
- remove your foot from the Pedal  
Switch (11),  
When the object is cooled too rapidly,  
a dull finish may result.  
- press the Control Box Power Switch  
(17) to the OFF position,  
Process Tips  
- unplug the Control Box power cord  
from the electrical outlet.  
1. To remove an orange peel effect after  
curing, wet-sand the object with 400  
grit sandpaper, dry, and repeat the  
coating process. Over-powder coat-  
ing can cause this effect.  
WARNING: The Spray Gun is still elec-  
trically charged. Discharge Con-  
ducting Pole before touching or  
you could be shocked.  
2. Polish with traditional paint polishes.  
11. Touch the Conducting Pole (9) to the  
Ground Clip (10) to discharge any  
residual electricity.  
3. Lightly buff with a loose wheel and  
white rouge compound to remove  
imperfections.  
12. Wipe the Scatter Tip off with a clean  
cloth.  
4. Thoroughly clean the Cup before  
changing powders.  
Some powders are made from poly-  
ester, while others are made from  
polyurethane. A mixture of both can  
cause pitting of the coated object.  
13. Place the activated charcoal respira-  
tor over your face mouth and hose.  
WARNING: The fumes produced dur-  
ing curing are hazardous to your  
health. Do not breathe the fumes.  
5. Porous metal objects may need a  
thorough cleaning with a brush and  
pre-painting cleaning solutions.  
14. With the oven preheated to the de-  
sired temperature (300 to 500 de-  
grees F), place the object on the  
oven rack, close the door, and turn  
the ventilation system ON.  
6. If the powder starts to buildup in one  
place, blow off with light air pressure.  
Moisture in the air will cause pow-  
der buildup. Replace the Disposable  
Moisture Separator (8).  
- Typical curing time is 15 minutes.  
Check the Powder Coating container  
for recommended curing time and  
temperature.  
- If the object is large, curing may  
take more time.  
- The power coating should melt to  
a smooth, gloss finish all over the  
object.  
- Check the curing object often to  
prevent over-curing which can cause  
roughness to the surface.  
7. Poor disbursement can be caused by  
low air pressure. Adjust the air pres-  
sure or replace the Disposable Mois-  
ture Separator. The Cup should have  
at least one inch of powder during  
coating.  
8. Use automotive paint remover to  
remove a cured coating.
