Manual Accuracy  
Tool Description  
We are proud to provide a high-quality owners  
manual with your new tool!  
powder coating with the Model t25100 is a supe-  
rior alternative finishing process to wet painting on  
metal parts. a few of the advantages of powder  
coating are high durability, high-impact and stress  
resistance, and uniform control of finish.  
We made every effort to be exact with the instruc-  
tions, specifications, drawings, and photographs  
contained inside. sometimes we make mistakes,  
but our policy of continuous improvement also  
means that sometimes the tool you receive will  
be slightly different than what is shown in the  
manual.  
the powder coating process uses a dry, finely-  
ground polymer of various types and mixtures that  
is electrically charged and applied onto the metal  
workpiece through electrical attraction. after com-  
pleting the powder application, the finish must be  
cured (baked) in a dedicated electric oven.  
if you find this to be the case, and the difference  
between the manual and tool leaves you con-  
fused about a procedure, check our website for  
an updated version. We post current manuals and  
manual updates for free on our website at www.

SECTION 2: POWER SuPPLY  
a power supply circuit includes all electrical sys-  
Availability  
tems between the breaker box or fuse panel in the  
building and the t25100 control box. the power  
supply circuit used for this tool must be sized to  
safely handle the current drawn from the tool for  
an extended period of time. (if this machine is  
connected to a circuit protected by fuses, use a  
time delay fuse marked D.)  
Before using the Model t25100, consider the  
availability and proximity of the required power  
supply circuit. if an existing circuit does not meet  
the requirements for this tool, a new circuit must  
be installed. to minimize the risk of electrocu-  
tion, fire, or tool damage, installation work and  
electrical wiring must be done by an electrician or  
qualified service personnel in accordance with all  
applicable codes and standards.  
Note: The circuit requirements listed in this  
manual apply to a dedicated circuit—where only  
one tool or machine will be running at a time.  
If this tool will be connected to a shared circuit  
where multiple tools or machines will be running  
at the same time, consult a qualified electrician  
to ensure that the circuit is properly sized for safe  
operation.  
Electrocution, fire, or  
system damage may occur  
if system is not correctly  
grounded and connected  
to the power supply.  
for your own safety and protection of  
property, consult an electrician if you are  
unsure about wiring practices or electrical  
codes in your area.  
120v Circuit Requirements  
this tool is prewired to operate on a power supply  
circuit that has a verified ground and meets the  
following requirements:  
Nominal voltage ........................................120v  
Cycle..........................................................60 hz  
Phase........................................... Single-Phase  
Power Supply Circuit ......................... 15 Amps  
-7-  
Model T25100 (Mfg. Since 8/12)  
 
Improper connection of the equipment-grounding  
wire can result in a risk of electric shock. The  
wire with green insulation (with or without yellow  
stripes) is the equipment-grounding wire. If repair  
or replacement of the power cord or plug is nec-  
essary, do not connect the equipment-grounding  
wire to a live (current carrying) terminal.  
Grounding & Plug Requirements  
this system Must be grounded. in the event of  
certain malfunctions or breakdowns, grounding  
reduces the risk of electric shock by providing a  
path of least resistance for electric current.  
this system is equipped with a power cord that  
has an equipment-grounding wire and a ground-  
ing plug (similar to the figure below). the plug  
must only be inserted into a matching receptacle  
(outlet) that is properly installed and grounded in  
accordance with all local codes and ordinances.  
Check with a qualified electrician or service per-  
sonnel if you do not understand these grounding  
requirements, or if you are in doubt about whether  
the tool is properly grounded. If you ever notice  
that a cord or plug is damaged or worn, discon-  
nect it from power, and immediately replace it with  
a new one.

Grounding Prong  
We do not recommend using an extension cord  
with this tool. if you must use an extension cord,  
only use it if absolutely necessary and only on a  
temporary basis.  
5-15 PLUG  
Extension cords cause voltage drop, which may  
damage electrical components and shorten tool  
life. voltage drop increases as the extension cord  
size gets longer and the gauge size gets smaller  
(higher gauge numbers indicate smaller sizes).  
Neutral Hot

SECTION 4: OPERATIONS  
To complete a typical operation, the operator  
does the following:  
Operation Overview  
1. Examines the metal workpiece to make sure  
it is dry, clean, and suitable for powder coat-  
ing. sandblasting the workpiece is one effi-  
cient method of cleaning it.  
the purpose of this overview is to provide the  
novice operator with a basic understanding of how  
the tool is used during operation, so the tool con-  
trols/components discussed later in this manual  
are easier to understand.  
2. places the workpiece on a stable surface or  
securely hangs it in a dry, clean, and well-  
ventilated area. if using a hanger, make sure  
that it is made of clean metal and makes good  
metal-to-metal contact with the workpiece.  
Due to the generic nature of this overview, it is  
not intended to be an instructional guide. to learn  
more about specific operations, read this entire  
manual and seek additional training from expe-  
rienced operators, and do additional research  
outside of this manual by reading "how to" books,  
trade magazines, or websites.  
3. installs the proper scatter tip on the conduc-  
tor pole.  
4. attaches the grounding clip to the workpiece  
or hanger with good metal-to-metal contact.  
To reduce your risk of  
serious injury, read this  
entire manual bEfORE  
using this tool.  
5. puts on ansi-approved goggles/face mask,  
respirator, and clothing that protects the  
operator's skin.  
6. Fills the powder cup with approximately 2" of  
the selected powder.  
7. attaches the powder cup to the spray gun.  
Eye injuries, respiratory problems, or skin  
damage can occur while operating this tool.  
Wear approved safety goggles, respirator,  
non-insulating gloves, and anti-static cloth-  
ing to protect your skin.  
8. Connects the spray gun to a dry, clean, pres-  
surized air source between 10 psi and 30  
psi.  
9. Connects the control box to power and turns  
the system ON.  
10. aims the spray gun at the workpiece, then  
simultaneously steps on the foot switch and  
pulls the gun trigger to direct the powder  
cloud onto the workpiece.  
If you are not experienced with this type of  
equipment, WE STRONGLY RECOMMEND  
that you seek additional training outside of  
this manual. Read books/magazines or get  
formal training before beginning any proj-  
ects. Regardless of the content in this sec-  
tion, Grizzly Industrial will not be held liable  
for accidents caused by lack of training.  
11. Maintain an even powder thickness of approx-  
imately 2mm.  
12. When finished, turns the system OFF, and  
immediately grounds the conductor pole to  
the grounding clip to discharge the gun's  
electrical charge.

-12-  
Model T25100 (Mfg. Since 8/12)  
 
use a side-to-side overlapping pattern when  
spraying. Most powder products require a  
coating of approximately 2mm. Check the  
powder manufacturer's specifications and  
practice attaining the correct thickness on a  
scrap workpiece.  
Operational Points  
Adhere to the following points for the best  
powder coating results:  
the workpiece Must be clean of debris,  
paint, or other non-metal material. Depending  
upon the application, cleaning may be as  
simple as using mineral spirits and clean  
rags, or it may require a much more compli-  
cated "pre-treament" process, such as sand-  
blasting.  
you Must “cure” the workpiece to complete  
the powder coating process. the curing oven  
must have good ventilation. poor air circula-  
tion can cause discoloration or hazing.  
fumes from the curing process are poison-  
ous! Make sure the curing oven is well-ven-  
tilated. use a dedicated electric oven that  
will NOT be used for cooking food.  
obtaining good powder coating results  
depends on many variables—workpiece pre-  
treatment, powder chemical composition,  
method of spraying, curing procedure, etc.  
read books, use online resources, or talk to  
professionals to gain an understanding what  
is required for your operation.  
Follow closely the powder manufacturer's  
directions for curing. under-curing can result  
in poor physical qualities and over-curing can  
change the color.  
use only high-quality powder coatings.  
investigate the many powder options on the  
market and choose the one that best suits  
your application.  
always maintain clean powder cups, spray  
gun, and work area. Contamination of pow-  
der products by debris or other powder mate-  
rial can produce unexpected results.  
use only pressurized air that is clean, dry,  
and free from oil.  
some orange peel effect may be unavoid-  
able. if this happens, wet-sand the workpiece  
with 400 grit sandpaper, thoroughly dry the  
workpiece, and repeat the coating process.  
Make sure the system ground clip is firmly  
secured to the workpiece or hanger with good  
metal-to-metal contact.  
to begin spraying, depress the foot switch  
and spray gun trigger simultaneously. the  
foot switch enables power to the gun conduc-  
tor pole, which electrically charges the dust  
as it leaves the gun. the spray gun trigger  
allows air to flow through the powder cup and  
gun to send the powder onto the workpiece.  
to remove slight imperfections, buff the  
workpiece with a loose buffing wheel and  
white rouge compound.  
Exposure to powder coat-  
ing materials can cause eye,  
lung, or skin injury. Always  
wear ANSI-approved gog-  
gles, NIOSh-approved res-  
pirator, and wear clothing  
that will protect your skin.  
use the air pressure regulating valve and  
powder flow regulating screw to control the  
flow of powder through the spray gun.  
Experiment with the scatter tips to gain an  
understanding of the effects attained with  
each tip.

use clean metal material for workpiece hang-  
ers. this will ensure that the hanger is  
grounded with the workpiece.  
Workpiece  
Preparation  
Scatter Tips  
The powder coating system is designed to  
ONLY operate on solid, electrically-conduc-  
tive metal workpieces.  
the Model t25100 ships with three scatter tips  
with diameters of 12", 34", and 1" (see figure 9).  
follow these workpiece preparation guide-  
lines for the best results:  
thoroughly clean the workpiece of paints or  
other finishes, residue left by cleaning solu-  
tions, debris, dust, and any other foreign  
material. Depending upon the application,  
additional pre-treatment steps may be neces-  
sary.  
Make sure the workpiece is completely dry.  
attach the grounding clip (see figure 8) to  
the workpiece or hanger with a good metal-  
to-metal contact at a point where the pow-  
der will not be applied. this will provide a  
negative electrical attraction for the charged  
power.  
figure 9. included scatter tips.  
the scatter tips thread onto the conductor pole  
(see figure 10) and produce different spray pat-  
terns. Experiment with a scrap workpiece to gain  
an understanding of the effect that each tip pro-  
duces.  
Note: Wipe the tips clean of powder before stor-  
ing them.

Make sure the workpiece is not touching any  
other grounding source other than the pow-  
der coating system ground.  
to reduce the risk of electrical shock from  
workpiece contact, position or hang the  
workpiece so that it does not need to be  
re-positioned during the powder coating pro-  
cess.

5. Connect the tool to the air supply (but not  
to power) and use the spray gun trigger to  
send air through the gun to make sure any  
residual powder from the last operation is  
cleared away.  
The spray gun conductor  
pole may be electrically  
charged. Always discon-  
nect the system from power  
and ground the conductor  
pole to the system ground-  
ing clip before making con-  
tact with conductor pole to  
reduce the risk of electric  
shock or dust explosion  
from electrostatic sparks.  
6. remove the powder cup from the spray gun  
and fill it with up to 2" of powder.  
Note: Leaving space in the powder cup  
allows the powder to circulate into a fine dust  
when the air is applied.  
7. Make sure the gasket is in place inside the  
mounting cap, then turn the gun upside down  
and thread the powder cup onto the mounting  
cap (see figure 12).  
Powder Cups  
During operation, air circulates inside the pow-  
der cup to produce a fine dust, which is then fed  
through the spray gun and onto the workpiece.  
To fill and attach the powder cup:  
1. DisConnECt tool FroM poWEr!  
2. put on eye, lung, and skin protective gear.  
figure 12. powder cup installed.  
3. Make sure the powder cup, gasket, and  
mounting cap components (see figure 11)  
are dry and clean of any powder or debris.  
Curing  
Mounting  
Cap  
Curing the powder coating is a process that melts  
the powder into an even finish that adheres to the  
workpiece. this is done with a dedicated electric  
oven that is not used for any other purpose.  
Follow the powder coat manufacturer's recom-  
mendations for curing temperature and length of  
time to produce good results.

The powder coating will NOT adhere to the  
workpiece unless it is properly cured in a  
dedicated electric oven. follow all recom-  
mendations made by the power coat manu-  
facturer for properly curing their product.
