INTRODuCTION
Manual Accuracy
Tool Description
We are proud to provide a high-quality owner’s
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.
grizzly.com.

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.

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.

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.

•
•
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

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 1⁄2", 3⁄4", 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.

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.

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.

Cup
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.
