2. Maxi-Miser® Spray Finishing Systems
CONGRATULATIONS!! You have just purchased the Maxi-Miser 3000 PRO HVLP
turbo spray system, the finest spray system available to spray cars, boats and
airplanes. You are about to enjoy the great benefits of the Maxi-Miser™ system. Our
designs are the result of over 50 years of experience in manufacturing HVLP turbo
spray systems and spray guns. We have progressively worked and consulted with
professional spray finishers in your industry to bring you this versatile, well-
engineered tool.
Whether you are new to spray finishing, you have spray finished before, or are just
new to Maxi-Miser spray systems; there are some basic spray finishing guidelines
that will help you to achieve the best results and optimum success from your new
equipment. Reading this information carefully and following these simple steps will
ensure that you get the best performance and results from your new TrueHVLP™
spray system.
Check the contents of your box. The following are included:
(1) Maxi-Miser® 3000 Turbo Unit (1) Wrench
(1) PBC-GTO™ Clearcoat Spray Gun (1) Spray Gun Lube
(1) PBC-GTO™ Basecoat Spray Gun (1) Blow-off Tool
(1) PBC-GTO™ Primer Spray Gun (1) Cleaning Brush
(1) 37’ Flex-Air Hose (1) Electric Cord
(1) Instruction Manual (1) Booth Installation Kit
3. How Your Maxi-Miser™ Turbo Spray System Works
We have designed 3 PBC-GTO spray guns for spraying various automotive finishes. Each of the spray guns are
designated with a different colored handle to help you keep track of which gun is for what material.
The PBC-GTO spray guns with the GREEN handle are for spraying Base coats. Most
basecoats spray very nicely with the 0.8mm needle and nozzle set up along with the B-HS
air cap. This is the standard size for the basecoat spray gun.
The PBC-GTO spray guns with the GREY handle are for spraying Primers. Most primers
spray nicely using a 1.0mm needle and nozzle set up along with the B-HS air cap. This is
the standard size in the primer spray gun.

Page | 4
The PBC-GTO spray guns with the matte brown spray head and the BLACK handle are
for spraying clear coats. Depending on if you are spraying spot repairs or larger areas
you could have one of two different size needles, nozzles or air caps. For spot repairs
we recommend the 0.5mm with our “CC” air cap. For spraying 2 or more panels or large
areas we recommend the 0.8mm needle and nozzle with the B-HS air cap.
Your Maxi-Miser® system has three components: the turbo unit (your air supply) (1), spray gun (2) and air hose (3).
The turbo unit, when connected to single phase 240 volt power supply and with the on/off switch in the “on” position,
provides a continuous source of clean, warm, dry, High Volume Low Pressure (HVLP) air. The air hose connects the
turbine unit to the spray gun. Air flows through the hose to the nozzle of the specially designed TrueHVLP™ spray gun.
Atomization of the coating is achieved when the air mixes with the stream of fluid passing through the tip/nozzle. This
low-pressure atomization principle achieves minimum misting (overspray) to the spray environment and maximum
savings in paint.
4. How Your PBC-GTO Spray Gun Works
Your Apollo Maxi-Miser® PBC-GTO™ spray gun operates like a typical compressed air spray gun with some minor
differences. The cup on your PBC-GTO™ spray gun is pressurized through the air feed tube. This will help deliver fluid
to the nozzle and produce a larger fan pattern. It is possible to use the PBC-GTO™ spray gun without the air feed tube
connected, but only with certain types of paints and using larger needle and nozzle sizes. You will notice a much
smaller fan pattern when using the spray guns without the air feed tube connected. It is always recommended to use
the spray gun with the air hose attached.
When the material adjustment screw is opened and the trigger pulled back, fluid flows through the nozzle mixing with the
air flow delivered from the air cap and projects a fine atomized mist to your work piece. You can adjust the fluid flow by
opening or closing the material adjustment screw to your liking. The fan adjustment ring is located at the front of the spray
gun. Locate the adjustment marks on the side of the spray gun body. Turn the fan control ring up to achieve a smaller fan
or down to achieve a larger fan.

5. Preparing to Use Your Maxi-Miser® Turbo System
Connect the male end of the air hose to the turbo system. Pull back the
spring loaded quick disconnect coupler and insert the male connector on
the air hose into the turbine connector. Release the ring. Your air hose
will be locked into place. To release the air hose, pull back on the spring-
loaded quick coupler ring with your fingers and pull.
Connect female end of air hose to your spray gun using this same procedure.
Plug the power cord into a single phase 240 volt outlet that is properly installed and grounded in accordance with local
codes and ordinances. Your Maxi-Miser® system is rated for 240 volts. Plugging the turbo system into the wrong
voltage will damage the motor and void your warranty.
NOTICE!
Do not cover or enclose the turbine. It is important to draw cool/ambient air through the unit for optimum
performance. Avoid placing the turbine in a warm environment or in direct sunlight. Do not spray in ambient
temperatures above 90 degrees. If you want to be able to spray in hotter temperatures, we recommend placing
a fan in front of your turbine to help it pull in cool air or place it in an air conditioned environment.
6. Setting up Your PBC-GTO Spray Guns
Good quality results with your TrueHVLP™ spray finishing equipment are a combination of careful preparation of your
project, a proper spraying environment, a basic knowledge of the coatings you will be using and how these coatings
work with your Maxi-Miser™ finishing equipment.
Your PBC-GTO spray guns come with a 600cc gravity feed cup assembly standard. Some minor assembly is required:
1. Screw the cup to the material connector on the top of the spray gun
body. Tighten with (spanner) wrench only as shown in the “correct”
picture.

Page | 6
DO NOT tighten by holding the cup in the “incorrect” picture.
NOTE: Failure to tighten correctly can result in damaging the seal at the base of the
cup.
3. Screw the air feed connector (A5211N) onto the side of the spray gun body.
4. Push the air feed tube onto the air feed connector
5. Push the other end of the air feed tube onto the cup lid connector.
NOTE: Make sure you attach the air feed tube so that the black end of the air valve is pointing
towards the cup lid as shown in the illustration.
NOTE: Above the non-return valve you will see an air relief valve. The purpose of this valve it
to release pressure from the cup prior to opening the cup lid to prevent paint splatter. To
release the pressure all you need to do is turn the air relief valve.
6.1 Operating your PBC-GTO Spray Gun
The PBC-GTO spray gun has a unique and simple fan pattern control. Locate
the Fan Adjustment Ring in the front of the spray gun. Turn the spray gun on its
side and notice the fan size indicator stamped into the spray head casting, just
to the right of the fan adjustment ring. You will notice that there is a (-) sign at
the top and a (+) sign at the bottom with two arrows indicating the direction of
rotation. Rotating the ring UPWARD will begin to reduce the size of the fan
pattern until the pattern is round. Rotating the ring DOWNWARD will provide a

Page | 7
full, open, wide pattern. (Relative to the distance the spray gun is held from the
work surface).
To adjust the direction of the fan pattern, rotate the air cap ears (Fig. 2) clockwise to either a vertical or horizontal
position as noted in the diagram. This will provide your vertical or horizontal fan pattern.
Spray Patterns
Fig. 1 Use this position when spraying across from side to side
Fig. 2 Use this position when spraying from top to bottom
Fig. 3 Use this position for spotting small objects, corners and sharp angles and touch up
Install the appropriate fluid nozzle, needle assembly and color-coded air cap (A, B, C or D) for the viscosity of the fluid
being sprayed. See Chart B for recommendations. Prepare your coating as you would normally, (Thinning if necessary).

6.2 Spray Gun Technique
Connect the appropriate air hose to the spray gun. Begin turning the material adjustment screw (#19) anti or
counterclockwise 1 – 2 full turns. Look at the size of the fluid pattern and flow volume. Adjust before applying material to
your substrate. If you have too much fluid flow, turn the material adjustment screw clockwise. If you do not have enough
fluid flow, adjust the material adjustment screw anti/counterclockwise. Hold spray gun 4” – 6” (10cm-15cm) from your work
surface depending on the size of your substrate. Closer is generally preferred for highest efficiency and the least amount
of overspray. Follow the proper spray technique as outlined in the spray technique diagram. You can increase or decrease
the fluid flow as desired as well as the distance from your work surface as necessary. Adjust the Fan Adjustment Ring as
desired.
Like any skill, practice makes perfect. Never try to rush the spray finishing process. Learn the characteristics of the coating
you will be spraying. Build up layers of material. Sand between coats and allow proper drying time between applications.
Here are some general guidelines for effective spray finishing:
1. Remember to always keep the distance between the spray gun and the surface the same when moving across
your work, (or up and down) called a “pass”. Do not rotate or turn your wrist from side to side. See Chart C below.
2. Move the spray gun across your work from end to end.
3. Be sure to maintain the same speed of movement. This ensures an even application of coating.
4. At the end of a “pass” always release the trigger. To continue, spray in the opposite direction and overlap your
previous coat by 50-75%
5. When finished you should have an even wet coat on your work. If you have dry spots, you have overlapped too wide.
If you have heavy or wet spots, you have overlapped too much or moved the spray gun too slow.

Page | 9
6. When spraying cars start at the top and work down. This will stop any overspray from landing on your previously
sprayed panels.
7. Try to spray the hard to reach and underneath surfaces first.
Common sense and some forethought will prevent errors. Remember, that a light wet film will generally produce better
results than a heavy wet coat. When spraying a vertical surface, it is advisable to apply a thin/light “tack” coat first, followed
by a normal light wet coat. This technique will help prevent “runs” and “sags”.
Chart C
Spray Gun Technique
When using your Spray Gun, you control five variables:
1. Fluid flow.
2. Distance of the spray gun from your work. 4”-6” (10-15cm) is ideal. Closer if necessary.
3. Pattern direction (vertical, horizontal and round).
4. Speed of application.
5. Fan pattern size.
NOTE: Items 1, 2, and 4 directly relate to each other.
6.3 Cleaning Your PBC-GTO Spray Gun
After you are finished spraying, follow these instructions to clean your PBC7600-GTO spray gun(s):
6.3.1 Partial Cleaning
Cleaning your PBC-GTO spray gun does not have to be a difficult task. Often, when spraying a variety of clearcoats,
thorough rinsing and wiping of basic parts is all that may be necessary. The basic steps below are for simple and easy
cleaning of your PBC-GTO spray gun.
1. Empty any unused material (paint) from the cup and wash out any residue with an appropriate cleaner compatible with
the coating, or water if using water-based material. Partially fill the cup with cleaner and spray through the gun to flush out
the material passages.
2. Remove the Air Cap (#2) and clean. Ensure that all the air holes in the air cap are clean.
3. Using a brush and solvent, remove any paint deposits on the outer surface of the tip/nozzle (#3). (Apollo FS1900 cleaning
brush kit recommended).
4. Unscrew and remove the Material Adjustment Screw (#19).

Page | 10
5. Remove the needle spring (#20).
6. Pull the trigger and then pull the needle (#21) out through the back of the spray gun.
7. Remove the fluid nozzle (#3) with the wrench (spanner) provided.
8. Clean both fluid nozzle and needle assembly using cleaner or water and a brush.
9. Reassemble following the instructions in the next section for thorough cleaning. Make sure to oil the needle spring
(#20), the Air Valve Stem (#14) and the Gland Seal (#24) to prevent the needle from sticking.
10. To adjust the Gland nut (#23) tighten slightly until you feel tension on the needle. Do not over tighten the gland nut or
the needle will stick. Do not under tighten the gland nut or the gland seal will leak.
11. Check the Cup Top Gasket and replace it if damaged. Always seat the cup top gasket flat in the cup groove. Failure to
do this will allow the cup to drip and impair the spray pattern due to loss of cup pressure.
6.3.2 Thorough Cleaning
To further disassemble the spray gun now that you have already removed the air cap ring (#1), air cap (#2), fluid nozzle
(#3) and needle (#21), locate the air cap seal (#4). To remove the air cap seal, lay the spray gun on its side.
1. Locate the small groove on the air cap seal. You can rotate the groove to a comfortable
position for removal. (3 o’clock or 9 o’clock).
2. Place the flat tip of the wrench (spanner) in the air cap seal groove. Push in and pry up until the air cap seal pops out.
(Clean if necessary).
3. Remove the air distributor (#6) and clean if necessary.

Page | 11
4. Remove the fan adjustment ring (#8) and air distributor plate (#7). The air distributor
plate is attached to the ring. These two pieces are separate. Clean them both if
necessary.
Note: Make sure you reassemble the two pieces correctly or you will only
get a round fan pattern.
5. Remove the fan adjustment seal (#9). Clean if necessary.
6.3.3 Re-Assemble the Spray Gun
1. Insert the fan adjustment seal (#9). Place back down with thin edge going down into the gun head.
2. Insert the fan adjustment ring and air distributor
plate. (#7 and #8). If you have
separated these two pieces it is critical that the white
air distributor plate is correctly re-inserted into the fan
adjustment ring. Note that the open slots on the air
distributor plate must be visible through the holes of the
fan adjustment ring.
3. Using the back end of the needle, move the distributor plate so that the round
screw hole is at the 5 o’clock position. DO NOT put the distributor plate and fan
adjustment ring together as shown in the picture marked “incorrect”.
4. Place the Air Distributor (#6) on top of the paired fan adjustment ring and Air
Distributor plate.
5. Align the screw hole in the Air Distributor with he holes in the fan adjustment ring
6. Holding the head of the spray gun facing you, place the Air Distributor Assembly onto
the body of the spray gun aligning the round hole with the locating pin in the spray gun
body at the 5 o’clock position.
7. Screw the fluid nozzle (#3) back onto the spray gun, finger tight. Rotate the fan
adjustment ring to be sure it rotates freely and easily. Tighten the nozzle slightly more with
thewrench(spanner). Rotate fan adjustment ring again. Do not over tighten the fluid nozzle
as it will stop the fan adjustment ring from rotating. If too tight, back off slightly. Be sure
that the fluid nozzle is not too loose, or leaking will occur.

Page | 12
8. Insert the air cap seal (#4). To insert, observe both sides of the seal. One side should
have three small circles. This side goes toward the spray gun. Snap the air cap seal onto
the air distributor (#6).
9. Push the needle (#21) back into the spray gun.
10. Insert the Needle Spring into the Material Adjustment Screw (#19).
11. Install the Material Adjustment Screw with Needle Spring (#20).
12. Install air cap and air cap ring. Spray gun is now re-assembled and ready to use.
NOTE: Periodically, use Apollo lubricant to lubricate the air valve bushing as
shown.
Pressure will remain in the spray cup when the unit is off. If you pull the
trigger back, a stream of fluid will flow. To prevent accidents, turn material
flow screw clockwise until it is completely closed. The trigger is now locked
in the closed position.
To relief the cup pressure prior to opening the cup use the twist connector located between the check
valve and the cup lid. Undo the connector and the air pressure will exhaust through the tube. If you
don’t relieve the air pressure prior to opening the lid on the cup, paint can fly out and down the side of
the cup.

7. Get to Know Your Maxi-Miser® Turbo Spray System
Handi-Hold™ Spray Gun Docking Station:
Your Maxi-Miser® turbo spray system comes equipped with Four (4) Handi-
Hold™ Spray Gun Docking Stations (Figure A). This feature can store, hold, or
transport your spray gun in a vertical position with no risk of falling over. Ready
to spray when you are! Disconnect the air hose from your spray gun and insert
the spray gun handle coupler into the Handi-Hold™ Spray Gun Docking
Stations (Figure A), as shown.
8. Maxi-Miser® 3000 PRO Operation
The Maxi-Miser® 3000 PRO turbo spray system is the newest HVLP technology patented by Apollo Sprayers International,
Inc. The 3000 PRO’s Precision Air Control Technology (PACT) accurately enables you to control the air pressure from the
turbo system to within 1/10th of a PSI. The 3000 PRO comes supplied with three 7600 PBC-GTO™ spray guns and a 37’ ultra-
flex™ air hose.
To operate the Maxi-Miser™ 3000 PRO it is important to connect the air hose and spray gun. The turbine will not operate
correctly without back pressure to the motor, which means the spray gun and air hose need to be connected. The 3000 PRO is
NOT compatible with “Bleeder” style spray guns (spray guns with continuous air flow from the air cap).
To operate your turbo spray system, connect the male end of your air hose to the turbo spray system. Next, connect the female
end to the spray gun handle coupler to the other end of your hose. Your air hose is now connected to the turbo system and
the spray gun. Next, plug the turbo spray system into single phase 240 volt electrical outlet. Next, push the power ON/OFF
switch to the ON position. The factory has calibrated your turbine motor for the maximum output pressure possible. To get an
accurate stable spraying pressure it is advised that you let the turbo system warm up for about 5-10 minutes prior to spraying
as you flow pressure will drop slightly as the turbo motors warm up. Once the turbine motor is warm the LCD will give you an
accurate pressure reading to 1/10th PSI with little or no fluctuation.
It is important to understand the difference between static or sealed pressure vs. flow pressure. When setting the air pressure
for spraying you should always set the flow pressure. You can set the flow pressure by connecting the spray gun and air hose
and turning the system on. Turn the material flow screw on the spray gun about 2 full turns counterclockwise (with the start
position all the way closed). Make sure you don’t have any material in the cup or, you don’t pull the trigger back all the way.
If you do, you will release the material in the cup. You only need to release the air pressure from the spray gun, not the
material in order to set the flow pressure. This is why it is preferable to set the pressure without any material in the cup.
Pull the trigger and release the air from the spray gun. While continuing to pull the trigger, adjust the pressure on the turbine
to the spraying pressure of your choice. Once you have set the pressure release the trigger. The pressure will stay where
you set it. Pull the trigger again and watch the LCD screen. You will notice the air pressure drop and then go back to where
you set the pressure. This will work for any pressure setting. NEVER set the air pressure at full power with the spray gun
closed. This will not give you any additional spraying pressure and will only overwork and possibly overheat your turbo system
motor when not being used.
The control board will automatically adjust the motor speed to compensate for barometric pressure and elevation. The pressure
reading in the LCD will always be accurate. To decrease the pressure from the maximum setting simply turn the knob
underneath the LCD pressure display counterclockwise, toward “MIN”. To increase the pressure once reduced, turn the knob
clockwise, toward “MAX”. As you turn the knob, the pressure will increase or decrease accordingly. The scale behind the knob
is there only to indicate the direction to increase and decrease the pressure. It does not represent any settings for the air
pressure, this is only to indicate the direction of increased or decreased air pressure.
The viscosity of the coating you want to spray will determine the amount of air pressure needed. The thicker your viscosity, the
more pressure you will need to atomize it properly. For highest efficiency, use the lowest pressure that produces the best
atomization and finish results. If you experience “Orange Peel”, increase the pressure. If you have too much overspray, decrease
the pressure.

Page | 16
The Maxi-Miser® 3000 PRO is equipped with an “Overheat” system. The Overheat system works to help prevent overheating
your motor. To prevent damage to the motor the turbine will shut itself down if it gets too hot. Overheating is usually caused by
clogged or dirty filters. The more the filters are restricted the hotter the motor will run. Once the overheating point has been
reached the turbine will shut off until the temperature inside the unit has cooled enough for the motor to once again operate
normally. When this happens an “OVERHEAT” message is displayed in the LCD screen. Do not ignore this warning. Clean or
change all your filters to prevent this from happening again.
The 3000 PRO, also equipped with an hour meter, which records the use of the turbo spray system in whole hours. To see
how many hours of use your turbine has, turn the power control knob counterclockwise until the indicator mark on the knob
lines up with the line for the Hour Meter. The LCD will then display the hours of use rather than the pressure.
9. Turbo Air Pressure and Viscosity
When using your Maxi-Miser® 3000 PRO it is important to understand the nature of the coating you are spraying and the
viscosity. Fairly thin materials like Basecoats can generally be sprayed with approximately 4-6 PSI. Medium bodied
materials such as sealers will require more air pressure, approximately 6-8 PSI. High Solids and heavy viscosity materials are
going to require 8 PSI or more to atomize them nicely. Always use the minimal amount of air pressure possible to achieve
the best results.

10. Turbine Maintenance and Cleaning
Always unplug your turbine from the main electrical supply before doing any maintenance or repairs.
After Each Use:
Your Apollo turbine system requires very little maintenance. The turbine motor has sealed bearings that are lubricated for life.
The only maintenance that you will need to perform is checking, cleaning and replacing your filters and pre-filters as required. It
is very important that your motor has cool, clean air to operate efficiently. If you maintain your filters and pre- filters well, you will
enjoy many years of long service from your turbine motor.
NOTICE
Always use genuine Apollo filters and pre-filters. Other types of filters and pre-filters may prevent proper air flow
to the motor, resulting in premature motor failure and voiding your warranty.

Page | 17
10.1 Pre-filter Maintenance
We recommend that you remove your pre-filters after each use. To remove the pre-filters: push your finger between the filter (1)
and pre-filter (2) until you can curl it up and pull the pre-filter off, rotating your finger around the pre-filter as you pull. Do not pull
hard as you will break the glue line on the pre-filter. Make sure you check all three pre-filters as they can get dirty at different
intervals. If they appear to be a little dirty or clogged, you can wash them out using a mild soap and warm water. If they are not
cleanable you need to install new pre-filters.
To reinstall the pre-filters, hold one in both hands and apply the top first, moving your fingers around the inside as you slide it back
over the filter cartridge from top to bottom. NEVER operate your turbine without both filters and pre-filters installed and clean.
10.2 Filter Maintenance
There are three filters on your Maxi-Miser® 3000 PRO. Visually check all your filters when you remove your pre-filters for
cleaning. Check for accumulated material in the filter element. If you suspect they may be dirty, or if you can see material
building up, don’t take a chance, remove the filters, and hold it up to the light.
To remove your filters, remove the two dome nuts (1) and pull filter plate (2) off. Filter plate can hang up on the threads so make
sure you pull it off straight.

Remove filter (3). If filter is stuck to the side of the case, gently tap the side with your hand.
To check your filters, hold them up to a light, similar to your car air intake filter. If you cannot see light through more than 50% of
the filter you need to wash it or replace the filter element.
NOTICE
Filter element may be damaged if more than 30 PSI of air pressure is used to blow out filter element.
If they appear to be dirty, you can tap them gently on a flat surface to remove any debris. If you have compressed air available,
you can also blow them off with air. If you use compressed air to clean your filters, make sure you blow the air from the inside
out and never use more than 30 PSI or this will damage the filter element. You can also use a filter cleaner and wash your
filters. Follow normal cleaning instructions of the bottle of cleaner you are using.
To reinstall the filters, reverse the instructions above. Make sure that the filters are dry if you washed them with water and you
line the filter up with the filter plate first. This will help to keep it straight when replacing the dome nuts.
10.3 Fan Filter Maintenance
In addition to the main motor filters there are also two additional fan filters that need to be cleaned and periodically replaced.
One of the fan filters is located underneath the house outlet (1) on the turbo unit itself and the other on the back of the control
panel (2).
