2. Maxi-Miser™ Spray Finishing Systems

CONGRATULATIONS!! You have just purchased the Maxi-Miser 2000 HVLP turbo
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 40 years of experience in manufacturing HVLP turbo spray systems and spray
guns. We have painstakingly 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 spraying; 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™ 2000 Turbo Unit (1) Spray Gun Lube
(1) PBC-GTO™ Clear Coat Spray Gun (1) Blow-off Tool
(1) PBC-GTO™ Base Coat Spray Gun (1) Cleaning Brush 
(1) 37’ Flex-Air Hose (1) Electric Cord 
(1) Instruction Manual (1) Wrench
(3) Quick Couplers (2x Handi-Hold™) (1x Hose Coupler) 

3. How Your Maxi-Miser™ Turbo System Works

Your Maxi-Miser™ system has three components: the turbo unit (1), spray gun (2) and air hose (3). The turbo unit,
when connected to the correct electrical 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 turbo 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.






~6~

4. How Your PBC-GTO Spray Gun Works

Your Apollo Maxi-Miser™ PBC-GTO™ Spray gun operates similar to 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 tip/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.
When the material adjustment screw is opened and the trigger pulled back, fluid flows through the tip/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 in 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 turbo 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 an outlet that is properly installed and grounded in accordance with local codes and ordinances
and the proper voltage. Your Maxi-Miser™ system is rated for either 120 volts or 240 volts. Please check the Serial
number plate located underneath of the system to check which voltage your system is designed for. The Turbo system
does not work on dual voltage. Plugging the turbo system into the wrong voltage will damage the motor and void your
warranty.

NOTICE 
Do not cover or enclose the turbo. It is important to draw cool/ambient air through the unit for
optimum performance. Avoid placing the turbo in a warm environment or in direct sunlight.

6. Setting up Your PBC-GTO Spray Gun
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 gun comes with a 600cc Gravity Feed cup assembly. 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.


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.
2. Remove the screw in the side of the spray gun body using the
wrench (spanner) provided.





3. Screw the air feed connector onto the side of the spray gun body.



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
full, open, wide pattern. (Relative to the distance the spray gun is held from the
work surface).

~9~

To adjust the direction of the fan pattern, loosen the air cap ring, (Fig. 1) rotate the air cap ears (Fig. 2) 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).
Filter and pour into spray gun cup. 

Connect the appropriate air hose to the spray gun. Begin turning the material adjustment screw (#19) anti or counter
clockwise 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/counter clockwise. Hold spray gun 4” – 8” (10cm-20cm) 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.
6.2 Spray Gun Technique
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. 

~11~

4. At the end of a “pass” always release the trigger. To continue, spray in the opposite direction and overlap your previous
coat by 1/3 to 1/2. 
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 slowly. 
6. When spraying a large piece, start at the top and work down. 
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”-8” (10-20cm) is ideal. Closer if necessary. 
3. Pattern direction (vertical fan, horizontal fan 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 have finished spraying, follow these simple steps to clean your PBC-GTO spray gun:
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 clear coatings, a
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. Cleantheairdistributorandtheaircapringthoroughly.

~12~

4. Using a brush and solvent, remove any paint deposits on the outer surface of the tip/nozzle (#3). (Apollo FS1900
cleaning brush kit recommended).
5. Unscrew and remove the material adjustment screw (#19).
6. Remove the needle spring (#20).
7. Pull the trigger and then pull the needle (#21) out through the back of the spray gun.
8. Remove the fluid nozzle (#3) with the wrench (spanner) provided.
9. Clean both fluid nozzle and needle assembly using cleaner or water and a brush.
10. 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.
11. To adjust the Gland nut (#23) tighten until the needle sticks, then back off the nut about 1/8 turn. Do not over tighten
the gland nut or the needle will stick. Do not under tighten or the Gland Seal will leak.
12. Check the Cup Top Gasket and replace 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.
NOTICE: Make sure to leave the Air Cap Ring (#1) lose until you use the spray gun the next time. This will prevent
the Air Cap Ring (#1) from gluing itself to the Air Distributor (#6) causing damage to your spray gun.
6.3.2 Thorough Cleaning
Follow steps above for partial 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.



4. Remove the fan adjustment ring (#8) and air distributor plate (#7). The air distributor plate is attached to the ring.
These two pieces 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).
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. 


~14~




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 show in the picture marked “incorrect”.

1. Place the Air Distributor (#6) on top of the paired fan adjustment ring and Air
Distributor plate.

2. Align the screw hole in the Air Distributor (#6) with the holes in the fan adjustment ring and air distributor plate. 


3. Holding the head of the spray gun facing you,
place the Air Distributor Assembly onto the body of
the spray gun aligning the round holewith the locating
pin in the spray gun body at the 5 o’clock position. 

4. 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 the wrench (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.





5. 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).

6. Push the needle (#21) back into the spray gun.

~15~


7. Insert the Needle spring into the Material Adjustment Screw (#19). 
8. Install the Material Adjustment Screw with Needle Spring (#20). 
9. Install air cap and air cap ring. Spray gun is now re-assembled and ready to use.

Periodically, use Apollo lubricant to lubricate the air valve bushing as shown.










Pressure will remain in the spray cup when 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 System

Handi-Hold™ Spray Gun Docking Station 

Your Maxi-Miser™ turbo system comes equipped with two Handi-Hold™
Spray Gun Docking Stations (A). Store, hold or transport your spray gun in a
vertical position with no risk of it falling over. Ready to spray when you are.
Disconnect the air hose from spray gun and insert spray gun handle coupler
into the Handi-Hold™ Spray Gun Docking Station (A), as shown. 
  
8. Maxi-Miser™ 2000 Operation

The Maxi-Miser™ 2000 turbo spray finishing system is the newest creation by
Apollo Sprayers International, Inc. The Maxi-Miser™ 2000’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 Maxi-Miser™ 2000 comes supplied with
two PBC-GTO™ spray guns and a 37’ air hose. 

In order to operate the TurboPrp™ 2000 it is important to connect the air hose and spray gun. The turbo will not operate
correctly without back pressure to the motor, which means the spray gun and air hose need to be connected. The Maxi-Miser™
2000 is NOT compatible with “Bleeder” style spray guns.
To operate your Maxi-Miser™ 2000 connect the male end of your air hose to the turbo system. Next, connect the female end to
the spray gun handle coupler. Your air hose is now connected to the turbo system and the spray gun. Next,plug the turbo
system into the appropriate electrical outlet. Next, push the ON/OFF switch to the ON position. The factory has calibrated
your turbo 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. Once the turbo 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 counter clockwise. Make sure you don’t have any material in the cup or that 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 turbo 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 possible overheat your turbo
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 pressuredisplay counter-clockwise, 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 on behind the knob is there only to indicate the direction to increase and decrease the pressure. The scale behind
the knob 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. 

The Maxi-Miser™ 2000 is equipped with an “Overheat” system. The Overheat system works to help prevent overheating
your motor. To prevent damage to the motor the turbo 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 overheat point
has been reached the turbo 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 your filters to prevent this from happening again.
The Maxi-Miser™ 2000 also is equipped with an hour meter, which records the use of the turbo in whole hours. To see
how many hours of use your turbo has, turn the power control knob counter-clockwise 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. 
NOTE:
*All turbo pressures quoted are measured sealed and at the motor outlet. Actual spraying pressures will vary when the
spray gun and hose are connected.

9. Turbo Air Pressure and Viscosity 
When using your Maxi-Miser™ 2000 it is important to understand the nature of the coating you are spraying and the
viscosity. Fairly thin materials like Base coats can generally be sprayed with approximately 2-4 PSI. Medium bodied
materials such as sealers will require a little more air pressure, approximately 4-6 PSI. High Solids and heavy viscosity
materials are going to require 6 PSI or more to atomize them nicely. Always use the minimal amount of air pressure
possible to achieve the best results. 

10. Using Pressure Pots with Turbo Systems
There are many advantages to using pressure pots with a turbo system. Apollo Sprayers have made this very easy with
our fluid feed systems, 4500 and 4550. Refer to the accessories section of this manual for more information on these and
other products. By removing the paint cup from the spray gun you immediately reduce the overall weight of the spray gun
by ½. You also get a smaller tool to hold in your hand thereby allowing you to more easily
access tight spaces where a standard cup gun would not fit. By using a pressure pot you
are able to spray larger quantities of material without stopping to refill a smaller cup. This
can save a lot of time on a long job where you are spraying the same material on a bus or
truck.

Using a pressure pot with a turbo system is very easy. All you need is any size pressure
pot, a fluid hose and a small air brush aircompressor. When using a remote cup or pressure
pot, it is necessary to introduce compressed air in order to pressurize the remote pot and
move the fluid from the pot to the spray gun nozzle. In general 5 PSI (0.345 Bar) of air
pressure is adequate to push most average viscosity fluids to the spray gun nozzle. Higher
pressure would only be necessary for heavier viscosity fluids or if you are spraying up a
ladder where the fluid has to travel more than 6 feet of elevation.

Connect the black fluid hose to the fluid outlet on the top of the pressure pot. Refer to your pressure pot instructions for the
specific location of the fluid outlet. Seal the threads with Teflon tape and tighten with a wrench (spanner) to assure no fluid
leaks once you pressurize the pot. Next, connect the air line from your compressor to the air inlet. This should be a male
quick connect adjacent to the regulator and gauge. If your quick connect is the same style as the one on the pot you can
pull back the ring on the female end and insert into the male end, releasing the ring to fasten them together. Connect the
other ends of the fluid line and air line to the spray gun and air compressor respectively. Your turbo air hose will connect
as normal directly to your spray gun.
