Filling the Throttle Preset

Your Throttle Preset air system can be filled either on or off the
gun. The Throttle Preset is supplied with an industry standard
quick disconnect fill nipple. The fill nipple is mounted on the
side of the Throttle Preset housing. Be sure to use compressed
air or nitrogen only. Be sure that the compressor and air system
supplying the air have the proper filters and moisture separators
installed and working. Virtually all regulator failures are due to
dirty, contaminated air. It is important to keep the fill nipple clear
of dirt and debris. Make sure to keep the fill nipple dust cover
on at all times unless in the process of filling.

Maintenance and Repair

DYE’s Throttle Preset was designed and built from the ground
up to provide the longest service life possible, with the least
amount of maintenance needed. All basic preventative
maintenance can be performed without removing the regulator
from the air bottle or disassembling the regulator housing.

1. Care should be taken to make sure that every time the
Throttle Preset is screwed into the gun’s ASA a small amount of
grease or oil is applied to the air system’s threads.

2. Be sure to keep the fill nipple cover on at all times when not
filling. This will help prevent any dirt or debris for entering the
regulator and damaging the regulator seat.

Additional Maintenance: The fill nipple o-ring and/or the
Schrader valve may need replacement after time and wear.

With performance and reliability in mind, the Throttle Preset air
system utilizes an advanced design that is hassle-free and
performs above the expectations of even the most demanding
player.

The Throttle Preset has a factory-set output pressure of
approximately 800 psi, eliminating the need for setup or player
adjustment. Simply screw the Throttle Preset into the gun’s ASA
(CA adapter) as you would a standard CO2 tank. Be sure to
apply a small amount of grease to the CA threads and bottle o­ring. The Throttle Preset utilizes a Schrader valve system for
output airflow control. When the air system is under pressure
but not in use, the Schrader valve shuts off the flow of air. When
the Throttle Preset is screwed into the gun, the ASA pin will
depress the Schrader valve pin and allow a free flow of air into
the gun.

To remove the Throttle Preset from your marker while there is
still air in the tank, simply unscrew the air system from the ASA.
As you unscrew the Throttle Preset the Schrader valve closes,
shutting off the airflow. The remaining air in the marker will vent
back out the ASA while you unscrew the Throttle Preset.

5. Be sure not to over-tighten the fitting, as this will cause
insufficient piston travel, which can result in o-ring failure.

The Throttle Preset also has a filter installed underneath the fill
nipple to help prevent any contaminants from gaining access
into the regulator system and damaging the reg seat or any
internal o-rings. While you have the fill nipple off, it is a good
idea to remove any debris that the filter has collected.

Housing Disassembly

If disassembly of the Throttle Preset becomes necessary, it
should be done by a certified DYE Throttle System repair center.
The DYE certified repair center will have the proper tools to
avoid damage to the external body of the regulator. The Throttle
Preset does not need to be disassembled unless the regulator
has failed in some way (e.g., supplying an improperly regulated
PSI). This will more than likely be due to contaminated air
damaging the seat or o-rings.

The Throttle Preset is built into a two-piece housing. The top
and bottom sections of the housing are threaded together using
left-hand threads (opposite of standard threads). For safety, the
top cap and main body are set together with a specialized glue.
As a secondary precaution there are two 6-32 set screws
locking the top cap in place onto the main body. There is no
reason to ever remove the Throttle Preset regulator from the
tank.

Schrader Pin Valve Replacement

If, for some reason, the Schrader pin valve begins to leak and is
no longer able to retain the air in the Throttle Preset, the
Schrader valve can be quickly replaced.

1. Use a standard car tire valve tool to remove the old Schrader.

2. Install the new Schrader. Be careful not to over-tighten the
new Schrader valve as it might break under excessive force.

Servicing the Fill Nipple

1. To replace the fill nipple o-ring simply use a 7/16 wrench and
unscrew the fitting from the regulator housing.

2. Once you have removed the fill nipple from the housing you
will need to knock the piston out of the fill nipple.

3. The o-ring is on the piston. Remove the old o-ring and
replace it with a new UR90 #006 o-ring.

4. Once you have the new o-ring in place and the nipple and
piston reassembled, apply thread sealant to the male threads of
the fill nipple and thread it back into the regulator housing.

8. Make sure the cap threads are clean before screwing
the cap tightly back onto the main body. Lock the
setscrews down to make sure the cap does not come
loose during use.

To access all internal parts including the reg seat the top cap
must be removed from the main body. Consult the exploded
drawing below for reference.

1. Remove the two 6-32 set screws from the side of the top cap.
Failure to do this could result in permanently damaging the main
body threads.

2. Unscrew the top cap from the main body using one of DYE’s
special assembly collets. If you don’t have one, use a set of soft
jaws in a vise.

3. Once the top cap has been removed, the Belleville springs
and piston can be removed.

4. Replace both o-rings UR90 #006 and UR90 #012.

5. Replace the reg seat, which can be pushed out from the top
of the piston. Be sure that the new

seat is fully inserted into
the bottom of the piston. Also make sure not to damage
the sealing surface of the new seat when pressing it into
the piston.

6. To reassemble, arrange the Belleville discs in the
proper order (see diagram) and drop into the main body
of the Throttle Preset.

7. Grease both o-rings on the piston. Push the piston
down into the main body through the Belleville springs.
