barb of the ram. The 3-way plays a major roll in
the proper function of the gun.
YOU’LL NEED:
5/16" open end or needle nose pliers
ADJUSTMENT STEPS:
1. Set the marker in normal operational mode
for firing.
2. Hold the marker in your left hand and focus
on the 3-way. Locate the brass shaft. It is
located in the front of the 3-way and can be
seen through the external vent port. On the
backside of the 3-way you will find the actua-
tor collar, it is hexagonal in shape and has
two sets of holes tapped into the body. The
set in the front is used to lock the 3-way
shaft in with the collar (keep in mind only
one set screw is used, the other port is left
open.) The set in the rear houses the shaved
nylon screws preventing the actuator rod
from rotating out of adjustment.
3. Checking the shaft position. Still holding the
marker in your left hand, place your thumb
on the bend radius of the actuator rod
(directly above the trigger) and push it for-
ward. Note: On the GX-3 the trigger will be
resting in a forward position when this step
is in progress. However on the GX-4 the trig-
ger will need to be depressed. This is due to
the reverse characteristics of the swing
frame. Look inside the front vent port of the
3-Way. Using your thumb, press the bent
radius forward and notice the brass shaft
move as pressure is applied. There is a slight
gap between the trigger plate and the actua-
tor rod. This is the gap we are eliminating by
pushing the rod forward. Your goal is to have
the brass shaft sit flush with the 3-Way body
as the actuator rod is fully extended.
Achieving this will give your marker its best
performance. If the shaft does not sit in a
proper position, it will either create a leak or
slow down the action of the marker.
4. Adjusting the shaft position. Use a 5/16"
open end or needle nose pliers to rotate the
hex collar on the actuator rod so that the
shaft tip and the 3-way body are on the same
plane when the actuator rod is fully extend-
ed. Note: Turning the hex collar counter-
clockwise will lengthen the position of the
shaft. Turning it clockwise will shorten it up.
3-Way Shaft adjustment is now complete.
Sear Lug Timing Check
The sear lug is the only internal component
of the GX-3 or GX-4 that may require adjustment
over a period of use. It is part of the hammer
assembly and can be accessed through the timing
hole located right behind the feed neck. The lugs
position has a direct result on the firing sequence
of the marker. Note: keep in mind that all the
markers come timed and tuned to their optimum
performance before they are shipped. Only after
usage will you need to adjust the depth of the lug.
Before any adjustments are made to the sear
lug you will first need to perform a simple timing
test. This will determine if the timing on your
marker is delayed, advanced, or at optimum
performance.
YOU’LL NEED:
No tools
CHECKING STEPS
1. Gas up the marker and fire it a few times.
2. Hold the marker in your right hand.
3. Pull back the trigger very slowly and pay
attention to the release time of the lug of the
sear plate.
Marker timing is at OPTIMUM PERFOR-
MANCE only if the full cycle of the trigger pull
is broken down in this order: As you start
pulling back on the trigger, you notice that the
contact between the lug and the sear is positive.
About half way into the pull, right before the
3-way actuates and forces the back block to
move, the marker fires. After the marker has
fired the back block needs to have full pressure
going back. Note: keep in mind that the block
needs to be resting against the body when the
hammer strikes the valve pin.

3. Loosen (counterclockwise) the Quick Twist
knob about 2 turns.
4. Open the gas valve to pressure up the
marker. Nothing should happen because
there is no tension on the Belleview washers
inside the regulator.
5. Tighten (clockwise) the Quick Twist knob.
This will compress the washers and allow
pressure to flow into the marker. The micro-
gauge will begin to register a pressure read-
ing and the regulator will tighten against the
body of the marker. Continue to tighten the
Quick Twist knob as necessary to set the
regulator to the recommended marker pres-
sure. Most markers will achieve maximum
performance between 225-275 PSI.
6. Fire the marker and recheck the pressure
setting.
7. When the recommended operating pressure
is set, tighten (clockwise) the 2 set screws
(or the lock washer for newer models) on the
bottom of the Quick Twist adjuster to lock
it down.
X-2 Inline Regulator adjustment is now
complete.
YOU’LL NEED:
No tools
ADJUSTMENT STEPS:
1. Set the marker in normal operational mode
for firing.
2. Loosen (counterclockwise) the Jack Hammer
knob, which is located to the front of the
regulator. Shoot the marker to relieve the
backpressure. You will notice that the back
block will no longer move when the trigger
is activated.
3. Push the back block forward towards the
body.
4. Hold the trigger back and tighten (clockwise)
the Jack Hammer knob slowly. As the pres-
sure is increases and air cycles through the
ram, the back block will start to move back.
5. When the stainless steel pump arm rod is
fully extended or there is no longer any
slack left on the back block, rotate (clock-
wise) the Jack Hammer knob another 1/4
turn and stop.
6. Release the trigger and shoot the marker.

Timing Adjustments (GX-3 and GX-4)
On a new marker, optimum timing is preset
from the factory and should not be adjusted.
Following extended marker usage, periodic
timing adjustments should be made to assure
continued optimum performance. Timing the
GX-3 and GX-4 is a simple adjustment of two
major components:
The 3-Way Shaft
The Sear Lug
To achieve accurate timing results, adjust
the 3-Way Shaft before attempting any adjust-
ment to the Sear Lug.
3-Way Shaft Adjustment.
The 3-way is a small cylindrical piece, which
sits at the front of the maker underneath the
barrel. Extending from the top of the 3-Way are
three barb fittings-two lead to the ram and one
leads to the Jack Hammer. On all new markers,
this part is preset from the factory and should
not be adjusted at first. As the marker is used, it
may be necessary to check over from time to
time. The function of the 3-way is to allow regu-
lated air to pass through to the front and rear

It regulates the pressure needed to operate the
front pneumatics. NOTE: This part is preset
from the factory and should not be adjusted on a
new marker. Adjustment will be necessary only
if the user has altered factory settings.
