Whats new that you need to understand
about the L7 bolt.....
The big thing to understand is that the LPR (Low Pressure Regulator) only controls
the amount of pressure pushing the bolt backwards
in the breech. Not forward like the stock bolt. If at anytime
your bolt is hanging forward into the breech when the gun is at
rest, turn LPR up until the bolt moves back into the proper position.
Dwell
The easiest
way to set up your new bolt is by starting your dwell at 18...or
at whatever your old bolt was running at. We are going to start
the dwell high and then adjust it down as we go.
1.
So
step one is to set your dwell to 18. If you are not sure how to
set your dwell consult your owners manual. Most are available
online if you don't have your's anymore. If you are using an after
market board use the same dwell you have been using with your
old bolt.
2.
Also, be sure to turn your ABS
(Anti Bolt Stick) OFF.
Consult the markers owner manual if you
are not sure how to turn it off. This is pretty crucial.
3.
Now
turn your Low Pressure Regulator
(LP Reg or LPR)
all the way down. You do this by turning the LP Reg all the way
CLOCKWISE (IN). Now, turn it back out (COUNTER
CLOCKWISE) by 6 turns. This should be enough
to get the bolt to stay back in most guns.
*** On some markers the Low Pressure Regulator is in the rear
below the bolt.
Lower
the pressure coming from your HIGH
PRESSURE Regulator (HP
Reg) down to zero. If you are using the stock Dye reg,
you down this by turning the screw at the bottom of the reg CLOCKWISE
(IN) as far as you can. Other regs adjust differently,
so make sure you know what way you are going.
If you are
not sure, you could remove the reg from the gun while leaving
it connected to the ASA, and gently apply air to the reg. Holding
it tightly, adjust the reg until no air is coming from the reg.
This can help let you figure out which way to turn in order to
go down in pressure.
At this point
just understand that we are going to start with a high dwell and
then work lower. As we lower our dwell we will gain air efficiency,
but once too low ....we'll loose consistency. We are trying to
find that perfect balance between the two attributes, and it take
alittle time and patience.

READ and UNDERSTAND ALL OF THIS
BEFORE YOU AIR UP THE MARKER.
With
NO PAINT ON THE GUN - Turn the marker on,
the eyes off, and air up the marker
in that order.
With the marker
in one hand and an allen key in the other, slowly turn up the
pressure from your main HP Reg by turning it COUNTERCLOCKWISE
on the Dye Hyper Regs. (Different regs adjust differently)
So
thats, dry fire the marker at the same time you are SLOWLY turning
up the HP reg.
As you gradually
increase the pressure coming from the HP Reg,
the marker will start to shoot or the bolt will
just stay forward and spew air out the face of the bolt. If
the bolt is spewing air, you need to give the LP Reg
another full turn out or as many as it takes to get the bolt to
stop leaking down the face of the bolt.(counterclockwise turn
increase the LPR).
The bolt will
only leak if the bolt does not having enough pressure pushing
the bolt backwards. With our bolt the LPR only controls how much
pressure pushes the bolt backwards. With the stock bolt players
need to be concerned with how high their LPR is set to. This is
because the LPR controls how much pressure moves the bolt forward.
The more pressure, the harder it is on paint. This is not true
with our bolt. The input pressure is the only thing pushing the
bolt forward. This is also why you will notice that our bolt takes
smaller reg adjustments to fine tune the velocity. If
when you air the marker up the bolt is not leaking,
good. Look into the breech and see is the bolt is all the
way back in the breech. If after you pull the trigger the bolt
hangs into the breech...up the LPR gradually and continue to pull
the trigger as you increase the LPR. Stop increasing the LPR once
the bolt fully retracts after each trigger pull.
Now go chrono
the marker at the field, and hand feed paint to get the marker
to shoot 300 fps or whatever you shoot at your field. You may
find that you may need to increase or decrease the HP reg to get
the desired FPS. As you make adjustments to the HP reg for the
desired FPS, check the status of the bolt tip with each adjustment.
Make further increases to the LP Reg as needed to keep the bolt
tip back.
IMPORTANT
Once you get
it shooting 300fps and the marker looks and feels like its performing
well, put a hopper on the marker and test fire a stream of paint.
If all is good.....go play a game with this setup.
If
the consistency is good during the game (accuracy), after the
game, lower their dwell by one flash. Then
go play another game.... see
if the change in dwell noticeably negatively affected the consistency
(accuracy). If
not, lower
the dwell again by 1 after that game.
Continue to lower and test until you notice a loss
of consistency at low and high rates of fire. Once you notice
a decrease in consistency, you need to increase your dwell back
up to regain the consistency. I would go up one
to two flashes in dwell just to be
safe.
If
for some chance you get the drop off at high rates of fire, try
increasing your dwell by 1 after each gome until it goes away.
Keep in mind if the problem wont go away easily you may have a
dead or dieing battery and you may need to lube and clean your
bolt. I'd go in adjustments of 1 with the dwell until high firing
rate drop off us gone.
NOTE:
I
have found that PM markers typically perfer a dwell between 3-10
flashes, and DMs need alittle higher....between 12-15 flashes.
I know it sucks a little for DM owners....it seems that they may
have used a slower solenoid on the DMs....which I think is odd
seeing as they DMs cost more than the PMs.
All the guns and boards are little different, so no two set-ups
are going to be exactly the same. The best setup is just a balance
between your dwell, LP Reg, and HP Reg.
| We have had some trouble getting all the DM
solenoids to operate at what the bolt naturally wants to operate
at with no spacers...90 psi. That’s right, with the DM5,6,7,8
or bolt shoots 300 FPS at 90psi. We have found that it too low
for a few of the DMs solenoids to operate at. At this pressure
they would half cycle. So we have introduced spacers to get the
pressure all the way up to 125ish. If you have picked up one of our bolts and you are trying to install it on a DM4,5,6,7, or 8, you may need/want to pick up one of our Top Hat Mod Spacer Kits. This kit will help DM's shoot more consitant at the lower pressures. |

Common problem
I see : Problem : Bolt fires every other shot.
Fix = Turn up your LPR until the bolt stays back after each shot. This can also be a sign that you need a spacer kit, or perhaps even up your dwell by 1 or 2. If none of this helps, let me know. Email me at: todd@techtpaintball
If you can please watch the install video above, its very helpful and makes short work of some long instructions.
Thanks for your support,
