Vanquish GT: Shooting Issue

Marker will not fire or has a problem firing. Check the items below. Reference the manual if needed.

Issue:
Aired Up with No Leaks & Won't Fire:
  • Before starting, be sure you're using a new battery and an air tank that's supplying enough air pressure (500-650psi). Your marker should also not have any leaks. Next, perform the following general checks:

    • Battery: Even if your battery is new, unplug it for 2 seconds and reconnect it, then retest

    • PC Connection: Be sure to disconnect your marker from your PC as having it connected may prevent it from turning on

    • Circuit Board: Check that the front grip frame screw is fully tightened, which will allow for the best possible connection between the main circuit board and the front circuit board

    • Eyes

      • Ensure the eyes are turned on and functioning. If not, press the D-Pad in the Up direction to change the setting

      • When a paintball is in the chamber/breech, it will be indicated on the marker's display by a solid circle as shown in the screenshot below. From left to right, the display images indicate  Eyes Off, Eyes on no ball in breach, Eyes on - Ball detected in breach, and Eye malfunction

  • Config Menu:

    • Navigate to the current profile being used and then to the config menu for that profile

    • Ensure your eyes are turned on and that the marker is not in Training Mode as this will prevent the marker for firing. Instead, you'll hear a chirp when fired

  • Air Pressure

    • Check your air pressure via the display and confirm it's shown as under 200psi and is not showing as "Low." Use a 3/32 hex wrench to Modify the adjustment screw as needed (Clockwise/Inward = Increase pressure, counter-clockwise/outward = decrease)

  • Dwell

    • Check your dwell & reset it to the factory default setting of 12m

Marker Won't Turn On:
  • Battery:

    • Start with a new battery, as an old one will cause issues

    • Even if your battery is new, unplug it for 2 seconds and reconnect it, then retest

  • PC Connection:

    • Be sure to disconnect your marker from your PC as having it connected may prevent it from turning on

  • Circuit Board

    • Check that the front grip frame screw is fully tightened, which will allow for the best possible connection between the main circuit board and the front circuit board

Marker is Not Air Efficient:
  • If you're not getting the expected number of shots per fill from your air tank and you don't have any leaks, check the following in the order shown below.

  • Paint to Barrel Match:

    • Make sure you're using good quality paintballs and that you have a good paint to barrel match. Freak barrel inserts can help improve this match-up.

  • Dwell

    • Check your dwell & reset it to the factory default setting of 12ms

  • Firing Engine:

    • Remove the firing engine, disassemble and wipe it down

    • Next, check the bolt tip for any damage and replace if needed

    • Clean and lubricate the firing engine. Reference the maintenance section for details on O-ring sizes. Inspect the following O-rings specifically for damage and replace as needed. Lube with Dow33

      • Outside of Air guide - 2nd from the front

        • 020 x4 (Urethane 70) - #26 V16 Air Guide (#2 on pg 26)

      • Inside of the Air Guide, 2nd from the front

        • 017 x3 (Urethane 70) - #29 V16 Air Guide (#3 on pg 26)

Marker Fires with Low First Shot:
  • Battery:

    • Start with a new battery as this can cause issues

  • Dwell

    • Check your dwell and try resetting back to the factory default setting of 12ms.

  • Pressures

    • Verify that the gauge on your ASA/regulator shows 200psi. Adjust if necessary

  • Firing Engine:

    • Clean and lubricate the firing engine. Reference the maintenance section for details on o-ring sizes if any need to be replaced

  • Anti-Bolt Stick (ABS) Wait Time:

    • Check that the default of 30s if set. Try increasing this value after servicing your firing engine if the issue remains

Multiple Balls Fired on Single Shot:
  • Detents

    • Check and clean your detents with a cloth to prevent paintballs from catching on them. A small amount of lube can also be added to allow for easier passage.

Marker Fires Slowly:
  • Firing Engine

    • Clean and lubricate the firing engine. Reference the maintenance section (or the video below) for details on performing this maintenance. O-ring sizes can be found on the maintenance page

  • Rate of Fire

    • Try increasing your marker's rate of fire (Default is 8bps)

  • Loader too Slow

    • A loader in need of new batteries or one that doesn't feed fast enough to keep up with your current rate of fire setting, can cause this issue
