FAQ- MARQ Gen2 Technician Tips
This section has information and technician tips relating to the Field One Gen2 MARQ (VIS and VCOM Engines). If you have a question or need advice on a technical issue, please email us: firstname.lastname@example.org
As always, whenever you are handling your paintball marker, be sure you are handling in a safe manner and following all paintball safety guidelines and local rules/ regulations.
Be sure you are in a safe area to shoot your marker. Be sure you and the people within range are wearing approved paintball eye protection.
Marq Victory (Gen2)
Where can I find the owners manual/technical manual for this paintball marker?
The owner’s manual for this marker is available online on the Field One Paintball Website or by clicking HERE.
How often should I perform maintenance on my Marq?
Before you play- Pressure Test and Chrono your marker
Start of Weekend- Clean/lube engine(VCOM Engine), clean barrel and breech area, check/change battery
Once Month/ Before Event- Clean / relube regs, inspect eyes and detents
Once a year/ Season- Rebuild MARQ Engine and regulators
What tools do I need to do standard maintenance on my Marq?
Standard Allen Wrench Set, Small Phillips Head Screwdriver, Marq Gen2 Pressure Tester(Available from Field One), Lube (Dow 33 or Field One Lube), Needle Nose Pliers or Schrader Valve Tool, Barrel Cleaning Squeegee
What is the recommended operating pressure and dwell for the Gen2 Marq?
These are the recommended starting operating pressures for your Gen2 MARQ. Set your marker using a pressure tester and then make small adjustments as needed to reach your desired velocity.
VIS Engine- HPR~180, LPR~80, Dwell~8
VCOM Engine- HPR~180, LPR~80, Dwell~10
Super Charged Engine- HPR~210, LPR~85, Dwell~6
Proficiency Engine- HPR~220, LPR~85, Dwell~6
(Hint: the MARQ solenoid has an LPR operating range between 30psi and 100psi- operating the solenoid outside of this range can cause a leak or damage to the solenoid)
The ideal output pressure for your tank regulator is between 300psi and 500psi (depending on fire rate). The Gen2 MARQ, in most cases will perform with higher tank output pressures but this will increase the wear on regulators/o-rings and seals and may yield lower efficiency.
Why is my Marq experiencing low velocity?
At the F1 Factory Service Center, we have found that most issues that present with low or inconsistent velocity or a leak can be remedied with an engine and regulator rebuild. If you don't have the time or the proper o-rings/seals to perform a complete rebuild, here is a checklist of simple procedures that can fix a low velocity issue.
- Check pressures and set to the applicable factory settings for your engine (listed above)
- Check your dwell setting and set to the factory recommended setting
- replace the battery
- replace the 1x14mm o-ring between the back block and ram housing
- replace the 006 o-rings on the bottom(outside) of the engine to help with LPR consistency
- VCOM engine- replace the Ram o-ring (011), replace the brass shutoff o-rings(110 and 012)
- increase LPR setting slightly (~5 psi)
My Marq is leaking……
At the F1 Factory Service Center, we have found that most issues that present with low or inconsistent velocity or a leak can be remedied with an engine and regulator rebuild. If you don't have the time or the proper o-rings/seals to perform a complete rebuild, here is a checklist of simple procedures that can fix a leak issue.
- VIS engine- replace the 021 o-rings on the outside of the volume chamber, replace the 014 o-ring inside the volume chamber, replace/clean the donut or blast guide.
- VCOM engine- replace the 021 o-rings on the outside of the volume chamber, replace the U-Cup inside the volume chamber, inspect the stem of the bolt tip for scratches or pitting.
- VIS engine- replace 006 o-rings on the outside of engine, replace the 020 o-ring between the 2 engine halves.
- VCOM engine- replace 006 o-rings on the outside of engine, replace the 1x25mm or 018 o-rings on either side of the brass shut-off.
Upper Grip Frame Area
- Solenoid may be leaking due to LPR presuure too low or high(spiking) or the solenoid may be dirty or have fouled internals. (Hint: the MARQ solenoid has an LPR operating range between 30psi and 100psi- operating the solenoid outside of this range can cause a leak or damage to the solenoid)
- 1x3mm o-ring between solenoid and manifold or body may need to be replaced.
- 1x4mm o-ring between body and grip frame may need to be replaced.
- 1x6.5mm o-ring between LPR and body may need to be replaced.
- LPR hose or barb may be loose.
- VCOM- ram and shut-off o-rings may need to be lubed or replaced.
Lower Grip Frame Area
- 1x4.5mm o-ring between ASA and grip frame may need to be replaced
- 1x4mm or 005 o-ring in ASA Main Seal/Support may need to be replaced if leaking from knob area
- grip frame may be bent if the marker was dropped or took a hard dive(heavy force exerted on ASA/Grip frame mounting screws)
Why is my Marq inconsistent at the Chronograph?
Inconsistency at the chronograph can be caused by a few different issues. Some common factors that are independent of the operation of the marker that you may want to consider are:
1) Overall quality of paintballs
2) Paintball size to barrel bore sizing
These issues are discussed in the F1 General FAQ section- you can get there by clicking the link here: F1 General FAQ
For consistency issues that are related to the operation of the marker, we will start with the most common(and easiest to fix) and move on to some of the more complicated matters. With good quality paint and a well maintained and tuned marker, you can expect to get a string of shots that are all within 10fps of one another. Most paintball fields have safety guidelines that require players to shoot between 260fps and 300fps maximum.
At the F1 Factory Service Center, we have found that most issues that present with low or inconsistent velocity or a leak can be remedied with an engine and regulator rebuild. If you don't have the time or the proper o-rings/seals to perform a complete rebuild, here is a checklist of simple fixes that can fix a velocity inconsistency issue.
- Pressure test and set to factory recommended specs(listed above by engine type), slowly raise LPR setting as you chronograph(with clearing shots between adjustments) until you reach consistency. DO NOT exceed 15psi above factory specs (listed in above section by engine type). Be sure your HPR setting does not drop below factory spec as you raise the LPR. The LPR/HPR system requires balancing to function properly, adjusting one regulator will have the opposite affect on the other regulator setting. USE A PRESSURE TESTER to start your adjustments.
- Clean and lube your HPR, replace the 016 o-ring on the HPR piston. If your pressure tester is showing any spiking or slow creep from your HPR or LPR, you will need to replace the respective Schrader valve. The regulator piston inside the HPR and LPR should be clean, have an adequate amount of F1 approved lube and slide smoothly within the regulator housing.
- VIS engine- Blast guide may be worn badly, causing the blast guide(poppet) spring to catch as the blast guide moves- replace blast guide and spring.
- Solenoid may be fouled or not outputting adequate power- replace solenoid.
