Shoots more 
than once from 
one trigger pull
Battery may be low. Replace battery with a fresh name brand alkaline 9-volt.
Trigger may need to be adjusted. Make sure the trigger has plenty of travel both before and after the 
activation point.
Regulator leaks 
from bottom plug
Adjust over-pressurization relief valve. The plug on the underside of the regulator is an over-pressurization relief. 
If it is leaking, most likely the regulator is set to too high of a pressure and 
needs to be lowered. If the regulator is set to 200 psi or less and the over-
pressurization relief is still leaking, it is possible to turn the plug cap just a 
small amount in the clockwise direction, until the leak stops.
Regulator is slow 
to recharge
Air tank is not screwed all the way 
into the Mini’s regulator ASA.
If during rapid firing the first ball comes out of the barrel at full velocity and 
following shots decrease substantially, watch the gauge on the Mini regulator 
to see if the needle drops down significantly and is slow to come back to the 
set pressure. This is typically the result of not screwing your air tank in enough. 
When screwing your air tank into the Mini’s regulator ASA, it is important to 
not stop as soon as the marker pressurizes, but to continue turning until the 
air tank stops. It is also acceptable to install the air tank when it is empty, then 
have it filled by a professional while it is installed. This will ensure that you get 
the maximum air flow from your air tank.
Regulator 
pressure spikes
Regulator adjusted too high. If the needle on the regulator’s gauge climbs well over 200 psi when attempt-
ing to install the air tank, first remove the brass adjustment screw in the front 
of the regulator and try again to install the air tank. If the needle reads 0, 
reinstall the adjustment screw and turn in until the needle reads 200 psi.
Breaks paint 
in chamber
Eyes are turned off. Only fire paintballs with the eyes on.
Low quality or brittle paintballs. Do a paintball drop test. On a level and smooth, hard, outdoor surface, such 
as concrete or asphalt pavement, drop ten paintballs one at a time from about 
5 feet high. Don’t toss them up or throw them at the ground, just drop them 
straight down. If more than 3 paintballs out of 10 break, the paintballs are bad 
and should not be used in the Mini. In the case of higher-end tournament-
grade paintballs, it may be possible to tune the Mini to successfully fire brittle 
paintballs. Since all conditions are different, it is best to ask for help with this 
from your local pro shop.
