REPAIR MANUAL
HAND GUN
For simple repair or replacement of O-rings on front plunger, please have ready the following tools:
Plumbers thread seal tape or silicone sealer
Lubricating oil, any household oil or motor oil
The allen keys provided with your kit
The new o-rings provided in your kit
A used Co2 cylinder or a wooden dowel
An old towel to use as a cover on your work table
STEP ONE
As seen in this photograph,
remove the knurled screw-in plug that secures the Co2 cylinder
remove the empty Co2 cylinder, but keep it handy for later use
you will see an allen screw just in front of the handle, (this secures the plunger) remove it and clean it
now, using the smaller allen key, push the plunger out of the chamber through the little hole
the plunger is attached to a spring and washer as per the next photograph
STEP TWO
Remove the 2 o-rings and replace with 2 new clear or white o-rings, you may have
needed to
separate the spring from the plunger to do this.
Whilst you are at this point it will pay you to clean the air chamber by using a
little oil applied to a
rag that is attached to one end of your dowel, or simply roll the rag and twist
it into the chamber.
STEP THREE
Before replacing the plunger, coat the plunger with some oil to make it easier
to fit and less likely
to damage the o-rings.
As you slide the plunger back home into the chamber, make sure that the
indentation is facing up
so as to “marry” with the allen screw
Remember, spring side goes in first
Now comes the tricky part, make sure that you do not “nick” the o-ring as it
passes the allen screw
hole in the chamber, if you work slowly and with sufficient oil, it should slide
home easily.
To push the plunger into this position you could use the dowel or use and empty
co2 cartridge, which
I prefer because it can be adjusted by means of the knurled screw-in plug.
STEP FOUR
Now before you screw in the allen screw, wind some thread seal tape or add
silicone sealer to the
threads.
Screw allen screw in tight.
CONGRATULATIONS, YOUR GUN IS FIXED!
