not easily slide out, insert a BT barrel swab into the front of the body
and push out the bolt and bolt guide assembly.
Note: You can remove the bolt guide assembly for maintenance and
cleaning by taking off the removable shell panel only. It is not necessary
to separate the shells.
Maintenance of Bolt and Bolt Guide
• Inspect the o-rings on both the bolt and bolt guide for any wear or dam-
age. Replace damaged or worn o-rings if necessary.
• Lubricate all o-rings on bolt and bolt guide with the supplied grease or
Dow 33. Only a small amount of grease is needed.
Maintenance of Poppet
Note: Notice how far the bolt guide cap is into the bolt guide. When rein-
stalling the bolt guide cap make sure it is at about the same location. This
will help keep your velocity settings.
• Use a 7/64" Allen wrench and insert it into the side of the bolt guide
cap. Turn counter clockwise until bolt guide cap is completely removed.
• Remove the poppet spring, being careful not to lose it.
• Use 1/8" Allen wrench and carefully insert it into the front of the bolt
guide. Push the poppet out the back of the bolt guide. Be careful not to
damage the poppet front sealing face.
• Inspect and lubricate poppet o-ring and be careful not to lubricate the
front poppet seal.
Replacing the Poppet Seal
If there is a slight air leak evident coming through the bolt area, the poppet seal
may be worn and need to be replaced. With the poppet removed, grab the
poppet seal with pliers and unscrew the poppet by hand from the poppet seal.
Do not grab the poppet with pliers or put in a vice as it may damage the brass.
Install the new poppet seal by hand. Once tightened by hand, the poppet will
hold the poppet seal in place and it should not come apart during operation.
Re-Installation of Poppet and Bolt Guide Cap
• Place poppet into the back of the bolt guide and gently push forward.
If installed properly the poppet will be all the way forward resting on
the bolt guide internal face (Fig. 2.2).
• Install the poppet spring back into the back of the poppet.
• Using the 7/64" Allen wrench, screw
the bolt guide cap clockwise back
into the bolt guide. Screw the bolt
guide cap all the way in to help seat
the poppet and then turn it out one
turn. Further adjustment over a
chronograph will be needed to
achieve desired velocity.
Re-Installation of Main Spring, Bolt and Bolt Guide Assembly
• Slide the main spring onto bolt, and then the bolt onto bolt guide, so it
is one assembly. You will notice, one end of the spring is smaller and will
lock onto the bolt (Fig. 2.3).
• Insert bolt assembly back into the body.
• Line up the alignment hole on the guide with the alignment pin on the
body and slide the bolt assembly fully forward to the body.
• Holding the bolt assembly tight into the back of the body with one
hand, reinstall the bolt
guide retention screw
and tighten using the
1/8" Allen wrench.
Circuit Board Removal
The circuit board should only need to be removed to clean the break beam eyes.
• Remove the body assembly from the shell.
• Using a 5/64" Allen key, remove the two circuit board screws and
carefully remove the circuit board.
• Gently wipe the eye sensors with a damp cloth. Do not use chemicals
