Operation Procedures

1)Apply oil to CO2 tank connector
2)Cock bolt
3)Connect tank
4)Open CO2 valve
5)Dry fire 10-15 times
6)Attach barrel
7)Attach hopper elbow
8)Attack hopper
9)Fill hopper with paintballs
10)Disengage power feed
11)Aim gun at target
12)Pull trigger
13)Repeat as neccessary

Specific User Considerations

• Fatigue or weak arms can't lift gun steadily
• Extreme low temperatures
• Too rapid a rate of fire
• Assembly difficult for disabled users (lost arm, or finger)
• Bad vision
• Clogged Barrel or Debris in system

Possible Areas of Improvement

• Shooting accuracy
• Shooting range and distance
• Gas efficiency
• Weight and size of marker
• Trigger pull distance
• Multiple projectile firing
• Reduction in number of components
• Ease of disassembly for cleaning and service
