Remove and Replace the Screwdriver Bits
To replace screwdriver bits on the Six-Shooter heads, follow the instructions below.
1.
Turn off all power to the machine. Follow proper lockout/tagout procedures as
detailed in the safety section of Chapter 1 of this manual.
2.
Disconnect air from Six-Shooter using the air-connect slide valves. Slowly slide the
valves back toward you; listen for air to be released.
3.
Pull the Six-Shooter assembly toward the machine-it will move slightly.
4.
Locate the back slide near the air valves (see images); push slide away from you.
This allows for movement of the Six-Shooter assembly away from the machine.
5.
Move the Six-Shooter assembly away from the machine-it will move about 1½ inch.
This provides room for hands to access the screwdriver bit holders.
