Installing gun with Accu-Mate connection

Loosen power clamp knob to allow power pin of gun to clear the gun locking tab.

When installing gun, the liner should extend into the PD continu- ous guide (or exit guide if used) as far as possible without interfering with the guide.

Align the groove in the power pin of the gun with the gun locking tab.

Secure gun by tightening power clamp knob.

Installing gun without Accu- Mate connection

When using a gun without the groove in the power pin, loosen power clamp knob and rotate gun locking tab 180 degrees. This pre- vents the locking tab from extend- ing into the power pin gun connec- tion.

When installing gun, the liner should extend into the PD continu- ous guide (or exit guide if used) as far as possible without interfering with the guide.

Secure gun by tightening power clamp knob.
