Adjusting the 3-Way (poppet) Valve
Unplug tool and disconnect air supply before making adjustments or installing bits.
Observe appropriate Lockout/Tagout procedures to insure the tool cannot accidentally be powered.
The 3-Way (poppet) Valve is located on the inside, front wall of the cabinet approximately midway down (Fig. 24).
This valve controls the air cycle to release the pneumatic clamp. If the 3-Way valve is not positioned properly the
pneumatic clamp may not release properly.

plate at the front of the machine (Fig. 24).
4.
Position the bottom (front) of the Valve so it is 2-5/8
” from the large, gray mounting plate at the front of
the machine (Fig. 24).
