4.3 Measure the Gap
4.3.1 Connect the Jet
 Connect the jet to a controller.
 Turn on the controller and “OPEN” the jet.
 Remove the tip protector and observe the
needle position.
 Insert the hex wrench into the adjustment
setscrew.
4.3.2 Reading the Dial
One unit on the small hand is 0.100”
One unit on the large hand is 0.001”
On the dial below:
The small hand is between 0.100” and 0.200”
The large hand is at 0.042”
The reading would be 0.142”
On the dial below:
The small hand is between 0.100” and 0.200”
The large hand is at 0.036”
The reading would be 0.136”
4.4 Adjust the Gap
For most hotmelt applications, the recommended hammer gap is 0.110 inches; the
optimal position will depend on the jetting material and dispensing requirements.
 If an adjustment is necessary, turn the adjustment setscrew with the hex
wrench until the preferred value is displayed on the dial.
 Cycle the jet several times (OPEN-CLOSE) and validate that the gap is stable.
 Replace the tip protector and the zeroing plate on the Gap Set Fixture.
 “CLOSE” the jet and remove.
The jet is ready to use.
