Additional Trolley Set Screws
There are seven set screws on the Trolley assembly in addition to the set screws on the Y
motor drive gear. They are as follows:
Pillow block bearing to Chuck shaft (2)
Chuck mount to Chuck shaft (2)
Chuck Mount socket head screws (3)
It is recommended the Operator check these set screws on a regular basis. Apply Loctite Blue
242 to all set screws. Ensure set screws are secure.
Chuck Alignment
During normal operation it is possible for the Chuck to fall out of alignment on the Dragon A150
machine. If the Chuck is out of alignment it will result in imprecise machine operation. If the
Chuck is out of alignment it will be necessary for the Operator to bring the Chuck back into
alignment.
Aligning the Chuck
1. Jog the Chuck to front of machine, approximately 1 ft. behind the Gate
2.
Using a 5/16 in. Allen wrench, remove the four screws that secure the Chuck cover. The four
screws thread in through the bottom of the Trolley plate.
3. Using a ¾ in. wrench on the bolt head and a second ¾ in. wrench on the nut, loosen the
four pillow block bearing mounting bolts approximately one full turn.
4. Using a ½ in. wrench, loosen the Y axis motor mount bolts approximately one full turn.
5. Replace the Chuck cover.
6. Load a short piece of material into the machine. The material should be long enough so it
reaches through the front Gate on one end, and extends through the Chuck to the end of
the Chuck Shaft on the other end.
7. Tighten the Gate on the material so it moves freely with no play
