Tools required: Fillister screwdriver, #3 x 150 mm in
length, needle-height cylinder tool.
Check:
Turn the hand wheel in the direction of motion until
the hook point becomes even with the right side of
the needle as shown in (Figure 12.1). The hook point
should be 1.0 mm above the needle eye. If the height
of the needle appears to be out, install the loop lift
clamp and 2.2 mm feeler gauge as shown in the
adjustment of loop lift and needle distance section.
Check loop lift. If the machine requires a loop lift
adjustment, remove the stop-finger and hook body
from the machine. Follow the steps below using the
Needle Height Cylinder tool (part number QM40131
for all Crown Jewel machines to date [January 2016]).
Needle Height with Cylinder Tool
This adjustment can be completed with the front
frame cover on or off.
The height of the needle must be set from the front
side of the machine as shown. The eye of the needle
must align exactly to the groove as shown in (Figure
12.6 on page 36).
1. Install the cylinder tool with the flat side up.
(Figure 12.2)
2. Rotate the cylinder tool so that the flat side is down.
(Figure 12.3)
3. Bring the needle to the lowest point by rotating the
hand wheel (Figure 12.4).
