Quit Maker Pro 18 VERSA
7. Adjusng the Motor Drive/Timing Belt Tension
The Quilt Maker Pro 18 VERSA machine ulizes a
single motor drive/ming belt system.
Tools required: 3 mm handle hex tool, 0. 5 mm feeler
gauge, 8 mm open end wrench Tools required: 4 mm
handle hex tool
Check: With the machine front cover removed. Check the belt
tension for tautness by pressing it with the index nger (Figures
7.1–7.2). Press the vercal center of the belt with approximately
2 lbs of pressure. The belt should deect about ½”. Proper
belt tension provides for some belt exibility under light nger
pressure, but should not be so ght as to bind the machine.
Double-check the tension by rotang and rocking the hand wheel.
Conrm that there is no backlash or play between the belt teeth
and any of the driven components. Conrm also that there is an
immediate transfer of moon to all components driven by the
belt, from the handwheel to the hook.
Important: Do not over-ghten the belt as this will make the
machine too ght, the handwheel more dicult to turn, create
more belt noise, and also cause other undesirable issues.
If a correcon is necessary:
• Insert a 4 mm handle hex tool through the hole in the main
frame casng (Figure 7.2). Loosen the socket-head belt tensioner
screw. Adjust the belt tensioner by pressing down on the
tensioner and while holding down on the tensioner re-ghtening
the belt tensioner screw
(Figure 7.2).
• Note: This adjustment can only be made with the front cover o
so the tensioner can be pressed down to set proper belt tension.
Important: Do not aempt to set belt tension with the front
cover on as improper belt tension will result.
Important Note: Ensure that the special washer with step is
down into the tensioner bracket slot and at, not lted, when
ghtened, so the tensioner will not slip, resulng in a loose belt
(Figures 7.3-7.6).
