Quit Maker Pro 18 VERSA

7. Adjusting the Motor Drive/Timing Belt Tension

The Quilt Maker Pro 18 VERSA machine utilizes a

single motor drive/timing 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 finger

(Figures

7.1–7.2)

. Press the vertical center of the belt with approximately

2 lbs of pressure. The belt should deflect about ½”. Proper

belt tension provides for some belt flexibility under light finger

pressure, but should not be so tight as to bind the machine.

Double-check the tension by rotating and rocking the hand wheel.

Confirm that there is no backlash or play between the belt teeth

and any of the driven components. Confirm also that there is an

immediate transfer of motion to all components driven by the

belt, from the handwheel to the hook.

Important:

Do not over-tighten the belt as this will make the

machine too tight, the handwheel more difficult to turn, create

more belt noise, and also cause other undesirable issues.

If a correction is necessary:

• Insert a 4 mm handle hex tool through the hole in the main

frame casting

(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-tightening

the belt tensioner screw

(Figure 7.2).

• Note: This adjustment can only be made with the front cover off

so the tensioner can be pressed down to set proper belt tension.

Important: Do not attempt 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 flat, not tilted, when

tightened, so the tensioner will not slip, resulting in a loose belt
