D - MACHINE ADJUSTMENT

4. BRAKE ADJUSTMENT

4.1 Adjustment of drive shaft brake

The Drive shaft brake optimalizes the stitch density of the buttonhole seaming on both, left and right side.

1. Loosen the screw

of the ring

of the drive shaft brake.

2. Set the brake pressure using a suitable tool (screw driver). Set the groove between the exible washers

pressing them and the ring for approximately cca 0,75mm.

3. Tighten the screw

of the ring

WARNING!

The shaft brake is an emergency brake. If the main shaft brake pressure is too high, machine mechanisms may work

incorrectly; especially the stopping mechanism. Set the lowest possible pressure.

4.2 Main cam brake adjustment

The main cam brake affects the stitch density, which is adjusted as in chapter 2. It is a specication given by the ma-

nufacturer to set up the distance between stitches. It is necessary to adjust the brake belt again after some machine

operation because of wear out.

1. Loosen the safety nuts

2. Turn the screw

increase the pressure of 1/4 turn.

3. Tighten the safety nut

NOTE!

Combination of pressures of both

brakes should make it possible

to reach 1,6 mm moving down-

wards on one stroke with stitch

density set up as in section C7.

No more no less!
