14. Looper Height

Before the setting of the looping stroke and the needle bar height and

particularly after needle breakage, the correct looper height must be

checked.

To check the looper height, use gauge 2.

Caution Risk of Injury!

Set the looper height only in the “Safe Stop” position or with the

machine turned off.

Rule and Control

When the gauge is placed on the looper turrets, the following must be

fulfilled:

–

The drilled hole 1 of the gauge must be at the upper right.

–

The point of the left looper must lie under the edge 3 of the gauge.

–

The point of the right looper must lie under the edge 4 of the

gauge.

–

The looper points must just touch the gauge.

–

Remove needle plate 5, spreader stops 7 and 9 and spreader 6

and 10 from the looper turrets.

–

Bring the needle bar into the up position by turning the handwheel.

–

Place gauge 2 on the looper turret with the loopers inserted into the

looper turrets up to the stop.

–

In this position, the rules listed below must be fulfilled.

Correction

–

Set the correct looper height through slight realignment of the

looper.
