3.9.5 Setting the distance between hook tips and needles
Fig. 40: Setting the distance between hook tips and needles (1)
Proper setting
In the loop stroke position, the distance between the hook tips (2) and the
needles (1) should be = 0.1 mm. The set distance makes it possible to
work with needle sizes Nm 90 to Nm 110.
It is not necessary to correct the distance of the hook tips to the needles during
a change between these needle sizes. The only correction necessary during
a needle change is a readjustment of the needle guard ( p. 55).
The distance between the hook tips and the needles is set using a setting
peg (3) (part number 0244 001014).
WARNING
Risk of injury from sharp parts!
Punctures possible.
Do not check and adjust the distance of the hook
tips to the needles unless the sewing unit is
switched off.
