Caution Risk of Injury !
Before replacement of the machine arm pull the mains plug.
The following points are to be taken into account when replacing the
machine arm !
–
The glide pads with their ground-in markings found in the machine
housing must point forward.
–
Before the machine arm is completely lowered insert the upper
toothed quadrant between cutter bar and arm.
–
After the centering screw 3 and the machine mounting screws are
screwed in, the setting pin 1 is inserted as deep as possible into
the housing so that it catches.
With an open-end wrench it is turned until it touches and secured
with the screw 2.
After all screws have been tightened the old setting of the machine
arm has been reached.
ATTENTION !
The movement of the spreaders ( chapter 29 ), the position of the
upper toothed quadrant ( chapter 20 ), the setting of the hook ( chapter
28 ) and the clearance of the needle to the hook tip in the various hook
block positions ( chapter 35 ) are to be checked as described in these
instructions and reset as necessary !
