WARNING :
To protect against possible personal injury due to abrupt start of the machine, be sure to start the
following work after turning the power o and ascertaining that the motor is at rest.
7-7. Height and inclination of the feed dog
To secure a space
Throat plate spacer (part No. : 22503908)
Feed bar spacer (part No. : 10025906)
1.3 ± 0.1 mm
Counter knife
Feed dog
1) To adjust the height of the feed dog, loosen the
screw
and turn the feed driving link pin
using a screwdriver.
2) The standard height of the feed dog is 1.3 ± 0.1
mm.
3) To adjust the inclination of the feed dog, loosen
the screw
and turn the eccentric shaft insert-
ing a screwdriver through the adjustment hole in
the machine bed.
4) For the machine with a thread trimmer, there
can be no space between the counter knife and
the underside of the feed dog when adjusting
the feed mechanism (change in height and tim-
ing) or using a commercially-available feed dog.
In this case, place a feed bar spacer (part No.
: 10025906) under the feed mechanism and a
throat plate spacer (part No. : 22503908) under
the throat plate so as to secure a space between
the counter knife and the underside of the feed
dog.
The standard inclination of the feed dog is obtained
by adjusting the feed dog so that it becomes horizon-
tal when it rises above the top surface of the throat
plate.
