For this reason, it is fitted with drop feed and an additional vibrating presser which can be

to make the same, a shorter or a longer stroke than the feed dog, as appropriate.

Thanks to the incorporation of maintenance-freeanti-friction bearings, pad lubrication in the
gear case,

time required for machine care is extremely low.

Only superflnished needles ensure trouble-free sewing and prevent thread breakage. Rough-

surfaced needles tend to overheat quickly and burn the thread. This is particularly true of
synthetic threads which are very sensitive to heat and fuse easily.

For stitching synthetic threads, we recommend that you use superfinished, chromium-plated

Checking

the

Top

Feed

Motion

Since it cannot be avoided that parts having unfavorable tolerances are mated occasionally,

it may happen that the strokes of the vibrating presser and of the feed dog differ slightly.

To

check

this,

proceedasfollows:

Set the machine for its maximumstitch length and the top feed pointer on 0. Lowerthe presser

bar so that the vibrating presser and the presser foot rest on the feed dog. Rotate the balance
wheel and watch the motion of both the vibrating presser and the feed dog.

If the strokes of the vibrating presser and of the feed dog are exactly the same length, both

feeders

will

stroke.

If, however, the vibrating presser makes a little jerk in the direction of feeding as it rises clear

of the feed dog, its stroke is a little too long. If,on the other hand, the vibrating presser snaps

the

slightly

as it

of its

the

latter is a bit

short.

To remedy this condition, loosen nut f (Fig. 41) and reposition connecting rod hinge screw
