Chapter 3 Standard Adjustment

12-3. When the sliding resistance of the Y-carriage is over the stan-

dard value even after adjustment 2

Remove both Y-feed covers U q, measure the sliding resistance of the Y-carriage again. If the sliding resistance becomes

less, check the following items:

• Check if Y-feed covers U q that hold spacer felt w down are

deformed. If they are, straighten them.

• When the sliding resistance becomes great before and after

the Y-carriage, reattach the Y-feed cover support plates

and r as high as possible.

Notes:

• If Y-feed cover U is raised too much, it may creak during

sewing. Do not change its position more than neces-

sary. (To prevent vibration, have the Y feed cover U just

make contact with the Y carriage.)

• Finish adjustments 1 to 3 when the sliding resistance is

equal to the standard value.

There is no need to perform all adjustments.

12-4. When linear guide 505L, which is attached to machine head

No.3, is not parallel to the top surface of the bed

• Loosen the bolts of linear guide q, move the Y-feed frame to

adjust the height of linear guide 505L

q at both ends of the

stroke. (The felts should just touch the top surface of the

bed.)
