E - MACHINE ADJUSTMENTS
6. FEEDING
1. Tilt the sewing head on the rest pin.
2. Bevel Gear Adjustment
Manually turn the hand wheel counter clockwise, until the
drive spring in the main cam engages with a detent (first
row of stitches). Remove the bevel gear cover and loosen
the screws ➊, ➋ on the horizontal bevel gears and
screw ➌ on the stop.
3. Loosen two adjusting screws ➍ in the right collar ➎.
Adjust the dimension 11mm from the end of the feed
shaft ➏ to the collar ➐ by pressing the feed shaft ➏
against the right collar ➎. Tighten the adjusting screws ➍
in the right collar ➎. The tension of the left collar on the
shaft is set.
4. Engage the left bevel gear ➑ with the vertical bevel
gear ➒ and lock its position by set screws ➋. Move the
stop against the gear and tighten set screw ➌.
5. Manually turn the hand wheel counter clockwise until the
feed shifter lever moves to its full left position then slide
the right gear ➓ into engagement with the vertical gear ➒.
Tighten set screws ➊ securely.
The bevel gear adjustment is done. By manually turning the
handwheel finish the sewing cycle and bring the machine to the
home position. Reinstall the bevel gear cover.
6. Clamp plate movement occurs only when the needlepoint
has risen above the work piece and must be completed
before the needle descends into the work.
7. For adjustment use a piece of paper to see the needle
punctures.
If feeding occurs while the needle is in the work, engage
the drive spring into a detent.
Loosen the screws on the feed cam and adjust its
position as needed so that all feed motion occurs with the
needle out of the work. Retighten the feed cam set screws.
