After transport check the V-belt tension set at the factory.

With correct tension the V-belts 5 (from the sewing drive to the

head) can still be pressed in approx. 10 mm at the center with finger

pressure.

Tensioning V-belt 5:

–

Remove the belt guard after loosening the mounting screws.

–

Loosen screw 2.

–

Swing the sewing drive until the desired V-belt tension is achieved.

–

Tighten screw 2.

Tensioning V-belt 1:

–

Loosen clamping screw 4.

–

Press the belt tensioner 3 onto V-belt 1 until the correct V-belt

tension is achieved.

–

In this position tighten clamping screw 4.

–

Replace the belt guard again.

Use only ESSO SP-NK 10 lubricating oil for filling the oil reservoir.

Fill the oil reservoir for the hook lubrication and the reservoir for

the lubrication of the machine head up to the "Max" mark with oil

(see Chapter 3.2 of the Operating Instructions).
