2. Installing the Sewing Unit

ATTENTION !

The machine may only be installed by trained, skilled personnel.

2.1 Removing the Transport Fastening

The machine head, machine plate and transport carriage are

assembled as a unit for delivery.

The transport fastening 2 prevents

–the machine head swinging up

–the transport carriage running back through centrifugal forces.

Before installing the sewing unit remove the transport fastening 2:

–Loosen brace 3 on spar 4.

–Loosen brackets 1 and 5.

–Remove the transport fastening 2.

2.2 Transport

The stand of the sewing unit is equipped with four castors for in-house

transport.

ATTENTION !

Before commissioning the sewing unit place the sound absorbers 2

(in the accessories pack) on the four feet of the stand.

Turn in the castors until the stand is stable.

–Run the castors out for transport by turning the setting screws 1 to

the left.

The feet of the stand must have sufficient ground clearance for

transport.

–After transport lower the sewing unit by turning the setting screws

1 to the right.

The feet of the stand must be firmly on the ground.

2.3 Setting the Work Height

The work height is adjustable between 87 cm and 110 cm (measured

to the upper edge of the table).

The sewing unit is set at the factory at the lowest work height of 87 cm.

–Loosen the fastening screws 3 on all four spars of the stand.

–Set the base plate horizontally to the desired work height.

In order to prevent twisting pull out or push in the base plate

uniformly on both sides.

–Tighten the fastening screws 3.

2.4 Checking the V-belt Tension

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

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

intermediate gear) and 1 (from the intermediate gear to the machine

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.

2.5 Filling Oil

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

SP-NK 10 is available from the DÜRKOPP ADLER AG sales offices.

–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).

3. Attaching the Machine Parts Removed for Shipment

The slots in angle 5 make possible an adaption to different work

heights.

Align the height of angle 5 so that pedal 3 can be optimally

operated.

–Hook in the pedal bar 2.

–Loosen clamping screw 1 slightly.

–Set the height of the pedal bar 2 so that the pedal is horizontal

3.5 Throw-over Stacker (Optional Equipment)

The throw-over stacker (Order no. Z112 427514) is attached to the

frame of the sewing unit with holder pipe 1.

At delivery of the sewing unit the holder pipe 1 is already premounted

on the frame brace 3.

If the throw-over stacker is delivered separately packed, the holder

pipe 1 must first be attached to the frame brace 3 of the sewing unit.

–Mount guard plate 12 on the housing 11 of the throw-over stacker

with screws, washers and spring washers.

–Fasten holder pipe 1 on the frame brace 3 of the sewing unit with

screws, washers and brackets 6.

–Fasten spar 4 on the brace 5 of the stacker stand with screws,

washers and bracket 7.

–Insert the ribbed plug 8 in spar 4.

–Push the throw-over stacker toward the frame of the sewing unit so

that spar 4 catches in the holder pipe 1.

The height of spar 4 is adapted to the holder pipe 1 via the slots in

brace 5 of the stacker stand.

–Insert the coupling plug of the compressed air feed into hose

coupling 10.

–Insert the coupling plug of the control lead into hose coupling 9.

–Attach one end of the potential cable 13 to the stopper plate 14 of

the throw-over stacker with the enclosed wing nut.

Attach the other end to the frame of the sewing unit with the

existing wing nut.

The potential cable 13 serves to conduct static charges to ground.

–After starting the sewing unit with the throw-over stacker open, set

the clearance to the sewing unit.

The sewing pieces must securely enter the opening between the

smoother and the stacked-goods support.

–Tighten clamping lever 2.
