7. Overview of safety measures and

warnings

7.1 Safety

The NL-33 is equipped with all mandatory safety requirements that apply according to the
European guidelines for machine safety.

The safety frame

The heating element of the NL-33 is shielded with a safety rack. This is to prevent the risk
of pinching during heat sealing.

The emergency stop button

As required in the guidelines for machines, the machine is provided with an emergency stop
button. Press in case of emergency!
Turn the knob counter-clockwise to unlock again and the machine will reset automatically.

Two-hand control

For added safety, the machine is tted with a two-hand control. In order to be able to oper­ate the machine by hand it is required to press both green buttons, placed on the left and

right side op the press arm, simultaneously. This prevents hands and ngers being pinched

between both plates.

10. Technical Manual

10.1 Maintenance

Make sure that the working cycle of the machine has ended before you start working on the
machine. Depending on the work to be performed, the power supply or the air supply can
be disconnected.
The air cylinder and other parts of the machine are virtually maintenance-free.
However, the condition is that clean and dry air is used for the heat seal machine. The ap­plied water separator / pressure regulator is an extra safety.

Have your machine serviced by technically qualied personnel. Moisture and polluted air

disturb the sustainable lubrication of the air cylinder.

It is recommended to have the following tools at hand:

• Phillips and at screwdrivers

• A set of at and pipe keys

• Allen key set

• A multimeter

 ATTENTION!

Remove the plug from the wall socket BEFORE starting maintenance or repairs

Teon cover:

The teon lm protecting the element must be cleaned regularly to prevent sticking of la­bels and patches or the transfer of dirt to the garments. Clean the Teon cover with a dry,

clean cloth while the machine is still warm. Repeat the process regularly as often as neces-

sary. Damaged or soiled Teon protection should be replaced. These are available from your

Thermopatch supplier.

Rubber cushion:

Clean the still warm rubber plate with a clean, lint-free cloth. Clean it as often as necessary.
Damaged or soiled rubber sheets must be replaced. These are available from your Thermo­patch supplier.

Replacing the rubber cushion:

• Turn o the device and allow it to cool

• Make sure both the bottom metal plate and the rubber cushion are clean and free of
grease

• Apply SPA-AS1504 silicone adhesive (with a glue comb) to the metal plate and place the
rubber plate immediately with no air bubbles

• Allow to dry overnight at room temperature under light pressure without heating.

Air lter:

The air lter, or the water separator / pressure regulator, must be checked daily and, if nec­essary, emptied by opening the cap on the underside of the lter.

Replace the fuses

Make sure that the machine is switched o and that the power cord is unplugged! Replace

the T16 A fuses at the back of the machine. Then plug in the power cord again and the ma­chine is ready for use again.

For other parts, contact your supplier for their replacement or repair.
