Leister HEMTEK ST / K-ST
Automatic welder
Read through the operating instructions before commissioning.
Always store these operating instructions at the device.
Do not pass the device on to other personnel without the operating instructions.
In addition to the safety instructions contained in the individual chapters of these operating instructions,
the following provisions are also to be followed strictly at all times.
We congratulate you on your purchase of a HEMTEK ST / K-ST!
You have chosen a first-class hot air welder.
It was developed and produced in accordance with the very latest state of technology in the plastics-processing
industry. The device has been manufactured using premium-quality materials.
Warning
Caution
Danger to life! Before opening the device, pull the mains plug out of the socket,
because voltage-bearing components and connections will be exposed when it is
opened!
Danger of fire and explosion
exists in connection with improper use of the automatic welder (e.g., due to material overheating) and particularly in the vicinity of
flammable materials and explosive gases.
Risk of burning!
Do not touch heating element, nozzle and components in the immediate vicinity
of the nozzle when hot. The device should always first be allowed to cool down.
Do not point the hot air flow at people or animals!
Connect the device to a socket with a protective conductor. Any interruption of
the protective conductor inside or outside of the device is dangerous.
Use extension cables with protective conductors exclusively!
Risk of clamping injuries!
A danger of clamping injuries exists with the tilting mechanism when the hot-air
blowers swivel in and out.
Risk of entanglement!
During operation there is a risk of entanglement on the drive roller.
The nominal voltage specified on the device must match the local supply voltage.
If the network voltage fails, then the main switch and the drive must be switched
o (raise the drive roller).
The device must be monitored continuously during operation. Waste heat can
come into contact with flammable materials that are not in view.
Device may be operated only by trained specialists or under their supervision.
Children are not permitted to operate the equipment under any circumstances.
