●The danger and safety instructions attached to the machine must be followed!
●The machine may only be used for the purpose intended and may not be operated wit-
hout its safety devices. All relevant safety regulations must be adhered to.
●When changing the feed rollers or the hot air nozzle, when leaving the machine unatten-
ded or during maintenance work, the machine must be disconnected from the power
supply by operating the main switch or by pulling out the plug!
●The daily maintenance work may only be carried out by appropriately trained personnel!
●During repair and maintenance work on pneumatic devices the machine must be discon-
nected from the pneumatic supply system! The only exceptions permitted are during ad-
justment work and function tests carried out by appropriately trained personnel!
●Repairs and special maintenance work may only be carried out by qualified service staff
or appropriately trained personnel!
●Work on electrical equipment may only be carried out by appropriately trained personnel!
