6 Service and Maintenance / Single Valve Gate Nozzle GN...S01 Safety Instructions for the Service at the Single Valve Gate Nozzle GN... S01 Hot Surfaces Hazard ontact between the skin and hot surfaces could result in burns. Use personal protective equipment, such as gloves, apron, sleeves and face protection, to guard against burns. When servicing or handling the hot runner system outside the manifold plates or the injection molding machine, care must be taken to heed the hot surface exposure warnings. Hazard of ressurized ir ressurized air blow can result in hot plastic parts or foreign bodies entering the eyes, causing vision damage. Use personal protective equipment: Face protection, hearing protection and gloves. Hazard of Material Damage Without consulting Synventive it is not permitted to do modifications to the hot runner system e.g. geometrical changes to the nozzle tip, except the part shape adjustment in the area of material allowance. ny impact against the nozzle tip may result in its damage. Never hammer or impact the nozzle tip from the front (i.e. from the side of the mold). wisting could damage the nozzle tip. When replacing the nozzles, the sealing rings must always be replaced.
