Safety Instructions for the Service at the Single Valve Gate Nozzle GAN . . . S01
Hot Surfaces HazardContact 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 Pressurized AirPressurized 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 DamageWithout 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.Any 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).Twisting could damage the nozzle tip.When replacing the nozzles, the sealing rings must always be replaced.

5) Check the position of the cooling bar (6) on the pneumatic cylinder housing bottom (11).
NOTICEThe cooling bar (6) must be easily movable to be positioned on the pneumatic cylinder housing bottom (11). If this is not possible, contact Synventive customer service.
6) Fix with the Hexagon socket cap screw (16) the cooling bar (6) on the pneumatic cylinder housing bottom (11).

10.7.8 Valve Pin Height Adjustment1) Use pneumatic pressure with reduced pressurized air of approx. 2.76 bar (40 psi) on connection (A) to drive the valve pin
in valve gate closed position.2) Unscrew the hexagon socket cap screw (20).3) Adjust valve pin position with an pin Ø 5 mm in holes of the threaded ring (10).4) Turn the threaded ring (10) by using a pin (ø 5) to get the valve pin front into basic position (D) 0,3 mm.
Reference (C) = 10.25 mm between bottom center ring (24) nozzle and guide sleeve (12).
NOTICETurning one hole forward results in a height adjustment of 0,25 mm at the valve pin.
5) Tighten hexagon socket cap screw (20) - screw up to stop and then turn 90° degree to tying up.
