• Slightly grease over inner surface of actuator ring (Pos. 1):
- for pa-actuator with"Lagermeister SL"
- for pps-actuator with "Amblygon TA 30-1".
• Slightly grease over lip seal seat (Pos. 2) and spindle guide bush (Pos. 4)
in the actuator body (Pos. 1) with “Amblygon TA 30-1”.
• Insert lip seal (Pos. 2) in actuator body (Pos. 1).
• actuator size h-125: push in safety disc.
• Grease slightly over spindle* (Pos. 4) with “Lagermeister SL” or
“Amblygon TA 30-1” and insert together with pressure piece (Pos. 5) and
diaphragm (Pos. 21) from below into the actuator body until it stops.
Caution!
Keep diaphragm grease-free!
• Hold actuator on square of the actuator body.
• Push lower intermediate disc (Pos. 7) onto spindle (Pos. 4) until it stops.
• Grease over support ring on the piston (Pos. 9) as on the actuator body
