15.1.1 Tightening torques
− All the tightening torques are intended in Nm.
− Tightening torque tolerance: ±10%.
− The tightening torques are based on a friction coef fi cient of
0.12 with a lubricated fi xing element (bolts or nuts) threads.
− After long operating times or use at temperatures above 80°C,
the breakaway torque may be signi
fi cantly higher.

15.1.2 Lubricants
The actuators are delivered ready lubricated for the service life of
the actuator under normal operating conditions. The standard lu-
bricant is approved for the temperature range from -40°C
(-40°F) to +80 C (+176°F).
Recommended greases for actuators for use under standard con-
ditions:
