handled incorrectly. Flying projectile fragments or components
can cause serious injury or even death. Before working on the
actuator:
Ö
Before starting any work on the actuator disconnect all pneu-
matic / hydraulic / electrical supplies and discharge the
pressure from the actuator.
Risk of personal injury during actuator air exhaust!
In case of pneumatic version the actuator is operated with air. As
a result, air is exhausted during operation.
Ö
Wear eye and hearing protection when working near the ac-
tuator.
