Safety instructions and measures
the machinery and/or the final system, where the actuator
is incorporated, will be declared in compliance with the
requirements of the Directive.
−
The AIR TORQUE pneumatic actuators are designed ac-
cording to the criteria of Article 1, paragraph 2. j) ii) of
the Pressure equipment directive (PED) 2014/68/EU.
Therefore, according to the directive 2014/68/EU they
are not to be considered pressure equipments.
Î Refer to the EU Declaration of Conformity available from
AIR TORQUE.
−
The AIR TORQUE actuators are in compliance with the TR
CU 10/2011 and TR CU 12/2011.

1.1 Notes on possible severe personal in-
jury
DANGER
!
Risk of bursting due to incorrect opening of pressurized
equipment or components.
Pneumatic actuators are pressure equipment that may burst
when handled incorrectly. Flying projectile fragments or com-
ponents can cause serious injury or even death.
Î
Before starting any work on the actuator disconnect all
pneumatic / hydraulic / electrical supplies and discharge
the pressure from the actuator.
Risk of severe personal injury due to suspended loads fal-
ling.
Î
Stay far from suspended or moving loads.
Î
Close off and secure the transport paths.
1.2 Notes on possible personal injury
WARNING
!
Risk of lifting equipment tipping over and risk of damage to
lifting accessories due to exceeding the rated lifting capa-
city.
Î
Use only approved lifting equipment and accessories who-
se maximum lifting capacity is higher than the actuator
weight (including the packaging, if applicable).
Crush hazard arising from moving parts.
The actuator and the valve assembly contains moving parts,
which can injure hands or
fi ngers.
Î
Do not touch or insert hands or fi nger into moving parts.
Î
Before starting any work on the actuator disconnect all
pneumatic / hydraulic / electrical supplies and discharge
the pressure from the actuator.
Î
Do not block the movement of the pinion and the pistons
by inserting objects into 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.
Î
Install the air exhaust components in such a way that
exhaust ports are not located at eye level and the actuator
does not discharge at eye level in the working position.
Î
Use suitable silencers and vent plugs.
Î
Wear eye and hearing protection when working near the
actuator.
Risk of personal injury due to preloaded and compressed
springs.
End caps are under tension due to compressed springs.
Furthermore incorrect spring cartidges disassembly could re-
sult in serious injury.
Î
Before starting any work on the actuator disconnect all
pneumatic / hydraulic / electrical supplies and discharge
the pressure from the actuator.
Î
Make sure that the actuator is in the closed position (0°)
while disassembling the end caps and the stop screws ha-
ve been correctly removed.
Î
Do not disassemble individual spring cartridges.
Î
For spring cartidges service contact AIR TORQUE.
Risk of personal injury through incorrect operation, use or
installation as a result of information on the actuator being
illegible.
Over time, markings, labels and nameplates on the actuator
may become covered with dirt or become illegible in some
other way. As a result, hazards may go unnoticed and the
necessary instructions not followed. There is a risk of personal
injury.
Î
Keep all relevant markings and inscriptions on the device
in a constantly legible status.
Î
Immediately renew damaged, missing or incorrect name-
plates or labels.
1.3 Notes on possible property damage
NOTICE
!
Risk of actuator damage due to incorrectly attached slings.
Î
Do not attach load-bearing slings to the travel stop.
Risk of actuator damage due to the use of inappropriate
tools.
Certain tools are required to work on the actuator.
Î
Do not use damaged tools. Refer to section 15.1 ‘Tools‘.
