comply to the safety notice and to use proper equipment to protect
health and prevent accidents.

8) LIFTING AND HANDLING
• It is important that the actuator is used only within the working
limits indicated in the technical specifications.
1. General
This instruction manual contains important information regarding the
installation, operation, maintenance and storage for AL 79 rack and
pinion pneumatic actuators. Please read these instructions carefully
and keep them for future reference. It is important that the use and
maintenance of the actuator is made only by properly trained personnel.
• Do not operate the actuator over temperature limits: this could damage internal and external components (disassembly of spring return
actuator may become dangerous).
• Do not operate the actuator over pressure limits: this could damage
internal parts as well as cause damage to the housing and end-caps.
• Do not use the actuator in corrosive environments with incorrect
protection: this could damage the internal and external parts.
2. Warning
• Do not operate the actuator using inflammable, oxidizing, corrosive,
explosive or unstable gases or liquids (use only not dangerous fluids
– group 2 according to 97/26/EC directive). Moreover, for actuators
installed in potentially explosive zones, make sure that the internal
parts of the actuator do not come into contact with the external
atmosphere.
• Referring to the Machinery Directive 2006/46/EC, the actuators
can be classified as “PARTLY COMPLETED MACHINERY” (see the
DECLARATION OF INCORPORATION). Therefore the actuator can
not put into service until the machinery and/or the system, where
the actuator is incorporated, will be declared in compliance with the
requirements of the Directive 2006/42/EC.
• AL 79 actuators are designed, produced and classified according to
the ATEX Directive 94/9/EC (see actuator label and safety instructions). The use of the actuators in potential explosive atmosphere
zones has to comply with the ATEX classification indicated on the
actuator label and according to the ATEX safety instructions.
• Do not disassemble individual spring cartridges, this may result in
personal injury. If maintenance to springs is necessary, send them to
Axel Larsson.
• Close and disconnect all air supply lines and make sure that air connections are vented during maintenance and installation on valve.
• Do not disassemble the actuator or remove end caps while the
actuator is pressurized.
• The 4th GENERATION Upgrade Series actuators are designed to
be used only on valves.
• Before installing the actuator onto the valve make sure that the rotation direction and the position indicator are in the correct position.
• If the actuator is incorporated in a system or used within safety
devices or circuits, the customer shall ensure that the national and
local safety laws and regulations are observed.
• The use, the installation and the maintenance of the AL 79 actuators
must be made by adequately trained personnel. For the use, instal-

3. Working conditions and technical data
• Operating media:
Dry or lubricated air or inert gases, provided that they are compatible with the actuator internal parts and lubricant. The operating media must
have a dew point equal to –20°C (-4°F) or at least 10°C below the ambient temperature. The maximum particle size contained into the operating media must not exceed 30 m.
• Supply pressure:
The maximum supply pressure is 8 bar (116 Psi), only for AL 79-801 it is 7 bar (101,5 Psi).
For double acting and spring return actuators the working pressure is from 2.5 bar (36 Psi) to 8 bar (116 Psi).
• Operating temperature:
“Standard” actuators from -40°C (-40°F) to +80°C (+176°F)
Actuators for high temperature “HT” from -15°C (+5°F) to +150°C (+300°F)
Actuators for extreme low temperature “LLT” from -55°C (-67°F) to + 80°C (+176°F)
Caution: for low and high temperature service, special grease and special components are required. Please contact Axel Larsson. Working at high
or low temperature can affect the life and the output torque of the actuator.
• Operating time (see technical data sheet):
Caution: the operating time depends on several factors such as supply pressure, supply system capacity (pipe diameter, flow capacity of pneumatic accessories), valve type, valve torque and figures, applied safety factor, cycle frequency, temperature, etc.
• Rotation and stroke adjustment (see technical data sheet):
For standard actuators (90° rotation), 120° actuators (120° rotation), 135° actuators (135° rotation) and 180° actuators (180° rotation).
Stroke adjustment at 0°(closed pistons): +15°max/ - 5°. Stroke adjustment at 90°, 120°, 135° and 180°(open pistons): +5°/-15°max. For actuator
AL 79-045U the stroke adjustment at 90° (open pistons) is available only on request.
• Lubrication:
The actuators are factory lubricated for the life of the actuator in normal working conditions.
The standard lubricant type GSTD is suitable for use from -40°C (-40°F) to +80°C (+176°F).
For extreme low temperature (LLT) and high temperature (HT) service, special grease is required: please contact Axel Larsson.
• Construction:
Rack and pinion actuator design suitable for both indoor or outdoor installations.
• Protection and corrosion resistance:
All the actuators are supplied with corrosion protection for normal environments. For corrosion resistance of the different types of protection
see technical data sheet. Before installing the actuator in aggressive environment, ensure that the selected protection level is suitable.
• Actuator designation and marking (see technical data sheets):
The actuator type, size, operating pressure, output torque, direction of rotation, spring action, operating temperature and type of connections
interfaces are determined by designation. All AL 79 actuators are supplied with an identification label showing the serial number and all necessary information on use, service, operation and product designation. Where applicable, the label indicates the classification according to ATEX
Directive 94/9/ EC.
