Preface
We are delighted that you have chosen a product from LINAK. LINAK systems are high-tech products based
on many years of experience in the manufacture and development of actuators, electronic control boxes,
controls, and chargers. We are also constantly improving our products to meet customer requirements.
This user manual will tell you how to install, use, and maintain your LINAK LA35 actuator.
We are sure that the LA35 actuator will give you a problemfree operation. Before our products leave the
factory they undergo full function and quality testing. Should you nevertheless experience problems with
your LINAK products, you are always welcome to contact our service departments or service centres.
Most LINAK subsidiaries have authorised service centres, which are always ready to help you.
LINAK provides a warranty on all its products. This warranty, however, is subject to correct use in accordance
with the specifications, maintenance being done correctly and any repairs being carried out at a service

Safety instructions
Please read the following safety information carefully.
Ensure that all staff who are to connect, mount, or use the actuator are in possession of the necessary
information and that they have access to this user manual.
Persons who do not have the necessary experience or knowledge of the product/products must not use
the product/products. Besides, persons with reduced physical or mental abilities must not use the product/
products, unless they are under surveillance or they have been thoroughly instructed in the use of the
apparatus by a person who is responsible for the safety of these persons.
Moreover, children must be under surveillance to ensure that they do not play with the product.
Before you start mounting/dismounting, ensure that the following points are observed:
• The actuator is not in operation.
• The mains current supply is switched off and the plug has been pulled out.
• The actuator is free from loads that could be released during this work.
Before you put the actuator into operation, check the following:
• The actuator is correctly mounted as indicated in the relevant user instructions.
• The equipment can be freely moved over the actuator’s whole working area.
• The actuator is connected to a mains electricity supply/transformer with the correct voltage and which is
dimensioned and adapted to the actuator in question.
• Ensure that the voltage applied matches to the voltage specified on the actuator label.
• Ensure that the connection bolts can withstand the wear.
• Ensure that the connection bolts are secured safely.
During operation
• Listen for unusual sounds and watch out for uneven running. Stop the actuator immediately if anything
unusual is observed.
• Do not sideload the actuator.
• Use only the actuator within the specified working limits.
• Do not step or kick on the actuator.
When the equipment is not in use
• Switch off the mains supply or pull out the plug in order to prevent unintentional operation.
• Check regularly the actuator and joints for extraordinary wear.
• Reinstall always the cabellock and a tight screw with 1,5 Nm +/- 20%
Classification
The equipment is not suitable for use in the presence of a flammable anaesthetic mixture with air or with
oxygen or nitrous oxide.
Important information
Information about the actuators is described under the following two headings:
Warning!
Failing to follow these instructions can cause accidents resulting in serious personal injury.
Failing to follow these instructions can result in the actuator suffering damage or being ruined.

Misc. on the TECHLINE®actuator system
Warranty
There is a 12 months’ warranty on the TECHLINE products against manufacturing faults calculated from
the production date of the individual products (see label). LINAK’s warranty is only valid in so far as the
equipment has been used and maintained correctly and has not been tampered with. Furthermore, the
actuator must not be exposed to violent treatment. In the event of this, the warranty will be ineffective/
invalid. For further details, please see LINAK A/S ordinary conditions of sale.
Maintenance
• The actuator must be cleaned at regular intervals to remove dust and dirt and inspected for mechanical
damages or wear.
• Inspect attachment points, wires, piston rod, cabinet, and plug, as well as check that the actuator
functions correctly.
•
The actuator is a closed unit and requires no internal maintenance.
• To ensure that the pregreased inner tube remains lubricated, the actuator must only be washed down when
the piston rod is fully retracted.
Maintenance of spherical eyes
In order to maintain a prober performance of the spherical eyes and to increase the resistances against
hard environmental wear, we strongly recommend that the spherical (ball bearings) eyes mounted on
actuators from LINAK are greased with anticorrosive grease or similar.
Warning!
If irregularities are observed, the actuator must be replaced.

Mounting guidelines
LINAK®linear actuators are quickly and easily mounted by slipping pins through the holes on each end of
the units and into brackets on the machine frame and the load.
The mounting pins must be parallel to each other as shown in Figure 1. Pins, which are not parallel to each
other, may cause the actuator to bend and be damaged.
The load should act along the stroke axis of the actuator since off centre loads may cause bending and
lead to premature failure. See Figure 2.
Make sure the mounting pins are supported in both ends. Failure to do so could shorten the life of the
actuator. Cantilever mounts are unacceptable.

Warning!
If the actuator is used for pull in an application where personal injury can occur, the
following is valid:
It is the application manufacturer’s responsibility to incorporate a suitable safety arrangement,
which will prevent personal injury from occurring, if the actuator should fail.
Warning!
LINAK’s actuators are not constructed for use within the following fields:
• Offshore installations
• Aeroplanes and other aircraft
• Explosive environments
• Nuclear power generation
Application hints
The actuator is weatherproof for use in outdoor applications. The actuator can be washed down with a
high pressure washer, but it should not be used under water.
The duty cycle at max. load is 10% on time. This means if the actuator runs continuously for 2 minutes it
must remain off for 18 minutes before operating again.
