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 LA36
actuator.
We are sure that the LA36 actuator will give you a problem-free 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 centre, which is authorised to repair
LINAK products.

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 main-
tained 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
