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 problemfree operation.
Before our products leave the factory they undergo full function and quality
testing. Should you nevertheless experience problems with your LINAK pro-
ducts, 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.
During operation
• Listen for unusual sounds and watch out for uneven running. Stop the
actuator immediately if anything unusual is observed.
When the equipment is not in use
• Switch off the mains supply or pull out the plug in order to prevent
unintentional operation.
Classification
The equipment is not suitable for use in the presence of a flammable
anaesthetic mixture with air or with oxygen or nitrous oxide.

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.

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.
Warning!
If irregularities are observed, the actuator must be replaced.

- 22o F to +150o F
Full performance +5o C to +40o C
End play: 2 mm maximum
Weather protection: Rated IP 66 for outdoor use. Furthermore the actuator
can be washed down with a high-pressure washer.
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
bind 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
