Safety instructions
Please read this safety information carefully:
Be aware of the following three symbols throughout the user manual:
Warning!
Failing to follow these instructions can cause accidents resulting in serious personal injury.
Recommendations
Failing to follow these instructions can result in the actuator suffering damage or being
ruined.
Additional information
Usage tips or additional information that is important in connection with the use of the
actuator.
Furthermore, 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 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.

Page 8 of 76
During operation, please be aware of the following:
• 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 in order to prevent unintentional operation.
• Check regularly for extraordinary wear.
Classification
The equipment is not suitable for use in the presence of a flammable anaesthetic mixture with
air or with oxygen or nitrous oxide.
Warnings:
• Do not sideload the actuator.
• Only use the actuator within specified working limits.
• When mounting the LA36 in the application ensure that the bolts can withstand the wear
and that they are secured safely.
• If irregularities are observed, the actuator must be replaced.
Recommendations:
• Do not place load on the actuator housing and do prevent impact or blows, or any other form
of stress to the housing.
• Ensure that the cable cover is mounted correctly. Use 1.5Nm torque.
• Ensure that the duty cycle and the usage temperatures for LA36 actuators are respected.
• Ensure that the cable cannot be squeezed, pulled or subjected to any other stress.
• Furthermore, it will be good practice to ensure that the actuator is fully retracted in the
“normal” position. The reason is that there will be a vacuum inside the actuator if it is
extended which over time can lead to water entering the actuator.
• If the actuator (without integrated controller) is mounted in an application where a mechani-
cal stop prevents the endstop switches in the actuator from being activated, the actuator must
be equipped with an electrical safety device (current monitoring) or external limit switch.

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. Also, avoid applying a skew load on the actuator.
The actuator can rotate around the pivot point in the front and rear end. If this is the case it is of
high importance that the actuator is able to move freely over the full stroke length, both during
the development and during daily operation. Please pay special attention to the area around the
housing where parts can be trapped and cause damages to the application and actuator.
In applications with high dynamic forces LINAK recommends not to use the fully extended or
retracted position over longer time, as this can damage the endstop system permanently.

Mounting guidelines
• The mounting pins must have the correct dimension
• The bolts and nuts must be made of a high quality steel grade (e.g. 10.8). No thread
on the bolt inside the back fixture or the piston rod eye
• Bolts and nuts must be protected so there is no risk for them to fall out
• Do not use a torque that is too high when mounting the bolts for the back fixture or
he piston rod eye. This will stress the fixtures
Please note:
The piston rod eye is only allowed to turn 0-90 degrees.
Instruction concerning the turning of the piston rod eye:
When mounting and taking into use, it is not permitted to make excessive turns of the
piston rod eye. In cases where the eye is not positioned correctly, it is permitted to first
screw the eye down to its bottom position, at a maximum torque of 2Nm (1), and thereaf-
ter a maximum half turn outwards again (2).
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 designed for use within the following fields:
• Offshore installations
• Aeroplanes and other aircraft
• Nuclear power generation

Mounting of cables
When changing the cables on a LINAK actuator, it is important that this is done carefully,
in order to protect the plugs and pins. Before the new cable is mounted, we recommend
that the socket is greased with vaseline, to keep the high IP protection and ensure an easy
mounting. Please be sure that the plug is in the right location and fully pressed in before
the cable lid is mounted.
Please note that if the cables are mounted and dismounted more than 3 times the plugs
can be damaged. Therefore, we recommend that such cables are discarded and replaced.
We recommend to take some precaution and design the wire connection in a way, where
the cable end is kept inside a closed, protected area to guarantee the high IP protection.
3. Slide the cover onto
the actuator.
The torque of the
cover screw is
approx. 1.5 ± 0.3 Nm
TORX 25IP
1. Unscrew the cover and
remove the two blind
plugs.
2. Plug in the power
cable and/or the
