Recommendations
• If there is a risk of “pull forces” in the application, the actuator must be equipped with spline functionality to avoid damage in pull.
• Patient lift and stand aids:
- Long installation dimension: must always be used for patient lifts
- Do not hold the inner or outer tube while the actuator is running.
There can be a risk of squeezing between the manual lowering unit and the outer tube.
- Always use the ratchet spline functions for patient lifts.
• LA40 8000 N PL actuators for patient lifts are marked with a label to ensure that the user is aware that it is not allowed to pull the
actuator or otherwise expose it to side forces when handling the patient lift.
• If the actuator is used in dynamic push and pull, noise and extended play in axial direction may occur during lifetime
due to wear and tear.
• The max. pull load and guidelines for safety arrangements in accordance with the User Manual must be respected.
• If the damper is activated too frequently, there is a risk of reduced damping effect.
• The damper functionality is not designed to work in environments with low temperatures (below 0 °C). The actuator may become defective and/or
the damping effect may be reduced.
• If the load on the actuator is too low, the damper will not be activated and the actuator will work with quick-release effect only.
• If the load on the actuator is too low and the QR is activated (i.e. when a caregiver uses QR for cleaning purposes), high clicking sounds may occur
during the actuator lowering. This is caused by the damper functionality and does not mean any actuator or damper damage.
Black housing material:
The black housing material is more sensitive to scratches and welding joints are more visible and rough.
Instruction concerning the turning of the piston rod eye:
When mounting and taking into use, it is not permitted to turn the piston rod eye several times. In cases where the eye is not positioned correctly, the
eye must be screwed to its bottom position (1) and then maximum half a turn outwards again (2).
Mounting bracket instructions:
To avoid damage to the actuator, it is important that the acutator drives to the application endstop position and continues to operate in the groove
until it activates the electric actuator endstop.
To avoid accumulated water inside the quick release lid (see illustration to the right) it is recommended not to mount the LA40 quick release actuator
with the lid in downward position.
