Linear Actuator LA25 | 6 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. • Only use the actuator within the specified working limits. • Do not step on or kick 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. • When mounting the actuator 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. • Prevent impact or blows, or any other form of stress to the housing. • Ensure that the cable cover is mounted correctly. Use 3.5 Nm torque. • Ensure that the duty cycle and the usage temperatures for LA25 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.
