5. Service and maintenance
5.1 General
Regularly perform occular control of the PC-Series unit and the installation it is a part of and service and
repair if needed. If in doubt, please contact Thomson for advice.
5.2 Cleaning
The PC-Series actuators are designed to withstand water wash down. If the actuator needs to be
cleaned, clean it gently and do not use any tools that mechanically can damage the actuator. If
detergents are to be used during cleaning it is recommended to stay within pH 3.5 – 8.5.
5.3 Lubrication
Lubrication is needed after 600 hours of operation or 6 months depending on which happens first.
Perform lubrication as described below.
1. Make sure the extension tube is fully retracted to the mechanical end position. Retraction to the
mechanical end position may only be done if the actuator is unloaded and the retraction motion may not
exceed the maximum torque and speed listed in table T5.3.1. Failing to do so may damage the actuator.
Once in the mechanical end position the retraction must be stopped immediately.
2. Lubricate via the grease port (1) with a grease gun (nipple type DIN3405 D1/A) using a grease of type
Urethyn E/M1 (semi-synthetic, high temperature grease containing an organic thickener) with the amount
listed in T5.3.2.
