10.1. Preparation of actuator for assembly

Before starting assembly of the actuator, prepare the following material for completion,
equipments and tools.



For fixing onto metal window frames
headed metric screws



For fixing onto wooden window frames



For fixing onto PVC window frames



Equipment and tools: measuring tape, pencil, drill/screwdriver, set of drill heads for
metal, insert for screwing in, electricians pliers, screwdrivers.
