I have had this timer for a few years now and I find the ON OFF tappets very stiff and hard to move to change the settings. Will I damage anything if I spray the timer mechanism

Answer: 
good afternoon , the Danfoss 103 relies on the frictions to keep the tappets in place , if a lubricant is used they may become to loose and may slip failing to push round the pre-selector wheel in the corner.
