Just got to make sure we service them every 200 hours.
Thanks everyone for your input.
This service should not only be based on hours but also on age/time. They also corrode and corrosion is a function of time. 200 hours also seems a bit aggressive. That would be less than a year for me and for commercial guys that would be many times a year. I do mine every 3 years and they are fine. And that equates to about 700 hours. Nothing wrong with doing them more often but it just seems like a bit much.
