Awhile ago, I blogged about finally changing the oil on my planer. Oh, my, that stuff was treacle not oil! I want a way to track my planer's hours so I can plan to change the oil after 35 hours of use, but how?! Many tools could use metering. I could see any industrial tools like this PM-20 planer having oil that needs changing or maybe put a timer on a DC unit to know when to rince the canister filter. Or maybe just out of curiosity like an odometer; might be interesting for shop owners wanting to know what gets used and for how long.
Now all I need is to 'borrow' an oil-change sticker next time I get my car done so I can mark my planer as due at 35 hours of run-time.
