My maintenance on equipment is pretty much the same as everyone else who has posted here. There isn't to much I haven't done over the years. My problem is that as every year goes by I lose my desire to get motovated to do it. I've spent too many hours, nights and weekends working on saws, trucks and other equipment getting greasy from head to toe, getting doused in oil and antifreeze, ruining good work cloths, fighting other peoples bad maintenance and cheap fixes. I used to enjoy it, but now I would rather hire it out or find some one like Murph has.
One thing I didn't see mentioned when it comes to saw fixing,, after you blow off the coarse stuff, any one spray their saws down with a mild degreaser like Simple Green, helps to loosen that caked on set in oil and grime, after that I spray them down with carb cleaner for like a final cleaning, after I reassemble the saws I spray the bodies down with carb spray and the blow that off. The carb spray not only cleans but also acts like a dryer to get rid of all that oily film the compressor leaves behind.
As far as I'm concerned working on your own equipment is almost a must do if you cannot afford the luxury of a good mechanic, trouble is these are hours you don't really get paid for, but in some way I feel should be figured into your overhead. There is as much time and effort going on behind the scenes to do maintenance that keeps equipment in good working order that the customer just doesn't see. Unfortunately not everyone in the business shares this view, other wise they would be charging more, instead of less than what we do.
