to clean or not clean air filter

[Magicman]

i run a 36'' fan at my back that keeps the dust going away from me when i'm sawing.may be hard for a portable miller to use but it really helps on my stationary setup   pc

  I've had  "headwinds" that actually made me stop sawing.  I try to always set up with my back to the Southwest.  But sometimes the wind will still fool me.  With a strong "headwind", it not only blows sawdust to the air filter, but the engine radiator also catches full.  It'll cause me to run hot if I'm not looking and knock it off of the radiator.   I've even tried to use a generator and fan at my back, but sometimes the wind is stronger than the fan.

I'm using an air conditioner filter across the radiator to keep the sawdust out of the fins.

I am a small engine mechanic and blowing out filters with compressed air is ok if you dont hold it close to the gun.  As for K&N...   If you oil them as you are supposed to they catch all the dirt they need to.  I see guys that dont oil them or install them right have issues.  if sealed up as they are designed to be they work great.  I am too cheap to run them on my bikes..  but my truck has one in it and has no issues.
