I have a single story one like the one you show. I also found this to be the best way to clean also. As I live in the north sun/heat is not a problem. Most of out plant go outside in the spring . Heat is more of a problem.
Hello . Not a Blackhawk guy but came across one on craigslist in Wausau Wisc. if anyone is interested. Model 84 6000 lb. Has a S/n if you would like me to get it.
turning to the left will open air inlet to max power. Like the other guys have said a few drops of oil is great for sure. I like to do the same if I can at the end of the day put a few drops in . A short run of the tool .
Both guys hit it right for sure. My suggestion to people has been if you can at the end of the day run some oil through the tools. Helps rinse the junk out keep lubed until the next use.
Checked my spec. charts. Tool is the same as the old CP 732 and the Central pneumatic 1/2 inch
250 lbs max. 3/8 air line 125 psi.
I test repaired tools on a Skidmore Mod. ML I/2 tools tested on 5/8 bolt.
Hope this helps
Drill still going strong. Using in the shop. 3/4 cap. can change to # 3 Morse taper. The other container is Misc. Old Thor and Cp grinders. The drill is one that was made in the plant in Aurora Ill.
