Sanborn Back Max oil capacity, type and grade
by John L
(NC high country)
recently inherited Sanborn Back Max, 5hp, two stage, 80 gal compressor. Can only read first three and last two of model number -
B51???24, no manuals. Unit is all black in color with large chrome label stating "Sanborn manufacturing Co" and ph# for product asst (not working). Been sitting for about 4 years inside garage. Ready to wire 220v and try to operate but want to change compressor oil. Don't know how much and what kind to replace it with. Would love to have manuals, but at least help with info about oil capacity and type/grade. Thanks much for any help.
