IR 2135-k303 air inlet repair kit along with a 2131-322 air inlet removal tool should get it repaired.

Look in the yellow pages for power tool repair. Or go online to Ingersoll-Rand's page

The air motor on the 285B needs to be oiled, the hammer section needs to be greased. The symptom described could be in the hammer mechanism, 285B's have 2 different side plates (item# 41) that sit atop the hammer mechanism, tools made from 2005 to 2007 use the old style side plate (item# 41) that has a small lip that need to sit looking toward the hammer case bushing (item# 44) when installed with the small lip facing in to the hammer will cause it to lock, tools made from 2008 to the present have a side plate that is flat on both sides and can be installed in either position. also check the hammer and anvil for cracks and pitting.

There is the breakdown for your tool. I hope this helps.

This gun shouldnt have an adjustment. If you cfm's from your compressor are enough. Too low cfm's mean lower torque. If cfm is high enough for the gun rating then I would say the gun is bad.

that tool is under warrenty whoever u bought it from should have it fixed. did u try to adjust the air flow on your forard and reverse by turning the nob right or left has numbers on it hold the trigger turn the nob i see what it does i rebuilt many a 261
