Your new ram is, for the most part, maintenance free. The handles will begin to feel looser with repeated usage. This is normal as the bearing washers seat over time. If you wish to tighten the handles back up, you will need a 1/4" Allen Key (hex key) amd a 9/16" wrench. Tighten each bolt until handle is satisfactorily taught for your use. Be careful not to over tighten them as damage to the bearings may occur.
