Step 6: Bar Tip Clearance On sprocket nose bars, check for clearance around the bar tip between top of rails and the bottom of cutters or tie straps weekly. Replace nose sprockets before cutters or tie straps contact the bar rails.        Chainsaw Guide Bar Clearance


Step 7: Chain Lean With chain on the bar, hold a straightedge against the bar body and against a cutter side plate. A good groove will hold the chain straight, leaving a small gap between the straight edge and bar body. A worn groove will let the chain lean until straightedge is flush with bar body. Replace bar if groove is worn. Check weekly.    Chainsaw Guidebar Lean
