This cancause wheel fragments to eject at veryhigh rates of maintain proper grinding wheelmaintenance, check for visible cracksand perform a ring test.

2 (A goodgrinding wheel will sound a clear musicaltone when tapped gently with a metal toollike an Allen wrench.) See Fig 8, page not force a grinding wheel onto themachine or alter the size of the mountinghole. Do not use a wheel that does not fitexactly. We recommend use of Oregon grinding wheels sure the mounting-flange nut isserviceable and not damaged in any grinding wheel vibration should occurwhen the grinder is started, or running,remove and inspect the mounting flangeand the grinding avoid possible grinding-wheel failure,always allow a new grinding wheel to runat operating speed for at least one minutebefore grinding or hazard of kickback resulting in seriousinjury to operator is increased if cuttingchain guard drive links or guard tie strapshave been reversed, removed, or fileddown.

3 To avoid injury Do not use a cuttingchain that has been altered in any chain depth gauges not properlyfiled can substantially increase the risk ofkickback and injury. To reduce likelihoodof injury, always file depth gauges to original the grinding wheel places thefingers of the operator in close proximityto the grinding wheel.
