Carry out the procedure of installing or removing saw chain in a clean place
free from sawdust and the like. Do not tighten the saw chain too much. Excessively high
tension of saw chain may cause breakage of saw chain, wear of the guide bar and break-
age of the adjusting dial. A chain which is too loose can jump off the bar and it may cause
an injury accident.
2. Turn the tension knob clockwise to tighten the saw chain until the lower side of the
saw chain fits in the guide bar rail as illustrated.
Make sure that the saw chain does not loosen at the lower side and the
saw chain fits snugly against the lower side of the bar.
