GUIDEBAR AND DIAMOND CHAIN INSTALLATION & TENSIONING
CHAIN TOO TIGHT CHAIN TOO LOOSE
STEP 7
Check for proper tension by pulling the chain around the bar by hand.
If you cannot easily pull by hand, the chain is too tight and needs to be
loosened slightly.
CAUTION: Be aware that the guidebar rails may develop sharp edges
over time so always pull the diamond chain by the diamond segments.
STEP 8
Continue to lift up on the nose of the guidebar and firmly tighten the
side cover nuts.
NOTE: To prevent chain tensioner breakage, be sure the side cover
nuts are tightened to approximately 27 Nm (20 ft-lbs).
