CHECKING & ADJUSTING CHAIN TENSION
Unpacking & Assembly
All chains have a tendency to stretch when used. Diamond chains stretch more than
wood cutting chains because of the abrasive materials they are cutting. Chain
tension requirements for concrete cutting power cutters is different than wood
cutting chain saws because water is used instead of oil as a lubricant. Refer to
chain tensioning instructions.
A tight chain will reduce cutting power and increase chain friction, resulting in
premature wear of the cutting system. If the tension is set too loose, the chain
could be thrown off of the bar or allow the sprocket to turn without turning the
chain which will damage the drive links.
When a chain stretches to a point where the drive links are hanging approximately
1/2 in (12 mm) to 3/4 in (18 mm) below the guidebar groove, it is time to tension the chain.
IMPORTANT
WARNING
Improper chain tension can lead to breakage of the chain or derailing of the chain
off of the guidebar.
Check chain tension frequently.
