To minimize wear and damage to chain components and the guide bar, proper chain tension must be maintained

Chain tension should be tight enough that cutter bottoms are pulled firmly against the guide bar at all points around the perimeter of the bar

NOTE! Chain tension should be checked in the morning before shift

NOTE! Chain tension will change with heat. Any chain that is uncomfortably hot to the touch should be allowed to cool before re-tensioning

Chain tension tested by pulling the chain with thumb and forefinger at mid bar away from the bar

Chain tension adjusted if incorrect

Chain installed with the teeth properly oriented. The chain rotates from the bottom to the top of the bar in a clockwise direction as viewed in illustration. The sharpened edge of the cutting teeth must be positioned as illustrated
