ADJUST THE CHAIN TENSION
The more you use a chain the longer it becomes. It is
therefore important to adjust the chain regularly to take up the
slack.
Tension the chain so that it can only just be pulled away from
the bar at its center point.
A slack chain may jump off and cause serious or even fatal
injury.
Wear protective gloves if you touch the chain, bar or areas
around the chain.
