8. If chain is too loose, it will sag below the guide bar. DO NOT operate the saw if the chain is loose. NOTE: The chain is tensioned correctly when the weight of the chain does not cause it to sag below the guide bar (with the chain saw sitting in an upright position), but the chain still moves freely around the guide bar. WARNING: If the saw is operated with a loose chain, the chain could jump off the guide bar and result in serious injury to the operator and/or damage the chain making it un- usable. If the chain jumps off the guide bar, inspect each drive link for damage. Damaged chain must be repaired or replaced.
