WARNING

To reduce the risk of personal injury from unintended
activation or unauthorized use, shut off the engine and
engage the chain brake before transporting the chain saw or
putting it down. To reduce the risk of injuries from the sharp
cutters on the chain, always cover the guide bar with the
chain scabbard before transporting or storing the saw.
To prepare the saw for transportation or storage:
► Shut off the engine, @ 15.
► Release the chain brake and loosen the chain, @ 12.2.
► Re-engage the chain brake.
► Slide a chain scabbard over the guide bar so that it covers
the entire guide bar.
► Before using the saw, remember to re-tension the chain.
NOTICE
The chain contracts as it cools down. Failing to loosen the
chain after finishing work can damage the drive shaft and
bearings.
