Basic Safety Precautions

nDo not operate a chain saw with one hand! Use a firm grip with thumbs and fingers encircling the chain saw handles. Serious injury to the operator, helpers, bystanders, or any combination of these persons may result from one-handed operation. A chain saw is intended for two-handed use.

nAlways be aware of what you are doing when using the chain saw. Use common sense. Do not operate the chain saw when you are tired, ill, or under the influence of al- cohol, drugs, or medication.

nStay alert and pay attention to what you are doing. Use common sense when using this unit.

nKeep all parts of your body away from the saw chain when the unit is running.

nAlways carry the chain saw by the front handle with the unit stopped and the guide bar and saw chain positioned to the rear. When transporting your chain saw, use the appropriate guide bar scabbard.

nNever let anyone use your chain saw who has not received adequate instructions in its proper use. This applies to rentals as well as privately owned saws.

nBefore you start the unit, make sure the saw chain is not contacting any object.

nStop the chain saw before setting it down. Do not leave the unit running unattended.

nTo avoid accidental starting, never carry the unit with your finger on the trigger.

nMaintain the unit with care. Keep the cutting edge sharp and clean for best performance and to reduce the risk of injury. Follow instructions for lubricating and changing accessories. Inspect the battery charger cord periodi- cally, and if damaged, have it replaced or repaired by an authorized service dealer.

nKeep handles dry, clean, and free of oil and grease.

nDo not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Chain should stop turning when the trigger is released. If the chain turns after the trigger has been released, have the unit serviced by your nearest Ryobi service dealer.

nCheck for damaged parts. Any part or guard that has been damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other condi- tions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service dealer unless otherwise indicated elsewhere in this manual.

nAll chain saw service, other than the items listed in the operation and maintenance sections, should be performed by your nearest Ryobi service dealer.

nDo not use in the rain, snow or wet conditions.

nAlways maintain a proper stance. Do not overreach.

nDo not adapt your powerhead to a bow guide or use it to power any attachments or devices not listed for the saw.

nDo not cut vines and/or small underbrush.
