DO NOT

allow the unit to be used as a toy.

maintain the unit.

• Stay alert! Do not operate the unit when tired, ill or under the influence of alcohol, drugs or medication.
• Never allow children to operate the unit. Never allow adults to operate the unit without proper instruction.
• Make sure that all guards and safety attachments are properly installed before operating the unit.
• Keep these instructions. Refer to them often and use them to instruct other users. If loaning

someone this unit, also loan them these instructions.

• Keep bystanders, especially children and pets, at least 50 feet (15 m) away. If anyone enters the

work area, stop the unit!

• Keep the work area clean. Cluttered areas invite injuries. Do not start cutting until the work area is clear

and free from obstructions, there is secure footing and a planned retreat path from falling branches.

• Always wear appropriate eye and ear/hearing protection when operating this unit. Wear safety

goggles, or safety glasses with side shields, that are marked as meeting ANSI Z87.1-1989
standards. Failure to do so could result in serious eye injury caused by thrown or falling objects. If
the operation is dusty, wear a facemask or dust mask. Use a hard hat or other type of safety helmet.

• Dress appropriately, wear heavy, snug-fitting clothes (long pants and a long sleeve shirt), non-slip

protective gloves and steel-toed safety boots. Do not wear loose clothing, jewelry, short pants,
sandals or go barefoot. Secure hair above shoulder level to prevent entanglement in moving parts.

• Only use the unit in daylight or good artificial light.
• Only use the unit for its intended purpose: to cut wood. Only use the unit as described in this

manual. Only use the manufacturer’s recommended attachments with this unit.
