This symbol warns of possible personal injury.
These instructions are for your safety and the safety of the end user. Read them carefully until you

General Safety Information
To prevent injury to yourself and/or damage to the equipment:
■
Read carefully all owner’s manuals, service manuals, and/or other instructions.
■
Always follow proper procedures, and use proper tools and safety equipment.
■
Be sure to receive proper training.
■
Never work alone while under a vehicle or while repairing or maintaining equipment.
■
Always use proper components in applications for which they are approved.
■
Be sure to assemble components properly.
■
Never use wornout or damaged components.
■
Always block any raised or moving device that may injure a person working on or under a vehicle.
■
Never operate the controls of the Power Take-Off or other driven equipment from any position that
could result in getting caught in the moving machinery.
Proper Matching of P.T.O.
WARNING: A Power Take-Off must be properly matched to the vehicle transmission and to
the auxiliary equipment being powered. An improperly matched Power Take-Off could cause severe
damage to the vehicle transmission, the auxiliary driveshaft, and/or to the auxiliary equipment being
powered.
Damaged components or equipment could malfunction causing serious personal
injury to the vehicle operator or to others nearby.
To avoid personal injury and/or equipment damage:
■
Always refer to Chelsea catalogs, literature, and owner’s manuals. Follow Chelsea
recommendations when selecting, installing, repairing, or operating a Power Take-Off.
■
Never attempt to use a Power Take-Off not specifically recommended by Chelsea for the vehicle
transmission.
■
Always match the Power Take-Off’s specified output capabilities to the requirements of the
equipment to be powered.
■
Never use a Power Take-Off whose range of speed could exceed the maximum.
Cold Weather Operation of Powershift P.T.O.
WARNING: During extreme cold weather operation [32°F (0°C) and lower], a disengaged
Powershift Power Take-Off can momentarily transmit high torque that will cause unexpected output
shaft rotation. This is caused by the high viscosity of the transmission oil when it is extremely cold. As
slippage occurs between the Power Take-Off clutch plates, the oil will rapidly heat up and the viscous
drag will quickly decrease.
The Power Take-Off output shaft rotation could cause unexpected movement of the driven equipment
resulting in serious personal injury, death, or equipment damage.
To avoid personal injury or equipment damage:
■
Driven equipment must have separate controls.
■
The driven equipment must be left in the disengaged position when not in operation.
■
Do not operate the driven equipment until the vehicle is allowed to warm up.
