General Information
Cold Weather Operation of PowerShift PTO
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.
Rotating Auxiliary Driveshafts
WARNING:
■
Rotating auxiliary driveshafts are dangerous. You can snag clothes, skin, hair,
hands, etc. This can cause serious injury or death.
■
Do not go under the vehicle when the engine is running.
■
Do not work on or near an exposed shaft when the engine is running.
■
Shut off the engine before working on the Power Take-Off or driven
equipment.
■
Exposed rotating driveshafts must be guarded.
Guarding Auxiliary Driveshafts
WARNING: We strongly recommend that a Power Take-Off and a directly
mounted pump be used to eliminate the auxiliary driveshaft whenever possible.
If an auxiliary driveshaft is used and remains exposed after installation, it is the
responsibility of the vehicle designer and PTO installer to install a guard.
