POWER TAKE-OFF (PTO) OPERATION

If the vehicle is equipped with a Power Take-Off (PTO) unit, be sure to read
the following section.

PTO Precautions

DANGER
Power Take-Off (PTO) units and related equipment can be very dangerous. Any
PTO installation, repair or replacement should include a warning indicator light
which indicates PTO engagement. The light must be located close to the PTO
control and clearly visible to the operator.
DANGER
PTO units are driven by engine or drivetrain components (flywheel, crankshaft,
transmission). Do not attempt to service the PTO and related units unless the
engine is shut down.
DANGER
Always keep body parts and loose-fitting clothing out of the range of drivetrain
components, or personal injury may result.
DANGER
Always be aware of the current PTO status (engaged or disengaged) and the
position of the vehicle body (dump body controlled by PTO, etc.). Be sure to
disengage the PTO when not in use.
DANGER
On an MP7 engine equipped with Front Engine Power Take-Off (FEPTO), the
torque limit is 385 N.m (284 lb-ft).
