• If the power takeoff will be operated while the vehicle is stopped, set the
parking brake, shift the transmission to
N
(Neutral), and depress the
accelerator as required. Disengage the PTO after returning the engine speed to
idle and stopping the PTO-driven equipment.
• If the power takeoff will be operated while the vehicle is moving, simply
select the desired range and depress the accelerator as required. However, the
speed of the power takeoff during this type of operation will be affected by the
ranges selected and the speed of the vehicle.
• To disengage the power takeoff, stop the vehicle, idle the engine, and set the
brake. Place the shift selector in a drive range, stop the PTO-driven
equipment, and disengage the power takeoff. Return the transmission shift
selector to
N
(Neutral).
CAUTION:
Never engage the PTO by clashing the gear teeth. This
may damage the PTO unit and the PTO drive gear teeth. Stop clash-
ing by releasing the vehicle brakes and allowing the vehicle to
move slightly or by moving the shift selector from a drive range to
N
(Neutral) and back to a drive range.
CAUTION:
Do not exceed the speed limits imposed on the driven
equipment during operation of the PTO.
