Common operating procedures

This section explains procedures for starting the engine, arriving at the job site, and leaving the
job site.
3.6.1 Engaging the power take-off
Engaging the power take-off (PTO) activates the hydraulic pump, which supplies power to the
controls. When the PTO is engaged, a warning light in the cab warns you that driving the vehicle
may result in damage. Before driving the wrecker, ensure that the warning light is off and the
PTO is disengaged.
The following is a general procedure for a manual transmission. An automated transmission or
fully automatic transmission might require a different sequence to engage properly. Refer to the
transmission and PTO operation manuals specific to your vehicle.
Turn off the wrecker engine and disengage the PTO when the wrecker is not in use.
The area under the lifting unit is DANGEROUS. Stay as far away as possible from
the danger zone while the machine is operating.
To engage the PTO:
1. Check that none of the emergency stop buttons have been pressed and pull them, if
necessary.
2. Ensure that the PTO is disengaged.
3. Start the truck engine.
4. Ensure that air pressure is above 70 psi before engaging the PTO.
5. Press the clutch, engage the PTO and release the clutch to start the hydraulic system.
The hydraulic system supplies power to the boom, underlift, winch, etc.
The control panels automatically turn ON when you engage the PTO.
