4.1.4Check safety interlock system.

Service Interval: Daily

a)For your safety, your Exmark mower is equipped with Operator Presence Controls, referred to as (OPC). When either the PTO is engaged, or the transmission shifter lever is not in neutral and the operator removes both hands from the handles, the mower engine MUST stop.

b)To determine if the OPC is in operating condition, clear area of bystanders. Run the engine at one-third throttle, then with the drive levers and neutral lock latches in the “park brake” position, shift the transmission into gear and release the OPC levers – the engine MUST stop.
