IMPCO Idle Limiter Start & Stop

IMPCO Idle Limiter Start Stop
"Reduce Idling, Save Fuel"

The IMPCO Idle Limiter (IIL) was designed for internal combustion engine Forklift Trucks which automatically cuts the truck out after a pre-set period of time.

The microprocessor based control system is designed to save you money on excess fuel expenditure. It’s also a very important Health & Safety device as it will turn off trucks automatically that have been left running when unattended. The IIL achieves this by cutting the truck out after a pre-set period of time if the seat is left unoccupied or if the driver is sitting there with the engine idling. 


  • Improve site safety
  • Save money on fuel
  • Protect against excessive engine wear
  • Reduce engine hours
  • Reduce hire costs

The IIL system can look at two parameters, the seat switch if a truck has one fitted or an RPM signal that can be found on the negative side of the ignition coil in case of a LPG truck and on the alternator if a “W” terminal is available on diesel trucks. The system is designed to have both options working at the same time or one or the other.

The time out function is adjustable and can be set between 30 seconds and 5 minutes with 1 minute increments. We have a 12 and 24V unit available both versions are supplied as a professional kit with full installation instructions and everything necessary to install the system.
