How To Perform An M-Tronic Reset ;

Many of the M-Tronic machines can be reset to standard factory settings by following the steps below:

1. Put the machine in the Cold start position
2.Start the machine and run it in the Cold start position for at least 90 seconds
3. Do not touch the throttle or accelerate the saw during this time
4. After 90 seconds, switch off the machine
5. Your machine is now re-calibrated and ready for operation

For newer M-Tronic machines (such as the MS462 chainsaw) the process is different so check your Owners’ Manual to make sure that you are following the right procedure. The procedure for newer models is listed below:

1.Ensure the chain brake is engaged (on)
2.Put the machine in the Cold start position
3.Start the machine and run it in the Cold start position for at least 30 seconds but no more than 60 seconds (the period marked as A in the diagram below)
4.Do not touch the throttle or accelerate the saw during this time
5.Disengage/release the chain brake
6.Open / squeeze the throttle fully for at least 30 seconds (B in the diagram)
7.Engine speed varies noticeably during calibration
8.As soon as the engine speed drops noticeably (C), release the throttle back to the idle position
9.When the engine is back to idle speed, engage the chain brake and switch off
10.Your saw is calibrated and ready for operation
