Proper Idling
What’s Regeneration in Tier 4 Machines?
- Newer machines have filters that catch soot produced by the engine
- These filters have self-cleaning abilities called regeneration
- Regeneration uses heat to oxidize soot into gases that leave the filter
- It’s a normal part of running machines equipped with diesel particulate filters and rarely gets in the way of operating
![]() When you see this yellow symbol:• Work your machine hard○ A loaded engine makes hotter exhaust gas, and that’s better for regeneration • If you need to shut the machine down, that’s fine ○ Regeneration will pick up where it left off at the next restart • If you need to idle, do it the right way |
![]() When you see this red symbol:• Park the machine in a safe area• Follow proper idling procedure |
How To Properly Idle & Shut Down
- If you’re going to idle for more than a minute or two
○ In a tracked machine, all lock levers in the lock position and throttle dial at minimum
○ In a wheeled machine, transmission in neutral, parking brake applied and accelerator pedal released - This is the safest way
- It also helps the machine optimize regeneration
- If you’re going to shut down, let the machine cool off for 5 minutes before turning the key
