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
