Maintaining Fuel Systems for Komatsu Equipment

It is important to understand the fuel system requirements for Komatsu's Tier 4 Interim and Tier 4 Final
machines, including the required fuel types, managing and maintaining the fuel filtration
system, and general best practices to maintain equipment performance. Watch the video from Komatsu below to go over some of the basics.

What is required fuel type for Komatsu Tier 4 Interim and Tier 4 Final Products?

Komatsu Tier 4 interim and Tier 4 final machines utilize ultra-low sulfur diesel.

What are some best practices for maintaining my fuel system?

• Park on level ground. This ensures accurate fuel readings during next pre-inspection.
• Refill at the end of a shift when machine is still warm. This reduces condensation in the tank which can go a long way towards keeping contamination levels lower in the fuel system.
• Check the prefilter for contamination on a daily basis as part of the pre-operation inspection. If there is contamination in the sediment bowl, open the valve on the bottom, and drain the contents into a catch can. Make sure the engine is off before draining the contents.
