Introduction

The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.

Problem

There have been isolated instances of diesel particulate filter regeneration intervals being reduced.

Solution

Ensure that the correct specification of fuel is being used. Refer to Operation and Maintenance Manual, "Fluid Recommendations" for more information.

Improvements to the deterioration in diesel particulate filter regeneration intervals can be achieved by cleaning of the fuel system.

Use 343-6210 Cleaner . If 343-6210 Cleaner is not available, use 256-4968 Cleaner as an alternative.
