1.9 Tier 4F Compliance Information

In order to comply with tier 4F emissions regulations, the exhaust system in the

RT-40 is equipped with a Diesel Oxidation Catalyst (DOC) that passively treats the

exhaust gasses as they flow through the system. It does not require operator

intervention of any kind. The emissions system on the RT-40 is designed to be

tier 4F compliant for the life of the machine.

The tier 4F engine and emissions system in the RT-40 requires Ultra Low Sulfur

Diesel (ULSD) fuel to operate properly. There are special considerations regarding

the use and handling of ultra low sulfur diesel fuel. Information on these topics

can be found on the following pages: 18-19 (section 2.10 - Fuel Handling

Precautions) and 34 (section 3.11 - Fluid Specifications).

The RT-40 is also equipped with self-diagnostic features common to modern

diesel engines. Information regarding self-diagnostics can be found on the follow-

ing pages: 37 (section 4.1 -

NOTICE

message), 45-47 (section 4.8.1 - main menu

and active faults - accessing fault information through the operator interface).
