Announcement:
Toro Commercial Tier 4 products were introduced in 2013 due to changes in
Environmental Protection Agency (EPA) emission compliance requirements for
diesel engines.
Understanding the function of the engine’s diesel particulate filter (DPF) and the
regeneration process are important aspects of owning these machines.
When
an engine exhaust DPF (soot filter) becomes restricted, it must be addressed
immediately.
In order to keep these products operating at peak performance levels and to
avoid any “down time”, it is important that customers understand the Tier 4
regeneration process, and the Tier 4 specific maintenance requirements.
We ask that you take a moment to review the material in this bulletin in order to
familiarize yourself with Tier 4 maintenance requirements. Additionally, please
share this information with anyone in your organization who operates or
maintains Toro Tier 4 products. Should you have any questions, contact your
local Toro distributor.
