Toro Groundsmaster 7210, Service Manual

Page: 43 / 342

The engine that powers your Groundsmaster 7210 machine is a Yanmar model
3TNV88C with EPA Tier 4F emission regulations. The engine is equipped
with an exhaust system that includes a diesel oxidation catalyst (DOC) and a
diesel-particulate filter (DPF).
These exhaust components require service or component replacement at regular
intervals, refer to the
Operator’s Manual .
At recommended intervals, DPF reconditioning is necessary which will require
exhaust system disassembly, DPF removal, and DPF reconditioning that is done
by a company that has necessary equipment. Once the DPF has gone through
the reconditioning process, it can be re-installed in the exhaust system. Contact
your Toro Distributor for information on reconditioning the DPF.
The diesel oxidation catalyst (DOC) has a service life expectancy and requires
replacement at recommended intervals. Replacement of the DOC will require
exhaust system disassembly, removal of the existing DOC and installation
of the new DOC.
Additional information about the diesel-particulate filter (DPF) operation and
maintenance can be found in the Yanmar Service Manual and the Yanmar
Troubleshooting Manual.

CAUTION
A hot engine and exhaust system can cause burns.
Allow the engine and the exhaust system to cool before working
on or near them.

engine, set the parking brake, and remove the key from the key switch.
