4.1 Technical Maintenance Procedures

Carrying out the technical maintenance specifications of the tractor is the effective way to prolong the service life
of the tractor and reduce accidents.
The technical maintenance schedule for 35XT series tractors is based on the accumulated work hours, which
includes maintenance for: every shift (per 10 work hours), every 50 work hours, every 200 work hours, every 400
work hours，every 800 work hours, every 1600 work hours, and winter and long-term storage.
IMPORTANT ISSUES:
1. All maintenance should be carried out by the owner/operator or a trained service professional who is
familiar with the tractor.
2. In order to make the tractor work properly and to prolong its service life, technical maintenance
procedures must be strictly observed during running-in and normal operation.
3. The tractor warranty can be voided at any time should damage happen as the result of any operator who
is unfamiliar with the tractor or when specified maintenance procedures are not performed according to
manufacturer specified timelines.
4. Opening the engine and hydraulic system safety valve, the relief valve, and the voltage regulator
are prohibited, without prior manufacturer authorization. Making adjustments to these sensitive areas
may cause damage to the tractor, and invalidate the warranty.
