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 40XT and 50XT 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.
4.1.1 Technical Maintenance for Every Shift (every 10 hours)
1. Remove the dust, oil and dirt from the tractor, and clean the air filter if working in dusty conditions.
2. Check and tighten (if necessary) each fastener outside the tractor, especially the fastening nut for the front and
rear wheels.
3. Check the level of the engine oil pan, radiator, fuel tank, hydraulic steering oil tank and hydraulic lifter and
battery. Refill if necessary. Before checking the oil level of engine oil pan, the tractor should be parked on a flat
surface and the engine cool.
4. Fill lubricating grease according to Maintenance Table 4-1.
5. Check the tire pressure and refill as needed.
6. Check if the tractor has any air, oil or water leakage. If any leakage is found, have it repaired immediately.
