DEUTA FAHR Tractor AGROCOMPACT Workshop Service Manual

introduction This publication is intended for the trained technician who must operate on our tractors. It contains all general information relating to our tractor range, and in particular it highlights the inspection, overhauling and adjustment procedures as well as the main instructions for dismantling and reassembling operations. The workshop manual is a natural summary for the mechanic who has attended the vocational training and specializa- tion courses, which are held every year at our Service School, to permit him to perform a precise and qualified work on tractor. Its contents are therefore an exhaustive reference book for the experienced mechanic who desires to refresh his me- mory on the sequence of the operations to be done. It is then good practice for every authorized dealer mechanic to have at his disposal this publication, so that it may be consulted quickly when necessary. We wish to thank in advance for the cooperation all thos people, who will let us have their suggestions in order to make this publication more complete. 1 WORKSHOP MANUAL

Intervals between oil changes: every 250 operating hours for lubricants with API-CC specifications every 500 operating hours for lubricants API-CD, API-CE, API-CF-4, CCMC-D4 specifications (see following note). N.B. - Oil change intervals should be halved when: the operating temperature is <10°C (+14°F) the fuel contains more than 0.5% of sulphur “Bio-diesel” fuel is used IMPORTANT: the oil must be changedat least once a year, regardless of the number of operating hours completed. It is advisable to always use the same type of oil when replenishing. 10
