DAVINO 120TW - USER AND MAINTENANCE MANUAL Rev.04
- Pag. 84
Maintenance operation deadlines as reported in this chapter are meant for machines that are run under normal
operating conditions.
During machine “Breaking-In” or under particular conditions these deadlines may vary accordingly.
Specially, when working in a dusty construction site check following points:
- Clean the fins of the radiator more often and make sure that no fin appears clogged;
- Clean the air filter more frequently;
- Replace the fuel filter more frequently;
- Clean the electrical components, especially the starter motor and alternator to avoid dust;
- Move the machine to a location free of dust when controlling and replacing oil or filters.
Lubrication is fundamental for preventive maintenance, as machine life highly depends on it. Therefore, it
is extremely important to follow the instructions outlined in this manual both as to the lubricant usage and
as maintenance operation terms.
Oil for engine and hydraulic equipment deteriorates with use; although it is not dirty, replace always
expected service intervals.
Use only the recommended oil, and never mix oil brands and different grades.
Be careful when handling oil, to prevent impurities from dirt (water, metal particles, dirt). Impurities in the
oil can cause problems on machine functions.
Before and after lubrication, clean any covers, lubricating points and caps to avoid particles from entering.
Always add suggested amount of oil. An excessive or insufficient amount of oil can cause a malfunction.
When changing the oil, always replace respective filter at the same time.
The filters are extremely important parts that prevent possible problems due to impurities.
Never attempt to clean a filter and reuse it; always replace with new filters
Avoid environmental pollution. National and international laws classify
lubricants, fluids, coolants and impregnated filters as harmful and
polluting waste. Storage and disposal thereof is provided for by ad hoc
facilities.
It is recommended to use original spare parts.
Omit this warning may cause premature failure or damage to the
machine.
European regulations (ISO 8331 and EN982 (CEN)) establish that service life of any hydraulic hose may not
exceed 6 years.
It is advisable in any case to replace hoses of hydrostatic transmission (branches A and B) every 2 years.
Always replace pipes that exceeded permitted duration in service, regardless of the outside appearance /
use
If the machine is used at temperatures below 0 ° C, it is necessary to use oils and fuels suitable for such
temperatures, even if ambient temperature can increase during the course of the day.
If the machine is used at temperatures below -20 °C, it is necessary to
equip machine with optional components.
Should this be the case, contact immediately your nearest AUTHORIZED
AMOG WORKSHOP.
