OIL REPLACEMENT
When engine is new, replace oil after
the 8 first hours of operation. Then,
replace depending on the intensity of
work (from 30 to 50 hours maximum).
Always check oil level when using the
machine and refill whatever amount may
be missing (page 33)
Oil replacement must be done when the
engine is slightly hot, so that the
crancase is cleaned more efficiently.
1st Remove draining cap (Fig. 11)
2nd Drain used oil completely
3rd Place the oil draining cap again
4th Remove the filling oil cap
5th Pour new oil into the oil filling hole until reaching adequate level
6th Place the oil cap again
Never use the machine without ensuring that oil level is adequate.
Otherwise, the engine will wear quickly.
NOTE: However many oil replacements you make, you are not losing money as the
working life of the machine will be greater, thus saving money.
