NOTICE
Always use diesel oil for the fuel.
To ensure good fuel consumption characteristics and exhaust gas characteristics, the engine mounted on
this machine uses an electronically controlled high-pressure fuel injection device. This device requires
high precision parts and lubrication, so if low viscosity fuel with low lubricating ability is used, the durabil-
ity may drop markedly.
