NOTICEECB00120
Do not use accessories requiring more than
the above maximum capacity. This may
overload the circuit and cause the fuse to
blow.
If accessories are used without the engine
running or with the headlights turned on, the
battery will lose its charge and engine start-
ing may become difficult.
Do not use an automotive cigarette lighter or
other accessories with a plug that gets hot
because the jack can be damaged.Maximum rated capacity for the auxiliary DC
jack:DC 12 V, 10 A (120 W)

The figures quoted are emission levels and are not
necessarily safe working levels. Whilst there is a
correlation between the emission and exposure
levels, this cannot be used reliably to determine
whether or not further precautions are required.
Factors that influence the actual level of exposure
of work-force include the characteristics of the
work room, the other sources of noise, etc. i.e. the
number of machines and other adjacent process-
es, and the length of time for which an operator is
exposed to the noise. Also the permissible expo-
sure level can vary from country. This information,
however, will enable the user of the machine to
make a better evaluation of the hazard and risk.
