month. Do not store the battery in an exces-
sively cold or warm place [less than 0 ° C (30
° F) or more than 30 ° C (90 °F)]. For more in-
formation on storing the battery, see page

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.U1BS62E0.book Page 5 Monday, April 18, 2011 6:43 PM
