MAINTENANCE
OPPORTUNITY CHARGING (OPTION)
NOTE: The machine must be equipped with
a TPPL battery or a battery capable of being
opportunity charged. Do not opportunity charge
standard batteries since doing so can shorten
battery life.
Opportunity charging is used to extend machine
run time and productivity by allowing batteries to
be charged during breaks, lunch, between shifts,
or whenever there is an “opportunity” to charge.
Opportunity charging (i.e. partial charge cycle
of a half hour or more) is only recommended if
discharge level is below 80% (i.e. when discharge
indicator is at or beyond second green light).
IMPORTANT: Before charging, make sure that
the machine and charger settings are properly
set for the battery type.
