SECTION 3 - MACHINE CONTROLS, INDICATORS AND OPERATION
To Charge Batteries
1. Park machine in a well ventilated area near an AC volt-
age electrical outlet.
2. Always use a
grounded AC outlet.
Connect charger to
an outlet that has
been properly
installed and
grounded in accor-
dance with all local
codes and ordi-
nances. A grounded
outlet is required to
reduce risk of elec-
tric shock – do not
use ground adapt-
ers or modify plug.
When using an
extension cord,
avoid excessive volt-
age drops by using a
grounded 3-wire 12
AWG cord.

Battery Charging Status Indicators
The battery charging status indicators are located just above the
Charger AC input receptacle on the center cover section at the
rear of the machine. (See Figure 3-1. on page 3-8)
1. When plugged in the charger will automatically turn
on and run through a short LED indicator self-test (all
LED's will flash in an up-down sequence for two sec-
onds).
2. The YELLOW 'CHARGING' LED will turn on and a trickle
current will be applied until a minimum voltage is
reached.
Once a minimum battery voltage of 2 volts per cell is
detected, the charger will enter the bulk charging con-
stant-current stage and the YELLOW 'CHARGING' LED
will remain on. The length of charge time will vary by
how large and how depleted the battery pack is, the
input voltage (the higher, the better), and ambient
temperatures (the lower, the better). If the input AC
voltage is low (below 104VAC), then the charging
