3.2.2 Check the voltage of the battery with a digital voltmeter. Locate the voltage reading of
the battery in the table below and charge the battery for the recommended time
interval to bring the charge up to a full charge of 12.6 volts or greater.
IMPORTANT: Make sure the negative battery cables are disconnected and the
battery charger used for charging the battery has an output of 16 volts and 7
amps or less to avoid damaging the battery (see chart below for recommended
charger settings).

CAUTION
POTENTIAL HAZARD
If the ignition is in the “ON” position there is potential
for sparks and engagement of components.

3.2.3 Connect the negative battery cables.
NOTE: If the positive cable is also disconnected, connect the positive (red)
cable to the positive battery terminal first, then the negative (black) cable and
green/white wire to the negative battery terminal. Slip insulator boot over the
positive terminal.
NOTE: If time does not permit charging the battery, or if charging equipment is
not available, connect the negative battery cables and run the vehicle
continuously for 20 to 30 minutes to sufficiently charge the battery.
3.3 INSTALL DRIVE WHEELS.
3.3.1 Mount drive wheels with the valve stem to the outside of the unit. Secure using
four (4) 1/2-20 wheel nuts (installed on studs in hubs) for each wheel. Torque to
95 ft-lbs (128 NxM).
3.4 CHECK TIRE PRESSURE.
3.4.1 Check tire pressure in caster and drive tires. Proper inflation pressure for caster
tires is 16 psi (110 kPa). Proper inflation for drive tires is 13 psi (90 kPa). Adjust
if necessary.
