Installing Tray and Battery
To obtain electric start, you must purchase and install a
12 Volt DC battery (Series U1–109). The battery should
be serviced as necessary and fully charged prior to
installation. Install the battery as follows:
• Find the battery tray and fasteners shipped loose in the
carton. You should have one battery hold down bracket,
a black battery cable, a red battery cable, two 7" J bolts,
two lock washers, two flat washers and two hex nuts.
• Remove the four battery tray screws from cradle.
• Position the battery tray and install with screws removed
above (Figure 3).
