2. If the battery will be stored for
more than two months, check the
specific gravity of the electrolyte
at least once a month and fully
charge the battery whenever nec-
essary.
3. Fully charge the battery before in-
stallation. NOTICE: When install-
ing the battery, be sure the key
is turned to “OFF”, then connect

4. After installation, make sure that
the battery leads are properly con-
nected to the battery terminals
and that the breather hose is prop-
erly routed, in good condition, and
not obstructed. NOTICE: If the
breather hose is positioned in
such a way that the frame is ex-
posed to electrolyte or gas ex-
pelled from the battery, the
frame could suffer structural
and external damages.

If a fuse for the individual circuits is
blown, replace it as follows.
1. Turn the key to “OFF” and turn off
the electrical circuit in question.
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage. WARNING! Do not
use a fuse of a higher amperage
rating than recommended to
avoid causing extensive dam-
age to the electrical system and
possibly a fire.
