Situation Important Information
Proper battery replacement and battery cable routing are critical to the safe
and reliable performance of Toro Commercial products. Varying from the
recommended battery and electrical system maintenance published in both
the machine Operator's Manual and Service Manual, could cause machine
downtime or even serious damage.
Over time, repair actions such as battery removal or replacement have
deviated from the Operator’s Manual and Service Manual information,
which could result in battery cable exposure. If the B+ (Positive) battery
cable becomes loose or repositioned, it may lead to contact abrasion, and
the potential for conductor corrosion or a short to ground that could lead
to other potential damage.
Corrective Action Inspect
Important: Incorrect battery cable routing could damage the machine
and cables causing sparks. Sparks can cause the battery gasses to
explode, resulting in personal injury.
1. Inspect the battery to ensure that the correct BCI Group 24 is installed.
Refer to the Parts Catalog for the machine.
Important: Batteries that do not meet the correct BCI specification
should be replaced with the correct battery.
2. Ensure that the battery terminals align toward the front of the machine.
