Battery Installation

IMPORTANT: Make sure battery is securely
mounted in the frame. A loose battery may cause
damage to the case resulting in acid leakage and
severe damage to the machine. A hazard may be
created by damage to critical working parts and
safety systems.
Install the battery in the mower as shown in Bat-
tery Installation photo. Connect the positive (+)
first and then the negative (-) cable to the proper
battery terminal [red cable and boot connects to
the Positive (+) terminal]. Slide the rubber boot
up and over the battery post, making sure it covers
the post completely to prevent an electrical
short.
