Inc.)Service Center forfuse replacement (if so equipped), maintenance
and repairs.

B. BATrERY:

1. Whenservicingbattery, alwaysconnectcablestobatteryexactly
as they were before removal (ground cable to battery negative [-
or neg.] post). If incorrectly connected, altemator won't charge

battery. If this happens, see your Sears Roebuck and Co. (or
Sears Canada, Inc.) Service Center.

2. Never expose engine igniti0n system to battery power. If battery

cable or any live wirecontacts ignitionsystem groundwire, engine
ignition system may be damaged.

3. Ifexternal battery charger is used, disconnect positive (+ or pus.)

cable from batteryto prevent possible damage.

4. See battery manufacturer's instructions for service and storage.

(_) COOLING SYSTEM:

IMPORTANT: Frequently remove any grass clippings, dirt and debris from
