Battery Storage

Whenever the battery will be stored for an extended period of time, be sure the cells are full of water and the battery is fully
charged and in good operating condition. It should be clean and free of leaks. Follow the battery manufacturer's instructions for
storage.

Recommissioning the Power Package

1. Ensure that all cooling system hoses are connected properly and hose clamps are tight.
Disconnecting or connecting the battery cables in the incorrect order can cause injury from electrical shock or can damage
the electrical system. Always disconnect the negative (‑) battery cable first and connect it last.
2. Install a fully charged battery. Clean the battery cable clamps and terminals and reconnect cables. Tighten each cable
clamp securely when connecting.
3. Coat the terminal connections with a battery terminal anticorrosion agent.
4. Perform all the checks in the before starting column of the Operation Chart.
Without sufficient cooling water, the engine, the water pump, and other components will overheat and suffer damage. Provide
a sufficient supply of water to the water inlets during operation.
5. Start the engine and closely observe instrumentation to ensure that all systems are functioning correctly.
6. Carefully inspect the engine for fuel, oil, fluid, water and exhaust leaks.
7. Inspect the steering system, shift and throttle control for proper operation.
