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 the 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.
