To remove the accumulator body to change the diaphragm on a Furukawa F4 breaker:

1. Relieve gas from the accumulator: The accumulator is under high pressure with nitrogen gas. Before removal, release the gas completely to prevent parts from blowing off and causing injury.

2. Use only nitrogen gas: When recharging after diaphragm replacement, use nitrogen gas only. Other gases can cause explosions.

3. Handle with care: Because of the pressure, handle the accumulator and nitrogen gas cylinders carefully. Keep flammable materials away.

No further step-by-step removal instructions are given in the provided context.
