Yanmar FX42D Extra Battery Notes
Basic battery safety
Disconnect the negative cable first, then disconnect the positive cable. Install the new battery, connect the positive cable first, then reconnect the negative cable last. That reduces the chance of shorting a tool against the frame.
Official information note
Mistakes do happen. Battery specs can change by year, engine, market, terminal layout and installed options. Check the old battery label, operator manual, parts book and official yanmartractor.com website before ordering a replacement battery.
