When starting from another machine, make sure machines do not touch. This prevents sparks near the battery, which could ignite hydrogen gas and explode battery. Always wear eye protection when starting machine from external power source. To prevent possible personal injury, use care when removing cables from machine that has been started. Do not allow cable ends to contact each other or the machine.
