5. Cooling system flushing is essential to
prevent the cooling system from clog-
ging up with salt, sand, or dirt. In addi-

WARNING! Do not touch or remove
electrical parts when starting or dur-
ing operation. Keep hands, hair, and
clothes away from the flywheel and
other rotating parts while the engine
is running.
