Cooling system flushing is essential to
prevent the cooling system from clogging
up with salt, sand, or dirt. In addition, fog-
ging of the engine is mandatory to pre-
vent excessive engine damage due to
rust. Perform the flushing and fogging at
the same time.
WARNING

Do not touch or remove electrical parts
when starting or during operation.
●
Keep hands, hair, and clothes away from
the flywheel and other rotating parts

minutes in neutral position.
