Never replace a blown fuse with one of a higher rating. Replacing a 10A fuse with a 20A fuse to "stop it from blowing" can melt your machine's primary wire harness or cause an electrical fire.

Turn the key to the OFF position and disconnect the battery isolator switch (if equipped) before pulling fuses or testing circuits.

When cleaning the cab, use a damp cloth around the rear shroud rather than spraying water anywhere near the seat base or rear paneling.
