15. Guaranty The guaranty (compensation) is limited to this product. (There are no secondary guaranty.)
16. Cautions (1) Be sure to hold the case to carry the body. By holding the wire, there is a risk of wire disconnection
and/or short circuit.
(2) When routing the wire of the brush, do it at least once inside the ground. (It is called the draining
processing.) By not doing so, water is likely to infiltrate inside the body through the wire.
(3) Expose the joint between the rotary brush and the swivel joint to the atmosphere so that air can flow.
By not doing so, the water removed out of the body is likely to re-enter the body as steam.
(4) Do not close the draining hole in the base part.
