WARNING: In case lubrication operation is
unavoidably performed indoors, open windows and
doors to maintain good air ventilation to prevent
asphyxiation. Lubricant property will deteriorate
even if the machine is kept stored. Check all lubricants
before operating the machine after being stored.
Apply the parking brake while storing.
If the machine is to be stored for more than one month, observe the following precautions so that its function will not be
impaired during storage.
