WARNING
7.1 General Maintenance
This equipment is designed and constructed to provide many years of
trouble-free performance when properly operated and maintained. However, no
machine can perform to the utmost of its ability without proper maintenance. To
maintain good performance, check the following points monthly.
• Check all cables. If damaged, replace.
• Check connectors at rear of the Surface Processor Unit. Tighten or clean as
necessary.
• Check ground of Surface Processor Unit. Tighten or clean as necessary.
• Check voltage of power source to be sure it is within the equipment’s power
rating.
• Dust or dirt can be removed from the Surface Processor Unit with a soft, dry
cloth. Do not use chemical cleaners to clean the unit – they can remove paint
and markings or deform the equipment.
7.2 Replacement of Fuse
The 2A fuse on the rear panel of the
Surface Processor Unit protects the
equipment from overvoltage and
equipment fault. If the power cannot be
turned on, check if the fuse has blown
and find out the reason why it blew. If
the fuse blows after replacement,
contact your dealer for advice.
WARNING
Use the proper fuse.
Use of a wrong fuse can result in damage
to the equipment or cause fire.
