5.3 Maintenance and inspection procedures

The procedures for carrying out the periodic maintenance and inspection are described in this section. Thoroughly

read the contents, and follow the instructions. This work can be commissioned to the Mitsubishi Service Depart

ment for a fee. (Never disassemble, etc., the parts not described in this manual.)

The maintenance parts, etc., required for the customer to carry out maintenance and inspection are described in

Page 92, "5.5 Maintenance parts"

of this manual. Always contact your dealer when parts are needed.

The origin of the machine system could deviate when this work is carried out.
"Review of the position data" and "re-teaching" will be required.
