Introduction

Periodic inspections and maintenance are extremely important in assuring that
the YAMAHA robot will perform safely and efficiently. This chapter covers the
procedures by which periodic inspections of the YAMAHA YP-X Series are car-
ried out, as well as the items to be inspected and information on maintenance.
! DANGER
• If the adjustment or maintenance procedure calls for operation of
the robot, stay out of the working area of the manipulator while it is
operating. Do not touch any parts inside the controller. Keep watch-
ing the manipulator movement and surrounding area so that the
operator can press the emergency stop button if any danger oc-
curs.
WARNING
• When the robot does not need to be operated during adjustment
or maintenance, always turn off the controller and the external
switch board.
• Do not touch the internal parts of the controller for several sec-
onds after the power to the controller has been turned off.
• When performing electrical maintenance which does not require
manipulator movement, keep the emergency stop button pressed.
• Use only the lubricants or grease specified by YAMAHA or the
YAMAHA sales dealer.
• Use only the parts specified by YAMAHA or the YAMAHA sales
dealer. Take sufficient care not to allow any foreign matter to con-
taminate them during adjustment, parts replacement or
reassembly.
• Do not alter any part of the manipulator or controller. Doing so
may result in unsatisfactory specifications or may threaten the
safety of the operator.
• When adjustment or maintenance is complete, retighten the bolts
and screws securely.
• During robot adjustment or maintenance, place a sign indicating
that the robot is being adjusted or inspected, to prevent other
persons from inadvertently touching the control keys or switches.
Provide a lock on the switch keys or ask someone to keep watch
as needed.
