WARNING
• ALWAYS TURN THE CONTROLLER POWER OFF BEFORE STARTING PERIODIC
INSPECTIONS. SERIOUS ACCIDENTS COULD OCCUR IF THE ROBOT STARTS MOVING
DURING THE PERIODIC INSPECTION.
• THE MOTOR AND SPEED REDUCTION GEAR CASING ARE EXTREMELY HOT AFTER
AUTOMATIC OPERATION, SO BURNS MAY OCCUR IF THESE ARE TOUCHED. BEFORE
HANDLING THESE PARTS, TURN OFF THE CONTROLLER, WAIT FOR A WHILE AND
CHECK THAT THE PART HAS COOLED.
3. Replenishing grease to the linear guide
Grease must be replenished to this linear guide periodically. Select the grease from the
following recommended types.
Recommended grease
: Alvania No. 2 (Showa Shell)
Daphne Eponex No. 2 (Idemitsu)

CAUTION
When designated by YAMAHA and the user, special grease, such as splatter-
proof grease, may be applied when the robot is delivered. In this case, apply the
appropriate grease as indicated in the delivery specifi cation drawings, etc.
1) Turn the controller power OFF.
When the ZFL unit is attached for the 3rd-axis, the replenishment work can be
carried out easier by moving the Z-axis slider to near the motor (near the origin) and
turning the controller power OFF.
2) Place a sign indicating “Work In Progress” so that other operators do not turn the
controller power ON.
3) Remove the axis stroke cover when replenishing grease. (Refer to section "2.
Installation" for details on removing the X-axis cover.)
