5 Periodic inspections
The inspection periods and general precautions are described in Chapter 4 Peri-
odic Inspections. Always refer to that Chapter before starting this work.
WARNING
Always turn the controller power OFF before starting periodic inspec-
tions. Serious accidents could occur if the robot starts moving during the
periodic inspection.
WARNING
The motor and speed reduction gear casing are extremely hot after auto-
matic operation, so burns may occur if these are touched. Before han-
dling these parts, turn OFF the controller, wait for a while and check that
the part has cooled.
5-1 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 specification drawings, etc.
1) Turn the controller power OFF.
NOTE
When the ZF 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 "1.
Installation" for details on removing the X-axis cover.)
