8-5 Replenishing the grease
8-5-1 Replenishing grease to the linear guide
The X-axis, Y-axis and Z-axis (ZF) use a linear guide as the linear guide mecha-
nism. 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.
!
CAUTION
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.
!
CAUTION
If the X-axis stroke is 2150mm or more for the FXYBX, or 2450mm or more for
the SXYBX, a slider mechanism is provided in the X-axis stroke cover to sup-
port the inner self-weight.
When removing the X-axis stroke cover, do not pull it up and off. Instead, pull it
with a parallel movement in respect to the axis movement direction, to remove
the stroke cover from the slider. Then, pull it upward and off.
1) Turn 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.
