3. Put timer during Z-axis operation.
If the tip load attached to the spline tip of the R6YXGLC(P)250, R6YXGLC(P)350, R6YXGLC(P)400, R6YXGLC(P)500 or
R6YXGLC(P)600 exceeds 2kg, the Z-axis may be overloaded depending on the operation pattern.
In this case, put a timer during operation as shown in the Fig. below to prevent overload of the Z-axis. The reference timer values
are shown below. Furthermore, the maximum payload is 4kg. If the tip load exceeds this maximum payload, the Z-axis may be
overloaded easily. So, do not operate the robot with a tip load exceeding 4kg.

5. Detach or attach the Y-axis arm cover.
On the R6YXGLC(P)250, R6YXGLC(P)350, R6YXGLC(P)400, R6YXGLC(P)500, R6YXGLC(P)600 models, the Y-axis arm
cover can be detached/attached only when the Z-axis is at its DOWN end position. For details, see Chapter 2 "9. Detaching or
attaching the covers".
