Adjusting the Tension of the Spindle Belt
This adjustment is required only for the belt for the high-torque spindle (ZS-650T/ZS-500T). We recommend checking it after approxi-
mately every 1,000 hours of working time.
First check the tension of the spindle belt. If this shows that the tension is outside the reference value, then adjust the tension.
Two special tools, a tension gauge (ST-001) and a tension adjuster (ST-040), are required to check the tension. These tools are sold
separately as service parts. Contact your authorized Roland DG Corp. dealer or service center.
Remove the screws shown in the figure and detach the
spindle motor cover.
(This requires a commercially available flathead screw-
driver.)
1
Loosen each of the four screws securing the spindle
motor one half-turn.
(This requires a commercially available hexagonal
wrench [size: 4 mm]. Use a tool with a ball-bit shape or
ordinary shape and measuring at least 100 mm in length.)
