6. Inspection/Maintenance
6.2.3 Checking the Belt Tension
6.2.4 Checking the Belt Tension for the Vertical Axis
Using a push-pull gauge, push the timing belt for vertical axis with a force of 300 gf and measure the
amount of deflection.
If the deflection is 2.4 mm, the belt tension is normal.
If the deflection is not 2.4 mm, adjust the tension by referring to 6.2.6, “Adjusting the Belt Tension for the
Vertical Axis.”
z When measuring deflection, do not use a gauge with a sharp tip that may damage the belt.
