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 A (gf) and measure the
amount of deflection.
If the deflection is B (mm), the belt tension is normal.
If not, adjust the belt tension by referring to 6.2.6, “Adjusting the Belt Tension for the Vertical Axis.”
Type A B
IX-HNN50/60
IX-INN50/60
340 ~ 410 (gf) 1.35 (mm)
IX-HNN70/80
IX-INN70/80
550 ~ 650 (gf) 2.2 (mm)
 When measuring deflection, do not use a gauge with a sharp tip that may damage the belt.
