This section describes PF Timing Belt tension adjustment.
Tools
Sonic tension gauge
Plastic tweezers
Adjustment procedure
1. Set the following parameters to the sonic tension gauge.
Weight: 001.2 g/m
Width: 005.0 mm
Span: 0048 mm
2. Bring the microphone of the sonic tension gauge close to the upper center of the PF Timing Belt.
3. Press the “MEASURE” button on the sonic tension gauge and flip the timing belt with plastic tweezers.

4. The adjustment is not necessary if the measured value falls within the standard value.
If not, loosen the screws that secure the PF Motor, and change the position of the PF Motor adjuster part of
the PF Motor attachment location little by little to adjust the belt tension. Repeat Step 3 until the measured
value falls within the standard value.
When performing the PF Timing Belt tension measurement, make sure of the following.
Bring the microphone of the sonic tension gauge within 5 mm from the Timing Belt but do
not let it touch the belt.
Flip the Timing Belt as weak as the sonic tension gauge can measure it.
Be careful not to damage the Timing belt when flipping it with the plastic tweezers.
The standard tension range of the PF Timing Belt Tension Adjustment is as follows:
Standard value: 10.5 2N (8.5 - 12.5N)
