OPERATIONS INSIDE THE ENGINE COMPARTMENT
PERIODIC INSPECTION AND MAINTENANCE

NOTE: This operation is to temporarily set the
preset data such as the belt specifications,
because if the measurement is taken without input
of the belt specifications, conversion to tension
value (N) cannot be made, resulting in judgement
of error.
<Setting procedure>
(1) Press down the "MASS" button till the belt
mass select display appears.
(2) Press the "UP" or "DOWN" button to select "01
1.5GT 0.9" and press the "MEASURE" button
to decide it.
Check to ensure that "M 000.9 g/m" is
displayed.
(3) Press the "WIDTH" button to change to the
belt width input display.
(4) Press number keys 0, 1, 0, and 0 sequentially,
and press the "SELECT" button to apply them.
Check to ensure that "W 010.0 mm/R"
appears on the display.
(5) Press the "SPAN" button to change to the
span length input display.
(6) Press number keys 0, 1, 0, and 0 sequentially,
and press the "SELECT" button to apply them.
Check to ensure that "S 0100 mm" appears on
the display.
4. Press "Hz" button twice to change the display to
the frequency display (Hz).
CAUTION
•
The temperature of the surface of the belt
should be as close as possible to normal tem-
perature.
•
Do not let any contaminants such as water or
oil get onto the microphone.
•
If strong gusts of wind blow against the
microphone or if there is loud sources of
noise nearby, the values measured by the
microphone may not correspond to actual
values.
•
If the microphone is touching the belt while
the measurement is being made, the values
measured by the microphone may not corre-
spond to actual values.
•
Do not take the measurement while the vehi-
cle's engine is running.
5. Hold the microphone to the middle of the drive
belt between the pulleys (at the place indicated by
the arrow), about 10
−
15 mm away from the rear
surface of the belt and so that it is perpendicular
to the belt (within an angle of
±
15
°
).
6. Press the "MEASURE" button.
7. Gently tap the middle of the belt between the
pulleys (the place indicated by the arrow) with
your finger as shown in the illustration, and check
that the vibration frequency of the belt is within the
standard value.
NOTE: To take the measurement repeatedly, fillip
the belt again.
8. After the completion of the measurement, press
and hold the "POWER" button to turn off the
power supply.
