Connect a vacuum tank (capacity: 10
liters) to the vacuum pump assembly through a vacuum

build-up. If the gauge reading
deviates from the specified standard value, replace the
vacuum pump.

1.Push the V-belt at its
midpoint with a force of approximately 98 N as shown and
read the
amount of deflection A.
2.If the reading deviates
from the specified standard value, accomplish the following
adjustment.

3.Loosen the bolt and nut
holding the generator, and adjust the tension of the V-belt
using
the adjusting bolt.
| caution |
- Be sure to retighten the bolt and nut
securely
after the adjustment.
- Excessive tension damages not only the
V-belt itself but bearings
elsewhere.
- Be sure to replace the V-belt, when
necessary, in pairs and keep it
