4. Regular inspection

Others/driving system
V-Belt
The tension of the V-belts should be checked daily .
1. Change the V-belts if necessary
1) If in the case of a multiple V-belt drive, wear or
differing tensions are found, always replace the
complete set of V-belts.
2. Checking condition
1) Check V-belts for cracks, oil, overheating and wear.
3. Testing by hand
DV2213047A_E
1) For the V-belt tension, when you press the center
between pulleys, if it is pressed by 10~15mm, it is
normal.
2) To check the tension of V-belt more accurately, you
can use a V-belt tension gauge.
4. Tension measurement
1) Lower indicator arm (1) into the scale.
DV2213048A
2) Apply tester to belt at a point midway between two
pulleys so that edge of contact surface (2) is flush
with the V-belt.
DV2213049A
3) Slowly depress pad (3) until the spring can be heard
to disengage. This will cause the indicator (1) to move
upwards.
Note) If pressure is maintained after the spring has disen-
gaged a false reading will be obtained.
4) Read the tension value at the point that the top
surface of indicator arm(1) intersects with the scale.
5) Before taking readings makes ensure that the indicator
arm remains in its position.
Note) If the value measured devotes from the setting
value specified, the V-belt tension must be
corrected according to the following table.
