5.8.1.2 Weights Application with SAPE Arm or
with Laser Pointer
- If using the SAPE Arm to place weights, then the arm
m
ust be located at position A as shown in ! gure 5-24.1.
-I f using the laser to place weights, then the arm must
be located at position B as shown in ! gure 5-24.2.
5.8.2 Check Spin
It is good practice perform a check spin after applying
the weights.
• Spin the wheel
Having !
nished the Test Run, if the wheel is balanced
correctly, both the numerical indicators should indicate
0 and an OK should be displayed (Fig. 5-25).
Note:
If there is no OK reading, dynamic
unbalances below the tolerance limit
(suppression preset to 3.5 g) add to a
static unbalance above the tolerance limit.
To check how much imbalance is left:
• Select the FINE key, (21,Fig. 5-25).
Note: The operator should decide if applying
the stated weight is necessary.
5.8.3 Results recalculation
After spinning a wheel it is possible to enter new rim
data or
select another weight mode. The results are
recalculated automatically, if possible.
Selecting another weight mode:
• Between NORMAL, ALU and STATIC: no additional
steps required.
To have a recalculation done:
• Select the preferred Weight Mode. Check and/or
edit rim or plane data when necessary.
• Rotate the wheel to the left plane WAP position and
apply the weight.
• Rotate the wheel to the right plane WAP position
and apply the weight.
• Perform a check spin.
