Locating The Wheel Weights At The Top Dead Center ("Tdc") And Bottom Dead Center ("Bdc") - Hunter DSP9200 Series Operation Instructions Manual

3.4 Locating the Wheel Weights at the Top Dead Center ("TDC")
and Bottom Dead Center ("BDC")
32 x 3. Balancing a Wheel
Clip-on weights are always located at TDC and adhesive tape-on weights are always
located at BDC as shown on the weight indicator display.
Find TDC by turning the wheel until the Green Arrow and the Center LED on the
weight indicator are both "ON" (see the left plane weight indicator in the illustration
below). In this position, a balance weight has to be attached at top dead center. To
automatically position weights at TDC or BDC, refer to "Motor Drive/Servo-Stop,"
page 49.
To apply wheel balancing weights at TDC (12 o'clock position), align the weights with
the white line on the spindle housing. The line is used to accurately locate the TDC
position.
When the weight indicator LED bar is blinking, it indicates that the weight location is
more than 90 degrees from TDC (on the hidden side of the wheel). When the green
arrow is blinking, it indicates that the weight location is at BDC. The illustration below
shows the wheel positioned at TDC for placement of the left plane weight, while the
right plane weight position is 180 degrees from TDC (Bottom Dead Center - BDC).
