Measure the weight plane diameter manually, using caliper or tape measure. 
NOTE:  This may need to be done before the wheel is mounted on 
the GSP9720JLR.
Add the measurement from the left weight plane to the desired right weight plane to 
the distance to the inner rim lip and enter this new dimension manually. 
Enter the weight plane distance (mm) and diameter (in) manually.  
Close safety hood. 
Press the green “START” button if “Hood Autostart” is disabled. 
After wheel comes to a complete stop, raise safety hood. 
Place left plane weight (if in DYNAMIC mode) per the balance procedure being 
performed. Refer to “Balancing Procedures,” page 23.
Press the green “START” button with the safety hood in the RAISED position and the 
GSP9720JLR will servo to the location for the right adhesive weight plane (dynamic) 
or the static adhesive weight plane (static), aligned with the first spoke. 
With the servo enabled, attach the adhesive weight behind the first spoke using the 
weight amount shown on the LCD. 
Press the green “START” button with the safety hood in the RAISED position and the
