With the left hand, hold the rim over the cone to remove the weight of the rim from
the spindle and to allow maximum quick-thread wing nut travel.
Place the wing nut on the spindle and rotate one full turn onto the spindle threads.
With the right hand, hold one handle of the wing nut while lifting the rim.
NOTE: Heavier wheel assemblies may require extra lifting to
prevent the software limited motor torque control from
stopping the rotation of the spindle.
Tap the foot pedal twice and the spindle will rotate to install the wing nut to save
threading time.
A single tap within the first three seconds of rotation will reverse the direction of
rotation. A single tap after the first three seconds of rotation will stop rotation.
Quick-Thread spindle rotation will stop when the clamping components contact the
wheel, or when the foot brake is applied for more than half of a second.
CAUTION: Quick-Thread does not tighten the wing nut! In Quick-
Thread rotation, torque allowed is minimal. Therefore, the
wing nut must still be hand-tightened before balancing.
3.3 Quick-Thread® Wheel Clamping
Quick-Thread® is an “intelligent” DC drive motor control feature that allows motor
assisted threading for fast installation and removal of the GSP9720JLR wing nut.
Quick-Thread can be enabled or disabled from the “Setup” screen.
WARNING: Keep clear of clamping components during Quick-
Thread shaft rotation.
Lift the wheel assembly onto the shaft as normal without threading on the wing nut.
With the left hand, hold the rim over the cone to remove the weight of the rim from
the spindle and to allow maximum quick-thread wing nut travel.
Place the wing nut on the spindle and rotate one full turn onto the spindle threads.
With the right hand, hold one handle of the wing nut while lifting the rim.
NOTE: Heavier wheel assemblies may require extra lifting to
prevent the software limited motor torque control from
stopping the rotation of the spindle.
Tap the foot pedal twice and the spindle will rotate to install the wing nut to save
threading time.
The direction of spindle rotation toggles each time it is used. For normal operation,
spindle rotation will begin in the correct direction for wing nut installation. A single tap
within the first three seconds of rotation will reverse the direction of rotation. A single
tap after the first three seconds of rotation will stop rotation.
Quick-Thread spindle rotation will stop when the clamping components contact the
wheel, or when the foot brake is applied for more than half of a second.
