78 4. Balancing a Wheel GSP9700 Series Road Force Measurement System Operation
Inflation Pressure
Inflation pressure of each tire, as recorded by the Inflation Station, is displayed on the
summary printout. A blank reading indicates that the tire was not measured (inflated
or deflated) with the Inflation Station feature.
Summary printout will print the tire pressure rounded to the nearest tenth of a pound.
The range allowable to fill each tire may vary on the printout by one or two pounds
per assembly. This is considered normal due to the “green bar” tolerance allowable
during automatic inflation.
4.8 Quick-Thread™ Feature
Quick-Thread™ is an “intelligent” DC drive motor control feature that allows motor
assisted threading for fast installation and removal of the GSP9700 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 your 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 your right hand, hold one handle of the wing nut while you are still 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 (refer to “Spindle-Lok
®
Feature,” page 79) 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, you must still
perform the final tightening of the wing nut.
NOTE: Also because of the software limited torque control, you
must loosen the wing nut before Quick-Thread will remove
it.
Quick-Thread will not operate if:
You are in “Diagnostics,” “Setup,” or all calibration procedures except
“Servo-Stop.”
