Print to USB 
The GSP9720JLR has the ability to print data to a USB storage device. “USB Flash 
Drive” is available as a Hunter Approved printer in setup. Selecting this printer 
enables storing of printouts in .PDF format to a USB drive that contains the file 
“printer.txt” in the root directory. 
Printouts are stored using the date and time as the filename with a .PDF extension. 
Printouts are performed just a standard paper printout is, then retrieved from the USB 
Flash Drive and viewed or printed from a standard PC. 
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. 
NOTE:  If the wing nut appears to be tight, remove the wing nut and 
then clean and lubricate the spindle threads. Refer to 
“Spindle Hub Face and Shaft Maintenance,” page 131.
4.7 Diagnosis Explanation Screen (Limits Disabled) 
After the Road Force® Measurement and rim runout measurements have been 
taken, the GSP9720JLR will ask whether or not to perform QuickMatch or 
ForceMatch. If any tire or rim assembly component exceeds a non-first harmonic 
limit, the “Diagnosis Explanation” popup screen will appear to provide a description of 
the component limit(s) exceeded. Refer to “Theory of Operation,” page 133.
Tire and/or rim replacement may be suggested prior to Forcematching®. When a 
severe rim condition is detected, the tire results may be affected. 
4.8 Diagnosis Explanation Screen (Limits Enabled)
