“<MIN CAL” after attempt is
made to Calibrate. The LSS Module expected the empty platform to weight more for calibration.
1. The platform is being supported by something other than the four Shear Pin Load
Cells. This includes binding between the slide block/spacer bushing/arm tube
assembly (bushing should be free enough to rotate by hand). For proper operation,
the platform’s entire weight must be transferred through the Shear Pin Load Cells
and into the arm support structure for an accurate calibration.
2. The wrong Model Selection was made under the LSS Module’s MACHINE SETUP,
MODEL. This should be set to the proper MODEL (4069LE, 3369LE, 500RTS,
260MRT or SCISSOR). Improper selection may lead the LSS Module to expect dif-
ferent empty platform weights.
3. The calibration difficulty may be a result of a Measurement Performance issue.
Review the Possible Resolutions under that category.

CAL” after attempt is made to
Calibrate. The LSS Module expects the empty platform to weigh less for calibration.
1. Tools, debris, or customer-installed accessories have not been removed before cal-
ibration. The LSS Module must tare an empty platform and its optional JLG Acces-
sories.
2. The wrong Model Selection was made under the LSS Module’s MACHINE SETUP,
MODEL. This should be set to MODEL (4069LE, 3369LE, 500RTS, or 260MRT).
Improper selection may lead the LSS Module to expect different empty platform
weights.
3. The calibration difficulty may be a result of a Measurement Performance issue.
