Introduction

A Technical Analysis (TA2) is a condensed condition monitoring document. The TA2 contains basic procedures and factory specifications for critical machine systems such as the engine, transmission, and hydraulics. Using a TA2 can help the technician determine whether the machine is operating optimally or requires additional service.

Note: Before adjusting product settings to comply with listed baseline TA2 values, consult SIS for the latest specification values.
