Introduction

Inspections are the most basic form of condition monitoring. Inspections are easy to do and surprisingly effective at helping you spot equipment health issues. Proactive monitoring and analysis of equipment information will allow Dealers to intervene effectively before problems occur.

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

Note: Specification values are based on the following machine settings unless stated otherwise

• Engine Speed Dial "10"

• AEC OFF

• HP Mode
