DESCRIPTION:

New Holland F106.6 F106.6A F156.6 F156.6A Grader Service Repair Manual 

BASIC SAFETY INFORMATION:

This machine is constructed according to the recognized mechanical safety regulations, and using state-of-the-art technology. Nevertheless, when in operation, situations can occur that present serious or mortal dangers to the operator and third parties, or which could cause damage to the machine and other property. The machine should be used only if it is in proper operating condition, and only by operators who are aware of the dangers, know the safety procedures, and have read the operating instructions! The important notes are placed at the start of this section. Immediately repair any faults (or have them repaired) if these could have a prejudicial effect on safety.

1.2 Correct use:

This Grader is principally designed for:
• Creating a double course
• Clearing top soils
• Scarifying old road surfaces and hard ground
• Cutting embankments
• Clearing ice and snow
• Placing, spreading, mixing, and compressing materials.

The Grader can also be used in conjunction with other operating equipment for special applications. The Technical Data provide clear information on this subject. Proper use of the machine also means following the operating instructions and applying the inspection and maintenance conditions. Using the grader for any other purpose, for example:

•  transporting personnel,
•  as a working platform,
•  towing or carrying loads without attaching the proper working attachments, is considered improper use.

Improper use of the machine can pose mortal danger to operating personnel or other persons, or may result in physical injuries, or may cause damage to property.
