Introduction

This Special Instruction provides information for the installation of the AccuGrade Attachment Ready Option (ARO) on M Series, M Series 2, and M Series 3 Motor Graders.

Important Safety Information

Work safely. Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs.

A person must be alert to potential hazards. This person should also have the necessary training, skills, and tools to perform these functions properly.

Safety precautions and warnings are provided in this instruction and on the product. If these hazard warnings are not heeded, bodily injury or death could occur to you or to other persons. AVSpare cannot anticipate every possible circumstance that might involve a potential hazard.

Therefore, the warnings in this publication and the warnings that are on the product are not all inclusive. If a tool, a procedure, a work method, or operating technique that is not recommended by AVSpare is used, verify that the procedure is safe for you and for other people to use.

Ensure that the product will not be damaged or the product will be made unsafe by the operation, lubrication, maintenance, or the repair procedures that are used.

------ WARNING! ------

Do not operate or work on this machine unless you have read and understand the instructions and warnings in the Operation and Maintenance Manual. Failure to follow the instructions or heed the warnings could result in injury or death. Contact your AVSpare dealer for replacement manuals. Proper care is your responsibility.


------ WARNING! ------

Personal injury or death can result from improper assembly procedures.

Do not attempt any assembly until you have read and understand the assembly instructions.


------ WARNING! ------

Sudden movement or accidental starting of the machine can cause personal injury or death to persons on or near the machine.

To prevent personal injury or death, perform the following:

Park the machine on a smooth level surface.

Lower the blade and or attachments to the ground.

Stop the engine and engage the parking brake.

Block the wheels and install the steering frame lock.

Turn the battery disconnect switch to the OFF position and remove the key.

Place a Special Instruction, SEHS7332, "Do Not Operate" tag at the battery disconnect switch location to inform personnel that the machine is being worked on.
