This Operator’s Manual is intended as a guide for the correct use and maintenance of the machine. Therefore, study it carefully before starting and operating the machine, or before carrying out any preventive maintenance. Keep the manual in the manual box in the cab so that it is always at hand. Replace it immediately if it is lost.
NOTE: The manual describes the applications for which the machine is primarily intended, and is written to apply for all markets. We therefore ask you to disregard the sections that are not applicable to your machine or to the work for which you use your machine.
Many hours are spent on design and production to make a machine that is as efficient and safe as possible. The accidents that occur in spite of this are mostly caused by the human factor. A safety-conscious person and a well maintained machine make a safe, efficient and profitable combination. Therefore, read the safety instructions and follow them.
Every new Volvo Motor Grader is shipped with a CIMA Grader Safety Manual published by the Construction Industry Manufacturers’ Association. Read it carefully before operating or servicing your grader.
We continually strive to improve our products and to make them more efficient through changes to their design. We retain the right to make these changes without committing ourselves to introducing these improvements on products that have already been delivered.
We also retain the right to change data and equipment, as well as instructions for service and maintenance, without prior notice.

Transmission gear display
The transmission gear display is located in the top left-hand side of the pedestal. It displays the transmission gear selected.
With the shift lever in the FORWARD position, the display shows the number of the forward gear, for example ‘3’.
With the shift lever in the REVERSE position, the display shows a negative number, for example ‘-2’.
Refer to Shifting gears page 87.
The gear display can also provide other information: It indicates a Start code sequence on start-up.
It shows an error code if there is a fault in the transmission or All Wheel Drive electrical system.
Start code sequence
When you start the engine, the transmission gear display will show a series of codes called the Start code sequence
Error codes
The transmission ECU (electronic control unit) continuously monitors the transmission and the AWD (All Wheel Drive) electrical system. In the event of a malfunction in either of these systems, an error code is shown in the gear display. Record any error codes and have the electrical system repaired by a qualified service technician. For further information on Error Codes, see the Service manual.
Transmission error codes
If a malfunction occurs in the transmission electrical system, the gear display shows the letter ‘E’ followed by a two-digit numeric code. Multiple error codes are possible. The ECU disables the transmission shifter and places the transmission in NEUTRAL. The display alternates between ‘E’ and the code until the operator returns the shift lever to the NEUTRAL position.
“1.0” series error codes indicate insufficient power available for transmission solenoids. The transmission will not operate until this problem has been resolved.
“2.0” or “3.0” series error codes indicate either an open or short circuit in a transmission solenoid. An alternate gear can be selected by returning the transmission to NEUTRAL. This will allow the grader to be moved.
“2.8” or “3.8” series error codes indicate either an open or short circuit in the parking brake solenoid. The grader will not operate until this problem has been resolved.
“4.2” error code indicates the fault may be corrected by placing the shifter in NEUTRAL then back into gear.
“4.4” error code indicates a multiple shift command error. More than one proximity switch has been energized simultaneously. The circuit board must be replaced to correct this problem.
“4.6” error code indicates there is a problem with the shift lever. The shift lever is out of neutral with no signal to the forward or reverse solenoids.
“P” series error codes indicate a malfunction in the parking brake electrical system.
AWD (All Wheel Drive) error codes
The transmission ECU continuously monitors the AWD electrical system. It is able to detect abnormal conditions and alert the operator of a problem by displaying a code that will aid in correcting the problem.
If a malfunction occurs:
1The transmission gear display shows the letter “E” followed by a 2-digit alphanumeric code. Multiple error codes are possible.
2The display alternates between “E” and the error code until the malfunction is corrected. The transmission is not disabled. Record the error codes and have the AWD electrical system repaired by a qualified service technician. Some error codes will disable the AWD system.
NOTE! “L1”, “L2” and “L4” Series error codes indicate a serious problem with hydraulic oil temperature, level or pressure. Shut the grader down immediately and correct the problem.
