Foreword
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 be-
fore carrying out any preventive maintenance.
Keep the manual in the manual box in the cab so that it is al-
ways 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 ap-
ply 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 acci-
dents that occur in spite of this are mostly caused by the hu-
man 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 Grad-
er Safety Manual published by the Construction Industry
Manufacturers’ Association. Read it carefully before operat-
ing or servicing your grader.
We continually strive to improve our products and to make
them more efficient through changes to their design. We re-
tain the right to make these changes without committing our-
selves 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 pri-
or notice.
SAFETY REGULATIONS
It is the operator’s obligation to know and follow the applica-
ble national and local safety regulations. The safety instruc-
tions in this manual only apply to cases when there are no
national or local regulations.
WARNING!
The symbol above appears at various points in the
manual together with warning text. It means – Warning,
be alert! Your safety is involved. It is the obligation of
the operator to make sure that all warning decals are in
place on the machine and that they are readable.

Foreword
4 Communication equipment, installation
Communication equipment,
installation
IMPORTANT!
All installations of electronic communication equipment must be
performed by trained professionals and in accordance with Volvo
Construction Equipment instructions applicable to the specified
machine.
Protection from electromagnetic interference
The Volvo Motor Grader is equipped with multiple ECUs that were tested
for Electro Magnetic Compliance. This means that the ECUs are immune
to electromagnetic interference at the levels prescribed in the internation-
al standards. However, if improper installation and use of communication
equipment exceed the limits of these components, the machine may mal-
function. Therefore, it is very important that all non-approved electronic
accessories, such as communication equipment, be tested before the
machine is put into service.
Mobile telephones
To obtain the best functionality, mobile telephones should be permanent-
ly installed in the electrical system of the grader with a permanently fixed
antenna on the cab, installed as advised by the manufacturer.
If a portable mobile telephone is used, note that it can constantly transmit
information to its base station, even when the telephone is not used. For
this reason, it should not be located beside electronic equipment in the
machine, such as directly on a control panel, etc.
Guidelines
The following guidelines must be followed during installation:
– The antenna placement must be chosen to give good adaptation to
the surroundings.
– The antenna cable must be of the coaxial type. Be careful to ensure
the cable is undamaged, that the sheath and braid are not split at the
ends, and the braid covers the connector ferrules and has good gal-
vanic contact with them.
– The mating surface between the antenna mounting bracket and the
bodywork must have clean metal surfaces, with all dirt and oxide re-
moved. Protect the mating surfaces against corrosion after installation
to maintain good galvanic contact.
– Remember to separate interfering and interfered cables physically. In-
terfering cables consist of the communication equipment’s supply ca-
bles and antenna cable. Interfered cables are those which are
connected to electronic devices in the machine. Install the cables as
close as possible to grounded sheet metal surfaces, since the metal
has a shielding effect.

General
Intended use
The machine is intended to be used under normal conditions for
the operations described in the Operator’s Manual. If it is used for
other purposes or in potentially dangerous environments, for ex-
ample, an explosive atmosphere, areas with dust containing as-
bestos, etc., special safety regulations must be followed and the
machine must be equipped for such use. Contact the manufactur-
er or dealer for further information.
Engine
The engine is a four stroke cycle, in line six cylinder, turbocharged
diesel with overhead valves and air-to-air charge air cooler. These
engines are of the low emission type and all models have VHP
(Variable horsepower).
VHP
All Volvo grader models have engines that provide 2 different pow-
er levels depending on the gear selected by the operator.
– For non-All Wheel Drive equipped graders, forward gears 1,
2, and reverse 1, have reduced power to minimize wheel slip.
In forward gears 3 through 8, and reverse gears 2 through 4,
engine power is automatically increased.
– For All Wheel Drive equipped models with the All Wheel Drive
system turned OFF, the function of the VHP is the same as
above.
– For All Wheel Drive equipped models with the All Wheel Drive
turned ON, the engine power is increased for all gears.
– There is no operator selectable control over the VHP system.

8 General
Electrical system
The electrical system is a 24VDC, negative-ground system. Pow-
er is supplied by two 12VDC batteries connected in series. Battery
charging is accomplished using a standard 75 amp alternator and
an optional 100 amp alternator. Electrical power can be discon-
nected using a ground isolation switch.
Clutch
A multiple wet disc clutch is mounted to the engine flywheel and
connected to the transmission with a driveshaft. The clutch must
be used when starting to move or when changing direction.
Transmission
The transmission has eight forward and four reverse speeds. It is
a fully sequential, direct drive, powershift unit utilizing a counter-
shaft design.
Final drive/tandems
Final drives are single reduction in models G710B to G746B and
double reduction in the G780B. Each has an operator controlled
lock/unlock differential. Rear axles are case hardened, full floating
design, supported on double row spherical roller bearings. Tan-
dem wheels are chain-driven.
Brakes
Hydraulically actuated, oil disc service brakes are located at the
four tandem drive wheels. The crossover dual braking circuits pro-
vide even braking on both sides of the grader.
If the engine stalls, or hydraulic boost pressure becomes unavail-
able, full braking capability is available through a reserve system.
An electric motor supplies the power required to bring the grader
to a safe stop.
The parking brake is a spring apply/hydraulic release, disc-type
brake. It is driveline-mounted to the transmission output shaft. An
accumulator in the circuit stores system pressure allowing the
brakes to remain released in the event of system pressure loss for
about 15 minutes.
Steering
The steering system is a closed-center dynamic signal load sens-
ing system. The hydraulic steering system incorporates two steer-
ing cylinders. The leaning wheel feature and articulated frame can
be used to decrease turning radius. There is no manual steering.
Cab and frame
Both the canopy and fully-enclosed cab are equipped according to
the ROPS standard. FOPS approved structures are optional. En-
closed cabs are also provided with air conditioning and/or heating
systems as options. All controls are housed in the fully adjustable
steering pedestal and the right-hand side console. Ergonomic
seating and hydraulic control lever placement ensure operator
comfort and efficiency. The frame articulates 22° to the left or to
the right and uses anti-drift lock valves to ensure stable operation.

MBCS (Moveable Blade Control System)
Blade mobility permits steep ditch cutting angles and back sloping
outside of overall machine width. The circle is held in place by ad-
justable clamp plates and guide shoes. Bearing surfaces are DU-
RAMIDE™-faced to maximize service life. Hardened teeth are cut
on the outside of the circle. Oil is directed to the two drive cylinders
by a circle timing valve. The cylinders are arranged 90° out of
phase to ensure consistent power. The moldboard is provided with
replaceable cutting edge and end-bits. The drawbar is a narrow
“T” design for optimum visibility to the work area.
Hydraulic system
The closed-center hydraulic system uses a pressure and flow
compensated (load-sensing) variable displacement piston pump.
The pump supplies oil to the implements, the steering and the en-
gine cooling fan system.
The cooling fan is driven by a fixed displacement vane-type motor.
Fan speed is variable and is determined by various cooling re-
quirements. The fan operates between pre-determined minimum
and maximum speeds. The fan remains at its minimum speed until
there is a demand for cooling. Fan speed will automatically in-
crease with the demand for cooling.
Lock valves (counterbalance valves) are incorporated into the
blade lift, moldboard tilt, circle shift, wheel lean and articulation cir-
cuits to prevent cylinder drift. The control levers are short throw,
feathering type located on an adjustable steering pedestal.
All Wheel Drive
G726B and G746B are All Wheel Drive models. The system oper-
ates in gears 1 through 7. It is powered by two electronically con-
trolled, variable displacement hydraulic pumps in a closed loop
system. Each pump supplies one front wheel motor.
Front wheel motors are two-speed, high torque, radial piston, cam
lobe type. Each wheel motor has a separate speed sensor.
The system has a 16-speed aggression control dial.
Equipment and attachments
The circle, drawbar and moldboard equipment is fully maneuver-
able using hydraulic cylinders. Optional attachments include:
– Dozer blade
– Rear-mounted ripper-scarifier
– Mid-mounted scarifier
– Front-mounted scarifier
– Windrow eliminator
– Push block (counterweight for ripper)
– One-way plow
–V-plow
– Hydraulic snow wing (high and low bench)
– A-frame (used with V-plow and One-way plow only)

10 CE Marking and Declaration of Conformity
CE Marking and Declaration of
Conformity
(Only applies to machines marketed within the EU/EEA).
This machine is CE marked. This means that when delivered the
machine meets the applicable “Essential Health and Safety Re-
quirements”, which are given in the EU Machinery Safety Direc-
tive.
If changes are made that affect the safety of the machine, the per-
son carrying out the changes is responsible for the same.
As proof that the requirements are met, the machine is supplied
with an EU Declaration of Conformity, issued by Volvo Motor
Graders Limited for each separate machine. This EU Declaration
also covers attachments made by Volvo Motor Graders Limited.
This documentation is a valuable document, which should be kept
safe and retained for at least 10 years. The document should al-
ways accompany the machine when it is sold.
If the machine is used for other purposes or with other attach-
ments than described in this manual, safety must at all times and
in each separate case be maintained. The person carrying out
such action is also responsible for the action that, in some cases,
may require a new CE marking and the issue of a new EU Decla-
ration of Conformity.
EU EMC Directive
The electronic equipment of the machine may in some cases
cause interference to other electronic equipment, or suffer from
external electromagnetic interference, which may constitute safe-
ty risks.
The EU EMC directive on “Electromagnetic conformity” provides a
general description of what demands can be made on the ma-
chine out of a safety point of view, where permitted limits have
been determined and given according to international standards.
A machine or device, which meets the requirements, should be
CE marked. Our machines have been tested particularly for elec-
tromagnetic interference. The CE marking on the machine and the
declaration of conformity also covers the EMC directive.
If other electronic equipment is fitted to this machine, the equip-
ment must be CE marked and tested on the machine as regards
to electromagnetic interference.
