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.
Accidents may otherwise occur.
Know the capacity and limits of your machine!
This manual applies to Serial Number 35000 and up.

The rear wheels are not driving when Creep Mode is activated. NOTE! Selecting Creep Mode eliminates any memory gear combination previously used.

  • Page 93: Steering

    If the engine stalls, stop the grader. Place transmission in NEU- TRAL and apply the parking brake. Start the engine, if possible. If the engine cannot be started, refer to Stopping the machine page 98. Have the engine repaired by a qualified Volvo service techni- cian. Front wheel lean You can reduce the turning circle of your grader by leaning the front wheels.
  • Page 94 Check the system by turning the steering wheel. If it does not turn easily, there is a fault in the system. Have the system re- paired by a qualified Volvo service technician. Depress and hold the Secondary steering test button only long enough only to check the system.

    Operating instructions Braking Braking Service brakes Push down on the brake pedal to apply the service brakes. WARNING! In case of faulty brakes, do not continue to operate. Have a qualified service technician repair the brake system immediately. The service brake system has two separate brake circuits. The system provides reduced braking capability in the event of a brake line rupture or other failure in one circuit.
  • Page 96 Operating instructions Braking Parking brake NOTE! Only apply the parking brake when the machine has stopped. Always apply the brake if the machine is to be left unattended. NOTE! When the parking brake is applied, the transmission cannot be shifted out of neutral. When the parking brake is applied, the red indicator lamp (B) illu- minates.
