Introduction
This operating and maintenance manual is designed to facilitate familiarization with your roller,
and to enable you to maintain the compactor and use it for its intended purpose.
When complying with the instructions in the operating and maintenance manual you help avoid
hazards, reduce repair and downtime costs, and increase the reliability and service life of your
roller.
This operating and maintenance manual must always be available at the implementation site of
the roller.
If necessary you can obtain additional information from your authorized WEBER dealer, or you
can obtain information from one of the contact addresses on the last page.
The valid conformity declaration is enclosed with every machine delivery.
You can obtain information on the assembled Kohler diesel engine at www.kohlerpower.it

Safety guidelines
General
All safety instructions must be read and complied with, non-compliance results in
- Danger to life and limb of the user
- Impairments to the machine or other property.
In addition to the operating manual, the accident-prevention regulations in the country where the
appliance is used must be complied with.
Intended use
The roller should only be used in technically faultless condition, as intended, in a safety-conscious
and hazard-conscious manner, in compliance with the instructions in the operating manual.
Malfunctions that impair safety must be eliminated without delay.
The DVH 655 roller is designed exclusively for compacting
- bituminous material (road surfaces); and
- light compaction tasks for earth works
Any other use of the roller is considered to be non-intended use, for which the customer is
exclusively responsible. All liability is rejected if damage occurs due to non-compliance with this
provision. This risk is borne solely by the user.
Easily foreseeable misuse
Any use for which the machine is not intended.
Operating
Rollers are only permitted to be operated by suitable persons of at least 18 years of age. Operators
must be instructed in how to guide the roller by the owner or by owner’s assigned personnel.
The machine operator must comply with trac regulations. If instructions that aect safety are given
by third parties, then the operator must be authorized to reject these instructions.
Protective equipment
Unauthorized persons are forbidden from being in the area of the roller during the compacting
process.
Protective equipment includes:
Hearing protection
Hard hat
Safety shoes
This machine is capable of exceeding the permissible sound level of 80 dB(A). The owner might also
face additional dangers when using the machine. Precautionary action must, therefore, be taken.
Protective gloves

Prior to maintenance and repair work
Only use original Weber spare parts for maintenance or repair work to ensure reliable and safe
operation.
For repair, maintenance, or inspection work the engine of the roller must be safeguarded against
unintentional starting.
All pressurized lines, particularly hydraulic lines and lines of the injection system of the drive motor
must be depressurized before performing maintenance or repair tasks.
For maintenance and repair tasks the roller must be placed on a level and stable substrate and must
be secured from rolling o or tipping over.
Heavy components and assemblies must be secured to and lifted by hoisting machines that can
bear their weight when they are replaced. Ensure that no hazard is caused by raising components or
assemblies.
Do not position yourself or work under suspended loads.
Operation under dicult conditions
Never inhale the exhaust gas; it contains carbon monoxide, a colorless and odorless gas that is
extremely hazardous, which if inhaled even briey can cause unconsciousness and death.
Therefore, never operate the engines in enclosed areas or in areas that are poorly ventilated
(tunnels, caves, etc.). Exercise particular caution when operating the engine in the vicinity of
people and livestock.
Hydraulic hose lines must be checked at regular intervals in accordance with standard engineering
practice, or they must be replaced at appropriate intervals, even if no signs of safety-relevant defects
are present.
Adjusting tasks, maintenance tasks, and inspection tasks must be carried out on schedule as
specied in this operating and maintenance manual. These activities should only be executed by
trained personnel.
Operation
Prior to starting work the owner of the roller must be familiar with the working environment. The
working environment includes obstacles in the work and trac area, the bearing capacity of the
ground, as well as the necessary safeguarding of the construction site in the area adjacent to public
trac; and it also includes compliance with trac regulations.
The roller should only be operated when the protective xtures are mounted. The protective xtures
must all be in functional condition.
At least once per shift the roller must be checked for apparent defects. If there are apparent defects
then operation of the roller must be stopped immediately, and the responsible person must be
informed. Prior to restarting, roller malfunctions that have occurred must be corrected.
If lubricating oils and fuel come into contact with skin, they can cause skin cancer. Upon contact
with the skin, clean aected skin with suitable cleaning agent without delay.
Always maintain adequate clearance to the edges of pits and embankments.
Do not drive on slopes in the transverse direction in order to prevent the roller from tipping over.
After work has been concluded secure the roller in accordance with statutory regulations, particularly
in the area of public trac surfaces.

Inspection
Rollers must be inspected in accordance with the corresponding implementation conditions and
operating conditions, as needed; however an inspection to ensure operationally safe status must be
performed by an expert at least once a year. The results of the inspection must be recorded in writing
and must be stored at least until the next inspection.
Cleaning work
Prior to cleaning the roller with a high-pressure cleaner, protect all accessible energized switches,
cable connections, etc. against water penetration by masking them o.
Cleaning tasks should only be executed in areas that are suitable and have been approved for this
purpose (oil separator amongst others).
Disposal
All operating uids and auxiliary materials must be disposed of in an environmentally-compatible
manner in accordance with country-specic regulations.

Device description
Drive
The compactor is powered by an air-cooled Kohler diesel engine.
Operation
Start the Kohler diesel engine via the electrical start device.
Use the gas lever to vary the engine speed between idle and full throttle.
Forward and reverse as well as the direction of travel are variably controlled via the drive lever
attached to the manual guidance rod.
Also mounted on the manual guidance rod is the lever that is used to switch the vibration on and
o.
The DVH 655 roller is used for compaction work in road building applications.
The two drums are hydrostatically powered via chains. The chain drive is executed individually on
each bandage. The chain drive also serves as a safety braking system for operating on slopes. The
vibrator that is positioned outside between the two drums is powered via a hydraulic motor.
The hydraulic system consists of a closed circuit with hydraulic pumps and hydraulic motors as well
as a hydraulic tank.
The drums are freed of adhering material by the adjustable scrapers.
