Preface
These operating and maintenance instructions are intended to acquaint you with your soil
compactor, to assist you in the proper maintenance of the machine and to enable you to use it to
the full extent of its intended capabilities.
Acting in accordance with these operating and maintenance instructions will help to avoid
danger, to reduce repair costs and downtimes and to increase the reliability and life of your soil
compactor.
These operating and maintenance instructions manual must be always at hand at the soil
compactor's place of use.
In case of need, you will get further information from your authorized WEBER distributor or one
of the contacts listed on the last page.
The valid conformity declaration is enclosed with every machine delivery.

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 binding accident prevention guidelines in the country where
the compactor is used must be complied with.
Proper use
The soil compactor 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 CR 12 soil compactor is designed exclusively for compacting
- Sand
- Gravel
- Crushed aggregates
- Semi-cohesive mixed material
Any other use of the soil compactor is considered to be improper use for which the owner shall be
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.
Driving
Soil compactors should only be driven by suitable personnel at least 18 years of age, Drivers must be
instructed in how to guide the compactor by the owner or by owner’s assigned personnel.
The machine operator must comply with trafc regulations. If instructions that affect safety are given
by third persons, then the operator must be authorized to reject these instructions.
Unauthorized persons are forbidden from being in the area of the soil compactor during the
compacting process.
Protective equipment
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 equipment includes:
Ear protection
Hard hat
Safety shoes
Protective gloves

Prior to maintenance and repair work
Only use original Weber spare parts to ensure reliable and safe operation for maintenance or repair
work.
For repair, maintenance, or inspection work the engine of the compactor 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 compactor must be parked on a level and stable substrate and
must be secured from rolling off or tipping over.
Heavy components and subassemblies must be secured on hoisting machines with adequate bearing
capacity when they are replaced. Ensure that no hazard exists related to the raised components or
subassemblies.
Do not position yourself or work under suspended loads.
Operation under difcult 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.
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 executed on schedule as specied
in this operating and maintenance manual. These activities should only be executed by instructed
personnel.
Operation
Prior to starting work the owner of the compactor must be familiar with the work environment. The
work environment includes obstacles in the work and trafc area, the bearing capacity of the ground,
as well as the necessary safeguarding of the construction site in the area adjacent to public trafc;
and it includes compliance with trafc regulations.
The soil compactor 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 compactor must be checked for apparent defects. If there are apparent
defects then operation of the compactor must be stopped immediately and the responsible person
must be informed. Prior to restarting, compactor 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 affected skin with suitable cleaning agent without delay.
CR 12 7
Inspection
Compactors must be inspected in accordance with appropriate 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 until the next inspection.
Cleaning work
Prior to cleaning the compactor with a high-pressure cleaner, protect all accessible energized
switches, cable connections, etc. against water penetration by masking them off.
Cleaning tasks should only be executed in areas that suitable and approved for this purpose (oil
separator).
Disposal
All operating uids and auxiliary materials must be disposed of in an environmentally-compatible
manner, in accordance with country-specic regulations.
Important information for operating and maintenance personnel is marked by pictograms.
