Introduction
This operating and maintenance manual is designed to facilitate familiarization with your soil
compactor, 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
compactor.
This operating and maintenance manual must always be available at the implementation site
of the soil compactor.
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 Honda gasoline engine and nd a spare-part list for it
at www.honda-engines-eu.com.

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 soil compactor should only be used if it is in a 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 7 soil compactor is designed exclusively for compacting
– sand
– gravel
– crushed rock
– semi-cohesive mixed material
– concrete paving stone.
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.
Operation
Soil compactors are only permitted to be operated by suitable persons of or above the age of
eighteen. Personnel must be instructed in how to guide the compactor by the owner or by the
owner’s assigned personnel.
The machine operator must comply with trafc regulations. If instructions that affect safety are
given by third parties, then the operator must be authorized to reject these instructions.
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.
Unauthorized persons are forbidden from being in the area of the soil compactor during the
compacting process.
Protective equipment includes:
Hearing protection
Hard hat
Safety shoes
Protective gloves

6 CR 7 HD
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 trafc area, the bearing capacity of the ground,
as well as the necessary safeguarding of the construction site in the area adjacent to public trafc;
and it includes compliance with trafc 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.
Always maintain adequate clearance to the edges of pits and embankments.
Do not drive at ninety degrees to slopes to prevent the compactor from tipping over.
After work has been concluded secure the compactor in accordance with statutory regulations,
particularly in the area of public trafc surfaces.
Operation under difcult conditions
Never inhale the exhaust gas; it contains carbon monoxide, a colorless and odorless gas that
is extremely hazardous, which, if inhaled even briey, 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.
Maintenance and repair work
Only use original Weber spare parts to ensure reliable and safe operation for maintenance or repair
work.
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 specied
in this operating and maintenance manual. These activities should only be executed by instructed
personnel.
For repair, service, 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 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.
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 7 HD 7
Inspection
Compactors 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 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 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-specic regulations.
Important information for operating and maintenance personnel is marked by pictograms.

Device description
The CR 7 compactor is used for road building and landscaping compaction tasks.
Drive
The unit is powered by an air-cooled Honda gasoline engine.
Force is transferred to the exciter mechanically via a V-belt.
Operation
Start the Honda gasoline engine with the attached reversing starter.
After starting, vibration is switched on via the centrifugal clutch attached to the engine.
Use the gas lever to vary the engine speed between idle and full throttle.
Forward and reverse is variably controlled via the handle attached to the manual guidance rod.
