Safety guidelines
General
All safety instructions must be read and complied with, as non-compliance will result 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 tamper should only be used if it is in a technically faultless condition, as intended, in a safety-
conscious and hazard-conscious manner, and in compliance with the instructions in the operating
manual. Malfunctions that impair safety must be eliminated without delay.
The tamper is designed exclusively for compacting
– sand,
– gravel,
– crushed rock,
– semi-cohesive mixed material.
Any other use of the tamper 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
Tampers are only permitted to be operated by suitable persons of or above the age of eighteen.
Operators must be instructed in how to guide the tamper by the owner or by owner’s assigned
personnel.
The machine operator must comply with tra󰀩c regulations. If instructions that a󰀨ect safety are given
by third parties, then the operator must be authorized to reject these instructions.
Unauthorized persons are not allowed 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:
Hearing protection
Hard hat
Safety shoes
Protective gloves

The tamper described in this operating manual is suitable for use in trenches that are deeper
than shoulder height, provided the following basic conditions have been met:
– Trench width at least 1.5 m
– Trench depth no more than 3.0 m
– Open trench width at least 10 m
– Slight wind movement in the trench
– The compactor is used for periods of no more than 4 x 15 minutes per shift,
interrupted by breaks (each approx. 1 hour)
If these boundary conditions are not complied with, the owner is required to implement the protective
measures identied as necessary to avoid CO poisoning as part of the owner’s risk assessment,
for example:
– Use of zero-emission compacting equipment
– Blower-supported ventilation with a fan forcing air along the length of trench
The use of respiratory equipment during operation of this gasoline-powered compactor without docu-
mented evidence of conformity and without the necessary precautions is generally not permitted!
– As CO will accumulate in the blood after repeated use
– As CO lters have a short service life
Operation
Prior to starting work the owner of the tamper must be familiar with the work environment. The work
environment includes obstacles in the work and tra󰀩c area, the bearing capacity of the ground,
as well as the necessary safeguarding of the construction site in the area adjacent to public tra󰀩c;
and it includes compliance with tra󰀩c regulations.
The tamper 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 tamper must be checked for apparent defects. If there are apparent
defects, operation of the tamper must be stopped immediately, and the responsible person
must be informed. Prior to restarting, tamper malfunctions that have occurred must be corrected.
Operation under di󰀩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, covered pits, etc.).
Exercise particular caution when operating the engine in the vicinity of people and livestock.

7
Maintenance and repair work
Only use original Weber MT spare parts to ensure reliable and safe operation for maintenance or
repair work.
Adjusting tasks, maintenance tasks, and inspection tasks must be carried out on schedule as
specied in this operating and maintenance manual. These activities should only be executed
by instructed personnel.
For repair, maintenance, or inspection work the engine of the tamper 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 tamper 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.
If lubricating oils and fuel come into contact with skin, they can cause skin cancer. Upon contact
with the skin, clean a󰀨ected skin with suitable cleaning agent without delay.

8
Inspection
Tampers 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 at least until the next inspection.
Cleaning work
Prior to cleaning the tamper 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-specic regulations.

Device description
The series SRV 620 tamper is used for road-building, canal construction, pipe laying and landscaping
compaction tasks.
Drive
The tamper is powered by an air-cooled Honda gasoline engine.
Force is transmitted via the centrifugal clutch directly to the tamping system. The compaction work is
performed by the tamping foot.
The engine is protected by a double lter system consisting of an oversized main air lter and an
additional air lter.
Operation
Start the Honda gasoline engine with the attached reversing starter.
After starting, the tamping system starts to vibrate via the centrifugal clutch which is attached to
the engine. Use the gas lever to vary the engine speed between idle speed and full-throttle speed.
For easier transport the tamper can be pushed onto or into a means of transport with the help of
the transport roller.
