GENERAL
1. GENERAL
This manual contains general information about assembly, installation, operation
and maintenance of the DYNASET HVB Hydraulic Vibration Pump and DYNASET
HVD Hydraulic Directional Vibra.
ATTENTION!
Read this user manual before installation, use or maintenance of the HVB
and HVD to ensure proper handling, operation and maintenance right
from the beginning. Pay attention to warnings and safety instructions.
READ CHAPTER ”2. SAFETY” for more information.
1.1. PRODUCT INFORMATION
DYNASET HVB Hydraulic Vibration Pump is connected to the base machines
hydraulic cylinder that operates the tool e.g. bucket. Activating HVB it creates
fast back-forth movement to the cylinder resulting vibration to the tool. HVBs can
create up to 30 Hz vibration. The Vibration power depends on the cylinders max.
power. HVB is a great for enhancing bucket emptying, increasing frozen ground
penetration, soil compacting and pile driving.
DYNASET HVD Hydraulic Directional Vibra is installed straigth to the tool e.g. to a
bucket. HVDs produce powerful directional vibration for buckets, street cleaning
units, soil compacting etc. HVD vibras create up to 70kN power with 35 Hz
frequence.

2. SAFETY
2.1. SAFETY PRECAUTIONS
ATTENTION!
Operators and maintenance personnel must always comply with local
safety regulations and precautions in order to close out the possibility of
damages and accidents.
The pressure in hydraulic circuit of HVB and HVD is considerably high.The technical
condition of your equipment and hydraulic system should be under constant
observation.
WARNING
HIGH PRESSURE OIL!
Can cause severe injuries.
Always wear appropriate clothing
and safety equipment.
Couplings, valves and hoses should be maintained tight and clean to avoid
possible leakages of pressure and hot blowouts. Hydraulic leakages must be
rectified immediately to avoid user and bystander injuries.
In order to avoid possible accidents, it is not allowed to clean or inspect HVB or
HVD unit when hydraulic circuit is pressurized. Prior to any cleaning, inspection
and service, hydraulic system of your base machine must be stopped and hydraulic
circuit must be depressurized.
2.2. SAFETY EQUIPMENT
Always wear appropriate clothing and safety equipment such as safety goggles,
safety shoes and ear protection when operating the HVB or HVD unit.

SAFETY
2.3. OPERATING SAFETY
When operating the HVB or HVD unit, beware of machinery parts warmed by hot
hydraulic oil.
WARNING
RISK OF BURNS!
Parts of the unit, oil, and oil filler cap
can be hotter than 80 °C!
Wear personal safety equipment!
ATTENTION!
Do not exceed the maximum pressure, temperature and load.
2.4. MAINTENANCE SAFETY
ATTENTION
Installation and service of hydraulic equipment must be performed by
qualified and experienced personnel only.
NOTE!
When carrying out any maintenance to HVB or HVD unit, keep the
components of the system clean. This is important to ensure safe, reliable
and longlife operation of your equipment.
Hydraulic system of a base machine should be maintained according to the service
program.

OPERATING INSTRUCTIONS
3. OPERATING PRINCIPLES
3.1. OPERATING DESCRIPTION
HVB
HVB hydraulic Vibration Pump increases and decreases the pressure in cylinders A
and B lines creating a small fast pace movement, vibration.
Picture 8: Operating description of HVB
When the hydraulic flow is opened to the HVB (1) it starts to create pressure to one
of the cylinders hydraulic lines. At the same time the HVB decreases the pressure
same amount from the other cylinders hydraulic line.
The patented pump structure of HVB reverses piston movement when the piston
reaches the peak point and the pressure direction turns to opposite. This way the
cylinder moves back and forth (2) safely creating vibration to the tool it is attached.

OPERATING INSTRUCTIONS
HVD
HVD Hydraulic directional vibra creates directional movement straight to the tool
e.g. bucket.
Picture 9: Operating description of HVD
When the hydraulic flow is opened to the HVD (1) the patented cylinder design
starts to move back and forth creating directional vibration to the tool (2).
