→ The manufacturer declares liability exclusion for physical and material damage caused by
incorrect use of the unit.
→ Alterations of the original condition of the unit or self-made repairs will result in expiration
of any warranty.
→ Never work below clamped loads, if additional security measures are not provided. Please regard,
woring below clamed loads is always dangerous even if additional security is applied.
→ Do not repair the unit by yourself, repair work should be done by a qualified technician.
2.3. SECURE HANDLING
→ While using the unit, please check that the piston rod is holohedral and centered effecting the used
absorption and that the alignment points are secured. A outcentered stress can lead to damages on
the unit and danger to individuals.
→ While retracting the piston rod, the operator and other persons must stay out of the danger zone.
→ Pay attention to the warning instructions of the manufacturer.
→ The unit should be operated by people trained in the use of the unit only .

Danger of physical damage, caused by oil spillage
Danger of physical damage, caused by loosened lever
• Don’t drill additional holes in to the unit to install additional absorptions!
• Wear safety glasses to avoid eye injuries!
• The hand lever is moving. Pay attention when mounting the unit to avoid
squeezing of skin parts.

4.3. CLAMPING HYDRAULIC, EXTENDING AND RETRACTING
Pic. 8: Functional area of the pump lever and lowering lever
4.3.1. EXTENDING
1. Push the pump lever in regular working speed up to the stopper in pumping direction.
Max. 75° (Pic. 8)
The piston rod executes a stroke movement. According to the travelled angle area, it will
lead to the max. stroke or proportionate smaller.
The possible pump area is limited by a stopper. Quit pumping on arriving at the stopper.
The pump lever is repressed by spring force in to the initial position. Relieve the lever.
The pumping chamber will be filled anew. The unit is ready for a new stroke movement.
According to the travelled angle area in the back movement the following possible stroke
movement will be up to the maximum stroke, or respectively shorter.
2. Ending the pump movement will result in ending the stroke drive. The position of the piston
rod will not change.

3. With reaching the upper stop position, no additional pressure will build up. The force on the
pump lever stays unchanged. The piston rod may move a little over the end position and will
then lower just about 2 mm. This is a normal operating condition.
The unit is in any positon (360°) applicable, utilizing the complete stroke length.
Should an angle or construction part on which you put pressure with the table press bend
more than 4 mm please stop putting on pressure.
NOTICE
Depending on pressure and stroke, the actuating force during pumping will change.
Adapt your working speed to the necessary power and your physical condition.
4.3.2.RETRACTING
When actuating the lowering lever, the unit will retract by spring return without actuation force.
1. Retracting and release of the work piece will be activated by pushing the lowering lever (Pic. 5).
There will be a release valve opened and the oil flows from the pressure chamber back to the
tank room. The unit lowers while the piston rod reverses.
2. When you release the lowering lever and turn the lever back, the lowering movement will stop.
The release of the lowering lever is activated by an integrated spring. The lowering movement
will end immediately, the piston rod stays in its current position.
Retracting is also position independent possible.
CAUTION
Physical damage trough sliding or squeezing danger
• Squeezing danger: While lowering, the piston rod will retract to the stopper.
Your hand and/or parts of your skin may be squeezed in.

CAUTION
Obstructions during extending and lowering can lead to squeezing!
Squeezing danger: During lowering the piston rod will accelerate by applied forces.
High force and high speed can develop.
5. TROUBLESHOOTING
DISTURBANCE CAUSE SOLUTION
Short-term pressure build
up only
Over travel of the overflow Operator tries to create tension with far
extended piston rod.
Max. stroke reached The overflow is over traveled during
pressure build up. This results in an
immediate pressure loss. The piston
rod travels the length of the excess
to the overflow back, about 2 mm.
Pressure will not build up Safety valve is responding Ensure intended use!
Hydraulic unit polluted Keep the lowering valve open and try
pumping several times.
Repeat this procedure several times.
Pumping jerkily with open and closed
lowering valve. Produce strong internal
oil flow to flush pollutants of the valve
seating.
Repeat this procedure several times.
Unit does not hold the
pressure
Drain valve not fully closed Check drain valve if contamination
prevents complete closing.

FEHLER URSACHE LÖSUNG
Unit does not keep Pressure Hydraulic system may
be polluted
Pumping jerkily with open and closed
lowering valve. Produce strong internal
oil flow to flush pollutants of the valve
seating.
Repeat this procedure several times.
Temperature fluctuations The unit is a closed system which is
acting to temperature fluctuations
because of its tightness.
While cooling down (overnight, par
example) the clamping pressure may
change. The work piece may loosen!
This is not a default of the unit!
Keep the surrounding temperature
constant.
Piston rod is bucking,
hardly retracting
Attachment parts may be
to heavy
The spring force is strongest at maxi-
mum stroke and declines at reduced
stroke accordingly. Reduce the weight
of the attachments.
Polluted piston rod Clean the piston rod.
Piston rod does not extend Safety valve is responding Maximum clamping pressure reached
No stroke without load Bursting element responding
See chapter 5.1
5.1. SAFETY VERSUS OVERLOAD
The unit is fitted with two systems safeguarding overload caused by excessive hydraulic pressure.
SYSTEM 1
Pressure safety with pressure control valve (DBV)
The pressure control valve secures the unit against excessive pressure, which is applied from the
operator with the hand grip. The DBV opens and prevents an excessive hydraulic pressure inside
the unit.
The DBV is closing automatically responding to relevant lower pressure. The unit stays functional.
17

SYSTEM 2
Pressure safety with bursting element
Bursting elements are pressure protections which secure pressure leading systems against dangerous
excess pressure. It occurs in bursting of a bursting disc, which is consisting of metal foil.
In case of the acting of an external force to the piston rod, by example an additional hydraulic,
an excessive distortion of the work piece, the pressure safety will be destroyed.
The bursting disc is responding to a force of 36000 N axial to the piston rod. The piston rod retracts
according to the effecting load completely and stays functional.
For replacement, please contact your distributor.
CAUTION
Manipulation on the safety valve!
→ The unit is on the side of the piston rod and on the pump piston side secured against
over loading through a safety valve. Manipulation may lead to damages on the unit
and/or physical damages to people.
6. MAINTENANCE AND REVISION
6.1. MAINTENANCE
The unit is basically maintenance free.
CAUTION
When leaking fluids, there is an increased fire hazard and an increased danger
of slipping!
→ Check the unit leak tightness prior to each utilization.
→ By noticing abnormalities, don’t utilize the unit and contact your distributor.
→ Check the unit about damages and defects.
→ Don’t use a damaged product.
→ Check the optical condition of the coating and the existing of the operating elements.
18

DANGER
Pre stressed spring!
Injuries caused by the pre stressed spring unit.
→Never open the unit without appropriate protection!
NOTICE
Damage of the unit trough self-repair!
→ Contact your distributor in case of repair.
→ Order spare parts through you distributor only.
→ Retain a specialist, trained on this unit.
NOTICE
This hydraulic unit is a closed system, there is no additional maintenance
required.
→ The unit doesn’t possess an oil filling screw.
→ The oil level cannot be checked .
NOTICE
→ Because of the aging effect of the seal material, the seals should be replaced
every 6 years.
→ Contact your distributor.
→ Do not open any screw on the unit for checking or refilling oil.
Replacement of the seals
Hydraulic fluids are predominantly inflammable. In case of leaking of the unit and contact of the fluid to
open fire or hot surfaces it can ignite.
Make sure that initial fire can be extinguished with a suitable extinguishing agent.
→ Suitable extinguishing agent: Foam, extinguishing powder, carbon dioxide, sand, water fog
→ Non suitable extinguishing agent (safety reason): Waterjet
