Lever Clamping Spot Clamping Lever Absorption Pic. 1: Instructions (Pic. Shows Version 28) SAFETY INSTRUCTIONS Pay attention to the following instructions to avoid malfunction material damages and physical damages 2.1. INTENDED USE The intended use of the unit is the clamping of work pieces with a clamping force of max 25.000 N inside an external absorption.
→ Correct handling and paying attention to the assembly and operating instructions are essential for the productivity reliability and work security. → If the unit shows damages or leakings, it shoud be shut down immediately. → The maximum intendet clamping force is 25 KN, it must not be exceed. Exceedings can leed to serious damage on the unit and physical damages.
CAUTION Slight risk of injury • During transportation, don’t carry the unit on the rubber grommt of the lever. It could loosen and the unit may fall down. • Wear safety clothes and safety equipment while operating hydraulic units. • Wear protective gloves and safety shoes while working with the unit. •...
NOTICE Mounting absorptions are not included in the scope of delivery and should be coordinated individually with the manufacturer. INSTALLATION The lever is split in two parts for smoother handling (Pic. 3). Please use the machined area of coverage on the lever to firmly screw it on to the absorption.

CAUTION 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.
The front absorption on Version 16 and Version 28 is designed rotatable. By turning in any direction, one can switch between two different alignment positions. The alignment is locking 90° shifted. Pic. 5: Illustration 4.1. STRUCTURAL REQUIREMENTS • Prior to installation, make sure that the installation measurements and installation conditions are matching the components of the unit.

CAUTION Obstructions during extending and lowering can lead to squeezing! → Prior to operating the operating lever, make sure no obstructions are blocking the travelling distance. NOTICE Pay attention to clean and dry operating elements while operating the unit. Support area Pump lever Lower lever Pic.
4.3. CLAMPING HYDRAULIC, EXTENDING AND RETRACTING pump ca. 75° pumpen about 75° lower ca. 20° senken approx. 20° Pic. 8: Functional area of the pump lever and lowering lever 4.3.1. EXTENDING Push the pump lever in regular working speed up to the stopper in pumping direction. Max.
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. NOTICE Depending on pressure and stroke, the actuating force during pumping will change.
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. TROUBLESHOOTING DISTURBANCE CAUSE SOLUTION Short-term pressure build Over travel of the overflow Operator tries to create tension with far up only extended piston rod.
FEHLER URSACHE LÖSUNG Unit does not keep Pressure Hydraulic system may Pumping jerkily with open and closed be polluted 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.
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.
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. DANGER Pre stressed spring! Injuries caused by the pre stressed spring unit. →...
DISPOSAL Disposal of the hydraulic and oil Packaging material should be conveyed to an environment friendly recycling. DANGER Pre stressed spring! Injuries caused by the pre stressed spring unit. → Open the unit only if appropriate safety measures are applied to the construction elements.
