 GENERAL DRAWING

1. BEFORE USING THE EQUIPMENT

Upon removing the protective packaging from the crane, carefully inspect it. Check for: Oil leaks, signs of corrosion; damage to the hydraulic cylinder, line, frame and

the hydraulic attachments to the frame, and incorrectly assembled accessories. If you find any damage or fault with the product, clearly label it and place it in a location

where it will not be available for use until an authorized service dealer has repaired the fault.

Never use hydraulic equipment that is damaged or suspected to be in poor condition.

Familiarize yourself and your co-workers with the equipment. Before you begin using the jack, carefully read and observe all instructions and

recommendations enclosed in the packaging. Your negligence in this matter may cause personal injury or material damage.

Do not loose the instruction manual.

Do not operate hydraulic equipment near open flame, explosives, and sources of intense heat or any other hazard, which could cause a fire or the damage equipment

The hydraulic equipment should not be exposed to temperatures grater than 60ºC when in use or when stored.

If purchasing just a cylinder or pump for use in a press, ensure that you are using the proper combination of pump, cylinder and press frame before

assembling the unit. We recommend you seek professional advice on the matter.

When choosing a place for the press, ensure that it will be located over firm, level ground such that the entire base of the press contacts the ground. If any doubt exists

as to whether the ground will able to support the press and the additional weight it will see when in use, distribute the weight over a larger area by placing rigid steel

beams or planks under the base of the press. Store the press with the cylinder’s piston fully retracted.

We recommend you wrap the cylinder in a protective plastic or place it in a location free of dirt, dust, steel shavings and other foreign matter, which can enter into the

cylinder and damage its components.

2. TECHNICAL FEATURES

3. ESSENTIAL SAFETY REQUIREMENTS

DANGEROUS AREA

Due to the FUNCTIONAL REASONS it is considered to be the space between the columns, the bed and the hydraulic cylinder piston.

Due to the MATERIAL PRESSED it is supposed to be surrounding area to the machine in case of metal parts being ejected during pressing.

The speed of the hydraulic cylinder during its extension is less than 30 mm/second. Therefore, then machine should be considered by the application of ANNEX V of

the Declaration of CE Conformity. Operators standing in the dangerous area around the machine should protect their feet, faces and hands from metal pieces being

ejected during pressing.

Feet protection Face protection Hands protection

Used materials and components are not for the health and safety of operators. The hand pump contains LARZEP hydraulic oil ISO: HV46.

HIDRAULIC OIL IS TOXIC IF IT ENTERS THE BLOODS STREAM. NEVER PLACE A FINGER OVER ANY ORIFICE OR LEAK, WHICH COULD

BE PRESSURIZED, SUCH AS THE HYDRAULIC LINE, AS THIS COULD CAUSE OIL TO BE INJECTED INTO BLOOD STREAM.

 In order to start the equipment is necessary to connect the pump to the cylinder.

 The cylinder movements are made when we act the lever of the pump.

 When we pump, the cylinder will moves forward, and when we open the release screw of the pump, the cylinder will return.

 To stop the cylinder advance, stop handling the lever of the pump. For a new start up, it will be necessary act the lever again.

 The construction of machine has been calculated to bear without any breaking under conditions of foreseen utilization and for the whole life of the machine.

The hydraulic components have been designed and calculated in compliance with the ANSI B30.1, and have been proved to 875 kg/cm2 of pressing.

 The frame of the machine does not cause to be dangerous in that sense.

RISKS DUE TO HYDRAULIC ENERGY: The pump is equipped with an internal security valve in the tank, out of operator’s control and rated at 700 kg/ cm2

 All the maintenance operations must be performed while the machine is stopped avoiding this way any potentially dangerous situation. A poor maintenance

program of the press does not increase the risk, but obviously will revert in a lower performance.

 The hydraulic pump is mounted out of the frame and access is very easy. To disassemble the pump, unscrew the cover screws. In order to disassemble the

cylinder it is required first to disassemble the hoses and this from the frame.

ISOLATION OF THE POWER SUPPLY: Disconnect the rapid coupler from the pump.

INFORMATION DEVICES: In the pump: Oil level and oil filling tap. In the cylinder: A gauge in order to know the operating pressure anytime.

The press, the cylinder and the pump have their corresponding serial numbers marked on them. In addition to it, you can find a sticker label showing the commercial

reference, capacity, working pressure, name and address of the manufacturer.

4. TRANSPORT AND INSTALLATION

The machine is delivered properly packed in a wooden ballet. For it’s handling, it is recommended to use a forklift truck or a crane. In the last case, it is necessary to

make the slings trespass the arc of the frame. When doing this operation, you should be cautious and prevent the flexible hoses and couplings from any damage.

The machine is stable enough to operate without fixing, but if is placed in an area commonly operated by mobile machinery (cranes, lifting equipment…) it is

strongly recommended to fix it to the desired place by drilling the supporting plates.

HYDRAULIC CONNECTION: Release the plug of the coupler; in the cylinder, and connect the hose, screwing the rapid coupler to the limit with the hand.

INSTALLING THE GAUGE

1- Replace the threaded tap in the top of the cylinder by the gauge, which is supplied separately.

2- Tighten the gauge cone to the gauge adaptor seat by using a flan wrench size 22.

3- Hold the gauge screen by hand during threading process and after reaching a comfortable reading position set the gauge screen free so that it turns the last quarter

solidarity with the thread.

CHECKING THE RIGHT OPERATION OF ALL DEVICES AND MECHANISM

Select the working maximum pressure. In manual presses 700 kg/cm2. With the hand on the lever, pump several times and check the cylinder advances.

Open the release screw of the pump and check that the cylinder piston returns by the internal spring.

To retract or stop the cylinder is necessary let the lever without movement.

Without put anything in the press, repeat the advance movement, until reaching the cylinder full stroke. In that moment the pressure will start to be increased and we

can observe it now in the gauge. This pressure will go on increasing until reaching the installation maximum pressure, previously chosen. In this stage, the cylinder

maintains the reached pressure, (the gauge maintains the reading). Check there are no leaks in the installation (gauge intake, couple, etc.)

To retract the cylinder and eliminate the installation pressure, open the release screw to the left. The piston returns by the internal spring. The return may be slower at

the end of the backstroke. Put the material to be treated in the press and act as explained regarding all the safety rules.

5. MAINTENANCE

The hydraulic circuit of the press is closed, so in normal conditions no oil leakage should be coming up. In case of oil leakage, after the proper repairing work, you

should fill up the tank with hydraulic oil by LARZEP (Ref. AZ8901); the pump is equipped with an oil level indicator to control the need quantity of oil.

As far as a non-continuous use of the press is concerned (1 hour per day), oil replacement should be done once a year.

To empty the tank, you should remove the cover and take the oil out to another container. Please, bear in mind the existing rules for waste processing when handling

the used oil. Keep greasy and lubricated the pin bearings, the piston and in general all the parts that might be in friction.

USE ONLY LARZEP HYDRAULIC OIL. Other grades of oils or types of hydraulic fluid (such as brake fluid) may affect the performance of the equipment or cause

the deterioration of the seals.

DO NO ATTEMPT TO FILL THE PUMP WITH OIL WHILE IT IS CONNECTED TO A CYLINDER WHICH IS SUSTAINING A LOAD BECAUSE IT

MAY OVERPRESSURIZE THE RESERVOIR WHEN THE PISTON RETRACS AND CAUSE DAMAGE OR INJURY

Always use the original LARZEP parts to prolong the service life of your hydraulic equipment. LARZEP S.A. or your authorized dealer can supply you with original

parts for simple maintenance work.
