1.12 Safety devices

COMBI 3000 was designed in line with safety standards establishedat a European level and ratified in Italy with D.P.R 459-96.The safetydevices, as per machine directive98/37/CE, were designed with utmostimportance given to the safety of the operator.Safety and accessibility are combined perfectly in COMBI 3000; theoperator is fully protected, without any risks.1.12.1 Guards and safety devices.

The machine is fitted with fixed guards secured with fixing crews andguards which prevent access to the moving and dangerous parts. Allthe fixed guards, covers and screens secured with screws havebeen designed to protect the operators (maintenance personnel,technicians, etc.) from injuries caused by electrical discharges andmoving mechanical parts.Therefore, there is no envisaged use of the machine where theguardshave been modified or removed from the positions which they havebeen designed for.

Before carrying out any machine maintenance or repairs, themachine must be turned off at the mains switch and the mainsplug must be disconnected so that nobody can turn on themachine using the mains switch.

2 MACHINE INSTALLATION

2.1 Lifting and unloadingCombi 3000 has been fitted with suitable lifting brackets. The machinecan be lifted with a crane (Fig. 2.1/A) or a forklift truck (Fig. 2.1/B).

Always check that the resistance of the cable and thecapacity of the crane/forklift truck are of sufficient size forthe purpose, checking the weight of the machine on theappropriate metal plate on the machine (Fig.1.1-A).

2.2 PositioningPut the machine in the most suitable position, bearing in mind theelectrical connections. The space required for use and maintenanceis shown in the diagram below (Fig.1.2).

Always disconnect the power supply plug before moving themachine.

During installation, ensure that the legs are perfectly level on thefloor of the building site to guarantee machine stability

2.3Connecting the machine to the mains power supply

Check that the mains power supply unit to which the machine isconnected has an earth connection as envisaged by currentstandards, and that the socket is operating correctly.

Remember that there must be an overload protection upstream ofthe mains power supply unit which can guarantee the safety ofall the conductors from short circuiting and overload.

- Ensure that the electric line has a differentialoverload switch upstream. Use, if necessary, the IMERrapid coupling differential safety device (RCD), availablein kit form (cod. 1169245).Check that the power supply voltage is correct for machineconnection: 230 VOLT 60 Hz single-phase.

- Connection to a power supply unit conforming toCEI- 64-8 standards (standardisation document CENELEC

HD384).The electric power supply line must be sufficient to preventvoltage drops. In particular, cable drums (with collector rings)must not be used.The dimensions of the conductor must be based on the startingcurrent and the length of the line. As per regulations, a 4x4 mm²conductor is sufficient, up to 50 m. After installation it is stillnecessary to measure the voltage, with the load, both for startup and functioning. During functioning, voltage drop must belimited to 5%. If using longer conductors or a mains which is notoptimal, use cable with a section of at least 6 mm².The power supply cable used in the building site must be fireresistant and have a suitable outer sheath, resistant tosquashing, wear and atmospheric agents.

- The machine must be connected to theequipotential earth unit in the building site. Theconnection point is the screw marked with a plate and anearth symbol

The section of the earth cable, which is yellow-green, shouldbe the same as the section of the line conductors or at leastconform with current legislation and technical standards inthe country in which the machine is used.

Before making the connection, check that the mains voltage and frequency correspond to the machine specifications.

(See machine identification plate).

The power supply lines in the work area must be positionedto ensure that they are not damaged and that water does notpenetrate the collectors. Only use collectors and attachmentsfitted with water jet protections. Do not place the machine onthe power supply lines. Suitable protection must be adopted.

Do not use a temporary machine connection, the operationmust be carried out by specialised personnel. Ensure thatthe attachment for the power supply cable in the plug-switchunit housing is stable.

The work area must respect accident prevention and securitydevice standards.

2.3.2 Main requirements of the electrical cabinets.

The functioning principle of the electrical cabinets envisages adifferential switch for starting the cutting unit and a switch forthe transfer unit. If there is a voltage drop, the rotation andtransfer motors stop; when the voltage returns, the motor doesnot start again until the reset push-button is pressed.The electrical cabinet is positioned on right hand side of themachine to guarantee that the operator has easy access to thecontrols.

2.3.3 Main requirements of the electrical motors.

2.4 Machine noise level.

2.4.1 Introduction

The values given for the noise are emission levels and notnecessarily safe work levels. While there is a correlation betweenthe emission levels and the exposure levels, this cannot be usedas a reliable indicator to establish if further precautions arerequired or not. The factors which influence the real level ofexposure for the worker include the duration of the exposure,the environmental characteristics and other noise sources, forexample, the number of machines and adjacent work areas. Theexposure levels permitted can also vary from country to country.However, the following information enables the user to make abetter estimation of the dangers and risks.

- Prolonged exposure to noise above 85 dB(A) maydamage health. It is therefore recommended thatappropriate protection measures (e.g. ear muffs, plugsetc.) are taken.

3 MACHINE USE

3.1 General description

Once the machine installation has been completed, machiningcan begin.COMBI 3000 consists of a stainless steel cutting surface. The 3kW motor and the work head are fitted on a pre-stressed steelbar with high mechanical resistance. The bar, together with thework head, can be tilted for 45 degree cutting. The operating unitis driven by a transfer unit connected to the cutting unit. Themachine is fitted with a mobile tank. The cooling pump immersedin the tank guarantees lubrication of the disk during the cuttingphase.COMBI 3000 can be used for 90 degree vertical cutting and 45degree tilted cutting.For vertical cutting, the pieces must have a maximum length of3000 mm and a maximum thickness of 100 mm. For 45 degreetilted cutting, the pieces must have a maximum length of 3000 mmand a maximum thickness of 45 mm.The machine consists of a mobile cutting part (Fig.3.1-A), a fixedmachine support frame (Fig.3.1-B), a disk cooling tank (Fig.3.1-I)and an adjustment unit (Fig.3.1-D).The machine is fitted with protection devices to guaranteemaximum functioning safety. There is a emergency stop switchon the electric cabinet. (Fig.4.2-D).

3.2 Functioning

COMBI 3000 functions as follows:

1. The piece to be machined is placed against the end stop (Fig.3.1-H) of the work surface with the required tilt using theprotractor (Fig.3.1-D).

Place the piece firmly against the end stop (Fig.3.1-H). If necessary, for long pieces, use the blocking tool (Fig. 5.5) for stopping the pieces on the cutting table by pushing the handle (Fig.5.5 ref. 2). The blocking tool can be used both at the beginning side of Combi 3000 at the end side of the main frame.

2. To select 45 degree tilt cutting, it is sufficient to release theappropriate blocking knob (Fig.3.1-G) and tilt the operatingunit using the manual pump (Fig.3.1-L). Then secure theblocking knob again. Check that the blocking handles(Fig.3.1G) are tightened before starting to machine.

Ensure that the disk is suitable for the material being cut.

Ensure that the cooling liquid tank is full.

3. Start up the pump by turning the control (Fig.4.2-L) to ON andwait until the water wets the disk.

4. Check the position of the disk compared to the cutting lineand, after positioning the piece, perform the followingoperations: A. Start up the disk by pressing the push-button (Fig.4.2-O). B. Check the rotation direction of the disk compared tothe indications on the guard. C. Start the cut using the lever (Fig.4.2-M).

5. The cut must be performed by moving towards the check endstops on the cutting surface.

6. The cutting infeed speed must be adjusted in relation to theeight and type of material to be cut to avoid overloading themotor, using the relative control (Fig.4.2-F/H). The cuttingspeed is adjusted by checking, during the work phase, themotor absorption, which can be read on the amperometer(Fig.4.2-B). High absorption values correspond to high cuttingpressure which can be reduced by turning the knob (Fig.4.2-F) to reduce the disk infeed speed. The return stroke time for the cutting unit can be reduced byturning the knob (Fig.4.2-H) to increase the transfer speed.

3.3 Operating unit

The operating unit consists of the following:

1. A sliding unit guided by wheels on bearings (Fig.3.2-A).2. A reducer motor for unit transfer (Fig.3.2-C).3. A cutting motor which drives the grinding disk (Fig.3.2-D).4. A grinding disk guard (Fig.3.2-B).5. A handle for vertical positioning of the disk (Fig.3.2-E).

3.4 Machine use

For correct machine use, we recommend that the user followsthese important procedures:1. Leave a minimum of 60 cm of free space around the machine

for safety reasons.2. Do not allow unauthorised persons to approach the machine

during cutting.3. Do not use the machine in areas where there is a risk of fire

as sparks may cause fires or explosions.4. Always turn off the power supply before positioning and

moving the machine.5. Always ensure that the disk is not in contact with anything

before starting up the motor.6. Check that the guards are all in the correct position.7. Check that the rotation direction of the disk is the same as that

indicated on the guard.8. Before starting to machine, fill the water tank. Check and, if

necessary, top up the level of water during use: the pumpsuction head must always be immersed.

- It is absolutely forbidden to create unnecessarysafety risks, by removing the machine guards.

9. All the disk adjustments must be made with the motor turnedoff.
