Features

The WW-33 hydraulic press, with continuous pressure up to 6 tonnes, presses caps individually and appropriately for the material used. After ending one pressing, it is immediately ready for further use as its solid plastic piston returns automatically once the valve has been opened. A quality pressure gauge which shows the pressure achieved with great accuracy, is recessed into the housing and is thus protected from dirt. The WW-33’s oxidation-free piston (plastic), tensile steel construction (no risk of breaking), and sturdy plastic-coated housing all contribute to the unit’s long service life. As the distance between supports is 152 mm, the press is also suitable for larger caps (IVOCAP) and stirrup pieces. SPECIAL DESIGN: The WW-33 hydraulic press is also available with longer supports for 4 caps.

Applications

With a continuous working pressure of up to 6 tonnes, the WW-33 hydraulic press is used to press caps individually and in accordance with the material used. Only use the device for this type of application.

4

Before you start

4.1 Unpacking / Transport − Open the cartons, remove the packing materials, and carefully lift out the instrument and accessories. Check that the accessories are correct (see 8.4). − When transporting the unit, use appropriate packing materials to avoid accidental damage.

4.2 Set-up/Storage

i

The press must be at room temperature before you use it. − Set the unit up on a flat surface.

− Always ensure that the work area is sufficiently large (take the unit’s dimensions into account). Do not set it up out of doors. − If the unit is to be stored for an extended period, protect it from moisture and dust. − Before you start the press: 1. Take the pump lever out of the union piece. 2. Undo the bolt and remove the safety packing. Insert the lever and secure it with the bolt. 3. Screw the ball on the end of the lever.

5

Start-up

− Centre the cap on the piston to guarantee even pressure distribution. − Bring down the piston on the cap.

i

The usual pressure is between 2.5 and 5 tonnes. This is shown in the green area on the pressure gauge. To avoid damage to the cap and the press, do not pump beyond the zone on the pressure gauge.

6

Operation All instructions for using the unit, whether verbal, written or in the

i

form of practical guidance, are based on individual experience and experimentation and can only be regarded as guidelines.

1.

Prepare cap as per Point 5.

2.

Turn the pressure valve (black knob on housing) to CLOSED.

3.

Now increase pressure with the lever, staying within the permissible zone on the pressure gauge.

4.

If necessary, increase the pressure to the maximum.

5.

Once the pressure remains steady, it can be released (valve opened).

6.

Raise the piston and remove the cap.

-7-

i

The gauge will not be accurate while the pressure is being distributed through the plastic. Full pressure can only be achieved by pumping on the lever several times with appropriate pauses in between. Once the cap is fully enclosed, the pressure remains steady.

i

The return spring on the piston takes it back automatically to its zero position. It has a stroke of about 12 mm. As soon as it reaches this level, it is limited automatically. No more pressure is possible.

i

The oil level should be monitored on the gauge when the piston is down. If necessary, add hydraulic oil. A black vent screw is provided for this purpose. To remove (oil filler nozzle). This is located behind the left-hand support at the top of the housing. No damage can result from overfilling as the surplus oil merely flows out into the nozzle. Note: Use only SHELL TELLUS 32 hydraulic oil.

7

Troubleshooting / Correcting errors

Fault Little or no pressure builds

Likely cause Oil level below minimum and air bubble has entered system during filling

Likely solution Vent press as explained below

Pressure drops to zero despite enclosed cap or piston rises under pressure

Dirty pressure valve

Pump strongly with newly filled oil (recommended oil)

-8-

GUIDELINES FOR VENTING: 1. Turn press on right side and pump. 2. Nothing? – then remove piston as described below and fill with oil up to top edge of cylinder: − Undo set screw in U-piece − Pull lever forwards − Pull piston up and out of cylinder − Fill with oil (recommended oil) − Re-install in reverse order, watching out for two points: a) Do not tip the piston b) Do not damage the square ring

If the above recommendations do not solve the problem, contact

your dental depot or our Service department.

Maintenance

8.1 Cleaning The unit should be cleaned at regular intervals to ensure trouble-free operation. Use normal cleaning products (sponge, soft cloth, mild detergent), but no chemical additives. The piston track should be cleaned daily with a clean linen cloth and then lightly lubricated with the recommended hydraulic oil. The model plate must always be legible and should not be removed.
