1 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.

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.

6 Before Starting

6.1 Transport Before transporting the unit, ensure that it has been unplugged from the power socket. Make sure that it is packed correctly in order to avoid accidental damage.
Be sure to check for any transport damage when unpacking the goods. Note down any damage if found.

6.2 Installation
Open the box, remove the packing materials, and carefully lift out the device and accessories. Check the included accessories. The device has to stand horizontally on a steady and even surface.
Install the device in a place where it will not block the working area and the functionality (take the dimensions into account).
Do not install the unit outdoors or in places without proper ventilation.
Before start-up, be sure the device reaches room temperature.

6.3 Storage
If the unit is to be stored for an extended period, protect it from moisture and dust.

7 Installation/ Start-up
Please remove the safety packing as follows:

Take the pump lever out of the union piece.
Undo the bolt and remove the red safety packing. Insert the lever and secure it
with the bolt.
Screw the ball on the end of the lever.
Centre the cap on the piston to guarantee even pressure distribution.
Bring down the piston on the cap.

The usual pressure is between 2.5 and 5 tones. 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.

8 Operation

8.1 General Operating Instructions

All instructions for using the unit, whether in verbal or written form, are based on our own experience and experimentation and can only be regarded as guidelines.

Prepare cap as per Point 7.
Turn the pressure valve (black knob on housing) to CLOSED.
Now increase pressure with the lever, staying within the permissible zone on the
pressure gauge (green zone).
If necessary, increase the pressure to the maximum, always staying within the
permissible zone on the pressure gauge (green zone).
Once the pressure remains steady, it can be released (valve opened).
Raise the piston and remove the cap.

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.

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.

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.

9 Troubleshooting

Fault

|

Cause

|

Solution

---|---|---

Little or no pressure builds

|

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

|

Vent press as explained below Point 9.1

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

|

Dirty pressure valve

|

Pump strongly with newly filled oil (recommended oil)

9.1 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:
Do not tip the piston
Do not damage the square ring

If the above recommendations do not solve the problem, contact your dental depot or our service department.

10 Care and Maintenance
