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 that 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.
- Break-proof hydraulic press in drawn steel for pressing 1–3 or 2–4 flasks
- Pressure infinitely adjustable up to 6 tonnes
- Rust-proof piston made of super-strong material
- Automatic piston return after the opening of the valve
- Plastic powder coated housing
- Quality pressure gauge with precision display recessed in the housing
- Distance of columns of 152 mm to allow the use of larger flasks and flask clamps
- High stability
- Integrated oil level display

Application
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.
Before Starting
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.
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.
Storage
If the unit is to be stored for an extended period, protect it from moisture and dust.
Installation/ Start-up/ Removing of the Transport Lock!
Before start-up the transport lock* has to be removed as follows:*
Keep the red screw and red bolt for later transport!**
- Unscrew the red sealing screw with an Allen key (not included in delivery) from the vent.
- Remove the supplied pump lever from the column.
- Remove the red bolt by loosening the screw. Insert the pump lever and fix it with the help of the screw.
- 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 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.**
Operation
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.
-
IMPORTANT WARNING:
As a first step remove the transport lock and prepare the 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.
Troubleshooting
Fault | Cause | Solution |
---|---|---|
Little or no pressure builds | Oil level below minimum and air bubble has | |
entered the system during filling | Vent press as explained below in Point 9.1 |
Pressure drops to zero despite the enclosed cap or piston rising under pressure| Dirty pressure valve| Pump strongly with newly filled oil (recommended oil)
Guidelines for Venting:
- Turn press on the right side and pump.
- Nothing? – then remove the piston as described below and fill with oil up to the top edge of the cylinder:
- Undo set screw in U-piece
- Pull lever forwards
- Pull the piston up and out of the 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.
Care and Maintenance
Cleaning
The identification plate has always to be kept in easily legible condition and
has not to be removed.
Remove external dirt from time to time with some form of cold cleaner.
Use only cold cleaners to avoid damaging the paintwork or removing the
lettering.
The equipment should be cleaned at regular intervals to ensure trouble-free
operation.
It requires only normal cleaning (sponge, damp cloth, mild detergent) and no
further chemical additives.
The piston track should be cleaned daily with a clean linen cloth and then
lightly lubricated with the recommended hydraulic oil.
Maintenance
The hydraulic press does not require any servicing. Just make sure that the device is kept clean.
Repairs
Servicing or repairs to the unit have only to be carried out by qualified technicians. Only original spare parts are to be used. Responsibility for the product is voided if unauthorized persons alter it or if inappropriate components are installed.
