1 For your safety
1.1
Correct use of this product

noted.
-5-
1.3
Safety guidelines
Servicing and repairs should be carried out only by authorised specialists.
Before you carry out any cleaning or maintenance work, disconnect the
power plug and prevent the motor from restarting accidentally. You should
!
also disconnect the water line.
Always wear eye protection when working on grinding wheels.

incorrectly, used for other than their intended purpose or inadequately
serviced.
Only qualified specialists should carry out work on the motor.
!
Condensers must be allowed to discharge completely before you open the
unit.
When working on the unit, wear close-fitting garments and roll sleeves
!
inwards only. Do not wear gloves.
If you have long hair, wear some form of protection such as a hair net.
When working with the HSS-AZ, do not wear rings, chains, bracelets or
similar jewellery.
i
Be sure to shut off the tap at night and over the weekend.

1.4
Potential dangers
!
1.5
The trimmer’s rotating parts and the grinding blade are dangerous.
Your user manual
Configuring and operating this equipment requires precise knowledge and observance
of the instructions in this user manual. The equipment is designed only for its intended
application.
1.6
Responsibility for operation and damage
The responsibility for operating the unit lies exclusively with the owner or user if the said
unit is incorrectly serviced, maintained or altered by persons not employed by an
accredited dealer or if the unit is used in a manner contrary to its specified purpose.
The unit must be maintained and operated in accordance with this user manual.
Wassermann Dental-Maschinen GmbH is not responsible for damage arising from the
non-observance of these instructions.
Guarantee and responsibility provisions contained in the sales and supply conditions of
Wassermann Dental-Maschinen GmbH are not extended by these instructions.
Product responsibility lapses if the equipment is altered by third
!
parties or if non-original parts are installed. Use only original
Wassermann replacement parts. If damage occurs after a “foreign
wheel” has been installed, responsibility lies with the person who
installed said replacement wheel.
If diamond-grinding wheels are used, they will exhibit extreme wear if
you grind embedding materials and metals. Wassermann assumes
no responsibility in such cases.

1.7
Authorized users
The owner of the equipment must ensure that any users have been provided with the
user manual and that they have read and understood its contents before operating the
equipment.
i
Ensure that this user manual is accessible at all times and has been
read and understood.
2 Care and maintenance
2.1
Maintenance
Before you carry out any cleaning or maintenance work, disconnect
!
the power plug and prevent the motor from restarting accidentally.
Be sure to disconnect the water supply when carrying out this work.
Do not open the unit until the grinding wheel has come to a complete
stop.
The HSS-AZ plaster model trimmer does not require any maintenance. However, if you
open the wheel chamber for cleaning or to change the wheel, be sure to clean the
sealing surfaces and coat them with a new application of water-insoluble grease (Top
2000).
For safety reasons, you should regularly check that the clamps on the water hose are
tight.
-8-
2.2
Care
i
We recommend removing any caustic traces of plaster from the
outside of the unit from time to time using a damp cloth. The HSS-AZ
does not require any other care.
3 Use/Application
The HSS-AZ trimmer is used for grinding (trimming) plaster models.
*** Use this equipment only for its intended purpose! ***

Set-up and storage
When you set up the unit, make sure that the grinding wheel is accessible and that
the unit is close to the plaster cutter.
-
You will need the high-pressure hose with the woven insert and a diameter of 1/2
inch (13 mm) when installing the rinsing water hose. You use the plastic hose with a
diameter of 1 inch (25 mm) for the drain hose.
-
When it comes to functional safety, the location of the trimmer is very important,
even if it is only to be stored there for a short period. The location should be dry, well
ventilated and free of vibration. An even temperature and a wooden base are
desirable. The trimmer must not be set up or stored out of doors.
i
Warning!!! The trimmer must be at room temperature before you start
it.

We reserve the right to make technical changes.
The noise emission measured in a 1-metre circle around the unit and 1.6
metres high at an average 50% idling, 30% average load and 20% full load
was 69 dB(A). This was determined in accordance with DIN 45635 Part 1.
i
After you switch the trimmer on, wait a few seconds for the motor to
come up to speed. Only then can you use its full power.
Never push on the models so hard that the motor labours. This could
overload it and cause possible damage.
- 11 -
5.2
Water regulation
The water supply is regulated at the tap. The flow of water is sufficient if the grinding
wheel is close to its natural colour when grinding.
When grinding, use light pressure only and do not move the model to the right or left.
i
You should, of course, always work with fully set plaster models, as
wet plaster can cause blockages, especially in drain hoses.
6 Installation
6.1
Location
Because the trimmer operates exclusively with water, we recommend you install it close
to a tap. The best place is right next to a washbasin or, using the wall mount, directly
above the basin.
- 12 -
6.2
Rinsing water hose
Locate the rinsing water hose (thinner hose with woven insert) between the tap and the
hose connector on the trimmer. This connector is at the rear, under the motor. Use the
clamps already on the hose to connect it, tightening them securely.
There should be a stopcock between the tap and the feed hose so the hose is not under
continuous pressure when the trimmer is not being used.
Tighten the hose clamps again about 2 days after installation.
i
The tap must be turned off at night and over the weekend.
6.3
Drain hose
The drain hose must be laid out such that water can never back up in the trimmer. This
would cause the water to spray out through the grinding wheel opening. Always arrange
the hose in a smooth bend (not kinked) and with a permanent drop of at least 1 cm per
metre.
i
The end of the drain hose must be above the water level of a plaster
catcher.
The hose end must not be immersed in the water.
- 13 -
In its standard configuration, the drain-hose connection is angled off to the right.
However, it can also be aligned vertically to the right, and this is recommended in
difficult drain situations.
In that case, use a sealing cap instead of the drain connection.
7 Assembly
7.1
Installing the angled mount
The angled mount is inserted as required in the HSS-AZ support plate. Please follow
the guidelines below.
i
When working with the angled mount, make sure that it has been
installed correctly. It should be installed as shown in the diagram
below.
Make sure that items 1 and 2 are
inserted correctly in the support plate.
- 14 -
8 Supports
The HSS-AZ plaster trimmer does not need any other support than the one described in
7.1 Installing the angled mount.
9 Maintenance
9.1
Servicing
For details of maintenance, see 2.1 Maintenance. Otherwise, the trimmer does not
require any special maintenance.
9.2
Troubleshooting
Fault
Water spray at
wheel opening
Likely cause
Water supply set too high
Drain hose has been
lengthened with a thinner
hose
Drain hose is kinked
Hose end is under the
surface of the water in the
plaster catcher
The fall of the hose is
insufficient
The radius of the hose is too
small
There is a tube bend in the
hose (causing blow-back)
Likely solution
Reduce water pressure at tap
or ball valve (see 5.2 Water
regulation)
Make sure that the diameter of
the drain hose is 1 inch (25.4
mm)
Make sure the hose is laid out
without kinks
Make sure that the hose end is
above the surface of the water
Ensure that the fall is at least 1
cm per metre
Ensure that the hose is laid out
as straight as possible
The bend must be increased to
at least D = 40 mm

9.3
Foil grinding wheels
These wheels can be turned around and remounted after one side has been used up,
thus allowing you to continue working. This increases wheel life considerably.
9.4
Replacement grinding wheels
Replacement wheels are always supplied with a tube of grease for sealing the wheel
chamber.
i
i
We strongly advise against installing a replacement wheel on top of
an already installed wheel, regardless of its origin and type.
Warning!
If diamond wheels are used, you will experience extreme wheel wear
when grinding embedding materials and metals. We assume no
responsibility for this.
When using a replacement wheel, follow the instructions provided for
!
changing wheels.
