Areas of Caution<br />
Observe the regulations for prevention of accidents of the Employer's Liability Insurance Association and<br />
the following safety precautions when trimming:<br />
• Do not touch the disc when trimmer is live because there is danger of injury as soon as the<br />
machine runs.<br />
• Do not work at the trimmer with long, untied hair or loose clothes. By winding them into the<br />
running machine, there is danger of injury.<br />
• The unit is intended for trimming plaster models only.<br />
• Do not open the front cover whilst the motor is running. Although the motor switches off<br />
automatically when the front cover is opened, the disc continues rotating.<br />
• Wear your safety goggles when trimming.<br />
• Open the front cover only after the complete standstill of the grinding disc.<br />
• Never reach into a rotating disc.<br />
• Never work without the model tray. There is a risk of injury if small parts or fingers enter the space<br />
between the disc and the casing.<br />
Cleaning / Maintenance<br />
In order for the trimmer to function correctly, it is important that the water inlet and outlet hoses are kept<br />
clean. Therefore, the trimmer should be cleaned at least once per week. When doing so, turn the mains<br />
switch to 0, unplug the trimmer and turn off the water supply. Once the disc has come to a complete<br />
standstill, undo the red fasteners (5) on the right of the housing pressing them back gently, open the front<br />
cover and lift it off its hinges. Brush the cover under running water, ensuring that the interior surfaces and<br />
the water outlet are also cleaned. After cleaning, replace the cover on its hinges and fasten it on the right<br />
hand side.<br />
Replacing the disc:<br />
Turn the mains switch to 0, unplug the trimmer and remove the front cover, as described in "Cleaning /<br />
Maintenance". Ascertain that the motor has come to a complete standstill. Remove the cap (8) from the<br />
left hand side of the housing, insert the rod (9) into this opening and lock the disc into position so that it<br />
can no longer rotate. Insert the Allen key (10) into the screw in the centre of the disc and loosen it by<br />
truning the key anticlockwise. Change the disc and, before finally tightening the central screw, manually<br />
turn the loosely affixed disc once or twice on the joint. In this way the disc will find its optimum centre.<br />
<strong>No</strong>w manually turn the screw with the key in a clockwise direction.<br />
Remove the locking rod and reposition the cap over the opening. Replace the front cover on its hinges<br />
and fasten it. Plug in the trimmer.<br />

Replacing and cleaning the grinding platform:<br />

The grinding platform is easily cleaned. It can be<br />
removed from the front plate and be rinsed under<br />
cold, running water. After snapping it back into<br />
place, take care that it fits perfecly<br />
(see diagram 1).<br />
98º and 90º grinding platforms are available and<br />
may be interchanged as needed. Both types of<br />
grinding platform are supplied with the trimmer. To<br />
ensure an easier montage of the tables cover them in advance with some silicon oil or detergent water on<br />
