Plaster Trimmer MT1
No.1800-0000
Areas of Caution
Observe the regulations for prevention of accidents of the Employer's Liability Insurance Association and
the following safety precautions when trimming:
• Do not touch the disc when trimmer is live because there is danger of injury as soon as the
machine runs.
• Do not work at the trimmer with long, untied hair or loose clothes. By winding them into the
running machine, there is danger of injury.
• The unit is intended for trimming plaster models only.
• Do not open the front cover whilst the motor is running. Although the motor switches off
automatically when the front cover is opened, the disc continues rotating.
• Wear your safety goggles when trimming.
• Open the front cover only after the complete standstill of the grinding disc.
• Never reach into a rotating disc.
• Never work without the model tray. There is a risk of injury if small parts or fingers enter the space
between the disc and the casing.
Cleaning / Maintenance
In order for the trimmer to function correctly, it is important that the water inlet and outlet hoses are kept
clean.Therefore, the trimmer should be cleaned at least once per week.When doing so, turn the mains
switch to 0, unplug the trimmer and turn off the water supply.Once the disc has come to a complete
standstill, undo the red fasteners (5) on the right of the housing pressing them back gently, open the front
cover and lift it off its hinges.Brush the cover under running water, ensuring that the interior surfaces and
the water outlet are also cleaned. After cleaning, replace the cover on its hinges and fasten it on the right
hand side.
Replacing the disc:
Turn the mains switch to 0, unplug the trimmer and remove the front cover, as described in "Cleaning /
Maintenance".Ascertain that the motor has come to a complete standstill.Remove the cap (8) from the
left hand side of the housing, insert the rod (9) into this opening and lock the disc into position so that it
can no longer rotate.Insert the Allen key (10) into the screw in the centre of the disc and loosen it by
truning the key anticlockwise. Change the disc and, before finally tightening the central screw, manually
turn the loosely affixed disc once or twice on the joint. In this way the disc will find its optimum centre.
Now manually turn the screw with the key in a clockwise direction.
Remove the locking rod and reposition the cap over the opening. Replace the front cover on its hinges
and fasten it.Plug in the trimmer.
