Renfert MT2 Manual

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. The motor switches off automatically when
the front cover is opened, however, the disc continues rotating for approx. 5 sec.
• 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
A clean flow of water and a clear drainage channel are important factors for the smooth functioning of
the trimmer. For this reason the unit should be cleaned at least weekly. To do this switch off the unit,
unplug (11) and close off the shut-off valve. Wait for the disc to come to a halt before opening the lock
(9), then swing the front cover (2) all the way to the left or unhinge. Clean the front cover under running
water with a brush. Use the brush to clean the inner parts and the drainage channel. After cleaning, re-
hinge the front cover and close it using the lock on the right side. Ensure that the spacer ring is present
on the hinge-bolt.
6.1 Changing the trimmer disc:
Switch off the unit, unplug (11), close the shut-off
valve and open the front cover. Change the spray pipe
as per part 6.3.
Using the Allen key SW4 (4) loosen the central screw
in the middle of the trimmer disc by turning it anti-
clockwise. Remove the screw. Clean the support
flange if necessary.
When fitting the new trimmer disc always make sure
that the locking pins fit comfortably in the stabiliser
holes of the trimmer disc. Tighten the screw (5) with
the Allen key by turning it clockwise.
After tightening the screw check the rotation of the
disc by turning it manually. If the disc touches then it
should be removed, turned by 180
replaced. Close the front cover making sure that the
spacer ring is present on the hinge-bolt. Plug in and
re-open the shut-off valve.
