4.7.1 The filter tube
1. Insert 5 to 10 cm of the filter tube through the quick-release clamp.
Hint
You can remove the end of the rigid connector pipe while you mount the filter tube.
Use grease or soap to lubricate the sealing ring to make reinsertion easier.
2. Mount the filter tube into the outlet hose or
pipe approx. 5 cm from the end of the pipe.
3. Place the filter tube in a U-shape in the filter
unit.
4. Make sure that there are no folds in the
tube.
Note
The first time you use the cooling system after changing the filter tube, make sure that
the filter tube expands to its full length when it fills with water.
CAUTION
If the filter tube is twisted or has folds, stop the machine and reposition the filter tube.
Never use the filter tube when you perform dry-cutting.
Never reuse a filter tube.
4.8 Noise
For information on the sound pressure level value, see this section: Noise and vibration levels ►30
To lower the noise, try to decrease the force with which the cut-off wheel is pressed against the
workpiece. The processing time may increase.
