SKIRT HEIGHT AND OPERATION CHECK
Drive the machine on a level ground that is suitable for
checking the skirt height.
Turn the main switch (1) to “0”.
Check that the height from the ground of the side skirts
(A and B, Fig. 11) is within 0 and 2 mm.
Check the skirts for integrity, cuts or tears, which can
reduce the machine vacuum capabilities. If necessary
replace the side skirts (see the procedure in the Service
Manual).
Check that the front and rear skirts (C and D, Fig. 11)
slightly rub on the ground. Check the skirts for integrity,
cuts or tears, which can reduce the machine vacuum
capabilities. Note that the front skirt has typical vertical
cuts (E). If necessary replace the front and rear skirts
(see the procedure in the Service Manual).
