after the motor is switched off.
9. BLADE
The blade is made of pressed steel. It will be necessary to
reshape it frequently (with a grind wheel).
Ensure that it is always balanced (an unbalanced blade
will cause dangerous vibrations). To check for balance,
insert a round rod through the central hole and support
the blade horizontally. (Fig. 20) A balance blade will
remain horizontal. If the blade is not balanced the heavy
end will rotate downwards. Reshape the heavy end until
the blade is currently balanced. (Fig. 21) To remove the
blade (2), unscrew the blade screw (3). (Fig. 22, Fig. 23,
Fig. 24)
Check the conditions of the fan (1), and replace any parts,
which are damaged. (Fig. 22)
When reassembling, make sure that the cutting edges
face in the direction of the motor rotation. The blade screw
(3) must be tightened to torque 20-25 Nm.
WARNING: For service, replace the blade with:
DOLMAR 263001422 (for EM-330) and DOLMAR
263001414 (for EM-370) only.
