2. Using the appropriate equipment, check the balance
of the blade (1) to make sure that there is a maximum
difference of 2 grams between one side and the other.
Abnormal vibrations that are not caused by the condition or the balancing of the blades,
can cause shaft deformation or excessive play of the support bearings.
• Move the cutting deck to the “Maintenance/Washing” position and remove the blades.
.
1. Apply a comparator with magnetic support (1)
on a flat part of the inside of the cutting deck.
2. Place the probe (2) on the protruding cylindri-
cal part of the shaft (3) and reset the instru-
ment.
3. Rotate the shaft manually. The displacement
(and therefore the radial clearance) on the
complete turn must not exceed 0.1 mm.
With a higher radial clearance, the entire support / shaft assembly must be replaced
.
