B) Checking the blade brake

WARNING! Correct operation of the brake,

which must ensure that the blades stop within 5

seconds from disengagement; longer stopping

times do not comply with the safety standards.

If the blades do not stop within 5 seconds from disen-

gagement, appropriate checks must be made to the

electrical system and the clutch must be re plac ed if

no result is achieved.

A) Adjusting blade engagement

Con il piatto di taglio nella posizione più bassa, indi-

With the cutting deck in its lowest position, look for

the adjuster (1) which is placed under the footboard

on the left side and turn the nuts, with the blades en-

gaged, until the spring (2) reaches a variable length

«A» according to the dierent versions of the ma-

chine, as follows

A = 113 ÷ 115 mm - for mod. 102

A = 90 ÷ 91 mm - for mod. 122

NOTE The hook position of the spring (2) on the

plate (3) is dierent for the model 102 (hole 3a) and

the model 122 (3b – the only hole on the plate).

Validity

General informations

The blades are driven by the engine by means of

a “V” belt and are engaged by an electromagnetic

clutch.

After a certain amount of use the belt can become

longer which can result in malfunctioning, i.e.:

– belt slipping = belt stretched

– diculty in disengaging, with the blades con

tinuing to run = belt shortened

In both cases the stretcher needs to be adjusted.

Disengaging the blades causes the cutting in

of a brake, incorporated in the electromagnetic

clutch, whose task is to stop the blades from ro

tating within ve seconds.
