DJUSTMENT TO BLADE ENGAGEMENT AND BRAKE

the blade or the time for stopping after dis-
engagement is over 5 seconds, adjust the
spring tension (1).
To make this adjustment, loosen the nuts
(2) and screw or unscrew them on the con-
trol rod (3) in order to obtain a distance of
77-79 mm between the bracket (4) and the
inside of the washer (5), with the blade
engaged and the cutting height adjustment
lever at position "1". When the adjustment has been made, screw the nuts (2)
back on.

DJUSTING THE SPEED CHANGE LEVER
The speed change lever has a clutch device
which keeps it in the position selected during for-

If the lever does not stay in position during work-
ing and has difficulty in returning to neutral, the
adjuster nut (1) will need to be registered to
restore normal functioning.

To remove the blade, hold it firmly wearing strong
gloves and undo the central screw (1).
Sharpen the two cutting edges using a medium
77 - 79 mm
