120 ÷ 122 mm
length of the belt after having been repla-
ced or after a long period of use, the ten-
sion of the spring (1) can be adjusted by
2
turning the nuts (2) until the indicated
measure is obtained (120 ÷ 122 mm mea-

tighten the nuts.
Sharpening blades
Blades that are badly sharpened tear at

the grass, reduce collection and make the
lawn turn yellow. To remove a blade, hold
it firmly wearing strong gloves and undo
the central screw (1) in the direction
indicated by the arrow for each blade,
noting that one of the fixing screw has
1
a right-hand thread and the other one
has a left-hand thread.
Sharpen the two cutting edges using a
medium grade grinding wheel and check
the balance by holding the blade up with a round 18 mm diameter bar inserted in
the central hole.
