Adjusting drive engagement
If it seems that the forward drive is not
working properly due to a change in
length of the belt after having been
replaced or after a long period of use, the
tension of the spring (1) can be adjusted
by turning the nuts (2) until the indicated
measure is obtained (120 ÷ 122 mm mea-
sured from the outer end of the spring).
Once the adjustment has been made,
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 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.
ATTENTION!
!
Damaged or bent blades must always be replaced; never
