Check the belt screws for
tightness. Check the position of
the wedges.
Check the condition of the belts.
Remove the worn belt by
removing the pulley. Loosen the
two hexagon socket screws and
insert the other screw into the
empty thread. Tighten the screw
to release the lock. Insert a new
belt and slide the pulley back
onto the shaft. Tighten the screws
evenly back to their original
positions.
Check the condition and
attachment of the springs.
Check the condition and bearing
of the belt tensioner pulley and
the tightness of the nut.
Check clutch lever attachment
and movement. Tighten the pivot
nut if there is play in the clutch
lever. Move back and forth. Check
the free position of the switch.
The spring should pull the clutch
fork lever against the larger
pulley. The belt should loosen
from the pulley at the end of the
motor.
Check the attachment of the belt
guard pin (1 piece). Adjust the
distance between the pin and the
belt to 1… 3 mm.
Adjust the spring seat so that the
return side of the belt (the
longest free-space) should move
with light hand force of approx.
10-15 mm inwards.
The protective pin of the motor
pulley should be approx. 5-10 mm
away from the belt when the belt
is taut.
2 hours after the
first start, and after
that 20 hours or one
season.
Check the condition and fastening
of the blades. The blades should
easily rotate around the pin. The
blades have two wearing surfaces.
Sharpen the blades, if they are
worn.
Check the condition of the roller
and the bearings as well as the
fastening.
Check that the front guard folds
up easily and returns with the
springs.
