4.3A ADJUSTING THE COUNTER-THRUST WHEEL

The wheel must be adjusted so that it does not press on
the support profile, to thus avoid increased friction.
Counter-thrustwheeladjustmentprocedure:
• LoosenthescrewM6(Fig.30ref.1).
•
Adjust the height of the wheel support, making it come
ascloseaspossibletothemainprofilewithouttouchingit
(Fig.30ref.2).
•
Whenyouhaveadjustedthewheel’sheight,tightenthescrew
M6(Fig.30ref.a).
Ifnecessary,useashimofabout0.5mm,placingitbetweenthe
wheelandthemainprofile,removingitwhenyouhavefinished
theadjustment.
Movetheleavesbyhandandcheckifthecounter-thrustwheel
