the USER INSTRUCTIONS).
• Fasten the piston to the rear bracket [17] using the screw M8 x 45mm [19], the bush [20] and the
washer Ø 24mm [21], then tighten the self-locking nut M8 [22] as far as it will go.
• Open the gate wing manually and insert the front coupling pin [25] in the hole of the front fas-
tening bracket [18]. Lock the pin in the bracket using the washer Ø30mm [26] and nut M16 [27]

NB: pay special attention to the correct positioning of the washer on the brackets.
• Insert the protective brushes [12] in the relative guides on the front cover [11] and push them
