7-12-2.5 Adjustment of the mounting position of the air cylinder

(1) Attach the thread trimmer air cylinder (No.1) by fixing with the bolt (No.2). When the thread trimmer
air cylinder (No.1) is released, there will be a clearance of approx. 1mm at section A. To adjust this
clearance, loosen the set screw (No.4) for the mounting plate (No.3), and move the entire mounting
plate (No.3).
After adjusting, securely tighten the set screw (No.4) for the mounting plate (No.3).
(2) When the thread trimmer air cylinder (No.1) is activated, there will be a clearance of 0.5mm between
the cam follower crank 1 (No.5) and cam follower crank 2 (No.6). This is the standard state. This
clearance can be adjusted by loosening nut (No.7) for the air cylinder (No.1), and rotating the shaft
section (No.8) of the air cylinder (No.1).
After adjusting, securely tighten the nut (No.7) for the air cylinder (No.1).
