2

Check the throttle shaft movement for smoothness

3

Examine air cylinder (1), joint part and flap shaft for wear

4

Check the secure lever attachment to the throttle grooved end

5

Adjust the pneumatic cylinder assembly pretensioning (C)

 This measurement will be correctly adjusted when the pneumatic cylinder rod is pulled according to corresponding measure.

 Pretensioning eliminates the vibration caused by the valve (throttle), thus avoiding premature wear on the engine-brake assembly.
