A3.5 C3.5 D3.5 E3.5 G3.5 NA3.5 OA3.5 A3.5 OG3.5 NG3.5 Technical Data Adjustment: Adjustment of thedamping rate is achievedby pulling (or pushing) thepiston rod to its fully extended (or compressed) position.Whilst still pulling thepiston rod turn it clockwise to increase damping and anti-clockwise todecreasedamping. If the resistance increases noticeably, stop adjusting to avoiddamage. The adjustment can add amax. of 0.24" (6mm) to the Ldim. shown (adjustment instruction seepage116). Positivestop: Providemechanical stops0.04" to0.06" (1 to1.5mm) beforeendof each strokedirection. Free travel: Constructionof standarddamper results in a free travel of approx. 21%of stroke. Material: Body: Black coated steel. Piston rod: Stainless steel AISI 303. End fittings: Zincplated steel. Separator piston: Available as a special option to remove free travel.
