End fittingsmust bepositively secured to prevent unscrewing. 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 0.31" (8mm) to the Ldim. shown (adjustment instruction seepage116). Positivestop: Providemechanical stops0.20" to0.24" (5 to6mm) beforeendof each strokedirection. Free travel: Constructionof standarddamper results in a free travel of approx. 20%of stroke. Material: Body: Black coated steel or zincplated steel. Piston rod: Hard chromeplated. End fittings: Zincplated steel. Separator piston: Available as a special option to remove free travel.
