DC535Y/DCZ535Y, DC655Y/DCZ655Y BOOM GATE USER'S MANUAL
Balancing spring (see Fig.8)
Correct balancing is essential if boom gate is going to work properly. Rectify balancing spring only
when the bar is in open position (i.e. the balancing spring is loose).
Four holes (ø15) on the driven lever. The boom gate is normally delivered in the first hole
( DC655Y/DCZ655Y: suitable for bar length from 5m~6m) or the second hole ( DC535Y/DCZ535Y :
suitable for bar length from 4.5m~5m). If you need to change it to the third (3.5m~4.5m) or the fourth
(3m~3.5m) hole proceed as follows:
⚫
When the balancing spring is loose (the bar is in open position), undo the nuts, release the
balancing spring by turning the spring adjusting rod clockwise.
⚫
Connect the spring adapter to the third or the fourth hole of driven lever, tighten with pin and R pin.
⚫
Connect the spring adjusting rod to the balancing spring and spring adapter by turning spring
adjusting rod anti-clockwise. Tighten the spring adjusting rod to make the balancing spring for
ideal condition of use.
⚫
Fasten the two nuts.
