Page 2 HB-110 and HB-240 with aluminum blades. The longer arms are angled so they will nest when installed on every axle. Venco’s policy is to distribute counterbalance weights evenly among the blades to minimize linkage loading and to improve blade closure.
Page 3 Counterbalance Adjustment 1. Adjust FULL OPEN blade stop first. On most models, a bolt with a spacer is used through the top linkage clevis arm. Open and close damper to verify there is no interference between the axles and the nested counterweight arm.
Page 4 If there is a problem, check for loose linkage. Our Commitment As a result of our commitment to continuous improvement, Venco reserves the right to change specifications without notice.
