AUTOMATIC LOCK
NOTE: If tension is removed well below rated range of the balancer during spring adjustment, lock will engage. It
is necessary to apply more tension to release the lock.
If a spring should break or lose tension for any reason, an automatic lock will engage to prevent drum from
turning. Lock will disengage when tension is applied to a new spring.
CABLE STOP ADJUSTMENT
Adjusting cable stop is not recommended due to reduction in active travel distance, and difficulty. If
additional cable extension is required, extension cable assemblies are offered as an accessory item. In
addition, special cables are available if needed.
SERVICE
TOOL REPLACEMENT
WARNING: Never release drum lock unless full load is hung on balancer. If released with no load,
hook will retract rapidly. Hazards or unsafe practices COULD result in severe personal
injury or death.
Pull tool down to the most convenient height and set manual drum lock
by lifting tab, allowing pin to snap in (see illustration). This locks the
drum in place. Tool can now be removed and replaced. After replacing
tool, the drum lock can be released by pulling outward on tab and
folding it back into its original position.
CABLE REPLACEMENT
CAUTION:
Never release drum lock unless full load is hung on the balancer. [If it is necessary to
disassemble balancer to change cable, always remove all spring tension prior to
disassembly (see Spring Tension Adjustment.] Hazards or unsafe practices MAY result in
minor personal injury or product or property damage.
Whenever cable shows signs of deterioration, it should be replaced
with a new cable. To replace cable, there is no need to
disassemble balancer, remove tension, and/or remove it from its
location. Simply pull cable to its extreme lower limit, exposing
threaded plug in the drum as shown in the illustration. Engage
manual drum lock (as described in “Tool Replacement”) and remove
tool. Remove plug and old cable. Insert new cable and replace
plug securely. Reattach tool to lower hook and disengage drum
lock.
