GENERAL INFORMATION
Removal of Cables
Installing New Cables
A.
Turn unit upside down on flat surface.
B.
With a box end or hex socket wrench, loosen the two hex head bolts to relax the strap clamps
holding the power shaft. The power shaft will turn about one revolution when free of the
clamps-keep one hand on the power shaft while loosening the clamps so it will not spin
suddenly and cause to "spill" off from the power drums.
C.
With the aid of another person, unwind the cables from the power drums by pulling the
cables up evenly (allowing the power shaft to turn) until the cables are completely off the
drums. Do not allow the cables to "spill" off the power drums, as this puts an undesirable
twist in the cables.
D.
With a Phillips head screwdriver, remove screw A and screw B from the power drum and put
in a safe place. Do on other side.
E.
With a box end or hex socket wrench, loosen (do not take apart) the carrier pulleys and tape
lock washers on each side.
F.
With needle nose pliers, pull out the ends of the cable, found in the center of the power drum,
about 6" towards you. In back of the two cable ends, find the power drum key. With the
needle nose pliers, work the key up and out. Remove the cable through the hole the key
came out of. Remove the cable from the carrier pulleys and tape lock washers; discard
cable. Re peat on the other side.
A.
Center 11 ft. cable between two bottom lock washers. Thread through lock washers and
through the guides just above. Bring cable towards the center of the unit, threading between
carrier pulley and carrier cable retainer. Tighten hex lock nut on carrier pulley as the retainer
is up against the metal flange as far as it can go. Repeat on the other side.
B.
Position the power shaft with the hole straight up and with the arrow pointing in the direction
of the limit cable.Align the hole on the power drum with the hole on the power shaft, showing
heads of screws towards you.
C.
Place ends of the cable in the hole and pull on the ends with a pair of needle nose pliers,
bringing the ends out about 6". Do not twist the cables; make sure the right cable is on the
right side and the left cable is on the left side.
D.
Take the power drum key and place in the hole in back of the cables. With a 1/4" punch
(screwdriver will do) and a hammer, drive the key down into place making sure it has entered
through both holes.
E.
Pull cables up as far as they will go, and replace screwA in between the right and left cables.
Pull the cables in the direction of the arrow and replace screw B over the cables.
F.
Repeat steps B through E on the other side.
G.
Hold the cables up, to hold them taut. There will be two loops on each side-use your thumb
and index finger to support the loops on each side.
H.
Have another person wind up the power shaft in the direction of the arrow stamped on the
power shaft, until all of the cable is wound back into the power drums.
I.
Once the cable is wound tight, continue to turn the power shaft an additional 3/4 to one turn
(for head load required to support the weight of the mechanism), and tighten the clamp bolt
to prevent the tube from turning.
J.
Align the groove on the tape lock washers with the cable. Tighten down the tape lock washer
to prevent slippage of the cable in future use.
K.
Place the unit back in the counter and depress the platform fully several times to allow the
cables to attain their natural position on the power drums.
L.
If the platform is level, the cable replacement is complete. If the platform is uneven, loosen
the four tape lock washers and allow the cables to shift into a balanced tension. To help
attain the condition, grip both power drums and apply torque in the direction of rotation that
will put additional tension on the cables. Tighten the four tape lockwashers and re-install the
unit in the counter.
