CAUTION:
After making any cable adjustment, pull
the handle using a light load and have someone make
sure that the cable is not derailed from a pulley or rub-
bing on a guard (see CABLE GUARDS on page 10).
INITIAL ADJUSTMENT
Top Weight Pulley Adjustment
—All machines.
Tools required: 9/16" open or box-end wrench, 5/16"
Allen wrench
Note:
This is the primary adjustment for all
machines. If this adjustment does not remove the
excess slack, see ADDITIONAL ADJUSTMENTS on
this page.
1. Remove the access cover by pulling it free at the
bottom and then sliding it up until the two sets of
tabs release.
2. Using a 5/16" Allen wrench and a 9/16" open or
box-end wrench, loosen the nut holding the pulley
in the bracket on the top weight.
3. To increase the tension, slide the pulley down in
the slot. To decrease the tension, slide the pulley
up.
4. Tighten the nut and check the tension as
described in CABLE TENSION CHECK on page
8. If necessary, readjust the pulley.
5. Replace the access cover.
ADDITIONAL ADJUSTMENTS
Handle End Adjustment
—All machines with a
strap and handle
Tools required: 1/8" Allen wrench, cable cutters, util-
ity knife, torque wrench
Note:
Make this adjustment only if the pulley in the
top weight has been fully adjusted to the bottom of
the slot and the cable requires more tension.
Note:
This adjustment is only for increasing the
cable tension because it requires shortening the
cable. Only one end of the cable should be short-
ened.
1. Create slack in the cable by removing the weight
pin and pulling the handle out 15–20 cm (6–8 in.).
Insert the weight pin into the third weight plate
and the tube on the bottom of the top weight.
2. Push the black rubber cover off the aluminum
coupler and slide the cover up the cable to con-
tact the wide pulley.
3. Loosen the four oval-point, 1/4-20-unc set screws
in the coupler and pull the cable free.
4. Cut off 2.5 cm (1 in.) of the cable end using cable
cutters.
Note: Using any other tool may flatten
or disrupt the end strands so that it may be
difficult to reinsert the cable into the hole of
the coupler.
5. Cut off 2.5 cm (1 in.) of the black cable sheath
from the end of the cable.
6. Reinsert the cable and the sheath into the cou-
pler so that all of the bare cable is in the hole.
7. Retighten the four set screws into the threaded
holes. Tighten the set screws equally until they
contact the cable. Then, tighten each screw alter-
nately 1/4 turn, until all are set to 85 inch-pounds
(9.6 Newton-meters).
8. Slide the rubber cover over the coupler, remove
the weight pin, and lower the handle.
9. Check for proper tension on the cable as
described in CABLE TENSION CHECK on page 8.
