Cable Guards
Check the cable guards to ensure that they are not
rubbing against the cables and that they are holding
the cables in the grooves of the pulleys. If a cable
guard is not correctly aligned, loosen the bolt slightly,
readjust the cable guard as necessary, and retighten
the bolt.
MONTHLY MAINTENANCE
Grips
Check the grips and replace them if needed.
GUIDE ROD LUBRICATION
Clean and lubricate the full length of each guide rod
by wiping it with a soft cloth containing a lightweight
motor oil, 10W-40 or 10W-30 weight. Apply only a
light coating over the entire length of the guide rod.
Do not use TEFLON
®
or silicone-based lubricants.
CABLE ADJUSTMENT
For the strength equipment to function correctly, the
cables must be tensioned correctly. To check the ten-
sion of the cables, insert the weight pin into the top
weight plate. Next, slowly raise and lower the top
weight by performing one repetition. The top weight
should come to rest just on top of the second weight
when the repetition is completed.
If there is too much tension on the cables, the top
weight will not rest on the second weight, and it may
be difficult to insert the weight pin into the weight
plates. If there is not enough tension on the cables,
the top weight will not be lifted immediately when the
repetition is begun. Ideally, the cable should not move
more than 1/2 in. (1.5 cm) from the resting position
before the top weight is lifted.
If there is too much tension or not enough tension on
a cable, adjust the cable as described in the following
steps.
Tower Pulley Adjustment
Tools required: 5/16" hex key, 9/16" open end wrench
1. Lift the top weight off the
weight stack and insert the
weight pin into the second
weight and the sixth hole
from the top of the weight
rod.
2. Loosen the locknut attach-
ing the pulley to the bracket
in the top of the tower.
3. Move the pulley to the appropriate location in the
bracket. If more slack is needed in the cable,
move the pulley down. If less slack is needed in
the cable, move the pulley up.
4. Make sure that the cable guard is properly orient-
ed (see CABLE GUARDS at the left) and retight-
en the locknut attaching the pulley to the bracket.
5. Lift the top weight and remove the weight pin.
Lower the top weight onto the second weight.
6. Readjust as necessary.
7. Slowly perform a repetition using a light load and
have someone make sure that the cable is not
derailed from a pulley or rubbing on a cable
guard.
