• Cable too taut;
• Guide rods dirty.
6.3.1.
C
ABLE TOO TAUT
If the cable is too taut it may be difficult to select the desired weight load using the selector pin
because the cable tension keeps the cross slightly lifted, causing its holes to become misaligned
with those of the plates.
To correct this problem, carry out the adjust the cable tension as described in paragraph 8.1. "Cable
tension"
6.3.2.
G
UIDE RODS DIRTY
If the weight stack guide rods are dirty, it may be difficult to select the desired work load using the
selector pin. In this case the cross remains lifted due to friction produced by the dirt, which prevents
it from going all the way down, especially with low weight loads, thereby misaligning its holes with
those of the plates.
To correct this problem, carry out the maintenance procedure 10.2.2. "Checking the cross, guide
rods, doubling mechanism forks and weight stack plates".
