7.2 Adjusting bottom derailleur (Cougar S24, S8 Coyote S24, S7)
With handcycles that have more than one cog on the drive wheel, the bottom derailleur moves the chain
to change gears. Once a month, or after any adjustment, check the bottom derailleur. Change gears to all
the gear combinations to make sure the chain does not come off.
To adjust the small cog position
1. Move the chain to the smallest rear cog and the largest top chainring.
2. Loosen the cable clamp bolt (Figure 2.3) until the cable is free.
3. Look down from the top of the handcycle to see that the smallest bottom cog, the chain, and both
derailleur pulleys are in alignment.
4. If they are not in alignment, turn the high gear limit screw (figure 2.1 identified with an H) until
they are in alignment.
5. Wile you pull on the cable, move the shifter to the small cog position (on the drive wheel).
6. On the shifter, turn the barrel adjuster fully clockwise. On the bottom derailleur, turn the barrel
adjuster fully clockwise (figure 2.2), and then turn it one turn anticlockwise.
7. Put the cable into the clamp bolt groove on the bottom derailleur, pull the derailleur cable tight,
and then tighten the clamp bolt.
To adjust the large cog position
1. Turn the low gear limit screw on the bottom derailleur (figure 2.1 identified with an L) anti
clockwise until the derailleur can move freely.
2. Carefully move the chain to the smallest top chainring and the largest bottom cog. Do not move
the bottom derailleur too far. The chain can be caught between the large cog and the spokes.
3. Move the bottom derailleur pulleys in alignment with the largest cog.
4. Turn the low gear limit screw (figure 2.1 identified with an L) until it does not turn easily. If you
have turned the screw too far, the derailleur will move to the outside of the handcycle.
To align the index system
1. Move the chain to the largest top chainring and the smallest bottom cog.
2. Move the shifter for one click.
3. Make sure the chain moves smoothly to the second smallest gear. If the chain makes too much
noise or does not change gears, slightly turn the barrel adjuster. Change the gear again and make
sure the change is smooth. If the chain moves to the third smallest gear, turn the barrel adjuster
clockwise until the derailleur pulleys align with the second smallest gear.
