SI-F670A
Front Drive System
Before use, read these instructions carefully, and follow them for
correct use.
CAUTION
• Be sure to use only a Shimano HG chain in
combination with the FC-T300/FC-T301 front
chainwheels.

Model number
Note
• Apply grease to the bottom bracket before installing it.
• For smooth operation, always be sure to use the specified
outer casing and the bottom bracket cable guide.
• This front derailleur is for triple front chainwheel use only. It
cannot be used with the double front chainwheel, as the
shifting points do not match.
Outer casing holders
• When installing the top route type, choose
a frame that has three outer casing holders
as shown in the illustration at right.
• Use an outer casing which still has some
length to spare even when the
handlebars are turned all the way to
both sides. Furthermore, check that the
shifting lever does not touch the bicycle frame when the
handlebars are turned all the way.
• Grease the inner cable and the inside of the outer casing
before use to ensure that they slide properly.
• For any questions regarding methods of installation,
adjustment, maintenance or operation, please contact a
professional bicycle dealer.

5. Troubleshooting chart
After completion of steps 1 - 4, move the shifting lever to check the
shifting. (This also applies if shifting becomes difficult during use.)
If the chain falls to the crank side.
Tighten the top adjustment
screw clockwise (about 1/4 turn).
If shifting is difficult from the
intermediate chainring to the largest
chainring.
Loosen the top adjustment
screw counterclockwise
(about 1/8 turn).
If shifting is difficult from the
intermediate chainring to the smallest
chainring.
Loosen the low adjustment
screw counterclockwise
(about 1/4 turn).
If there is interference between the
chain and the front derailleur inner
plate at the largest chainring.
Tighten the top adjustment
screw clockwise (about 1/8 turn).
If there is interference between the
chain and the front derailleur outer
plate at the largest chainring.
Loosen the top adjustment
screw counterclockwise
(about 1/8 turn).
If the intermediate chainring is skipped
when shifting from the largest
chainring.
Loosen the outer casing
adjustment barrel
counterclockwise (1 or 2 turns).
If there is interference between the
chain and front derailleur inner plate
when the rear sprocket is shifted to
the largest sprocket when the
chainwheel is at the intermediate
chainring position.
Tighten the outer casing
adjustment barrel clockwise
(1 or 2 turns).
If the chain falls to the bottom bracket
side.
Tighten the low adjustment
screw clockwise (about 1/2 turn).
Replacing the indicator
1. Press button (B) to set the lever to the lowest position.
2. Insert the pin of the indicator gear into the hole of the winding reel.
3. Move the indicator needle to the [1] position.
4. In the condition in step 3., place the indicator on top of the brake
lever bracket. Be careful not to let the indicator needle move at this
time.
5. Secure the indicator with the two indicator set screws.

to a larger chainring
When lever (A) is pressed once,
there is a shift of one step from
a small chainring to a larger
chainring.
Example:
from intermediate chainring to
largest chainring.
