How To Use FCG-310

To open the FCG-310, loosen the Knob Bolt then open the Frame with both hands.
Look for the grooves on the inside of the Ratches that x the angle when the Frame is opened.
Extend until the grooves meet and lock into place by pushing them each other.
Turn the Gauge Plate counter-clockwise to locate the hole at the down end side.
Put the Gauge Plate on the at groove on the outside of the Ratch.
Tighten the Knob Bolt, but you don't need to tighten it so rmly at this moment.
If the Gauge Plate doesn't t to the at
groove on the Ratch correctly, you won't
be able to measure properly. And also
the Gauge Plate will have to be bent.
Please be sure that the Gauge Plate
cannot be replaced.
5.
Attach the FCG-310 to the wheel as shown in Fig. A.
While keeping both Rim Guides touching the rim, loosen the Knob Bolt to adjust the Gauge
Plate position, then tighten the Knob Bolt when the Gauge Plate end touches the hub.
At this moment, make sure the following points;
• Both Rim Guides touch the rim.
• The wheel axle is running through the hole on the Gauge Plate, and the Gauge Plate
touches the hub.

Flip over the wheel and attach the FCG-310 onto
the opposite side of the wheel. Do not change the
Gauge Plate position yet.
At this time, if all three points (both Rim Guides
and the tip of the Gauge Plate) touch each
appropriate position at once on both side of
the wheel (see Fig. B), your wheel is properly
assembled and adjusted.
But if either one of the Rim Guides or the Gauge
Plate doesn't touch the appropriate position (see
Fig. C), your wheel needs to be adjusted further.
Properly Adjusted
(Fig. B)
Wrong Adjsuted
If the Rim Guide doesn't touch the rim, the wheel has been moved toward opposite side.
If the Gauge Plate doesn't touch the hub even though both Rim Guides touch the rim, your wheel has been
moved backward.
Set the wheel on the wheel truing stand to adjust. To know how to adjust the wheel, refer the instructions
manual of the truing stand.
It is crucial to measure the wheel at several different points to get proper result.

Useful Additional Features
FCG-310 can be used on most wheels sized between 24" and 27"/700c in the standard position.
In addition, you can use it for the smaller wheel (18" or larger) and the wide hub wheel which is used on some DH,
FR and city commuting bikes by changing the the Rim Guide position. (see Fig. D & E)
<To Measure Smaller Wheel>
Make both Rim Guides inward
<To Measure Wide Hub>
Step down both Rim Guides

The hole must be outward

How To Fold Down FCG-310
To fold down the FCG-310, 1) loosen the Knob Bolt fully,
separate the Ratches as if pulling outward on each other, 3) rotate
2)
the Gauge Plate as the hole faces outward, then 4) fold the Frame.
Do not tighten the Knob Bolt while the hole of the Gauge
Plate is facing inward, otherwise the Gauge Plate will be
bent. Please be sure the Gauge Plate cannot be replaced.
How To Use NW-300
Insert the wrench of the NW-300 to the nipple fully to the bottom. Do not use any incorrect (wider) size wrench.
Tighten the nipple slowly. You must stop tightening after turning 1/2 rotation at once at widest. These are for
protecting the nipple from damage. Once the nipple is damaged, you won't be able to continue any work on wheel.
Do not continue using the NW-300 if it doesn't t
your nipples. Use another nipple wrench.
