Important Notes
!
• Turing wheels is done at your risk. Minoura is not liable for any damage that may be caused by improper use of the stand. Wrong wheel adjustment may cause poor brake performance or spoil bike stability. You can use FT-1 only when you accept this caution. And Minoura will understand you accept this caution when you start using FT-1.
• Only use the FT-1 to true bicycle wheels and for no other purpose.
• FT-1 will work with 9mm quick release skewers and xed nut axels, too. 15mm / 20mm thru axle can be used when using optional adapters. Any other size thru axle will not t to FT-1.

• Both pillars are constructed to move together. This helps to readjust the gauge position when changing to a different hub. This is NOT an "Auto-Centering" feature. You must use a wheel dishing tool to check wheel symmetry.
• When mounting a wide hub and tightening the skewer, the wheel may not seat correctly because the axle holders are angled.
Push down the wheel to set it in the deep-
est position on the Axle Holder when you tighten the quick release skewer.
• You will use only one Side Shaking Gauge when checking the wheel. Widely open and lock the gauge arm which you don't use.
When you need to order replacement parts, refer the schemastics on the last page then order it with the correct part number or part name.

Side Shaking Gauge
Side Shaking Gauge is for checking the horizontal movement of the wheel. The purpose of this job is making the distance (gap) between the rim surface and the brake shoe equal on all around the wheel in order to expect greater brake performance. This job can be accomplished with the tire on or off the wheel.
Set the wheel on the stand and position the tip of the Side Shaking Gauge 1 - 2mm away from the rim surface (do not touch). (see Fig. C)
Rotate the wheel slowly (do not spin fast) and look at the clearance between the rim surface and the gauge tip. The gap will change vary and when the rotating wheel comes in contact with the gauge, you will hear a scratching sound.
Widely open the arm until it's caught by the locking ratch
(Fig. D)
The side shaking gauge arm can be locked in widely open position. Hold the arm and move open. When the arm is caught by the locking ratch, you will feel click. This is the locking position. (see Fig. D) Do not force to open more. To close the arm, push it inward.
Turn the nipples to make this gap equal on all around the wheel.
(Fig. C)
(Fig. E)
Turn the Side Gauge Adjust Knob, then both arms move together. If the arm is in locked position, it won't move even you turn the knob.
In case that you see the wheel from right hand side to true the wheel.
On side shaking truing job, you use either right or left side gauge. You will not use both gauges at once. Depends on your dominant eye, use the gauge arm on your favorite side. Fig.C shows then case you are dexitral.

Metal Rim Position
(metal tip is projected)
Carbon Rim Position
(metal tip is retracted)
(Fig. F)
Turing wheels means the gauge has to touch the rim and this may cause some light scratching.
the rotating wheel comes in contact with the gauge, you will hear a scratching sound.
If you use an expensive carbon rim and you don't want to scratch it, flip the metal piece on the Side Shaking Gauge. In this position, only the plastic arm body contacts the rim and it won't damage the rim. (see Fig. F) The contact sound between the tool and rim will become fainter and more difficult to hear.
Turn the nipples to make this gap equal on all around the wheel.
(Fig. H)
(Fig. G)
The angle of the gauge arm should be set as deep as possible. (see Fig. G) If the Vertical Shaking Gauge touch the tire, fold it down or remove the tire.
Vertical Shaking Gauge
Vertical Shaking Gauge is for checking the vertical movement of the wheel. The purpose of this job is making the wheel concentric circle to make the riding smoother. You must remove the tire from the wheel when doing this job.
Raise up the Vertical Shaking Gauge Arm (and extend the arm length by turning the center barrel type knob if necessary) to position the tip 1 - 2mm away from the rim edge (do not touch). (see Fig. H)
The gauge arm angle against the rim should be as deeply as possible.
Turing wheels means the gauge has to touch the rim and this may cause some light scratching.
If you use an expensive carbon rim and you don't want to scratch it, remove the metal bracket from the Vertical Shaking Gauge and only the plastic part contacts the rim. Be sure the contacting sound will have to become very small and difficult to listen.
If the Vertical Shaing Gauge has been
!
twisted by some reason, it will contact only either edge of the rim. Even in this condition, you can continue the wheel truing job without any problem, but if you want to have the gauge contacts both edges at once, twist the gauge.
Rotate the wheel slowly (do not spin fast) and look at the clearance between the rim edge and the gauge tip. The gap will change vary and when
