How To Setup Your MAG-500 Trainer
1
2
3
4
5
Open the frame support legs and fit the rubber feet at the correct angle so the base is in full contact with the floor. Do NOT
remove the round metal plates from inside the rubber feet when fitting.
NOTE: If the both legs don’t touch the floor at same time and if one side of the leg is still being lifted up slightly, pull
up the leg upward strongly then place the trainer on the floor again.
Open both couplings by turning the right side hub handle (see Fig. B) anti-clockwise.
Do not over-loosen the couplings, otherwise the knob or the hub handle may become
unthreaded inside the frame.
Insert the left side of the skewer (quick release lever side) into the left side coupling,
and adjust the rotation of the coupling so the skewer lever sits securely in the large cutout (see Fig. C). This will prevent damage to the skewer during use.
Hold the bike firmly by hand and turn the hub handle clockwise until the coupling
comes into contact with the right side skewer nut.
Apply the Mag unit to the tire by lifting up it temporally to know the wheel position.
If the tire touches either left or right side platic housing of the Mag unit (see Fig. D),
you must adjust the Mag unit position by loosening two bolts beneath the Mag unit.
Do not forget to tighten the bolts firmly after adjusting.
(Fig. B)
(Fig. C)

Turn the micro adjust knob clockwise to bring the drive roller into contact with the rear
tire. If the tire is compressed about 3mm by the roller, stop turning the knob.
WARNING: Too much or too little contact between the tire and the roller
!
can cause premature tire wear and possibly damage the drive roller.
(Fig. D)
Using The Mag Unit
The Magturbo unit has 7 different levels of load force, replicating actual riding resistance.
The load settings range from high (H) to low (L) and can be adjusted via the white lever on the Magturbo unit or the lever on the thumb
shifter device. The rider may also adjust the load force by shifting up or down among his gears, depending on the level desired.
We recommend that you start with a medium to low load force and gradually work up, increasing force as muscled warm up.
Increasing Load ForceIncreasing Load Force
Increasing Load Force
Increasing Load ForceIncreasing Load Force
To increase the load force, move the white lever on the Mag unit toward the “H” symbol.
(see Fig. E)
If your Mag unit is a remote control type, turn the lever on your thumb shifter device
toward the “H” symbol.
(see Fig. G)

Be sure the lowest selection is not zero load, there still be a small level of force.
If your Mag unit is a remote control type, turn the lever on your thumb shifter device
toward the “L” symbol.

HOW TO INSTALL THE REMOTE LEVER
You can install the remote lever on anywhere the diameter is between 22.2mm (7/8”) and 31.8mm (1-1/4”) like as on the handlebar.
1
2
Fully loosen the knob bolt on the plastic holder until it stops then push down the bolt to open the holder. (see Fig. H)
Place the holder onto the handlebar, shut the holder, and pull up the bolt then tighten it. (see Fig. I)
Shim
(Fig. H)
Depends on the diameter of your handlebar, you must adjust the shim as follows;
!
• 22.2mm (7/8”) - 25.4mm (1”):Install both shims.
• 28.6mm (1-1/8”): Install either right or left side shim.
• 31.8mm (1-1/4”): Remove both shims.
When you install the shim on the plastic holder, make sure the direction of the shim as shown in Fig. J.
(Fig. I)

Trouble Shooting Your Remote Shifter Unit
If you cannot shift to either the lowest “L” or the highest “H” position, it is possible that the inner wire of the remote shifter cable is too
long and the wire tension is loose. If so, please adjust the tension with the following steps;
Nut Plastic Cap
1

3
Set the remote shifter lever at “H” position. Remove the remote shifter device
from the handlebar and straighten the cable.
Remove the plastic cap located on the bottom of the cable. (see Fig. K)
Hold the adjusting screw with your right hand and push it towards the direction of
the outer cable, then adjust the nut with your left hand to make the wire tension
properly.
