6.
The rear tire should sit in the almost center part of
the Drive Roller without touching any other parts.
(see Fig. L)
If the tire has touched the plastic parts (Fig. M)
due to some reasons like the rear wheel is not trued
correctly or you have installed a too fat tire, you must
adjust the Mag unit position.
To do so, loosen the backside screws with M5 hex
wrench, adjust the roller position, then tighten the
screws again tightly. (see Fig. N)
5.
Contact the Drive Roller to the rear tire by turning the Roller Pressure Adjust Knob clockwise. (see Fig. J)
The best position is that the roller compresses the tire in the depth of 3 - 4 mm. (see Fig. K)

Please note too much and too less roller pressure will bring premature tire wear.
Keep correct roller pressure and maintain the air pressure in correct level before
using M20-D.
!
If it's hard to tighten the knob bolt, lift up the Mag unit by hand then tighten the knob.
