MINOURA VFS150 Instruction Manual page 6

Contact the Drive Roller to the rear tire with the following steps;
5.
1) Pull up the Foot Pedal to release the VFS unit lock.
2) Turn the Micro Adjust Knob clockwise until the roller
comes close to the rear tire 2 - 3 mm. (see Fig. I & J)
Do not make the roller touch the tire. It will
!
bring too much compression to the tire
and will ocuur premature tire wear or burst
problem.
TIPS
If it's hard to tighten the knob bolt behind
the Foot Pedal, lift up the VFS unit by
hand then tighten the knob.
! If you cannot rotate the knob but the drive
roller is still far away from the tire, the knob
has been locked by the termination of the
hex head of the inside bolt.
Loosen the knob slightly and pull the knob
for inserting the hex bolt head into the hex
hole on the knob. (see Fig. J)
While pulling the knob, tighten it until the
hex bolt head sinks into the hole.
3) Push down the Foot Pedal to contact the roller to the tire.
(see Fig. K)
Check if the roller compresses the tire in proper depth.
4) To release the roller from the tire, just pull up the Foot
Pedal.
The best position is that the roller comp-
!
resses the tire in the depth of 3 - 4 mm.
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 VFS150.
TIPS
Foot Pedal can repeat the same compression stroke by just pushing down the pedal.
