Drive Wheel Adjustment Screw
The drive wheel adjustment and stop screws allow
a range of adjustment for best performance. After
adjustment, if the trolley still does not meet
specifications, change the motor or motor drive
wheel.
Roller Belt Tension
Roller belt tension must be correct. Too tight, the
belt will generate rolling noise; too loose, the gears
could ruin the belt resulting in trolley positioning
problems.
Visually check belt tension by pressing the belt with
your finger. If tension is correct, the belt should
deflect no more than 1cm.
There is no adjustment available for belt tension.
When the belt is too loose, replace it as follows:
Removing the motor assembly:
1. Mark the position of the old motor to ensure the
new motor is installed in the same location.
2. Remove the two M6 screws at each end of the
motor support.
3. Pull out the motor assembly from the trolley
4. Remove the belt from the motor gear.
Re-installing the motor assembly:
1. Install a new belt and place the motor assembly
in its groove.
2. Re-install the M6 retaining screw to the left in the
picture. Do not secure it yet.
3. Re-install the M6 retaining screw to the right in
the picture. Do not secure it yet.
4. Adjust the position of the motor using the mark
made during the removal process.
5. Securely tighten both screws ensuring the motor
is still in place.
