MOTOR POSITIONING
Do not roll and retract the projector lift continuously
over 4 minutes at a time to avoid overheating. If the motor
overheats, wait 30 minutes for cooling. No lubrication is
needed for the motor, the drop and retract limit of the
projector lift has been prepositioned to an optimal
configuration before delivery. In order to avoid motor
damage, please consult your local dealer or a professional
technician when a new position setting is needed.
Use the M4 allen-key for adjusting the upper and lower
limitations of the projector lift, but the distance cannot be
more than value D in the specification table.
