1. Part sequences in this manual aregiven left to right, according to the pictures shown
and the assembly sequence i.e. from rear of the followspot to the front.
2. Screws nuts, bolts, washers and rivets are not indicated as they are not sold as spare
parts. In case they are needed for servicing, please add the note “with mounting parts”
to your order and proper parts will be supplied free of charge.
3. Optics have been calculated to the millimeter so each spacer and washer is
extremely important to obtain the optimum optical performance in each model. When
replacing any optical component, please make sure each spacer and each washer is re-
positioned exactly where it was. Failing to do so might result in poor performance after
servicing.
4. LDR declines any responsibility in case a wrong part is ordered. If you are not sure
about the part you need please contact the LDR sales staff first for confirmation
