Mechanical Adjustments

This section deals with any minor mechanical adjustments you may need to make to the new sledge if necessary such as:-

Adjustment of clamp arm height if needed.

1. Make a selection.
2. With the CD on the turntable, adjust the clamp arm height with the clamp arm adjustment screw see Fig-10.
3. The clamp arm height should be set so that there is no more than 2mm of magnet showing between the CD top face and the magnet clamp head as shown in Fig-11.
   Fig-10, Fig-11
   

Aligning the sledge and gripper arm if needed

1. With the CD on the turntable and playing a track, adjust bracket “A” with a pair of pliers left or right until you have equal distance between the CD and the gripper arm as shown in Fig-12.
   Fig-12
   

Setting the clamp arm height in the rest position

1. With no CD on the player make an adjustment to the hex cone see Fig-15 so that the clamp arm is in one of two positions depending upon the serial number of your machine see Fig-13 and Fig-14.
   Fig-13
   
   In standby the clamp arm should be 30mm above the deck for machines from serial number3209 on-wards.
   Fig-14
   
   In standby the clamp arm should be horizontal with the deck for machines up to and including serial number 3208.
   Fig-15
   

Notes

1. When a CD fails to initialised, the display on the new sledge unit will respond with “BAD TOC or DISC”. The CD will remain on the sledge unit until the S&CC unit issues a reject command to the sledge, this can take approximately 45 second. (TOC = Table Of Contents)
2. Please make sure you have read all the installation instructions as some minor adjustments may be necessary to the sledge metal work as listed in section-20 when installing this kit into your machine.
3. If you encounter any issues please contact your supplier.
