Thoroughly clean the shaft and bearing of this lever.
It is imperative that the trip mechanism is free to move, the parts are indicated by the arrow, remove them, thoroughly clean them and refit, do not use any oil. You can refit the arm and move it making sure there is no resistance as it moves the trip lever, you should treat this as the same way you would a trip pawl in a Garrard or BSR deck.
Thoroughly clean the cam gear and make sure all grooves are free from grease. There is a tiny bit of grease on the underside of this gear, clean it off and apply fresh grease.
Refit the lever with the gear making sure it is free to move in the sub chassis, refit the nut underneath. This is often a reason why the changer either doesn't start of continues to change after the record drops. It moves the large idler either to the motor pulley or away after its finished changing.
Refit the cam gear, you will have to rotate it a bit, make sure it goes all the way down, refit the washer and the circlip. Do not leave out the washer, if you do the gear will be too high and the arm will not go high enough to touch the side of the record.
Move the lever for the arm back onto the cam
You have now serviced the sub chassis.
Refit the sub chassis to the main deck, refit the arm and tighten the two screws.
Refit the large pulley and tighten the screws.
Connect the deck to the mains.
Operate the lever to the side of the speed selector knob and check the motor is running.
Turn the RH control to reject, if all is working well, the arm should rise, go to the centre and return to its rest.
The next check is to ensure the arm rises high enough to touch the record, this is done visually, just make sure that the middle of the cartridge end arm is at the the step on the spindle.
When you are happy that all is well, refit the turntable and secure with the circlip, also reclip the motor wiring to the sub chassis.
Refit the turntable and enjoy playing your records.
