Counterweight
Screw the counterweight onto the stud ,turning with the knurled portion only (see warning). The female threaded part of the counterweight is designed to provide a friction fit onto the stud. If for any reason this is not the case, use a small nosed pair of pliers and gently squeeze the two halves of the threaded end together, reinstall and check. It is sufficient if a very gentle pressure with the fingers fails to rotate the counterweight.

Fitting Cartridge
There are three sets of cartridge fixing screws provided. Use the longest that is practical. Make certain however that they tighten firmly onto the cartridge before they reach the bottom of their holes. This can be done by running one fully home and comparing the mounting lug of the cartridge with the exposed thread. To make later adjustment easier, align the cartridge with the mounting block. This can usually be done by pushing the cartridge against the screws before tightening. The electrical connections will adjust to fit most sizes of cartridge pins. If they have to be reduced in size, it is useful to put a pin of slightly smaller size into the terminal and squeeze down lightly with a pair of pliers. Likewise, careful use of a screwdriver or knife blade will open them up. They should be installed with either very fine nose pliers or tweezers. When removing connections, it is advisable to prise them off with a screwdriver rather than use pliers, as this puts less strain onto the wire.

Install Arm tube
Slide the arm tube into its hole in the pivot casting. Install and lightly tighten the clamp. If a tight fit in the hole, a thumb in the slot will ease movement temporarily. Referring to the main drawing, install the connecting plug creating a loop with the wires. The rear of the arm tube should slightly protrude from the casting preparatory to final adjustment and the cartridge should be vertical. The wires should dressed so as not to touch any part of the arm whilst in operation.
