18. Open the parts bag labeled "ARM ASSEMBLY."
Press a Plastic Bushing (100) onto each welded tube
on the Press Frame (8).
Lubricate the 3/8" x 9" Bolt (52). Attach the Press
Frame (8) to the welded tubes on the Press Base (6)
with the Bolt and a 3/8" Nylon Locknut (50). Do not
overtighten the Nylon Locknut; the Press Frame
must pivot easily.

Press Arm (77). Press a 1" Inner Cap (76) into the
indicated hole in the Press Arm.
Attach the Press Arm (77) to the bracket on the Press

5/16" Nylon Locknuts (64).
Repeat this step to assemble the other Press Arm

the Right Butterfly Arm (11). Wet the lower end of the
Arm with soapy water and slide a Butterfly Foam Pad
(29) onto it.
Lubricate the indicated axle on the Butterfly Top
Frame (33). Orient the Right Butterfly Arm (11) as
shown and slide it onto the axle. Secure the Butterfly
Arm with two Retainer Rings (31) and a 1" Round
Outer Cap (38). Note: Place the Retainer Rings on
top of the inverted Outer Cap and gently tap the
Cap onto the axle with a hammer. Make sure the
teeth on the Retainer Rings bend towards the Cap
as shown in the inset drawing.
