Installation (continued)

This shoulder is necessary to mount these heads securely and in the proper position. The diameter of many mounting shoulders is 1” (25.4mm) and both heads require this size. For mounting shoulder diam- eters that are .79” (20mm), a special shim is included in the package contents to provide the necessary spacing.

A variety of adapters are provided to accommodate mounting to Tanaka as well as other units (see sizes listed below). To mount the “Fixed Line” head, (Ref. 1), place the recessed side on to the mounting shoulder of the gear case. When using the 8mm nut, always use the 10mm washer.

The “Manual Feed” head

is mounted in the same Ref. 2A manner, except that the

“Cutter Holder” (Ref. 2-4 show below) must always be used as shown in Ref.

2A & 2B.
