9.
Install the cutter pin. Make sure the push rod is fully retracted so that the push wire does not
interfere with the insertion of the cutter pin. The cutter pin has a retaining collar with a flat spot.
Align the flat spot on this retaining collar so that it clears the corresponding flat spot on the cutter
sleeve. The pin can now be inserted in the sleeve. After the pin has been inserted all the way, rotate
it 90 degrees in either direction to lock it in the sleeve.
10.
The cutter pin has two available cutting edges. The cut edge (1 or 2) is selected depending upon the
direction of rotation (clockwise or counterclockwise) after the pin is inserted in the sleeve. The
convention for identifying cut edges is that inserting the pin and turning it 90 degrees clockwise
(when viewed from the top) selects cut edge number 1.
11.
The push wire will be used to help align the magnetizer as it is installed. To extend the push wire out
the front of the Multishot apply slight forward pressure on the push rod while turning the cutter pin
slightly until the holes in the cutter sleeve and cutter pin are aligned. (the holes will be aligned when
the dowel pin, at the top of the cutter pin, is exactly perpendicular to the long axis of the Multishot.)
When the holes in the cutter pin and sleeve align, the push wire will pass through the cutter and
extend out the front of the Multishot.
12.
Thread the push wire through the center hole of the magnetizer and align the two mounting holes in
the magnetizer with the matching holes in the Multishot base. Insert the two main assembly cap
screws from the bottom side and use the 3/32” wrench to tighten the
magnetizer in place. Keep the push wire extended.
13.
Install the needle with nylon ball and the needle clamping nut (figure
3). As in step 11 above, the push wire will be used to guide the needle
into the cutter sleeve. Slide the nylon ball on the needle so it is about
one third of the length down the needle from the tip (the beveled
end). This ensures that the needle will seat against the cutter before
the nylon ball bottoms out in the magnetizer. Use the push rod to
keep the push wire extended out the end of the magnetizer. Insert the
end of the extended push wire into the funnel (or dull end) of the

The cutter pin, which is
installed in step 8, is
the depth stop for the
needle once it has
entered the cutter
sleeve. The cutter pin
must be installed
before the needle can
be properly installed.
