Assembly instructions (continued)
Please Note:
Test for centering by sliding one of the prong stop
guides over the bur and into the hole in the L-bracket.
If the guide slides easily through the hole in the
L-bracket, the alignment is correct. The bur does not
need to be perfectly centered, but it should not rub on
the guide. The hole in the L-bracket is slightly larger
than the threaded portion of the guide to adjust for
minor variations in centering.
Installing Accessory Guides
Step 1:
Loosen the shaft locking screw and slide the shaft and
L-bracket assembly out from the bur. Slip the rear guide lock
nut over the bur (Figure 6). Slide the shaft and L-bracket back
into the body and tighten the shaft locking screw. It’s important
to tighten the shaft locking screw before aligning the guide
since the shaft will lift slightly when the screw is tightened.
Step 2:
To install a channel-setting guide or other accessory, slip the
guide over the end of the bur and into the hole in the L-bracket.
Tighten the rear guide lock nut to secure the guide, making sure
the guide is centered around the bur.
Step 3:
Loosen the shaft locking screw which allows the shaft to
slide freely. Adjust the guide using the shaft adjusting nut so
the bur protrudes from the guide (Figure 7). To change the
distance between the guide and the cutting edge of the bur,
adjust the guide using the shaft adjusting nut. Tighten
the shaft locking screw.
Please Note:
The smaller of the two basic channel-setting guides (see
page 12) is designed for use with small burs that have
tapered shafts below the bur head. Because the tip area
of the small channel guide is less than the 3/32
″ (2.35mm)
bur shank, the guide will not allow burs to slip or go deeper
into the channel. Burs cannot be removed or inserted from
the front of the small guide.
The large channel guide is designed to accommodate larger
burs, such as ball burs, and is especially useful in setting
stones with thicker girdles.
To Install Other Accessories
To install a table guide, the easy-cut prong guide or a pavé
guide, follow steps 2 and 3 (Figure 8).
