grinding bit. End of hose should be about 1/4" from surface of bit, and water stream should be directed
so that it wets the bit near the platform surface. This hose placement will ensure best bit cooling and
longest bit life.
7. Alternate hose location: If preferred, the water hose may be kept above the platform surface. In this
case, push the hose through the hole in the rear of the Wing Bracket. A sponge may be placed between
the end of the hose and the bit, if desired. If a sponge is used, be sure to clean and/or replace the sponge
frequently. Keep the sponge wet and be sure the sponge touches the grinding bit. New sponges may be
cut from common kitchen sponges.
8. Place the supplied lter material in area provided in front of pump inlet in the Upper Base of the
grinder. This lter material should be ushed with fresh water regularly to keep it clean. Replacement
lter material can be obtained at aquarium supply stores. If the pump should become clogged, it can be
cleared by blowing into the hose from the grinding bit end.
9. Fill reservoir in Upper Base of grinder with water. Water level should be as high as possible without
overowing. Add grinder coolant if you prefer.
Hose Placement for use with Second Story
1. The Second Story is useful when a second grinding bit is attached to the motor shaft above the primary
grinding bit. The upper grinding bit is usually smaller in diameter than the primary grinder bit and may
be left in place even when the Second Story is not used. If the upper grinding bit is used, then water
must be supplied to the bit for cooling.
2. To use the upper bit, remove the Wing Bracket from the main platform, then place the Second Story
in position by snapping it onto the grinder platform, making sure that the hole in the Second Story is
aligned with the grinding head.
3. Snap the Wing Bracket into position on the Second Story.
4. Route the water hose through the hole in the back of the Wing Bracket. Point the hose towards the
grinding bit. A sponge may be used, but cooling of the bit will be better without the sponge.
Changing Grinding Heads
1. The Gryphon Twister is supplied with 3/4" and 1" Gryphon Slip-On Grinding Bits. To change bits,
simply pull the installed bit straight up. If the new bit is the same size, drop it over the white plastic
shaft adaptor. If the new bit is a different size, use the appropriate adaptor. Rotate the bit until it drops
into place (top of the bit will be level with top of the adaptor). The smaller white plastic adaptor is held
in place with a setscrew, and may be adjusted up or down as desired. Also, most brands of standard
grinding bits will t this grinder.
2. It is recommended to place a little lubricant, such as petroleum jelly, on the shaft to aid in future grinding
bit changes.
