Installation Guide

I N S T R U C T I O N S
Congratulations! You have just become the proud
owner of a
Holey Galahad
®
, the successor to the
Galahad
®
tungsten carbide discs. Holey Galahad
®
incorporates new See-Through technology which
enables you to see where you’re going and where
you’ve been - a
Window To Your Work! To maximize
your enjoyment these instructions will answer simple
questions on fitting your
Holey Galahad
®
and give
you cleaning tips.
New, Redesigned Universal Nut:
King Arthur's Tools
®
Universal Nut
(part #13750 for 5/8” center shafts
and part #14000 for 7/8” 22mm
center shafts) now has a recess
in the base that allows any angle
grinder in the world to accept the
Holey Galahad
®
– this specifically
solves mounting the thinner
Holey
Galahad
®
models.
Why We Created An IMPROVED Universal Nut:
Angle grinder manufacturers are not consistent in
the height of the raised round arbor shoulder over
which
Holey Galahad
®
is seated, nor in the width
of their locknuts, which have varying diameters.
This caused problems we had to overcome, which
we did by redesigning our Universal Nut. The flat
Holey Galahad
®
body is slightly thicker than the
round model and, in most cases, when seated
over the arbor, will be level with, or rise slightly
over the arbor. In this case using the angle grinder
manufacturer’s locknut will tighten and secure
Holey Galahad
®
. The round profile Holey Galahad
®
has an inner wall design and slightly thinner metal
thickness that is not compatible with most grinder
locknuts used to tighten the disc. When the disc
is seated, it falls
below the arbor
shoulder, not allowing
standard lock nuts to
secure the disc. This
causes the discs to
spin freely. Always
use the optional
New Universal Nut
to securely attach
discs to the grinder.
Using our
New Universal Nut, you can seat any
style Holey Galahad
®
, but especially the round
profile, over the arbor and tighten using a 21mm
spanner or wrench
over the hexago-
nal head nut. The
depression in the
nut seats over the
arbor and securely
tightens the disc.
The improved
Universal Nut
also seats snugly
into the deep well
center of
Holey
Galahad
®
.
Cleaning The
Discs:
Over time
and use
, a section
of the disc will
eventually fill with
wood, resin or
other material.
Clogging caused
by resinous or fibrous wood can be brushed out or
burned off without damaging the teeth. The tungsten
carbide has been brazed on at 2800º Fahrenheit, so
standard burn-off temperatures aren't going to affect
it at all.
Make sure you wear gloves and use vise grips
or pliers to keep your hand from the heat when
applying a propane torch to the burrs - they
transfer heat very quickly. Always make sure
the angle grinder is disconnected from main
power source.
Burning
Use a small propane burner (e.g camping burner)
and apply to disc. Let sit until cool and use a brass
or bronze wire brush to remove loosened debris
and residue.
1. You will not damage the disc. Common sense
dictates that you remove the disc from the angle
grinder and place it on a non-flammable surface
prior to burning.
2. Another preferred method is to apply paraffin
to the disc first, then burn and brush clean as
described above.
Applying Oven Cleaner
Spray “Easy Off” oven cleaner (or similar product)
to disc. You can apply directly to the disc while fitted
to the disconnected angle grinder but beware, you’ll
probably also spray the safety guard. It can get a
little messy. Better still, remove the disc, lay on
newspaper then spray on oven cleaner. Let sit for
about half an hour and remove residue with a brass
or bronze wire brush. Repeat as necessary.

• Recommended for use with disc/angle grinders
equipped with constant pressure switch (paddle,
dead man or kill switch.)
• Unplug power source from g
rinder when assembling,
cleaning, sharpening or removing the tool. Grinder
switch must be OFF before connecting power.
•
It is EXTREMELY IMPORTANT the safety guard
is RESET to the ‘CORRECT’ position as detailed
in these instructions. DO NOT REMOVE SAFETY
GUARD OR AUXILIARY HANDLE.
• Always ensure work piece is securely held in a vise.
Do not grip or support the work piece with hands,
feet or other body parts.
• Work gloves and footwear are highly recommended.
• At all times, use both hands to operate the grinder.
• Always use safety glasses and/or a full face visor
during operation.
• Inspect and remove all nails, staples and wire
obstructions from lumber before carving.
• Never start the grinder when the disc is in contact
with stock material.
• Never put the grinder down until it has stopped
completely. Failure to do so could cause the grinder to
‘walk’, causing injury or damage. Similarly, do not ram
the disc into wood to stop it tur
ning prematurely once
the po
wer s
witch is tur
ned off.
• Regularly clean the disc grinder’s on/off switch and
remove wood shavings and dust. Accumulated
debris around and under the switch could clog the
mechanism, making it hazardous in operation.
• Only operate Holey Galahad and Galahad discs at
a safe distance from others.
• Let the cutting tools do the work. They are fully
capable. Do not force tools into the work or apply
excessive pressure.
• Keep hands away from Holey Galahad’s face and
edge during operation. Do not reach underneath work
or attempt to remove material while discs are rotating.
• Keep discs clean and sharp by burning the residue
with a small propane burner or using oven cleaner
and wire brush.
• Read these instructions in conjunction with the disc
grinder owner’s manual for additional user instructions
and safety rules.
