Work Piece and Work Area Set Up
1. Designate a work area that is clean
and well-lit. The work area must not
allow access by children or pets to
prevent distraction and injury.
2. Route the power cord along a safe
route to reach the work area without
creating a tripping hazard or exposing
the power cord to possible damage.
3. There must not be objects, such as
utility lines, nearby that will present a
hazard while working.
General Operating Instructions
TO PREVENT
SERIOUS INJURY:
DO NOT OPERATE WITH ANY
GUARD DISABLED,
DAMAGED, OR REMOVED.
1. Sharpening Scissors -
If possible take the scissors apart
to make the sharpening operation
easier and safer. Remove material
only from the outside surface and
work from the heavy end of the blade
toward the tip.
2. Sharpening Screwdrivers -
The end of a properly sharpened
screwdriver will be a perfect rectan-
gle, absolutely flat and perpendicular
to the center line of the shank. The
two sides and two faces will taper
outward from the edge of the shank
of the screwdriver. They should be
flat with intersecting faces perpen-
dicular. Hold each face of the screw-
driver against the wheel to true it up,
then ease the end straight into the
stone to grind it true.
3. Sharpening Knives -
Remove metal from both faces of
most knives, working from the heavy
end of the blade toward the tip.
4. Sharpening Twist Drill Bits -
Drill bits are best sharpened on a
sharpening jig but some sharpening
can be done on your bench grinder.
Begin on one side of the point at the
existing angle, then twist the bit while
maintaining a constant angle with the
grinding surface. Sharpen only the
tip. This technique requires consider-
able practice so try it a few times with
the grinder off. Be sure to maintain
the original cutting edge angle as this
is important to maintaining the effi-
ciency of your bits.
5. To prevent accidents, turn off the tool
and disconnect its power supply after
use. Clean, then store the tool in-
doors out of children’s reach.
