SAFETYOPERATIONMAINTENANCE SETUP

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 rectangle, 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

perpendicular. Hold each face of the screwdriver

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 considerable 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 efficiency of your bits.

5. To prevent accidents, turn off the tool and

disconnect its power supply after use. Clean,

then store the tool indoors out of children’s reach.
