Sharpening Cutter Blades - Craftsman 113.20680 Owner's Manual

The normal position of guard (at REST) when fence is
stationed at MAXIMUM WIDTH OF CUT, is shown as
"position "A" NEVER ROTATE GUARD BEYOND
POSITION "B'" BECAUSE THIS WOULD EXERT EX-
CESSIVE TENSION ON SPRING WHICH COULD
WEAKEN OR BREAK IT.
Check operation of GUARD and SPRING,
1. With fence in MAXIMUM WtDTH OF CUT position,
pass a piece of 1/4 in, thick wood on edge (jointing
position) over cutterhead.
2. The guard should return automatically to its REST
position against the fence when free of the wood.
3, If guard does not return to its REST position, remove
cotter pin from pivot pin and remove guard. Check
pivot pin and hole o.. make sure there are no burrs,
rust, or other foreign matter.
4. Apply a few drops of SAE No. 20 or No. 30 engine
oil to pivot pin.
5, Replace guard and cotter pin.
If guard still does not return to its REST position, con-
suit your local Sears Retail Store before using3 the
jointer-planer.

SHARPENING CUTTER BLADES
The blades can be honed individually with an ordinary
oilstone,
Make sure your oilstone is not worn in the center. It
must be flat,
Be sure to remove the burr on the fiat side.
If the blades are nicked, they must be replaced or re-
ground. They can be reground several times until they
become 9/t6 in. wide. Never install reground blades less
than 9/16 in, wide.
Have your knives reground by someone who is com-
petent. Look in the "Yellow Pages" of your telephone
directory ... see "Sharpening Services".
