Cutterhead
Whetting Knives:
After considerable use, the knives will become dull and it won’
t be
able to do job accurately. Unless badly damaged by running into
metal or other hard material, they may be sharpened as follows:
1.
DISCONNECT THE MACHINE FROM POWER SOURCE.
2.
Use a fine carborundum stone; cover it partly with paper as
indicated as shown in Fig. 21 to avoid marking the table.
3.
Lay the stone on the infeed table, lower the table and turn the
cutterhead forward until the stone lies flat on the bevel of the
knives as shown.
4.
Hold the cutterhead from turning, and whet the beveled edge
of the knife, stroking lengthwise by sliding the stone back
and forth across the table.
5.
Do the same amount of whetting on each of the three blades.

Blade Care
When blades become dull enough so that it is noticeable when
cutting, they should be resharpened. A sharp blade works easier and
results in longer blade life. The penalty paid for a dull blade is less
blade life; poor finish and wear on all parts of the machine.
When the knives cannot be properly retouched as described in
"Whetting Knives", they must be ground for a sharp edge without
nicks.
IF THE JOINTER IS USED OFTEN KEEP A SPARE SET OF
BALADES ON HAND AT ALL TIMES.
Gum and pitch which collets on the blades cause excessive friction
as the work continuous, resulting in over heating the blades, less
efficient cutting, and consequently loss of blade life. Use "Gum and
Pitch Remover"to wipe off the blades.
MAINTENANCE
In time rust may appear on the table and fence and other parts of the
jointer, resulting in less efficiency and accuracy of the machine.
Use paste wax which can be applied to prevent rust formation. If,
however, rust has already formed on these parts, use "Rust
Remover"which will restore the machine to its original accuracy
when applied.
LUBRICATION
The cutterhead runs in two single rows sealed and shielded ball
bearings, which are pre-lubricated for their entire life.
