G9003 Portable Planer -9 -
The Blade must be completely removed
from the Planer and from the Back Plate in
order for it to be safely sharpened. Follow
the preceding instructions for Blade
Removal.
For the best results, have planer blades
sharpened by a professional sharpening
service which has the grinding and mea-
surement equipment to assure that the
blade cutting geometry is maintained at
optimum levels. It is a procedure which
requires special equipment and precision,
otherwise, a set of blades can be easily
ruined. Knives should always be ground as
a set so that an equal amount of material is
removed which will maintain the balance of
the cutterhead.
The blades can be tuned up between
major sharpenings using the Sharpening
Jig supplied. Remove both Blades com-
pletely from the Planer.
To Sharpen Blades:
1. Separate the Blade from the Back
Plate by removing two Phillips ®
head screws.
2. Mount the two Blades onto the
Sharpening Jig as shown in
Figure 6.
BLADE SHARPENING
Planer blades are dangerously sharp.
Use extreme caution when inspecting,
removing, sharpening, or replacing
blades into the cutterhead. Substantial
risk of laceration injury exists!

3. The bevel edge of the blades will
extend beyond the sloped edge of
the Jig. The blades can be sharp-
ened by sweeping a fine metal file
along the two edges, using the
existing bevel angle as a guide. Or
the entire Jig can be turned face
down on a sharpening stone and
swept across the surface of the
stone.
4. Remove the Blades from the Jig
and reinstall into the Planer.
Blade sharpness is one of the most impor-
tant factors in getting good results with the
planer. Take care to ensure that the work-
piece being planed is free from grit, dirt, or
nails or other embedded metals such as
staples. These can nick or chip the knives
and can require a complete regrinding.
