retainer and drum) with mineral spirits;
lacquer thinner or alcohol, as this will
ensure an accurate blade setting and
proper tool performance.
New or re-sharpened planer blades must
be properly leveled before installation
using the optional PA1206 HSS Blade
Leveling Fixture. (The PA1204 HSS
Blades with Retainers are leveled at the
factory.)
To ensure proper operation and an even
cut, the blades must be positioned so
that they are:
• Centered relative to the front and
rear shoes.
• Aligned with each other.
• Positioned so that they will not touch
against any part of the planer when
rotated.
Procedure:
1. To install the blades, carefully
slide the blade/retainer assembly
sideways to over one of the two
clamping areas on the blade drum. The
retainer must engage in the groove. (Fig.
8)
2. Place a properly-oriented clamping
jaw over the blade. (Fig. 4)
3. Tighten the three clamp screws
with the Torx key using the correct
tightening sequence (1, 2, 3). (Fig. 4)
4. Rotate the blade drum 180° and
repeat the procedure for the second
blade clamp.
▼ REMOVING LARGE HSS BLADES
To remove the blades:
1. Rotate the blade drum until the
clamping jaw is parallel to the planer
shoe.
2. Loosen and remove the three clamp
screws with the Torx key.
3. Also remove the clamping jaw.
4. Slightly rotate the blade drum and
use a piece of wood to push the
blade and retainer sideways and out
of the blade drum. Make sure to keep
your fingers away from the sharp
edges of the blade. If the blade is
gummed and difficult to remove, you
may clean the blade and clamp with
mineral spirits, lacquer thinner or
alcohol.
Rotate the blade drum 180° and repeat
the procedure to remove the second
blade.

▼ RESHARPENING HSS BLADES
Worn or dull HSS planer blades can be
resharpened. The optimal blade angle of
50° should be maintained when
sharpening. Once a total of 6 mm of
steel has been removed from tips of the
blades, both blades must be replaced
because the minimum HSS blade height
is 23 mm from back to tip.
▼ LEVELING OF HSS BLADES
A PA1206 HSS Blade Leveling Fixture
(optional accessory) is required to level
new or resharpened HSS blades. (Not
necessary with the PA1204 HSS Blades
and Retainers, which are leveled at the
factory.)
1. Place the blade and blade retainer on
the leveling fixture and make sure
that the blade retainer engages in the
grooves intended for this purpose.
