CONVERSION TO HIGH-SPEED
STEEL BLADES
The 1594 Planer can be converted to accept
large HSS blades. The conversion requires the
optional PA1204 HSS Blades with Retainers
(pair). (Fig. 7)
Additional pairs of HSS blade, the PA1205
large HSS blades, can also be purchased
separately.
REMOVAL OF MINI TC BLADE
HOLDERS AND RETAINERS
1. Rotate the blade drum until the clamping jaw
is parallel to the planer shoe.
2. Loosen the three clamp screws completely
and remove the screws and clamping jaw.
3. Slightly rotate the blade drum and use a
piece of wood to push the blade, holder and
retainer off 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.
4. Rotate the blade drum 180° and repeat the
procedure to remove the second blade.
INSTALLATION OF HSS BLADES
AND RETAINERS
Before inserting a new or sharpened blade,
clean all surfaces (blades, 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 plane 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.
