3. Each graduation of the Scale (part #36) is equal to .010” (.25mm). The Planer

may be set to cut any depth between 0 - 0.7” (0 - 2mm).

4. The Scale (part #36) also features a “P” or “Park” setting, which indicates the two

Blades (part #64) are fully retracted and that the Planer may be safely set on its

base after the Blades have come to a complete stop.

To Attach The Rabbeting Width Guide:

1. Place the Rabbeting Bracket (part #65) on top of the front portion of the Rabbet-

ing Width Guide (part #66) and secure, using one Screw (part #13), Washer (part

#11), and Nut (part #27). Make sure the Washer is installed between the bottom

of the Rabbeting Bracket and the top of the Rabbeting Width Guide.

(See Figure B and Assy. Diagram.)

3. To set the rabbeting

width

, loosen the Screw (part #13) and slide the Rabbeting

Bracket (part #65) to the left or right along the Rabbeting Width Guide (part #66)

to locate the desired width. Then, retighten the Screw.

NOTE: Make sure the

Washer (part #11) is installed between the bottom of the Rabbeting Bracket and

the top of the Rabbeting Width Guide to keep the Rabbeting Bracket from slip-

ping. (See Figure B and Assy. Diagram.)

To Make A Cut:

1. Always use clamps, a vise, or other safe, practical ways to hold and support the

workpiece.

2. While standing next to the workpiece, hold the Planer firmly with both hands.

3. Place the Front Support (part #31) of the Planer on the workpiece, and squeeze

the Start Switch (part #57) to start the tool. (See Figure D.)

4. While placing pressure on the Front Support (part #31) to control the depth of the

cut, and while placing pressure on the Rabbeting Width Guide (part #66) against

the workpiece to control the width of the cut, feed the Planer

forward slowly

until

the Rear Support (part #30) contacts the workpiece. Then, transfer pressure to

the Rear Support, and continue planing

slowly

to the end of the cut.

Do not pull

the Planer back over the surface already cut.

5. If necessary, repeat Step #4 above, using progressively deeper cuts until you

near the desired depth. Then, readjust the Rabbeting Depth Guide (part #52) to

make a light cut for the final pass. (See Figure C.)

6. NOTE: The Planer’s Motor may stall if the tool is improperly used. If the Motor

begins to stall, reduce the speed at which you are making the cut and/or reduce

the depth of the cut.

To Reverse Or Replace The Cutter Blades:

1. The Planer is equipped with

two

reversible

Cutter Blades (part #64). Do not

attempt to sharpen old Blades. And always reverse or replace the Blades as a

set in order to avoid an imbalance of the Cutter (part #42). (See Figures E, F,

and Assy. Diagram.)

2. To reverse or replace the Cutter Blades (part #64), use an Allen Wrench to

loosen the three Bolts (part #62) that secure Blades and the Wedge (part #61) to

the Cutter (part #42).

3. Slide the Cutter Blades (part #64) lengthwise out of the Wedge (part #61).

NOTE: Use a piece of wood to slide the Blades out in order to avoid cuts to your

fingers.

4. Once the Cutter Blades (part #64) have been removed, clean the Blades, the

Wedge (part #61), and the Cutter (part #42) thoroughly before installing the new

Blades; thus, allowing for a more accurate Blade setting.
