Removing or installing planer blades

Important:

• Always be sure that tool is switched off and

unplugged before removing or installing the blade.

• Use the following planer blades.

Part Nos. 793004-6 793007-0 793322-2

*P-04260 *P04276 *P-04282

Center when purchasing blades.

For tool with standard planer blades

(Fig. 1, 2 & 3)

To remove the blades on the drum, unscrew the three

installation bolts with the socket wrench. The drum

cover comes off together with the blades.

To install the blades, first clean out all chips or foreign

matter adhering to the drum or blades. Use blades of

the

same

dimensions

oscillation/vibration will result, causing poor planing

action and, eventually, tool breakdown.

Place the blade on the gauge base so that the blade

edge is perfectly flush with the inside edge of the

gauge plate. Place the adjust plate on the blade, then

simply press in the heel of the adjust plate flush with

the back side of the gauge base and tighten two

screws on the adjust plate. Now slip the heel of the

adjust plate into the drum groove, then fit the drum

cover on it. Tighten the three installation bolts evenly

and alternately with the socket wrench.

For tool with mini planer blades (Fig. 1, 4 & 5)

1. Remove the existing blade, if the tool has been in

use, carefully clean the drum surfaces and the

drum cover. To remove the blades on the drum,

unscrew the three installation bolts with the socket

wrench. The drum cover comes off together with

the blades.

2. To install the blades, loosely attach the adjust

plate to the set plate with the pan head screws

and set the mini planer blade on the gauge base

so that the cutting edge of the blade is perfectly

flush with the inside flank of the gauge plate.

drum

3. Set the adjust plate/set plate on the gauge base

so that the planer blade locating lugs on the set

plate rest in the mini planer blade groove, then

press in the heel of the adjust plate flush with the

back side of the gauge base and tighten the pan

head screws.

4. It is important that the blade sits flush with the

inside flank of the gauge plate, the planer blade

locating lugs sit in the blade groove and the heel

of the adjust plate is flush with the back side of the

gauge base. Check this alignment carefully to

ensure uniform cutting.

5. Slip the heel of the adjust plate into the groove of

the drum.

6. Set the drum cover over the adjust plate/set plate

and screw in the three hex flange head bolts so

that a gap exists between the drum and the set

plate to slide the mini planer blade into position.

The blade will be positioned by the planer blade

locating lugs on the set plate.

7. The blade's lengthwise adjustment will need to be

manually positioned so that the blade ends are

clear and equidistant from the housing on one

side and the metal bracket on the other.

8. Tighten the three hex flange head bolts (with the

socket wrench provided) and hand rotate the

drum to check clearances between the blade ends

and the tool body.

9. Check the three hex flange head bolts for final

tightness.

10. Repeat procedures 1 – 9 for other blade.

For shiplapping (Fig. 11)

The blade edge should be made to protrude outside

slightly (0.3 mm – 0.6 mm). Otherwise, nicks and

generally poor shiplapping results.

CAUTION:

Tighten the blade installation bolts carefully when

attaching the blades to the tool. A loose installation

bolt can be dangerous. Always check to see they are

tightened securely.
