OPERATING INSTRUCTIONS

Removing or installing planer blades
(Fig. 1, 2 & 3)
Important:
• Always be sure that tool is switched off and
unplugged before removing or installing the blade.
• Use the following planer blades.
Part Nos. 793186-4 *P-04254
Blades with * mark are available in European coun-
tries only. Consult your dealer or the Makita Service
Center when purchasing blades.
To remove the blades on the drum, unscrew the five
installation bolts with the hex 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 and weight, or drum oscillation
/vibration will result, causing poor planing action and
eventually tool breakdown.
There are two adjusting screws for each blade. When
installing the blade, the notch in the blade should fit
over the head of the adjusting screw. Then fit on the
drum cover and secure the five bolts only finger-tight.
For the correct planer blade setting
Your planing surface will end up rough and uneven, unless the blade is set properly and securely. The blade
must be mounted so that the cutting edge is absolutely level, that is, parallel to the surface of the rear base.
Below are some examples of proper and improper settings.
(A) Front base (Movable shoe)
(B) Rear base (Stationary shoe)

Turn the drum until the blade edge is right in the
middle between the front and rear bases.
Place the triangular rule flat on the rear base and run
it out over and across the blade edge. Turn the two
adjusting screws to adjust the blade protrusion. The
blade setting should be made so that the protrusion
will be uniform all the way across. Thus the triangular
rule should be flush with the entire width of the blade
edge. After adjusting both blades, tighten the five
installation bolts evenly and alternately with the hex
wrench.
After tightening the bolts, secure the adjusting screws
fully.
CAUTION:
Tighten the blade installation bolts carefully when
attaching the blades to the tool. A loose installa-
tion bolt can be dangerous. Always check to see they
are tightened securely.
Although this side view cannot show
it, the edges of the blades run
perfectly parallel to the rear base
surface.
