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. Refer to some
examples below for proper and improper settings.
(A) Front base (Movable shoe)
(B) Rear base (Stationary shoe)

Connecting a vacuum cleaner (Fig. 10)
A nozzle and joint (optional accessories) are necessary
to connect a Makita vacuum cleaner to your tool. Consult
a Makita catalogue or representative on the nozzle and
joint.
Nozzle assembly (optional accessory) (Fig. 11)
Use of the special nozzle assembly will minimize chip
scatter, making for a cleaner work area.
Install the nozzle assembly (optional accessory) on the
tool using the screw as shown in Fig. 11.
Planing operation (Fig. 12)
First, rest the tool front base flat upon the workpiece sur-
face without the blades making any contact. Switch on
and wait until the blades attain full speed. Then move the
tool gently forward. Apply pressure on the front of tool at
the start of planing, and at the back at the end of planing.
Planing will be easier if you incline the workpiece in sta-
tionary fashion, so that you can plane somewhat down-
hill. The speed and depth of cut determine the kind of
finish. The power planer keeps cutting at a speed that will
not result in jamming by chips. For rough cutting, the
depth of cut can be increased, while for a good finish you
should reduce the depth of cut and advance the tool
more slowly.

Shiplapping (Rabbeting) (Fig. 13, 14, 15 & 16)
To make a stepped cut as shown in Fig. 13, use the edge
fence (guide rule).
Draw a cutting line on the workpiece. Insert the edge
fence into the hole in the front of the tool. Align the blade
edge with the cutting line.
Adjust the edge fence until it comes in contact with the
side of the workpiece, then secure it by tightening the
screw.
When planing, move the tool with the edge fence flush
with the side of the workpiece. Otherwise uneven planing
may result.
CAUTION:
• The blade edge should be made to protrude outside
slightly (0.3 mm – 0.6 mm). Otherwise, nicks and gen-
erally poor shiplapping results.
Chamfering (Fig. 17 & 18)
To make a chamfering cut as shown in Fig. 17, align the
"V" groove in the front base with the edge of the work-
piece and plane it.
Although this side view cannot show it,
the edges of the blades run perfectly
parallel to the rear base surface.
Cause: One or both blades fails to
have edge parallel to rear
base line.
Cause: One or both blade edges fails
to protrude enough in relation
to rear base line.
Cause: One or both blade edges
protrudes too far in relation to
rear base line.
