FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool.
Adjusting the depth of cut (Fig. 1)
6 cutting depths can be preset according to the size of biscuit to be used or if trimming the wall or ceiling panels as
explained later. Rotate the stopper until the pointer points to the appropriate size marked on the stopper.
Refer to the table below for the correspondence between the sizes marked on the stopper and the biscuit size. Fine
adjustments to the cutting depth can be made by turning the adjusting screw after loosening the hex nut. This may
become necessary after the blade has been resharpened a few times.

Angle guide (Fig. 2 & 3)
The angle guide can be moved up and down to adjust the
position of the blade in relation to the top of the work-
piece.
To adjust the angle guide height, loosen the lock lever
down and rotate the knob until the pointer points to the
desired scale graduation marked on the angle guide.
Then tighten the lock lever up to secure the angle guide.
The scale on the angle guide indicates the distance from
the top of the workpiece to the center of the blade thick-
ness.
Fence (Fig. 4 & 5)
The angle of the fence can be adjusted between 0° and
90° (positive stops at 0°, 45° and 90°). To adjust the
angle, loosen the lock lever and tilt the fence until the
pointer points to the desired graduation on the angle
scale. Then tighten the lock lever to secure the fence.
When the fence is set at 90°, both the distance from the
center of the blade thickness to the fence and the dis-
tance from the center of the blade thickness to the bot-
tom of the base are 10 mm.
Set plate (Fig. 6 & 7)
Use the set plate as shown in Fig. 6 & 7 when cutting
slots in thin workpieces.
Switch action (Fig. 8)
CAUTION:
• Before plugging in the tool, always check to see that
the slide switch actuates properly and returns to the
"OFF" position when the rear of the slide switch is
depressed.
To start the tool, slide the slide switch toward the "I (ON)"
position. For continuous operation, press the front of the
slide switch to lock it.
To stop the tool, press the rear of the slide switch, then
slide it toward the "O (OFF)" position.

ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Removing or installing the blade (Fig. 9)
CAUTION:
• When installing the cutter blade, mount the inner flange
with the side marked "22" facing toward you.
• When installing the circular saw blade, mount the inner
flange with the side marked "22" facing toward the tool.
To remove the blade, loosen the clamp screw and open
the blade cover. Push the shaft lock and loosen the lock
nut using the lock nut wrench. To install the blade, first
mount the inner flange.
Then mount the blade and the lock nut. Securely tighten
the lock nut using the lock nut wrench. Close the blade
cover and tighten the clamp screw to secure the blade
cover.
CAUTION:
• Use only Makita lock nut wrench provided to remove or
install the blade.
• Always check the depth of cut after replacing the blade.
Readjust it if necessary.
Dust bag (Fig. 10)
To attach the dust bag, fit it onto the dust nozzle. If the
dust bag becomes an obstacle to your work, turn the dust
nozzle to change the dust bag position.
When the dust bag is about half full, switch off and
unplug the tool. Remove the dust bag from the tool and
pull the bag's fastener out. Empty the dust bag by tapping
it lightly to remove as much of the dust as possible.
NOTE:
• If you connect a Makita vacuum cleaner to your plate
joiner, more efficient and cleaner operations can be
performed.
