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 groove 
Fig.1 
6 grooving depths can be preset according to the size of 
biscuit to be used. 
Refer to the table below for the correspondence 
between the sizes marked on the stopper and the biscuit 
size. Fine adjustments to the grooving 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 
The angle guide height can be moved up and down to 
adjust the position of the blade in relation to the top of 
the workpiece. 
Fig.2 
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. 
Fig.3 
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 
thickness. 
The angle guide is removable from the fence according 
to the need of your work. To remove the angle guide, 
loosen the lock lever and turn the knob clockwise until it 
comes out of the upper end of the fence. 
Fence 
 
NOTE: 
• Remove the angle guide according to the need of 
your work when using the tool with the angle of the 
fence adjusted to other than 0 ゚. When you need to 
use the angle guide under the above condition, be 
sure to adjust the depth of groove to get a proper 
depth. 
Fig.4 
Fig.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 
distance from the center of the blade thickness to the 
bottom of the blade cover are 10 mm. 
Set plate

Use the set plate as shown in the figures 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. 
• Switch can be locked in "ON" position for ease of 
operator comfort during extended use. Apply 
caution when locking tool in "ON" position and 
maintain firm grasp on tool. 
To start the tool, slide the slide switch toward the "I (ON)" 
position. For continuous operation, press the front of the

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 plate joiner blade, mount the 
inner flange with the side marked "22" facing 
toward you. 
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 groove after replacing 
the blade. Reajust it if necessary.
