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 
Fig.3 
The angle guide can be moved up and down to adjust 
the position of the blade in relation to the top of the 
workpiece. 
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 
thickness. 
 
Fence 
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 base 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. 
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. Reajust 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
