21. Place the wider portion of the saw base on that
part of the workpiece which is solidly supported,
not on the section that will fall off when the cut is
made. As examples, Fig. 5 illustrates the RIGHT
way to cut off the end of a board, and Fig. 6 the
WRONG way. If the workpiece is short or small,
clamp it down. DO NOT TRY TO HOLD SHORT
PIECES BY HAND! (Fig. 5 & 6)
22. Never attempt to saw with the circular saw held
upside down in a vise. This is extremely danger-
ous and can lead to serious accidents. (Fig. 7)
23. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.
24. Do not stop the blades by lateral pressure on the
saw blade.
25. Always use blades recommended in this manual.
Do not use any abrasive wheels.
26. Wear a dust mask and hearing protection when
use the tool.
SAVE THESE INSTRUCTIONS.
WARNING:
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.
OPERATING INSTRUCTIONS
Removing or installing saw blade
CAUTION:
Always be sure that the tool is switched off and
unplugged before installing or removing the saw blade.
The following blade can be used with this tool.
Max. dia.
Min. dia.
190 mm
170 mm
The thickness of the riving knife is 1.8 mm.
CAUTION:
• Do not use saw blades which do not comply with the
characteristics specified in these instructions.
• Do not use saw blades the disc of which is thicker or
the set of which is smaller than the thickness of the riv-
ing knife.
To remove the saw blade, depress the shaft lock fully to
prevent shaft rotation, then use the hex wrench to loosen
the hex socket head bolt. (Fig. 8)
Now remove the outer flange, raise the safety cover as
much as possible, and remove the saw blade. (Fig. 9)
Install the saw blade using the reverse of the removal
procedure. Install the inner flange, saw blade, outer
flange and hex socket head bolt, in that order. Be sure to
secure the hex socket head bolt tightly. (Fig. 10)
CAUTION:
• Make sure that the blade teeth point forward in the
same direction as the tool rotation (the arrow on the
blade should point in the same direction as the arrow
on the tool).
• Use only the Makita hex wrench to remove or install the
blade.

Riving knife adjustment (Fig. 11)
Move the base and raise the safety cover. Then use the
hex wrench to loosen the hex head socket bolt for the riv-
ing knife adjustment. Move the riving knife up or down
over the two protuberances for settings indicated in the
illustration, so as to obtain the proper clearance between
the riving knife and saw blade.
CAUTION:
Ensure that the riving knife is adjusted such that:
The distance between the riving knife and the toothed rim
of the saw blade is not more than 5 mm. The toothed rim
does not extend more than 5 mm beyond the lower edge
of the riving knife.
Adjusting depth of cut (Fig. 12)
Loosen the lever on the side of rear handle and move the
base up or down. At a desired depth of cut, secure the
base by tightening the lever.
CAUTION:
• Use a shallow depth of cut when cutting thin workpiece
for cleaner, safer cuts.
• After adjusting the depth of cut, always tighten the lever
securely.
Adjusting for bevel cuts (Fig. 13)
Loosen the thumb nuts in front and back, and tilt the tool
to the desired angle for bevel cuts (0° – 45°). Secure the
thumb nuts tightly in front and back after making the
adjustment.
Sighting (Fig. 14)
For straight cuts, align the right notch on the front of the
base with your cutting line on the workpiece.
For 45° bevel cuts, align the left notch with it.
Switch action (Fig. 15)
CAUTION:
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the "OFF"
position when released.
To prevent the switch trigger from being accidentally
pulled, a lock-off button is provided.
To start the tool, depress the lock-off button and pull the
switch trigger. Release the switch trigger to stop.
Operation (Fig. 16)
Hold the tool firmly with both hands. Set the base plate
on the workpiece to be cut without the blade making any
contact. Then turn the tool on and wait until the blade
attains full speed. Now simply move the tool forward over
the workpiece surface, keeping it flat and advancing
smoothly until the sawing is completed. To get clean cuts,
keep your sawing line straight and your speed of advance
uniform.
CAUTION:
• The riving knife should always be used.
• Do not stop the saw blade by lateral pressure on the
disc.
• Retracting lever should be used only for bevel cutting
and shallow cutting such as lower guard cannot move
smoothly. Raise lower guard by Retracting Lever. As
soon as blade enters the material, retracting lever must
be released. For all other sawing, the lower guard
should operate automatically.
