procedure in reverse.
WARNING:
BE SURE TO TIGHTEN THE HEX
BOLT SECURELY. Also be careful not to tighten
the bolt forcibly. Slipping your hand from the hex
wrench can cause a personal injury.
WARNING:
If the inner flange is removed, be sure
to install it on the spindle. When installing, choose a
correct side on which protrusion fits into the circular
saw blade hole perfectly. Mounting the circular saw blade
on the wrong side can result in the dangerous vibration.
Blade guard cleaning
When changing the circular saw blade, make sure to
also clean the upper and lower guards of accumulated
metal chips as discussed in the Maintenance section.
Such efforts do not replace the need to check lower
guard operation before each use.

malfunctions or fires.
When you wish to perform clean cutting operation, connect a
Makita vacuum cleaner to your tool by using lid for vacuum cleaner.

OPERATION
This tool is intended to cut mild steel. With appropriate Makita
genuine saw blades, following materials can also be sawed:
• Fiber-cement board
• Wood
Refer to our website or contact your local Makita dealer
for the correct circular saw blades to be used for the
material to be cut.
CAUTION:
Always wear eye protection or
goggle before operation.
CAUTION:
Be sure to move the tool forward
in a straight line gently. Forcing or twisting the tool
will result in overheating the motor and dangerous
kickback, possibly causing severe injury.
CAUTION:
Never twist or force the tool in the
cut. This may cause motor overload and/or a danger-
ous kickback, resulting in serious injury to the operator.
CAUTION:
Always use the circular saw blades
appropriate for your job. The use of inappropriate
circular saw blades may cause a poor cutting perfor-
mance and/or present a risk of personal injury.
CAUTION:
Do not use a deformed or cracked
circular saw blade. Replace it with a new one.
► Fig.21
Hold the tool firmly. The tool is provided with both a front grip
and rear handle. Use both to best grasp the tool. If both hands
are holding the tool, they cannot be cut by the circular saw
blade. Set the base on the workpiece to be cut without the cir-
cular saw blade making any contact. Then turn the tool on and
wait until the circular saw blade attains full speed. Now simply
move the tool forward over the workpiece surface, keeping it
flat and advancing smoothly until the cutting is completed.
To get clean cuts, keep your cutting line straight and your
speed of advance uniform. If the cut fails to properly follow
your intended cut line, do not attempt to turn or force the
tool back to the cut line. Doing so may bind the circular saw
blade and lead to dangerous kickback and possible serious
injury. Release switch, wait for the circular saw blade to
stop and then withdraw tool. Realign tool on new cut line,
and start cut again. Attempt to avoid positioning which
exposes operator to chips and particles being ejected from
the tool. Use eye protection to help avoid injury.
