NOTE:
• Use a dry cloth to wipe the dirt off the lens of lamp. Be
careful not to scratch the lens of lamp, or it may lower
the illumination.
• Do not use gasoline, thinner or the like to clean the lens
of lamp. Using such substances will damage the lens.
Hook
CAUTION:
• Always remove the battery when hanging the tool with
the hook.
• Never hook the tool at high location or on potentially
unstable surface.
The hook is convenient for hanging the tool temporarily.
To use the hook, simply turn it until it snaps into the open
position.
When not in use, always turn the hook until it snaps into
the closed position. (Fig. 17)
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out any
work on the tool.
Removing or installing saw blade
CAUTION:
• Be sure the blade is installed with teeth pointing up at
the front of the tool.
• Use only the Makita wrench to install or remove the
blade.
To remove the blade, press the shaft lock so that the
blade cannot revolve and use the wrench to loosen the
hex bolt clockwise. Then remove the hex bolt, outer flange
and blade. (Fig. 18 & 19)
To install the blade, follow the removal procedure in
reverse. BE SURE TO TIGHTEN THE HEX BOLT
COUNTERCLOCKWISE SECURELY.
When changing blade, make sure to also clean the upper
and lower blade guards of accumulated sawdust as
discussed in the Maintenance section. Such efforts do not
replace the need to check lower guard operation before
each use.
For tool with the inner flange for other than 15.88 mm
hole-diameter saw blade
CAUTION:
• Make sure that the protrusion "a" on the inner
flange that is positioned outside fits into the saw
blade hole "a" perfectly. Mounting the blade on the
wrong side can result in the dangerous vibration.
(Fig. 20)
The inner flange has a certain diameter protrusion on one
side of it and a different diameter protrusion on the other
side. Choose a correct side on which protrusion fits into
the saw blade hole perfectly.
Next, mount the inner flange onto the mounting shaft so
that the correct side of protrusion on the inner flange
faces outward and then place saw blade and outer flange.
BE SURE TO TIGHTEN THE HEX BOLT
COUNTERCLOCKWISE SECURELY.
For tool with the inner flange for a 15.88 mm hole-
diameter saw blade (country specific) (Fig. 21 & 22)
Mount the inner flange with its recessed side facing
outward onto the mounting shaft and then place saw
blade (with the ring attached if needed), outer flange and
hex bolt.
BE SURE TO TIGHTEN THE HEX BOLT
COUNTERCLOCKWISE SECURELY.
WARNING:
• Before mounting the blade onto the spindle, always
be sure that the correct ring for the blade's arbor
hole you intend to use is installed between the
inner and the outer flanges. Use of the incorrect
arbor hole ring may result in the improper mounting of
the blade causing blade movement and severe
vibration resulting in possible loss of control during
operation and in serious personal injury.
Hex wrench storage (Fig. 23)
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.
Connecting a vacuum cleaner (Optional
accessory in some countries) (Fig. 24 &
25)
When you wish to perform clean cutting operation,
connect a Makita vacuum cleaner to your tool.
Install the dust nozzle on the tool using the screw. Then
connect a hose of the vacuum cleaner to the dust nozzle
as shown in the figure.
For tool without dust nozzle provided as a standard
equipment, replace the lever fixed on the lower guard to
the one supplied with the dust nozzle (optional accessory)
at the same time when installing the dust nozzle.
Otherwise you will not be able to make a cut because the
lower guard movement is hindered by the dust nozzle.
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.
• Always use a front grip and rear handle and firmly hold
the tool by both front grip and rear handle during
operations. (Fig. 26)
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 saw, they cannot be cut by the
blade. Set the base 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. 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 blade and
lead to dangerous kickback and possible serious injury.
Release switch, wait for blade to stop and then withdraw
tool. Realign tool on new cut line, and start cut again.
