Maintaining maximum cutting
capacity
► Fig.7: 1. Gear housing 2. Hex nut 3. Adjusting bolt
► Fig.8: 1. Top surface of turn base 2. Periphery of
blade 3. Guide fence
This tool is factory adjusted to provide the maximum
cutting capacity for a 355 mm saw blade.
When installing a new blade, always check the lower
limit position of the blade and if necessary, adjust it as
follows:
First, unplug the tool. Lower the handle completely.
Loosen the hex nut at the rear of the gear housing. Use
a screwdriver to turn the adjusting bolt until the periph-
ery of the blade extends slightly below the top surface
of the turn base at the point where the front face of the
guide fence meets the top surface of the turn base.
With the tool unplugged, rotate the blade by hand while
holding the handle all the way down to be sure that
the blade does not contact any part of the lower base.
Re-adjust slightly, if necessary.
After adjusting, tighten the hex nut with the wrench
while carefully holding the adjusting bolt in position with
the screwdriver.
At this time, make sure that the handle can be locked in
the lowered position by turning the handle latch. If the
handle cannot be locked so, turn the adjusting bolt so
that the handle can be locked in the lowered position.
CAUTION:
• After installing a new blade, always be sure that
the blade does not contact any part of the lower
base when the handle is lowered completely.
Always do this with the tool unplugged.
Adjusting the miter angle
► Fig.9: 1. Pointer 2. Lock lever 3. Miter scale 4. Grip
Loosen the grip by turning counterclockwise. Turn the
turn base while pressing down the lock lever. When you
have moved the grip to the position where the pointer
points to the desired angle on the miter scale, securely
tighten the grip clockwise.
CAUTION:
• When turning the turn base, be sure to raise the
handle fully.
• After changing the miter angle, always secure
the turn base by tightening the grip firmly.
Fence plate
The fence plate is designed to prevent smaller cutting
scraps from jamming inside the blade case. The fence
plate moves right or left automatically as the turn base
is rotated.
Switch action
CAUTION:
• Before plugging in the tool, always check to see
that the switch trigger actuates properly and
returns to the "OFF" position when released.
WARNING:
• NEVER use tool without a fully operative switch
trigger. Any tool with an inoperative switch is
HIGHLY DANGEROUS and must be repaired
before further usage.
For tool with lock-off button
► Fig.10: 1. Lock-off button 2. Switch trigger
CAUTION:
• When not using the tool, remove the lock-off
button and store it in a secure place. This pre-
vents unauthorized operation.
• Do not pull the switch trigger hard without press-
ing in the lock-off button. This can cause switch
breakage.
To prevent the switch trigger from being accidentally
pulled, a lock-off button is provided. To start the tool,
press in the lock-off button and pull the switch trigger.
Release the switch trigger to stop.
WARNING:
• For your safety, this tool is equipped with a
lock-off button which prevents the tool from
unintended starting. NEVER use the tool if it
runs when you simply pull the switch trigger
without pressing the lock-off button. Return tool
to a Makita service center for proper repairs
BEFORE further usage.
• NEVER tape down or defeat purpose and func-
tion of lock-off button.
For tool without lock-off button
► Fig.11: 1. Switch trigger
Switch on the tool and wait until the blade attains full
speed. Then lower the blade gently into the cut.
To start the tool, simply pull the switch trigger. Release
the switch trigger to stop.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the
tool.
Installing or removing saw blade
CAUTION:
• Always be sure that the tool is switched off and
unplugged before installing or removing the
blade.
• Use only the Makita socket wrench provided to
install or remove the blade. Failure to do so may
result in overtightening or insufficient tightening
of the hex bolt. This could cause an injury.
