Adjusting the depth of cut (Fig. 1)

Loosen the wing bolt on the depth guide and move the
base up or down. At the desired depth of cut, secure the
base by tightening the wing bolt.

CAUTION:

• After adjusting depth of cut, always tighten the wing

bolt securely.

Sighting (Fig. 2)

Align the edge of the front of the base with your cutting
line on the workpiece.

Switch action

the switch trigger actuates properly and returns to the
“OFF” position when released.

Hex wrench storage (Fig. 4)

When not in use, store the hex wrench as shown in the
figure to keep it from being lost.

ASSEMBLY

CAUTION:

• Always be sure that the tool is switched off and

unplugged before carrying out any work on the tool.

Removing or installing diamond wheel
(optional accessory)

CAUTION:

• Use only the Makita wrench and hex wrench to install

or remove the wheel.

(Fig. 5)

To remove the wheel, hold the outer flange with the
wrench and loosen the hex bolt clockwise with the hex

wrench. Then remove the hex bolt, outer flange and
wheel.

(Fig. 6)

To install the wheel, follow the removal procedure in
reverse. Always install the wheel so that the arrow on the
wheel points in the same direction as the arrow on the
blade case. BE SURE TO TIGHTEN THE HEX BOLT
COUNTERCLOCKWISE SECURELY.

OPERATION

CAUTION:

• THIS TOOL SHOULD ONLY BE USED ON

HORIZONTAL SURFACES.

• Be sure to move the tool forward in a straight line and

gently. Forcing and exerting excessive pressure or
allowing the wheel to bend, pinch or twist in the cut can
cause overheating of the motor and dangerous
kickback of the tool.

(Fig. 7)

Hold the tool firmly. Set the base plate on the workpiece to
be cut without the wheel making any contact. Then turn
the tool on and wait until the wheel attains full speed. Now
simply move the tool forward over the workpiece surface,
keeping it flat and advancing smoothly until the cutting is
completed. Keep your cutting line straight and your speed
of advance uniform.

When using a curving diamond wheel
(Accessory)

WARNING:

Failure to follow the following warnings may result in
serious injury.

• Mount the diamond wheel on the spindle of the tool

making sure that the direction of arrow on the surface
of the diamond wheel matches the direction of the
arrow on the blade case of the tool.

• Always wear the safety goggles or safety glasses.
• The rated speed of the diamond wheel must be at least

equal to the maximum speed marked on the power
tool. Diamond wheels running faster than their rated
speed can break and fly apart.

• Before each use, make sure with hands and eyes that

the diamond wheel has no deformation, cracks, chips,
breaking, or abnormal tear and wear on the cutting
edge and the body of the diamond wheel.

• Stop using the diamond wheel once you find such

abnormal signs.

• Perform cuts according to the shape of the curving
