CAUTION:
• When performing the bevel cut with the workpiece
secured on the left side of the turn base, it will cre-
ate a condition where the piece cut off will come to
rest on the blade. If the blade is raised while the
blade is still rotating, this piece may be caught in
the blade, causing fragments to be scattered
around which is dangerous. The blade should be
gently raised only after the blade has come to a
complete stop.
• When pressing down the handle, apply pressure in
parallel with the blade. If a force is applied perpen-
dicularly to the turn base or if the pressure direc-
tion is changed during a cut, the precision of the
cut will be impaired.
• Always set the sub-fence to the left position as
shown in Fig. 17 when performing bevel cuts.
3.
Compound cutting
Compound cutting can be performed at angle shown
in the table below.
Bevel angle
45°
When performing the compound cutting, refer to
"Miter cutting" and "Bevel cut" explanations.
4.
Cutting aluminum extrusion (Fig. 31)
When securing aluminum extrusions, use spacer
blocks or pieces of scrap as shown in Fig. 31 to pre-
vent deformation of the aluminum. Use a cutting
lubricant when cutting the aluminum extrusion to
prevent build-up of the aluminum material on the
blade.
CAUTION:
Never attempt to cut thick or round aluminum extru-
sions. Thick aluminum extrusions may come loose
during operation and round aluminum extrusions
cannot be secured firmly with this tool.
5.
Wood facing (Fig. 32)
Use of wood facing helps to assure splinter-free cuts
in workpieces. Attach a wood facing to the guide
fence using the holes in the guide fence.
CAUTION:
• Use straight wood of even thickness as the wood
facing.
• See Fig. 32 concerning the dimensions for a sug-
gested wood facing.
6.
Cutting repetitive lengths (Fig. 33)
When cutting several pieces of stock to the same
length, ranging from 240 mm to 400 mm, use of the
set plate (optional accessory) will facilitate more effi-
cient operation. Install the set plate on the holder as
shown in Fig. 33. Align the cutting line on your work-
piece with either the left or right side of the groove in
the kerf board, and while holding the workpiece from
moving, move the set plate flush against the end of
the workpiece. Then secure the set plate with the
screw. When the set plate is not used, loosen the
screw and turn the set plate out of the way.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Adjusting the cutting angle
This tool is carefully adjusted and aligned at the factory,
but rough handling may have affected the alignment. If
your tool is not aligned properly, perform the following:
1)
2)
Miter angle
Left and right
0° – 45°
Replacement of carbon brushes
(Fig. 39 & 40)
Replace carbon brushes when they are worn down to the
limit mark. Both identical carbon brushes should be
replaced at the same time.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
Miter angle (Fig. 34 & 35)
Loosen the grip and set the turn base at zero
degrees by turning the turn base. Tighten the grip
securely and loosen the hex bolts on the guide
fence. Square the side of the blade with the face of
the guide fence using a triangular rule, try-square,
etc. by moving the right side of the guide fence.
Then securely tighten the hex bolts on the guide
fence in the order indicated in Fig. 35.
Bevel angle
i) 0° bevel angle
Loosen the lever at the rear of the tool. Loosen
the hex nut and turn the hex bolt (A) two or three
revolutions clockwise so that the blade tilts to the
right. (Fig. 36)
Lower the handle fully and square the side of the
blade with the top surface of the turn base using
the triangular rule, try-square, etc. by turning the
hex bolt (A) counterclockwise. Then tighten the
hex nut to secure the hex bolt (A). (Fig. 37)
Make sure that the pointer on the arm indicates
0° on the bevel scale on the arm holder. If the
pointer does not indicate 0°, loosen the screw
securing the pointer and adjust the pointer.
(Fig. 38)
ii) 45° bevel angle
Adjust 45° bevel angle only after performing 0°
bevel angle adjustment. To adjust 45° bevel
angle, loosen the lever and tilt the saw blade to
the left fully. Make sure that the pointer on the
arm indicates 45° on the bevel scale on the arm
holder. If the pointer does not indicate 45°, turn
the hex bolt (B) on the side of the arm until the
pointer indicates 45°. (Fig. 38)
