4. Cutting aluminum extrusion (Fig. 31)
When securing aluminum extrusions, use spacer
blocks or pieces of scrap as shown in Fig. 31 to
prevent deformation of the aluminum. Use a cut-
ting lubricant when cutting the aluminum extru-
sion to prevent build-up of the aluminum material
on the blade.
CAUTION:
Never attempt to cut thick or round aluminum
extrusions. Thick aluminum extrusions may
come loose during operation and round alumi-
num 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
suggested 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 efficient operation. Install the set plate on
the holder as shown in Fig. 33. Align the cutting
line on your workpiece 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 fac-
tory, but rough handling may have affected the align-
ment. If your tool is not aligned properly, perform the
following:
1) 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.
2) 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 indi-
cates 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)
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,
maintenance or adjustment should be carried out by
a Makita Authorized Service Center.
