Maintenance; Adjusting The Cutting Angle - Makita LS1212 Instruction Manual

7. Wood facing
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 and 6 mm screws.
See the figure concerning the dimensions for a
suggested wood facing. (Fig. 31)
CAUTION:
• Use straight wood of even thickness as the wood
facing.
• When cutting workpieces from 107 mm to 120 mm
high, use a wood facing to prevent a portion of the
workpiece near the guide fence from being left uncut.
Example:
When cutting workpieces 120 mm high, use a wood facing
with the following thickness.
Miter angle
0°
Left and Right 45°
Right 60°
C00010
8. Cutting repetitive lengths (Fig. 32)
When cutting several pieces of stock to the same
length, ranging from 300 mm to 470 mm, use of the set
plate (optional accessory) will facilitate more efficient
operation. Install the set plate on the holder (optional
accessory) as shown in the figure.
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.
NOTE:
• Use of the holder-rod assembly (optional accessory)
allows cutting repetitive lengths up to 2,200 mm
approximately.
9. Groove cutting (Fig. 33)
A dado type cut can be made by proceeding as follows:
Adjust the lower limit position of the blade using the
adjusting screw and the stopper arm to limit the cutting
depth of the blade. Refer to "Stopper arm" section
described previously.
After adjusting the lower limit position of the blade, cut
parallel grooves across the width of the workpiece
using a slide (push) cut as shown in the figure. Then
remove the workpiece material between the grooves
with a chisel. Do not attempt to perform this type of cut
using wide (thick) blades or with a dado blade. Possible
loss of control and injury may result.
CAUTION:
• Be sure to return the stopper arm to the original
position when performing other than groove cutting.
Carrying tool (Fig. 1)
Make sure that the tool is unplugged. Secure the blade at
0° bevel angle and the turn base at right miter angle fully.

you fully. Lower the handle fully and lock it in the lowered
position by pushing in the stopper pin.
Carry the tool by holding both sides of the tool base as
shown in the figure. If you remove the holders, dust bag,
etc., you can carry the tool more easily. (Fig. 34)
CAUTION:
• Always secure all moving portions before carrying the
tool.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.

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. Mitre angle (Fig. 35)
Push the carriage toward the guide fence and tighten
the knob to secure the carriage.
Loosen the grip which secures the turn base. Turn the
turn base so that the pointer points to 0° on the miter
scale. Then turn the turn base slightly clockwise and
counterclockwise to seat the turn base in the 0° miter
notch. (Leave as it is if the pointer does not point to 0°.)
Loosen the hex bolts securing the guide fence using
the socket wrench.
Lower the handle fully and lock it in the lowered
position by pushing in the lock pin. Square the side of
the blade with the face of the guide fence using a
triangular rule, try-square, etc. Then securely tighten
the hex bolts on the guide fence in the order from the
left side. (Fig. 36)
Make sure that the pointer indicates 0° on the mitre
scale. If the pointer does not indicate 0°, loosen the
screw securing the pointer and adjust the pointer.
(Fig. 37)
2. Bevel angle
(1) 0° bevel angle (Fig. 38)
Push the carriage toward the guide fence and
tighten the knob to secure the slide poles. Lower the
handle fully and lock it in the lowered position by
pushing in the lock pin. Loosen the lever at the rear
of the tool. Make sure that the arm is locked.
Turn the hex bolt on the left side of the arm two or
three revolutions counterclockwise. Turn the hex
bolt on the right side of the arm two or three
revolutions counterclockwise to tilt the blade to the
left. (Fig. 39)
Carefully 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 on the right
side of the arm clockwise. Turn the hex bolt on the
left side of the arm clockwise as far as it will go.
Then tighten the lever securely. (Fig. 40)
Make sure that the two pointers on the arm point to
each 0° on the bevel scale on the arm holder. If they
do not point to 0°, loosen the screws which secure
