PRIOR TO OPERATION

CAUTION
Make all necessary adjustments before inserting the
plug in the power source.
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specifi ed on the product
nameplate.
Do not use with direct current, or transformers such as
boosters. Doing so may result in damage or accidents.
2. Power switch
Ensure that the power switch is in the OFF position. If the
plug is connected to a receptacle while the trigger switch
is in the ON position, the power tool will start operating
immediately, inviting serious accident.
3. Extention cord
When the work area is removed from the power source,
use an extension cord of suffi cient thickness and rated
capacity. The extension cord should be kept as short as
practicable.
4. Remove all packing
connected to the tool before attempting to operate
it.
5. Releasing the locking pin (Fig. 3)
When the power tool is prepared for shipping, its main
parts are secured by a locking pin.
Move the handle slightly so that the locking pin can be
disengaged.
During transport, lock the locking pin into the gear case.
6. Attach the dust bag to the main unit (Fig. 1)
7. Installation (Fig. 4)
Ensure that the machine is always fi xed to bench.
Attach the power tool to a level, horizontal work bench.
Select 8 mm diameter bolts suitable in length for the
thickness of the work bench.
Bolt length should be at least 40 mm plus the thickness
of the work bench.
For example, use 8 mm × 65 mm bolts for a 25 mm thick
work bench.
8. Base holder adjustment (Fig. 5)
Loosen the 6 mm bolt with the supplied 10 mm box
wrench. Adjust the base holder until its bottom surface
contacts the bench or the fl oor surface.
After adjustment, fi rmly tighten the 6 mm bolt.

9. Check to see that the lower guard operates
smoothly
CAUTION
This slide compound miter saw is equipped with a saw
head lock as safety device.
(1) When you push down the handle, check that the lower
guard revolves smoothly (Fig. 6).
(2) Next, check that the lower guard returns to the original
position when the handle is raised.
10. Oblique angle
Before the power tool is shipped from the factory, it is
adjusted for 0°, right angle, left 45° bevel cutting angle
and right 45° bevel cutting angle with the 8 mm set
screw, 8 mm bolt (A) and 8 mm bolt (B).
When changing the adjustment, change the height of
the 8 mm set screw, 8 mm bolt (A), or 8 mm bolt (B) by
turning them.
When changing the bevel angle to the right 45°, pull the
set pin (A) on the direction shown in Fig. 7-b and incline
the motor head to the right.
When adjusting the motor head to 0°, always return the
set pin (A) to its initial position as shown in Fig. 7-b.
11. Checking the saw blade lower limit position
Check that the saw blade can be lowered 9 mm to
10 mm below the table insert.
When you replace a saw blade with a new one, adjust
the lower limit position so that the saw blade will not cut
the turntable or complete cutting cannot be done.
To adjust the lower limit position of the saw blade, follow
the procedure (1) indicated below. (Fig. 8)
Furthermore, when changing the position of a 8 mm
depth adjustment bolt that serves as a lower limit position
stopper of the saw blade.
(1) Turn the 8 mm depth adjustment bolt, change the height
where the bolt head and the hinge contacts, and adjust
the lower limit position of the saw blade.
NOTE
Confi rm that the saw blade is adjusted so that it will not
cut into the turntable.

PRIOR TO CUTTING

1. Cutting a groove on the guard
Holder (A) has a guard (see Fig. 10) into which a groove
must be cut when using the tool for the fi rst time. Loosen
the 6 mm knob bolt to retract the guard slightly.
After placing a suitable wooden piece to sit on the
fence and the table surfaces, fi x it with the vise. Slide
the motor head backwards to the end. Then tighten the
slide securing knob. After the switch has been turned on
and the saw blade has reached maximum speed, slowly
lower the handle to cut a groove on the guard. (See
Fig. 19)
CAUTION
Do not cut the groove too quickly; otherwise the guard
might become damaged.
Do not use slide cutting for grooving tasks.
