DOUBLE INSULATION FOR SAFER OPERATION
To ensure safer operation of this power tool, HITACHI has adopted a double insulation
design. “Double insulation” means that two physically separated insulation systems have
been used to insulate the electrically conductive materials connected to the power supply
from the outer frame handled by the operator. Therefore, either the symbol “ ” or the
words and “Double insulation” appear on the power tool or on the nameplate.
Although this system has no external grounding, you must still follow the normal electrical
safety precautions given in this Instruction Manual, including not using the power tool in
wet environments.
To keep the double insulation system effective, follow these precautions:
*Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble this power
tool, and only genuine HITACHI replacement parts should be installed.
*Clean the exterior of the power tool only with a soft cloth moistened with soapy water
and dry thoroughly.
*Never use solvents, gasoline or thinners on plastic components; otherwise the plastic
may dissolve.

BEFORE CUTTING
1. Positioning the table insert
[Right angle cutting] [Left bevel angle cutting] [Right bevel angle cutting]
Fig. 8-a Fig. 8-b Fig. 8-c
Table inserts are installed on the turntable. When shipping the tool from the factory, the
table inserts are so fixed that the saw blade does not contact them. The burr of the
bottom surface of the workpiece is remarkably reduced, if the table insert is fixed so that
the gap between the side surface of the table insert and the saw blade will be minimum.
Before using the tool, eliminate this gap in accordance with the following procedure.
(1) Right angle cutting
Loosen the three 5 mm machine screws, then secure the left side table insert and
temporarily tighten the 5 mm machine screws of both ends. Then fix a workpiece
(about 7-7/8" (200 mm) wide) with the vise assembly and cut it off. After aligning
the cutting surface with the edge of the table insert, securely tighten the 5 mm
machine screws of both ends. Remove the workpiece and securely tighten the 5
mm center machine screw. Adjust the right hand table insert in the same way.
(2) Left and right bevel angle cutting
Adjust the table insert in the manner shown in Fig. 8-b and Fig. 8-c following the
same procedure for right angle cutting.
CAUTION: After adjusting the table insert for right angle cutting, the table
insert will be cut to some extent if it is used for bevel angle cutting.
When bevel cutting operation is required, adjust the table insert
for bevel angle cutting.
2. Checking the saw blade lower limit position
Check that the saw blade can be lowered 23/64" to 7/16" (9 mm to 11 mm) below the
table insert as shown in Fig. 9-a.
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. 9-b)
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: Confirm that the saw
blade is adjusted so
that it will not cut into
the turntable.
3. Lower limit position of saw blade when cutting a large workpiece
NOTE: When cutting a workpiece exceeding 4-7/32" (107 mm) in height in right-
angle cutting or 2-3/4"(70 mm) in left bevel angle cutting or 1-3/4" (45 mm) in
right bevel angle cutting, adjust the lower limit position so that the base of
the motor head (see Fig. 9-a) will not come in contact with the workpiece.
To adjust the lower limit position of the saw blade, follow the procedure (1) shown in
Fig. 9-a.
䡬Lower the motor head, and turn the 8 mm depth adjustment bolt and make
adjustments so that there can be a clearance of 5/64" to 1/8" (2 mm to 3 mm) between
the lower limit position of the motor head and the top of the workpiece at the saw
blade's lower limit position where the head of the 8 mm depth adjustment bolt
contacts the hinge.
4. Confirmation for use of sub fence (A)
WARNING: In the case of right bevel cutting, turn the sub fence (A) clockwise.
Unless it is turned clockwise, the main body or saw blade may contact
the sub fence (A), resulting in an injury.

This power tool is equipped with a sub
fence (A).
In the case of direct angle cutting and
left bevel angle cutting, use the sub fence
(A). Then, you can realize stable cutting
of the material with a wide back face.
In the case of right bevel cutting, raise
the sub fence (A) up as illustrated in Fig.
10 and then turn it clockwise.
5. Confirmation for use of sub fence (B)
WARNING: In the case of left bevel cutting, turn the sub fence (B) counterclockwise.
Unless it is turned counterclockwise, the main body or saw blade
may contact the sub fence (B), resulting in an injury.
This power tool is equipped with a sub
fence (B). In the case of direct angle
cutting and right bevel angle cutting, use
the sub fence (B). Then, you can realize
stable cutting of the material with a wide
back face. In the case of left bevel cutting,
raise the sub fence (B) up as illustrated
in Fig.11 and turn it counterclockwise.
6. 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. 12-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. 12-b.
