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.

4. Extension cord
When the work area is far away from the power source, use an extension cord of sufficient
thickness and rated capacity. The extension cord should be kept as short as practicable.
WARNING: Damaged cord must be replaced or repaired.
5. Prepare a wooden workbench (Fig. 5)
Since the saw blade will extend beyond the
lower surface of the lumber, place the lumber
on a workbench when cutting. If a square block
is utilized as a workbench, select level ground to
ensure it is properly stabilized. An unstable
workbench will result in hazardous operation.
CAUTION:
To avoid possible accident, always ensure that
the portion of lumber remaining after cutting is
securely anchored or held in position.
6. Check the receptacle
If the receptacle only loosely accepts the plug, the receptacle must be repaired. Contact
a licensed electrician to make appropriate repairs.
If such a fautly receptacle is used, it may cause overheating, resulting in a serious hazard.

ADJUSTING THE SAW PRIOR TO USE
1. Adjusting the cutting depth (Fig. 6, Fig. 7)
To adjust cutting depth, loosen the clamp lever
and, while holding the base with one hand,
move the main unit up and down to obtain the
prescribed cutting depth. Inch scale on the saw
cover and metric scale on the link provide a
general guide to cutting depth. After adjusting
to the prescribed cutting depth, tighten the
clamp lever securely.
2. Adjusting the angle of inclination
As shown in Fig. 8 by loosening the wing-bolt
on the inclined gauge, the saw blade may be
inclined to a maximum angle of 45° in relation
to the base. Always insure that the wing-bolt is
thoroughly tightened after making the desired
adjustment.
3. Regularing the guide (Rip fence)
.......................................... Optional Accessory
The cutting position can be regulated by moving
the guide to the left or right after loosening its
wing-bolt. The guide may be mounted on either
the right or left side of the tool. (See Fig. 9)
CUTTING PROCEDURES
CAUTION:
Recheck that the saw blade is securely clamped.
Confirm that the clamp lever for adjusting the
cutting depth, the wing-bolt for adjusting the
angle of inclination.
Grip the saw as shown in Fig. 2 and be sure the
cord is free to move through the entire cut
without jamming or getting in the path of the
saw blade.
1. Place the saw body (base) on the lumber, and as
in Fig. 10 align the intended line of cut with the
saw blade, using the notch at the front of the
base. This relationship of base to lumber should
remain unchanged regardless of the inclination
of the base.
2. The switch should be turned to the ON position
before the saw blade comes into contact with
the lumber. The switch is turned ON when the
trigger is pulled by ones finger, and is turned
OFF when the trigger is released.
