2. Adjusting the angle of inclination
By loosening the wing bolt at the scale, the saw blade
can be titled up to maximum angle of 45° against the
base (Fig. 3).
The angle of inclination can also be regulated by
loosening the wing bolt at the scale (Fig. 3).
CAUTION
It is very hazardous to allow this wing bolt to remain
loosened. Always thoroughly clamp it.
3. Regulating the guide
The cutting position can be regulated by moving the
guide to the left or right after loosening its wing bolt.
The guide can be mounted on either the left or the
right side.
4. Fine tuning of parallelism
It is possible to fine-tune the parallelism of the saw
blade to the base using the parallelism adjustment
screw.
Adjustment has already been made at the time of
shipment from the factory. However, in the unlikely
event of parallelism being faulty, adjust as follows.
(1) Unfasten only the mounting screws of the saw
cover hinge portion (Fig. 4).
Do not unfasten the sleeve screws.
(2) Retract the protective cover into the saw cover.
(3) Insert wood chip in the rear side of the saw blade
base, and mark the position on the base (Fig. 5).
(4) Move the marked wood chip to the front of the
base, and turn the parallelism adjustment screw
so that the marking corresponds to the base side
(Fig. 6).
(5) After adjustment, fasten the mounting screws
tightly in place.
NOTE
Parallelism may be slightly faulty if the cutting depth
is adjusted after parallelism adjustment.
Never unfasten the sleeve screws. Doing so may
result in loss of the sleeve and loosening of the saw
cover portion.
CUTTING PROCEDURES
1. Place the saw body (base) on the lumber, and align
the cutting line with the saw blade at the front scale
(Fig. 7).
2. Turn ON the switch before the saw blade contacts the
lumber. The switch is turned ON when the trigger is
squeezed, and turned OFF when the trigger is
released.
CAUTIONS
Prior to cutting operation, make sure the material you
are going to cut. If the material to be cut is expected to
generate harmful / toxic dusts, make sure the dust bag or
appropriate dust extraction system is connected with
dust outlet tightly.
Wear the dust mask additionally, if available.
Before starting to saw, confirm that the saw blade
has attained full-speed revolution.
Should the saw blade stop or make an abnormal
noise while operating, promptly turn OFF the switch.
Always take care in preventing the power cord from
coming near to the revolving saw blade.
Using the circular saw with the saw blade facing
upwards or sideways is very hazardous. Such
uncommon applications should be avoided.

CAUTION
To avoid serious accident, ensure the switch is in the
OFF position, and the power source is disconnected.

After having attached the saw blade, reconfirm that the
lock lever is firmly secured in the prescribed position.

MAINTENANCE AND INSPECTION

1. Inspecting the saw blade
2. Inspecting the mounting screws
3. Maintenance of the motor
4. Inspecting the carbon brushes
When cutting materials, always wear protective
glasses.
When finished with a job, pull out the plug from the
receptacle.

diameter of the saw blade and the concave side of
Washer (B) must be fitted to the saw blade sides.
* Washer (A) is supplied for 2 types of saw blades
with the hole diameters of 20 mm and 30 mm.
(When buying the Circular Saw, one type of
washer (A) is supplied.)
In case the hole diameter of your saw blade does
not correspond to that of washer (A), please
contact the shop where you purchased the Circular
Saw.

retaining the saw blade as much as possible. Then
depress the lock lever, lock the spindle, and
thoroughly tighten the bolt.
Since use of a dull saw blade will degrade efficiency
and cause possible motor malfunction, sharpen or
replace the saw blade as soon as abrasion is noted.
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so could result in serious hazard.
The motor unit winding is the very "heart" of the
power tool.
Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
For your continued safety and electrical shock
protection, carbon brush inspection and replacement
on this tool should ONLY be performed by a Hitachi
Authorized Service Center.
