4. Check performance of lower guard
WARNING
Make absolutely sure that the lower guard is not
fi xed. Also, check and see if it can move smoothly.
If the saw blade is kept exposed, injury can result.
The lower guard (refer to Fig. 1) serves to protect
your body from coming into contact with the saw
blade. Make absolutely certain that the cover
smoothly performs to cover the saw blade. If the
lower guard should not move smoothly, never use it
without repairing it.
In such a case, get in touch with the store where
you bought the circular saw or the HITACHI
AUTHORIZED SERVICE CENTER for necessary
repair.
5. Check for proper operation of the brake
This circular saw features an electric brake that
functions when the switch is released. Before using
the circular saw, ensure that the electric brake
functions properly. If it does not, bring the tool to a
HITACHI AUTHORIZED SERVICE CENTER.
6. Adjusting the cutting depth (Fig. 8)
WARNING
If the lever is loose, injury can result. Tighten it
securely after adjustment.
To adjust cutting depth, loosen the lever and, while
holding the base with one hand, move the main body
up and down to obtain the prescribed cutting depth.
After adjusting to the prescribed cutting depth,
tighten the lever securely.

inclined gauge, the saw blade may be inclined to a
maximum angle of 50° in relation to the base. Always
insure that the wing-nut is thoroughly tightened after
making the desired adjustment.

NOTE
Values of the inclined gauge provided on the base
merely serve as a rough guideline. For cutting
operation at an inclined precise angle, use the
circular saw after adjusting the angle between the
base and the saw blade with a protractor, etc.
8. Prepare a wooden work bench (Fig. 10)
Since the saw blade will extend beyond the lower
surface of the lumber, place the lumber on a work
bench when cutting. If a square block is utilized as
a work bench, select level ground to ensure it is
properly stabilized. An unstable work bench 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.
9. Check battery insertion
WARNING
If the battery is inserted while the power switch
is in the ON position, the power tool will start
operating immediately, inviting serious accident.
