BEFORE USE
1. Check the work area environment
Check the work area to make sure that it is clear of debris and clutter.
Clear the area of unnecessary personnel. Ensure that lighting and ventilation is adequate.
2. Check if saw blade is tightened
While the saw blade is tightened securely for immediate use when it is assembled at the
factory, be sure to check it out again for caution's sake. A bolt can be tightened when it
is turned clockwise. Use the provided box wrench to check it out.
For further details, refer to the item of [MOUNTING AND DISMOUNTING THE SAW
BLADE] on Page 26.
3. Check if wing nut is tightened
If the wing nut to adjust cutting depth (Fig. 10) is loose, injury can result. Make sure that
it is tightened securely.
4. Check performance of lower guard
WARNING:
The lower guard (refer to Fig. 3) 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 battery insertion
WARNING:
CAUTION: Until the battery locks in place with a little click, if not, it may accidentally
fall out of the tool causing injury to you or someone around you.
6. 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.
Make absolutely sure that the lower guard is not fixed. Also, check and
see if it can move smoothly. If the saw blade is kept exposed, injury can
result.
If the battery is inserted while the power switch is in the ON position,
the power tool will start operating immediately, inviting serious acci-
dent.
