Blade
WARNING
○ Use a sharp blade. A dull blade is more likely to snag and
thrust. Replace the fastening nut if it is damaged and hard to
tighten.
○ When replacing blade, purchase one recommended by Hitachi,
with a 25.4 mm (one inch) fi tting hole.
○ When installing a saw blade, always face the stamped side up.
In the case of a 2 tooth blade, it can be used on either side.
○ Use the correct blade for the type of work.
○ When replacing blades, use appropriate tools.
○ When cutting edges become dull, re-sharpen or fi le as shown
in the illustration. Incorrect sharpening may cause excessive
vibration.
○ Discard blades that are bent, warped, cracked, broken or
damaged in any way.
NOTE
When sharpening blade it is important to maintain an original
shape of radius at the base of the tooth to avoid cracking.
