○  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 (38), always face 

the stamped side up. In the case of a 3 or 4 tooth 

blade (37), 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.

  When sharpening blade it is important to maintain 

an original shape of radius at the base of the 

tooth to avoid cracking.

Below you will fi nd some general maintenance 

instructions. For further information please contact 

your Hitachi dealer.

undamaged and that it can be securely fi tted.

○ Check that nuts and screws are suffi  ciently 

tightened.

spring.
