Cutting Operation for Long Blade Life | Hitachi CR 13VA manual

7-4. Cutting Operation for Long Blade Life

The service life of a saw blade may vary depending on the operating conditions such as the type of cutting action, pressing force, etc. Observing the following instructions can lengthen the service life of a saw blade, for reference.

1 Move the saber saw handle up and down repeatedly during the cutting operation

The service life of a saw blade can be lenghtened by moving the saber saw handle up and down repeatedly once or twice per second during the cutting operation as shown below.

Do not apply undue force to the workpiece. Appropriate pressing force is about 4 kgf (8.8 lbs.).

The cutting edge contacts the pipe in a seesaw motion.

< Explanation >

Heat generated in the cutting operation can significantly affect the service life of the saw blade. Continued cutting operation with the saw blade heated to red hot can decrease the hardness of the saw blade because the cutting edge is annealed. The saw blade is then worn out in a short time and nothing can be cut. The merits of moving the saber saw up and down are described below.

1The seesaw motion of the saw blade can minimize heating.

2The effective cutting length of the blade is longer than that of an ordinary cutting operation. Thus, the service life of the saw blade can be lengthened and the cutting speed becomes faster. Cutting wood in the same manner can also make the cutting speed faster.

2 Do not apply undue force to the workpiece

Application of undue force to the workpiece during the cutting operatation can heat up the saw blade and the number of strokes can decrease, causing reduction of speed. Appropriate pressing force is about 4 kgf (8.8 lbs.).
