7-4. Blade Service Life

Blade replacement and service life are described in the Handling Instruction as illustrated in Fig. 4 below. The
service life described is approximate and is based on straight line cutting of 1.6 mm [1/16"] mild steel plate
material with an even, clean surface. Less favorable cutting conditions may cause the service life of the blade to
be slightly shortened.

Instruct the customer in the following techniques so that
most efficient cutting operations can be achieved.
When cutting thin workpieces (1 mm [.039"] or less) with
a hand shear, the main body of the tool should be kept
parallel with the surface of the workpiece. However,
when cutting thicker workpieces (more than 1 mm
[.039"]), the procedures described below will ensure
smooth and efficient cutting operations.
(1) As illustrated in Fig. 2, the tail portion of the main
body of the tool should be lifted slightly when the cut-
off side of the workpiece is on the left side of the tool.
(2) As illustrated in Fig. 3, the tail portion of the main
body of the tool should be lowered slightly when the
cut-off side of the workpiece is on the right side of the
tool.
