ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and
•
unplugged before carrying out any work on the
tool.
Blade inspection
Before using the tool, check the blades for wear. Dull,
worn blades will result in poor shearing action, and the
service life of the tool will be shortened.
The service life of the blades varies in terms of the
materials to be cut and the fixed blade clearance.
Roughly speaking, a blade can cut about 500 m (1500
ft.) of 3.2 mm (10 ga.) mild steel with one cutting edge
(total 2,000 m (6560 ft.) with four cutting edges).
Rotating or replacing blades
Both the upper and lower blades have four cutting
edges on each side (the front and back). When the
cutting edge becomes dull, rotate both the upper and
the lower blades 90° to expose new cutting edges.
When all eight edges are dull on both the upper and
lower blades, replace both blades with new ones. Each
time blades are rotated or replaced, proceed as follows.

After securing the upper blade, be sure that there is no
gap left between the upper blade and the beveled
surface of the blade holder.

Then install the lower blade like the upper blade while
adjusting the clearance between the upper blade and
lower blades. When performing this adjustment, the
upper blade should be in the lowered position.

First, semi- tighten the lower blade securing bolt, then
insert the thickness gauge for the desired clearance.
The cutting thickness is indicated on the thickness
gauge so the combinations shown in the table below
should be used. Work the lower blade positioning bolt
on the yoke until the clearance is such that the
thickness gauge moves only with some difficulty. Then
firmly tighten the lower blade securing bolt. Finally,
tighten the hex nut to secure the lower blade positioning
bolt.
