OPERATION
WARNING!
To reduce the risk of injury, wear
safety goggles or glasses with
side shields. Unplug the tool
before changing accessories or
making adjustments.
In all cutting operations, keep the shear at
right angles to the surface of the workpiece
and the back as low as possible for fast
cutting. Use an even forward pressure to
insure efficient operation. To obtain the least
amount of metal distortion and smoothest
edge, keep waste portion of metal to the
right of the shear. Cutting line should be
lubricated before cutting 16 gauge steel or
heavier.
Blade Clearance
The clearance between the blades is not
set at the time of manufacture. Cleaner
edges and longer blade life will result when
the gap is properly set for the gauge of the
metal to be cut. Use 20% of the material
thickness for an approximate blade clear-
ance setting. Make minor adjustments, if
necessary.

* Make minor adjustments if necessary.
To adjust the gap:
1.
Unplug the tool and loosen the lower
blade clampling screw 1/3 of a turn with
the socket wrench provided.
2.
Turn the blade positioning screw,
on the side of the yoke, in or out to
decrease or increase the gap.
NOTE: If lowerblade clamping screw is
loose more than a 1/3 of a turn, the blade
clearwance may be misadjusted.
3.
Measure the clearance with the feeler
gauge provided.
4.
When the desired setting has been
achieved, tighten the blade clamping
screw and locking nut on the blade po-
sitioning screw.

Sharpening Blades
The cutting angles must be maintained.
When blade replacement is necessary al-
ways replace the blades in sets. This will
produce cuts of consistent quality.
