WARNING!
Common sense and caution are factors which cannot
be built into any product. These factors must be
supplied by the operator. Please remember:
1. Stay alert. Never operate equipment
or use tools if you are tired.
2. Do not use this product if under the influence
of alcohol or drugs. Read warning labels
on prescriptions to determine if your
judgement or reflexes might be impaired.
3. Do not wear loose clothing or jewelry as
they can be caught in moving parts.
4. Nonskid footwear is recommended.
5. Wear restrictive hair covering to contain long hair.
6. Use eye protection. Always wear ANSI-approved
safety glasses when using equipment or tools.
7. Keep proper footing and balance at all times.
Work Area Precautions
To avoid risk of personal injury, equipment damage,
fire and shock, make sure your work area is:
1. Free of damp, wet or rainy conditions.
2. Free of children. Children should never
handle tools or operate equipment.
3. Make sure your work area is well lighted.
4. Clean and uncluttered work spaces contribute
to safe and productive work conditions.
Before Operating
Check for alignment and binding of all moving
parts, broken parts or mounting fixtures and any
other condition that may affect proper operation.
Any part that is damaged should be properly
repaired or replaced by a qualified technician.
Operation Precautions
1. Never force the tool or attachment to
do the work of a larger industrial tool.
It is designed to do the job better and more
safely at the rate for which it was intended.
2. Never use the blades if they are dull, worn,
or chipped. Blades must be sharpened,
repaired or replaced before using.
3. Check to make sure all bolts are secure but
not overtightened. Check for blade clearance.
Make sure clearance is suitable for the workpiece.
4. While being used, the lower blade must be
secured with the Clamp. When not being used,
the Clamp (10) can be loosened.
Assembly Instructions
Assemble the Handle (6) over the exposed shaft
of the Geared Handle (4) and tighten Bolt (5).
Operation Instructions
1. Adjust the clearance between the Upper Blade (14)
and Lower Blade (8). To decrease the clearance,
turn the Adjusting Bolts (15) clockwise. To increase
clearance, turn the bolts counterclockwise.
The clearance can be adjusted to between
1/4 and 1/10 of the thickness of the workpiece.
2. To gain power and control of the workpiece,
start all cuts at the heel of the blades. Circular
and irregular cuts are made by turning the
workpiece while following through with
the downward stroke of the blade.
3. When a cut has been finished, push the
workpiece forward while raising the handle
to lift the blade above the workpiece.
Start the next cut at the heel of the blade.
4. Always keep the material being cut
flat on the bed of the shear.
Maintenance Instructions
Periodically use a good graphite oil to lubricate blade
edges and gears on the Geared Handle (4).
