Piranha 7a-1 0 Operators/Owner's Manual
2. lntroduction
The Piranha Shear is a heavy steel constructed, high performance hydraulic powered machine that
provides you several important advantages surpassing most other shears in today's market. The
Piranha's single hydraulic cylinder and mechanical linkage system providei the following
advantages: 1. The upper shear blade moves parallel to the lower blade thus providing maximuri
blade life, 2. Full length gibbs guide the ram laterally and front-to-back at itt ti-". during the
shearing process thus increasing rigidity, shearing accuracy, and blade life, 3. The straightJine
shearing action improves shearing accuracy in all metal thickness.
The machine is fully assembled requiring only hydraulic oil and electrical power to become fully
operational. The heavy steel "C" frames, interlocking cross memb"rs, ra-, and bed provide thl
rigidity and resistance to deflection that is necessary for accurate performance. State-of-the-art,
maintenance-free, aerospace bearings provide high load capacity and low friction in the form of a
thin walled sleeve. They are completely non-metallic and require no lubrication.
Other standard features include: Full length hardened slides with non-metallic ways, hydraulic
hold downs with replaceable polyurethane shoes, heavy duty, inch/mm motorized, disaipearing
back gauge with Go-To features and .100" retract feature on each stroke. A 53" squaring arm wit[
recessed inctr/mm scale, four-edge high chrome, high carbon shear blades top and bottom.
Proper understanding and application of the information and procedures given in this manual will
aid in establishing a preventative maintenance program and provide issistance for correcting
malfunctions that may occur in the machine. The repair parts list provides information for pai
procurement and assembly breakdowns to aid in disassembly and re-assembly for repair parts
installation. Please have machine serial number available when contacting the factory for seivice
or repair parts.

4.1.4. Up Button
The up button will raise the ram from any position to the full up position
4.1.5. Cut Length Selector Switch
The cut length selector switch controls the stroke depth of the ram. Shortening the
ram stroke permits rapid shearing of shorter material.
4.1.6. Mode Selector Switch
The run mode selector switch permits three operating modes:
Single: The ram will descend when the footswitch is depressed and will pause when
the footswitch is released at any point during the down stroke. The shear ram will
complete only one cycle in this mode. The footswitch must be reactivated to begin a
new shearing cycle.
Jog: During a shear cycle, the ram will stop when the footswitch is released.
Continuous: The ram will cycle continuously when the footswitch is depressed.
Releasing the footswitch during the down stroke will cause the ram to stop, releasing
the footswitch during the upstroke will not affect the retum stroke of the ram.
4.1.7. Shadow Light Switch
The shadow light switch will turn on lights that cast a shadow line onto the material
being sheared. il
