Tips to Easier, Safer Cutting

a. When heavy cutting is involved, it is less strenuous to hold one handle of the tool on the ground using foot pressure. This permits the cutting force to be applied to the upper handle, makes the cutting position less awkward, and utilizes body weight. This allows more power to be transferred to the cutting edges.

b. Use the correct cutting tool for the type, size, and hardness of the metal to be cut.

c. Keep cutter jaws at right angles to piece being cut. Cutting diagonally may twist jaws d. Do not twist or pry with tool while cutting.

e. Do not exceed the full cut on a material whose hardness is unknown. Test hardness with slow pressure to see if material is being cut. The size of the metal you are cutting is not as important as its hardness.

f.

Do not exceed the cutter capacity that is marked on the jaw of the tool or its rating capacity in this catalog.

g. Keep jaw bolts tight and joints oiled at all times.

h. Maintain the original jaw bevel angles when sharpening out of line or chip cutting edges.

Safety Do’s and Dont’s

Wear your gloves and safety glasses at all times!

Do wear safety shoes.

Do remove oil or grease from your hands, from tools and from the floor and area where you will be working.

Do remember that metal flies when cut. The harder the metal, the farther it will fly.

Do warn those in the area when you intend to use a cutter and protect your fellow workers from flying metal.

Do use all tools as recommended.

Don’t attempt to use a cutting tool, hand or power, until you fully understand its use.

Don’t forget that metals may fly and cause injury.

Don’t use cutters for any application except those listed in this catalog.

Don’t use H.K. Porter cutters on energized circuits, wire, or cable.

Safety Precautions

DANGER

Indicates a high probability that death, severe bodily injury or major property damage could result.

Hard metals may snap off or fly through the air when cut. Always wear safety glasses and warn workers nearby to prevent them from being injured from flying metal.

To prevent injury from flying metal, take precautions such as wrapping a cloth or rag around the cutting jaws so metal pieces can not fly.

WARNING

Is serious but less inevitable. There is some probability that death, severe bodily injury or property damage could result.

CAUTION

Is less serious but still demands attention. Indicates a hazard which may result in minor injury or property damage.

The "Safety Alert Symbol" symbol to the left is used to call attention to instructions concerning personal safety. Watch for this symbol, it points out important safety precautions. It means: “ATTENTION! Stay alert, personal safety may be in danger!”

Read the message that follows this symbol and be alert to the possibility of personal injury or death resulting from misuse.

The use of any industrial tool may present hazards which can result in serious injury or death. The H.K.Porter

® tools listed in this catalog are not exceptions to this rule.

1. What is the material to be cut?

(See above chart)

2. What size is the material to be cut?

Capacities of all hand-operated cutters are shown opposite each catalog listing. Power tool capacities are shown in the Power Tool Selector chart. Do not exceed listed capacities.

3. How hard is the material to be cut?

Many of the materials illustrated in the chart above are made in varying degrees of hardness. The maxmum hard ness ratings that each hand and power tool is designed to cut are shown under each tool in this catalog.

Extra Hard Metals:

Up to Brinell 455/Rockwell C48

Hard Metals:

Up to Brinell 400/Rockwell C42

Medium Hard Metals:

Up to Brinell 300/Rockwell C31

Soft Metals:

Up to Brinell 200/Rockwell C15

4. Will numerous or few cuts be made in a day?

The frequency of cuts to be made should be taken into consideration when choosing a cutter. HKP manufacturers inexpensive hand cutters for light-duty work, heavy-duty cutters for tougher jobs, and hydraulic and pneumatic cutters for extremely hard materials and production cutting.

WIRE, ELECTRIC WROUGHT IRON

5. Is speed a factor in the cutting?

Choose the proper cutter to fit the job requirements, whether an occasional cut is called for or fast, continuous, industrial production cutting.

NOTE: PROVIDE ANSWERS TO AS MANY OF THE

QUESTIONS AS POSSIBLE.

WARNING

• Always wear safety glasses/goggles when cutting.

• Cut in a safe area; consider the safety of others in the immediate area.

• The harder the material being cut, the likelier it is to become airborn during cutting.

• Use tools correctly! (Refer to “Engineering Information” section of this catalog)

• Use the correct tool for the work being performed.

• Maintain tools, power supplies, and hoses in safe working condition.

DANGER

Never use any H.K. Porter cutters on energized circuits, wire, or cable.

CUTTERS

Quality Features of H.K. Porter

HANDLES CLOSER

TOGETHER

More cutting power with less strain.

CUTTING JAWS

Alloy tool steel, drop forged, precision ground for maximum wear resistance and longer cutting life

LOCKPLATE

Prevents jaw bolts from turning or loosening. Eliminates

“sloppy” head, insures trouble-free operation.

SIMPLE

ADJUSTMENT

One adjustment realigns cutting edges properly.

TOGGLE JOINT

STEEL TUBULAR

HANDLES

Greater strength, lighter weight.

RUBBER GRIPS

Easy on the hands.

Firmer grip for user safety.

There are four basic jaw designs. They are engineered to give long, trouble-free life and the most efficient cutting of the materials which they are designed to cut.

1

ANGULAR JAWS

30° offset jaws have clipper-cut blades, designed for cutting close or flush to a surface.

Cuts soft or medium-hard material.

2

ALL-PURPOSE

JAWS

Can have centeror clipper-cut blades used for broad cutting applications.

Jaw Designs

3

SHORT-NOSED

JAWS

Center-cut, carbide-tipped blades for cutting hard- and nonalloy chains and padlock hasps.

4

HEAVY-DUTY

STRAP JAWS

Straps keep the cutting edges aligned under the most demanding applications.

Four different cutting blade styles are available for specific types or broad ranges of cutting applications.

1

CENTER-CUT

BLADES

Slightly rounded cutting edges, beveled on both sides, broaden cutting applications.

3

SHEAR-CUT

DANGER

Cutting Blades

2

CLIPPER-CUT

BLADES

Blades are beveled on only one side for smooth flush cuts that are close to workpiece.

4

END-CUT BLADES

Blades are at right angles to handles for easier handling and “head-on” close cutting of materials.

ENGINEERING INFORMATION

Ordering Replacement Parts

Order replacement parts through your Cooper Tools Distributor. Care should be taken to give accurate information regarding part numbers and descriptions. Include model numbers and serial numbers, as well. Although all parts are available at the factory, we suggest customers stock spare blades, seals, filters and oil for minimum delay in maintaining their units.

Factory Repair Service

HKP units may be returned to factory for repair and reconditioning at any time. A free inspection and estimate of repair charges will be supplied if requested. All returns must be made by prepaid transportation.

How to Sharpen Cutter Jaws

• Remove nicks in jaws by filing straight across cutting edges

• On jaws with equal bevels, file equally from each bevel, keep file flat against bevel

• On jaws with one large bevel, file on that bevel, small bevel must also be restored

• Jaws should not be razor sharp

• Approximately 1/64" (.4mm) should remain flat to form strong, durable edge

• Adjust tool according to the instructions below

• To sharpen shear-cut blades (blades that pass each other like scissors) remove nicks by filing straight across cutting edges

• Finish by running a flat file over inner jaw surface to remove burrs

How to Adjust the Cutter Jaws

• An adjustment screw is located on the cutter handle above the toggle joints

• If jaw edges are too far apart with handles closed, tighten adjusting screw, this brings cutting edges together

• Cutting edges should be 1/64" (.4mm) apart for longest jaw life

• Oil all joints

• If jaw edges are too close together with the handles apart, loosen adjusting screw until it disappears from the narrow slot in the handle

• Make a cut with the tool in this position (cut will force the slot inward)

• Try to close the handles. If they do not close completely and jaw edges are 1/64" (.4mm) apart, tighten adjusting screw to meet the handle on far side of slot

• Oil all joints

• If jaws are too far apart with handles closed after making cut with adjusting screw backed off, tighten adjusting screw as explained above

• To sharpen shear-cut blades (blades that pass each other, like scissors), remove nicks by filing straight across the cutting edges

• Finish by running a flat file over inner blade surface to remove burrs.
