FUNCTIONAL DESCRIPTION
Please read carefully all safety rules and operating instructions. The Model KD-442 Shear is recommended for CR sheet steel up to 16 gage. Secure
work piece. To start cut, place side knives of shear slightly on the edge of the top side of the work piece to steady the tool and ready it for the cut.
Depress the trigger switch and guide shear into the work. Do not force it. Avoid double thicknesses of material which exceed the 16 gage recommended
capacity. For cutting within perimeter of work piece, drill a 1/2” diameter starting hole and follow instructions above. If resistance to tool develops or cut-
ting becomes diffi cult, discontinue cutting and check the following: lubrication; thickness of material; sharpness of cutting blades.
OPERATION
Avoid Accidental Starting
Don’t carry plugged-in tool with fi nger on switch. Be sure switch is OFF when plugging in. Use of any accessory with this power unit might increase the
hazard. The tool should be used only for the purpose for which it is designed.
Plug
THE POLARIZED PLUG IS A SAFETY FEATURE. This tool is equipped with a polarized two wire AC line plug. The two wire polarized plug (having one
blade wider than the other) will fi t into the power outlet only one way. DO NOT DEFEAT THE SAFETY PURPOSE OF THE POLARIZED PLUG, by tam-
pering with it. If the plug does not fi t you should still be unable to fully insert the plug into the socket, you may fi nd that a proper outlet is needed to meet
today’s electrical standards. An electrician will replace your outlet safely.
Extension Cords
Always check the extension cord and repair or replace if damaged.
Outdoor Use Extension Cords
When tool is used outdoors, use only extension cords marked W-A or W.
Stay Alert
Watch what you are doing, use common sense when operating a power tool. Do not use tool while tired or under the infl uence of drugs, alcohol or medi-
cation.
Check Damaged Parts
Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its
intended function. Check for alignment if moving parts, binding or moving parts, breakage of parts, mounting, and any other conditions that may affect
its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center unless otherwise indicated
elsewhere in this instruction manual. Have defective switches replaced by authorized service center. Do not use tool if switch does not turn it on or off.
DO NOT OPERATE
power tools in explosive atmospheres such as in the presence of fl ammable liquids, gases, or dust. Motors in these tools normally
spark and sparks can possibly ignite fumes.
Read all instruction.
Save these instructions.
MAINTENANCE
When servicing, use only identical replacement parts. Tool may be cleaned and lubricated by the user, but any other servicing, including the changing of
carbon brushes, should be performed by the manufacturer or any authorized representative or service station.
Cable
The cable or cord is the “life line” of your tool. Keep it clean by wiping it off occasionally. Keep it out of oils and greases. Coil it neatly when not in use
and avoid dragging it across sharp surfaces or using it as a handle to lift the tool.
When using the tool at a considerable distance from power source, an extension cable of adequate size must be used to prevent loss of power and over-
heating.
For extension cables up to 75 feet use number 18; for 100 feet use number 16; and for up to 200 feet use number 14 wire gage. If you are working with
a 230 volt fool, cable lengths may be doubled using the same wire gage sizes as prescribed above for the 120 volt tool.
Lubrication
Always disconnect KD-440 Electric Shear from power source before lubricating.
Once every three months, depending upon usage, remove the shear Head from the power unit following the instructions given on the service sheet un-
der the heading “Disassembly-To remove the shear head assembly (42-20) from the drive motor.” Put a few drops of heavy oil on the Eccentric Bearing
Assembly (40-24), so that it saturates the needle bearing (40-24- 2). Grease is even better if it can be forced or pressed into the needle bearing rollers.
The outside surface of the Eccentric Bearing Ring (40-24-3) should also be greased.
Tools that have seen continuous use should also have the gear train lubricated periodically, preferably at the same time the eccentric bearing assembly
is serviced. To lubricate the gears remove the screws that hold the gear case to the motor shell. Remove the gear case from the cover plate and wipe
out the old grease with a cloth. Wash the gears and spindles with kerosene or cleaning fl uid. Refi ll the gear case ONLY 1/3 FULL with a good standard
gear grease. Never fi ll more than 1/3. The Ball bearing in the gear case is a closed type bearing. It has been permanently lubricated at the factory to last
the life of the bearing. This bearing should NEVER be immersed in a solvent or cleaning fl uid.
Adherence to these maintenance instructions will greatly increase the life of your Model KD-442 Electric Shear, so it will give you long and satisfactory
service.
