Guard Against Electric Shock

Prevent body contact with grounded surfaces, for example: pipes, radiators, ranges, refrigerator enclosures.

Keep Children Away

Do not let visitors contact tool or extension cord. All visitors should be kept away from work area.

Store Idle Tools

When not in use, tools should be stored in dry, high or locked-up place out of reach of children.

Don’t Force Tool

It will do the job better and safer at the rate for which it was designed.

Use Right Tool

Don’t force a small tool to do the job of a heavy duty tool. Don’t use tool for on purpose not intended, for example-don’t use a circular saw for cutting tree

limbs or logs.

Dress Properly

Do not wear loose clothing or jewelry. They can be caught in moving parts. Rubber gloves and footwear are recommended when working out doors.

Wear protective hair covering to contain long hair.

Use Safety Glasses

Use safety equipment. Always wear eye protecion.

Don’t Abuse Cord

Never carry tool by cord or yank it to disconnect from receptacle. Keep cord from heat, oil, and sharp edges. Replace damaged cords immediately.

Secure Work

Use clamps or vise to hold work. It’s safer than using your hand and it frees both hands to operate tool.

Don’t Overreach.

Keep proper footing and balance at all times.

Maintain Tools with Care

Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing center blades and side knives. Inspect tool

cords periodically and if damaged, have repaired by authorized service facility. Inspect extension cords periodically and if damaged or replace. Keep

handles dry, clean, and be free from oil and grease.

Disconnect Tools

When not in use; before servicing; when changing Center Blades, Side Knives, Brushes, etc.

Remove Adjusting keys and Wrenches

Form Habit of checking to see that keys and adjusting wrenches are removed from tool before turning it on.

OPERATION

Avoid Accidental Starting

Don’t carry plugged-in tool with ﬁnger 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 ﬁt 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 ﬁt you should still be unable to fully insert the plug into the socket, you may ﬁnd 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-Aor 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 inﬂuence 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 ﬂammable liquids, gases, or dust. Motors in these tools normally

spark and sparks can possibly ignite fumes.

Read all instruction.

Save these instructions.

FUNCTIONAL DESCRIPTION

Please read carefully all safety rules and operating instructions. The Model KM-440 Shear is recommended for CR sheet steel up to 14 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 14 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 difﬁcult, discontinue cutting and check the following: lubrication; thickness of material; sharpness of cutting blades.

Motor

Be sure your power supply agrees with nameplate marking. Use Alternating Current Only (50 to 60 Cycles), 120 volts. Voltage variation of more than

10% will cause loss of power and overheating. Motors are factory tested. If this shear does not operate, check the following: supply line for blown fuses;

plug and receptacle for contact. This tool will stop when the brushes wear to a preset length. Damage to the motor is thus avoided.

DISASSEMBLY: To remove the shear head from the

motor loosen three cap screws (92-28). Remove shear

head from motor by pulling head ﬁrmly forward. Slight

tapping with a mallet may be required if head does not

slide off easily.

To remove cutter blades from shear head remove

three cap screws (92-28) from shear housing (40-23).

Be careful not to lose rear spacer bushing (60-27) when

removing the middle cap screw. Remove center blade

(40-21) from shear housing by tapping blade gently rear-

ward. Be careful not to lose spacer bushing (40-27) from

hole in center blade. Side knives (60-22L and 60-22R)

will now drop out of the shear housing.

To remove eccentric bearing assembly (40-24)

from shaft use an appropriate wrench to loosen eccen-

tric nut by turning counter clockwise.

ASSEMBLY: To install eccentric bearing assembly (40-

24) onto shaft, make sure the large thin washer (60-25)

is ﬁrst inserted over the shaft. Screw eccentric bear-

ing assembly on to shaft and tighten with appropriate

wrench. Lubricate bearing with a good grade of bearing

grease.

To install cutter blades into shear housing (40-23)

place the side knives (60-22L and 60-22R) into position

in the shear housing (40-23). Insert center cap screw

(92-28) through the side knives (60-22L and 60-22R)

with rear spacer bushing (60-27) between them and

start cap screw into thread just enough to hold blades in

place. DO NOT TIGHTEN. Insert spacer bushing (40-

27) into hole in center blade (40-21) and lubricate with

Molybdenum Disulﬁde grease (264-2) or equivalent.

Install center blade into shear housing by tapping blade

gently forward using a drift to line up hole in center blade

with forward holes in housing. Insert and tighten forward

cap screw (92-28) making sure spacer bushing (40-27)

in center blade stays in position. Apply Molybdenum

Disulﬁde grease (264-2) or equivalent to clevis or yoke

in center blade where it rides on the eccentric bearing

assembly. Insert rear cap screw (92-28) into shear hous-

ing, but do not completely tighten.

To install shear head assembly onto drive motor

make sure all cap screws (92-28) are loosened about

three or four complete turns. Spread shear housing

(40-23) slightly using a spreader (drift) near the rear cap

screw (92-28). Place shear head onto unit, tap left side

knife rearward as far as it will go, and tighten cap screws

to 40-45 inch pounds. It may be necessary to gently tap

the shear head into place if it does not readily slip onto

the nose of the power unit.

WARNING: THE KETT TOOL CO. CANNOT ASSUME RESPONSIBLITY FOR DAMAGE TO OR

MALFUNCTION OF A KETT SHEAR HEAD USED IN COMBINATION WITH ANY DRILL OTHER

THAN THOSE REGULARLY SUPPLIED BY US.

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 KM-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 (40-20) 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 ﬂuid. Reﬁll the gear case ONLY 1/3 FULL with a good standard

gear grease. Never ﬁll 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 ﬂuid.

Adherence to these maintenance instructions will greatly increase the life of your Model KM-440 Electric Shear, so it will give you long and satisfactory

service.
