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 the punch and die. Inspect tool cords peri-
odically 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 punches, dies, 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 KL-2020 Nibbler is recommended for CR sheet steel up to 14 gauge. Secure
work piece. To start cut, place die opening onto the edge of the work piece to steady the tool and ready it for the cut. Depress the trigger switch and
guide nibbler into the work. Do not force it. Avoid double thicknesses of material which exceed the 14 gauge recommended capacity. For cutting within
perimeter of work piece, drill a 9/16” diameter starting hole and follow instructions above. If resistance to tool develops or cutting becomes difficult, dis-
continue 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.

Nibbler Attachment
The use of Stick Cutting Wax (264-5) or a cutting oil
will greatly improve the performance of the KETT
Nibbler. Use stick cutting wax on the underside of the
work piece for best results.

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 KL-2020 Electric Nibbler from power source before lubricating.
Once every three months, depending upon usage, remove the nibbler nead from the power unit by loosening the clamping screw (M133-36) and pull the
head off with a twisting motion. Lubricate the bearing surface of the eccentric bushing (41-24-1) with a good grade of bearing grease. Place nibbler head
back onto motor unit. Eccentric nut must be engaged with the link assembly as head is placed onto motor. Tighten clamping screw snugly to lock head
assembly in place.
Tools that have seen continuous use should also have the gear train lubricated periodically. 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 KL-2020 Electric Nibbler, so it will give you long and satisfactory
service.
