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 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 KM-440 Electric Shear, so it will give you long and satisfactory
service.
