K-39/K-39B Drain Cleaning Machine
The autofeed will accumulate dirt, grease and debris
over time. Periodically remove the autofeed unit and
clean.
To remove autofeed:
1. Remove bolt on hand grip using allen key (Figure
13A).
Figure 13A
2. Push cable back so that it is past the autofeed.
3. Remove autofeed cartridge. (Figure 13B)
Figure 13B
NOTE! When replacing autofeed cartridge it will only fit
in one way.
Once a week a light grease should also be applied to the
autofeed roller bearing surface. This will extend the life of
the bearings and keep them free to operate properly.

cloth to remove rust and/or scale from inside of
sleeve.
4. Coat springs and inside sleeve with good quality
bearing grease and reassemble.

Batteries

1. Be alert for battery packs that are nearing their end of
life. Battery packs typically last from 250 to 500
charges. If you notice decreased tool performance or
significantly shorter running time between charges
then it is time to replace the battery pack. Failure to do
so can cause the tool to operate improperly or dam-
age the charger.
2. Long term battery storage should be in the dis-
charged state. Battery packs last longer and re-charge
better when they are stored discharged. Remember
to fully re-charge battery packs before using after
prolonged storage.

Battery Disposal

WARNING
tery or remove any component projecting from the
battery terminals. Fire or injury may result. Prior to dis-
posal, protect exposed terminals with heavy insulating
tape to prevent shorting.

If equipped with a nickel-cadmium battery, the battery
must be collected, recycled or disposed of in an envi-
ronmentally sound manner.

Nickel-metal Hydride Batteries
