dles and controls. This helps prevent the machine or
control from slipping from your grip.

4. Make sure the foot switch is attached to the drain
cleaning machine. Do not operate the machine with-
out the foot switch.
5. Make sure the machine is properly assembled. Inspect
the drain cleaning machine for any broken, worn,
missing, mis-aligned or binding parts or any other
condition which may prevent safe and normal opera-
tion. Make sure that handles move smoothly between
positions and lock in place, and that the bumpers at
the bottom of the handle are present and firmly at-
tached. Rotate the drum and make sure that it turns
freely without binding. If any problems are found, do
not use machine until problems have been repaired.
6. Check that the warning label is present, firmly at-
tached and readable. Do not operate the drain clean ing
machine without the warning label. See Figure 7.

7. Check the belt guard to insure that it is securely fas-
tened to the drain cleaner. Do not operate without
guard in place. See Figure 1.
8. Clean any debris from the cable and tools. Inspect ca-
bles for wear and damage. Inspect for
• Wear – wear can be identified by looking for flats on
the outside of the cable. Cables are made from
K-400 Drain Cleaning Machine
round wire, and the outside of the cable should be
rounded like the wire profile. If you can see an ob-
vious flat on the outside of the cable, it is worn and
should be replaced.
• Cable kinks – If the cable is not perfectly straight but
is slightly "wavy", that is acceptable. Kinked cables
have a well-defined bend, and may have gaps be-
tween the coils of the cable. Slight kinks (up to 15°)
can be straightened, but all kinks weaken the cable
and can cause cable failure during use. Cables
with multiple or excessively large kinks should be re-
placed.
• Space between cable coils – space between the
cable coils indicates that the cable has been de -
formed. This can be caused by kinking, stretching
(mechanically pulling the cable) or running the cable
in REVERSE (REV). Cables with space between
the coils should be replaced.
• Excessive corrosion – this can be caused by storing
the cable wet or using the cable in corrosive chem-
icals used in chemical clog removers. Corrosion
weakens the cable and can make it brittle. Ex -
cessively corroded cable should be replaced.
All of these forms of wear and damage weaken the
cable and make cable twisting, kinking or breaking
more likely during use. Make sure the cable is fully re-
tracted with no more than 2" of cable outside of the
machine. This will prevent whipping of the cable at
start up.
9. Inspect the tools for wear and damage. If necessary,
replace prior to using the drain cleaning machine. Dull
or damaged cutting tools can lead to binding, cable
breakage, and slow the drain cleaning process.
10. Make sure that the FOR/OFF/REV switch is set to the
OFF position.
11. With dry hands, plug cord into properly grounded
outlet. Test the GFCI provided in the electrical cord to
insure that it is operating correctly. When the test
button is pushed in, the indicator light should go off.
Reactivate by pushing the reset button in. If the indi-
cator light goes on, the GFCI is functioning properly.
If GFCI is not functioning properly, unplug the cord and
do not use the drain cleaning machine until the GFCI
has been repaired.
12. Move the FOR/OFF/REV switch into the FOR position.
Press the foot switch and note the direction of rotation
of the drum. If the foot switch does not control the ma-
chine operation, do not use the machine until the
foot switch has been repaired. The drum should rotate
counter-clockwise when viewed from the front of the
drum, and will match the drum direction shown on the
