K-400 Drain Cleaning Machine
dles and controls. This aids inspection
and helps prevent the machine or control
from slipping from your grip. Clean and
maintain the machine per the mainte-
nance instructions.
4. Inspect the drain cleaning machine for
the following items:
• Proper assembly and completeness..
• Any broken, worn, missing, misaligned
or binding parts. Rotate the drum and
make sure that it turns freely.
• Make sure the foot switch is attached to
the drain cleaning machine. Do not oper -
ate the machine without the foot switch.
• Check the belt guard to insure that it is
securely fastened to the drain cleaner.
Do not operate without guard in place.
See Figure 1.
• Presence and readability of the warning
label (see Figure 8).
• Inspect the AUTOFEED. AUTOFEED
handle should move smoothly and freely
throughout range. Con firm that handle
returns to neutral position when re leased
(Figure 14). Confirm AUTO FEED guard
is securely in place.
• Any condition which may prevent safe
and normal operation.
If any problems are found, do not use
the drain cleaner until the problems
have been repaired.
5. Clean any debris from the cable and cut-
ting tools. Inspect cable for wear and dam-
age. Cable coupling plunger pin should
move freely and fully extend to securely re-
tain tools. Inspect cable for:
• Obvious flats worn into the outside of the
cable (ca ble is made from round wire
and the profile should be round).
• Multiple or excessively large kinks (slight
kinks up to 15 degrees can be straight-
ened)
• Uneven spacing between cable coils
indicating that the cable has been de-
formed by stretching, kinking, or run-
ning in reverse (REV)
• Excessive corrosion from storing wet or
exposure to drain chemicals.
All of these forms of wear and damage
weaken the cable and make cable twist-
ing, kinking or breaking more likely during
use. Replace worn and damaged cable
before using drain cleaner.
8
Make sure the cable is fully retracted with
no more than 6" (150mm) of cable outside
of the machine. This will prevent whip-
ping of the cable at start up.
6. 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 break-
age, and slow the drain cleaning process..
7 . Make sure that the FOR/OFF/REV switch
is set to the OFF position.
8. With dry hands, plug cord into properly
grounded outlet. Test the GFCI provided
in the electrical cord to insure that it is op-
erating correctly. When the test button is
pushed in, the indicator light should go off.
Reactivate by pushing the reset button in.
If the indicator light goes on, the GFCI is
functioning properly. If GFCI is not func-
tioning properly, unplug the cord and do
not use the drain cleaning machine until
the GFCI has been repaired.
9. 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-clock-
wise when viewed from the front of the
drum, and will match the drum direction
shown on the warning label (Figure 8).
Release the foot switch and let the drum
come to a complete stop. Place the FOR/ -
OFF/REV switch into the REV position,
and repeat above testing to confirm that
the drain cleaner operates properly in re-
verse. If the rotation is not correct, do
not use the machine until it has been re-
paired.
10. With the inspection complete, move the
FOR/OFF/REV switch into the OFF posi-
tion and, with dry hands, unplug the ma-
chine.
