K-400 Drain Cleaning Machine

Cables

Cables should be thoroughly flushed with water
after every use to prevent damaging effects of
sediment and drain cleaning compounds. Flush
cable with water and drain debris from drum by
tipping machine forward after every use to re-
move sediment, etc. which can corrode cable.
Cable connector plunger pin can be lubri-
cated with light machine oil.

AUTOFEED Cable Feed

After each use, hose out AUTOFEED cable
feed assem bly with water and lubricate with
lightweight machine oil.

Lubrication

In general, the drain cleaner will not require lu-
brication. If the drum is removed or changed,
grease the bearings with good general pur-
pose grease.

Front Guide Hose

After use, flush the guide hose with water and
drain.

Belt Removal/Installation

1. Loosen belt guard screws (near motor)
and slide guard off screws. Do not oper-
ate drain cleaner with belt guard removed.
2. Hold the belt tensioner to the side and
remove the belt from the drum and pulley.
(See Figure 17 .) Slide the belt to the front
of the machine near the front bearing
mount.
3. Remove the bolts and nuts holding the
front bearing mount and AUTOFEED
cable feed (see Figure 5) in place. Pull the
drum and front bearing mount forward
enough to slide the belt off the machine,
between the front bearing mount and the
frame.
4. Reverse procedure to replace belt. If
changing belt, adjust torque limiter as
described below.

Torque Limiter Adjustment

The K-400 Drain Cleaner is equipped with a
torque limiter to help prevent cable damage
from flip over in the drum.
The torque limiter causes the belt to slip when
the torque exceeds a set value. The torque lim-
iter is set at the factory, and in most cases will
never need to be adjusted. If excessive belt
16
slippage is experienced during use, this proce-
dure can be used to check and adjust the
torque limiter setting. Additionally, if the belt is
changed, the torque limiter will need to be
checked and adjusted.
Do not adjust the torque limiter out-
NOTI E
side of the specified range. Setting the torque
limiter outside of the specified range could
result in damage to the machine and cable.
1. Loosen belt guard screws (near motor)
and slide guard off screws.
2. Check the gap between the torque limiter
spring coils near the middle of the spring.
(See Figure 17 .) This can be measured
with a set of feeler gauges.

3. The torque limiter is properly set if the
gap is 0.048" (1.22 mm) to 0.060" (1.52
mm), about the thickness of a U.S. dime.
If the gap is within this range, the torque
limiter is properly set and no adjustment is
necessary.
4. If torque limiter is outside of acceptable
range, the torque limiter must be adjusted.
5. Loosen screw located in the center of
hex knob approximately 3 turns.
6. Pull the hex knob out slightly. If the gap
needs to be increased, rotate the knob
clockwise to the next flat of the hex knob.
If the gap needs to be decreased, rotate
counter-clockwise to the next flat of the
hex knob.
7 . Repeat steps 2-5 until the spring coil gap
is correct.
8. Tighten the hex knob screw.
9. Replace the guard. Do not operate drain
cleaner with belt guard removed.
