Autofeed; Cleaning; Lubrication; Belt Removal/Installation - RIDGID K-400 Manual Del Usuario

coated with RIDGID Cable Rust Inhibitor. Once the cable
is clean and dry, pull the cable from the drum. While
manually feeding the cable back into the drum, wipe the
Cable Rust Inhibitor on the cable with a cloth.
Do not apply the Cable Rust Inhibitor to a rotating
cable. The cloth and your hand can become entangled in
the cable, and Cable Rust Inhibitor can be slung from ro-
tating cable.

AUTOFEED

After each use, hose out AUTOFEED assembly with
water and lubricate with lightweight machine oil.

Cleaning

The machine should be cleaned as needed with hot,
soapy water and/or disinfectants. Do not allow water to
enter motor or other electrical components. Make sure
unit is completely dry before plugging in and using.

Lubrication

Lubricate motor as per instructions on motor.
In general, the drain cleaner will not require lubrication.
If the drum is removed or changed, grease the bearings
with good general purpose grease.

Belt Removal/Installation

1. Remove belt guard by removing hold down screws lo-
cated next to motor. Do not operate 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 16.) Slide the
belt to the front of the machine near the front bearing
mount.
3. Remove the two screws and nuts holding the front
bearing mount in place. Pull the drum and front bear-
ing 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 limiter is set at the factory,
and in most cases will never need to be adjusted. If ex-
cessive belt slippage is experienced during use, this
procedure can be used to check and adjust the torque lim-
iter setting. Additionally, if the belt is changed, the torque
limiter will need to be checked and adjusted.
K-400 Drain Cleaning Machine
Do not adjust the torque limiter outside of the
NOTICE
specified range. Setting the torque limiter outside of the
specified range could result in damage to the machine and
cable.
1. Remove belt guard by removing hold down screws lo-
cated next to motor. Do not operate drain cleaner with
belt guard removed.
2. Check the gap between the torque limiter spring
coils near the middle of the spring. (See Figure 16.)
This can be measured with a set of feeler gauges.
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.
3. If torque limiter is outside of acceptable range, the
torque limiter must be adjusted.
4. Loosen screw located in the center of hex knob ap-
proximately 3 turns.
5. 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.
6. Repeat steps 2-5 until the spring coil gap is correct.
7. Tighten the hex knob screw.
8. Reverse procedure to replace the guard.

Installing Replacement Cable
To Remove Cable From Drum
1. Pull out excess cable from drum allowing access to
cable bracket.
2. Loosen screws on back of drum that fasten cable
clamps and back plate against back wall of drum.
