Maintenance
1. Lubricate machine with grease at grease fi ttings once a week if used
every day; once a month if used less.
2. Clean and lubricate Clutch Jaws with oil after each use.
3. Clean Cable Containers on 5/16” and 3/8” Cable Adapters after each
use by simply removing three screws.
4. Check brake drum on Cable Adapters periodically for possible
adjustment.
5. A clean machine works best.
See RIDGID/Kollmann Pipe and Drain Cleaning Equipment Catalogue for
descriptions and illustrations of all cables, tools and accessories.
Safety
The K-50 has a quick-acting “dead man” clutch for safety which allows the
cable to stop instantly when desired.
1. Wear operator’s glove. Never grasp a rotating cable with a cloth or
loose fi tting glove which can get caught in cable. Only use a Ridgid
leather glove with metal staples in the palm to handle cables.
2. Cables. Normally the cable is rotated clockwise at all times.
Counterclockwise rotation can result in cable damage and is used only
to back a tool out of an obstruction. Overstressing the cable can be
dangerous to the operator, as it may twist or kink. Do not use badly worn
cables or jaws.
3. Use a Guide Hose to prevent whipping and picking up debris by the
cable.
4. Use recommended equipment and accessories. Consult the
Catalogue for listings of such equipment. Use of improper equipment
may be hazardous.
5. Disconnect Power Cord before servicing and making any adjustments.
Operating instructions
Before operating the machine, the operator should become familiar with the
patented RIDGID/Kollmann T-Slot Speed Coupler method of joining cable
and tools. See Fig. 1.
Using 5/8” Sectional Cable
Position the machine one or two feet from the line opening and attach the
Guide Hose at the rear of the machine. Do this by lifting up the Lock Pin on
the Guide Hose Adapter, and sliding the Guide Hose Adapter onto the back
end of the machine until it locks in place. Plug the cord into any convenient
electrical outlet.
Insert the fi rst cable (and additional cables) into the front of the machine and
push it through the Guide Hose until a foot or so remains out the front of the
machine. Never couple more than one cable at a time!
The fi rst tool to use is the Bulb Auger, this being the best tool for going around
elbows. Snap it on, check coupling, make sure it is secure. Push cable by
hand into the line, holding the cable loosely in left hand. Put Switch into 1
(forward) (See Fig. 3) position and pull down on Clutch Handle with a defi nite
snap to rotate cable. A slow or gradual engaging of the Clutch Handle results
in a weak grip of the Clutch Jaws and causes excessive wear.
The clutch is instant acting and returning the Clutch Handle to its original
position frees the cable instantly. There is no overrun to loop or break the
cable- an important safety feature.
As soon as the excess cable has gone into the line, release the Clutch Handle
and pull six to ten inches of cable out of the machine. Repeat the engaging of
the clutch and this process, adding more cable sections as needed to reach
the obstruction. Remember, never couple more than one cable section at a
time! When the obstruction is reached, advance the cable inches at a time. At
this point the tool will do the work.
When the obstruction has been removed allowing passage of water, it is
recommended that a Straight Auger or Grease Cutter be used to ream out
the line ensuring a thorough job.
Use of REV (reverse)
The “2” (reverse) or counterclockwise running of the cable is only to free the
tools when they become snagged in an obstruction. Always let the motor
come to a complete stop, “0” OFF, before reversing and, as soon as the tools
are free, return to “1” (forward) position. Continuing to run in “2” (reverse)
risks breakage of the cable, since the cable is wound to have maximum
strength in clockwise or “1” (forward) position.
To bring the cable out, leave the switch in “1” (forward) position. Holding the
cable against the edge of the inlet, pull down on the Clutch Handle for several
seconds.
The cable will rapidly “thread” itself out of the line until a partial loop forms
in front of the machine. Release Clutch Handle and push excess cable back
through machine and repeat until all cable is out of the line.
Using 5/16” (A-17-A) or 3/8” (A-17-B) Cable Adapters
Attach the Cable Adapter to the K-50 in the following manner:
1. Pull ten inches of cable from Cable Adapter.
