General Safety Information

WARNING! Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious personal injury.

SAVE THESE INSTRUCTIONS!

Work Area Safety

•Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.

•Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.

•Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control.

Electrical Safety

•Grounded tools must be plugged into an outlet, properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user.

Cover of grounded outlet box

Grounding prong

•Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electrical shock if your body is grounded.

•Don’t expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of electrical shock.

•Do not abuse cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electrical shock.

•When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These

cords are rated for outdoor use and reduce the risk of electrical shock.

•Use only three-wire extension cords which have three-prong grounding plugs and three-pole receptacles which accept the tool’s plug. Use of other extension cords will not ground the tool and increase the risk of electrical shock.

•Use proper extension cords. (See chart.) Insufficient conductor size will cause excessive voltage drop, loss of power.

Minimum Wire Gauge for Extension Cord

Nameplate			Total Length (in feet)
Amps			Total Length (in feet)
Amps
		0 – 25		26 – 50	51 – 100
0	– 6	18 AWG		16 AWG	16 AWG
6	– 10	18 AWG		16 AWG	14 AWG
10	– 12	16 AWG		16 AWG	14 AWG
12	– 16	14 AWG		12 AWG	NOT RECOMMENDED

•Before using, test the Ground Fault Circuit Interrupter (GFCI) provided with the power cord to insure it is operating correctly. GFCI reduces the risk of electrical shock.

•Extension cords are not recommended unless they are plugged into a Ground Fault Circuit Interrupter (GFCI) found in circuit boxes or outlet receptacles.

The GFCI on the machine power cord will not prevent electrical shock from the extension cords.

•Keep all electric connections dry and off the ground. Do not touch plug with wet hands. Reduces the risk of electrical shock.

Personal Safety

•Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medications. A moment of inattention while operating power tools may result in serious personal injury.

•Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.

•Avoid accidental starting. Be sure switch is OFF before plugging in. Carrying tools with your finger on the switch or plugging tools in that have the switch ON invites accidents.

•Remove adjusting keys or switches before turning the tool ON. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.

K-40 Drain Cleaner

•Do not over-reach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.

•Use safety equipment. Always wear eye protection.

Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

Tool Use and Care

•Use clamp or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.

•Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.

•Do not use tool if switch does not turn it ON or OFF. Any tool that cannot be controlled with the switch is dangerous and must be repaired.

•Disconnect plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce risk of starting tool accidentally.

•Store idle tools out of the reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.

•Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edges are less likely to bind and are easier to control.

•Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.

•Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool may become hazardous when used on another tool.

•Keep handles dry and clean; free from oil and grease. Allows for better control of the tool.

Service

•Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified repair personnel could result in injury.

•When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance Section of this manual. Use of unauthorized parts or failure to follow maintenance instructions may create a risk of electrical shock or injury.

Operating Instructions

WARNING

Never grasp a rotating cable with a rag or loose fitting cloth glove that may become wrapped around the cable causing serious injury.

Always wear eye protection to protect your eyes against dirt and other foreign objects. Wear rubber soled, non-slip shoes.

Be very careful when cleaning drains where chemical compounds have been used. Avoid direct contact of the skin and especially the eyes and facial area as serious burns can result. Rinse hands thoroughly after contact with chemical compounds.

Cleaning Drain Line Using Machine

Without Autofeed

1.Place the FORWARD/REVERSE switch in the FORWARD position.

CAUTION Power unit must be completely stopped before moving FORWARD/REVERSE switch. REVERSE position is used only when removing cable from an obstruction or retrieving the cable after the drain is cleared.

2.Pull out enough cable by hand to insert into the drain opening and hand-feed the cable into the drain until it stops feeding easily (Figure 15).

3.Turn the machine on by depressing the foot pedal.

4.Continue hand-feeding the cable slowly until the drain is opened or blockage is encountered. Keep your cable hand close to the drain opening to keep control of the cable and help prevent cable flip-over.

Figure 15 – Push cable down drain line keeping your control hand close to the drain opening

WARNING Keep your other hand on the extended cable between K-40 and your cable hand to steady the exposed cable and maintain cable control.

5.When you reach the blockage, work the cable back and forth to clear the obstruction. At this point,

progress depends on the type of tool being used and nature of the blockage. Advance cable slowly.

6.If cable/blade gets hung up in obstruction, release the foot pedal and let motor come to a complete stop before reversing.

7.Place FORWARD/REVERSE lever in REVERSE position.

8.Press foot pedal only until cable/blade is free of obstruction. Release foot pedal immediately.

NOTE! Only run machine in REVERSE if relieving cable from a blockage or retrieving the cable with the Autofeed.

9.As soon as cable/blade is free and motor has stopped, return FORWARD/REVERSE lever to FORWARD position.

10.Continue feeding cable by following Steps 4 through 9 until through obstruction.

11.The speedbump cable end indicator, located approximately 84″ from the back end of the cable, is a 1/2″ expanded bump in the cable to warn the operator

there is only 6′ of usable cable left. (Figure 23)

12.To withdraw cable from line with machine running, leave FORWARD/REVERSE lever in FORWARD position and slowly pull cable from drain.

13.As excess cable is retrieved from line, hand-feed cable back into K-40 Drum.

14.Turn machine OFF just prior to cable or tool emerging from drain opening. Retrieve by hand as cable or tool may contain debris and splash work area.

Cleaning Drain Line Using Guide Hose

With Autofeed

1.Place FORWARD/REVERSE switch into FORWARD position. Keep autofeed close to drain opening, approximately 2″ – 6″ (Figure 16).

2.Hand feed approximately one to two feet of cable into the drain opening.

3.Turn machine ON by depressing foot pedal and be sure entire cable is spinning before continuing.

4.Depress the autofeed’s feed actuator lever and feed cable into drain.

NOTE! Know how long your run of pipe is prior to cleaning. Running too much cable can damage your equipment and the drain.

10	Ridge Tool Company

Figure 16

5.Feed cable into drain until obstruction is encountered or cable begins to bind up.

6.If cable begins to bind up, release feed actuator lever and pull cable back slightly by hand. Refeed cable into blockage again. If advancing the cable with the autofeed is difficult, discontinue using it and advance the cable by hand until the line clears.

7.Once drain is open and flowing, continue feeding additional cable with autofeed to clean rest of drain.

8.The speedbump cable end indicator, located ap-

proximately 84″ from the back end of the cable, is a 1/2″ expanded bump that will not pass through the autofeed and warns the operator it is time to retrieve the cable. (Figure 23)

9.To retrieve cable, stop machine completely.

10.Switch the FOR/REV switch to REV.

11.Turn machine ON and depress the feed actuator lever. It will automatically retrieve the cable from the drain.

12.Turn machine OFF just prior to cable or tool emerging from drain opening. Retrieve by hand as cable or tool may contain debris and splash work area.

HINT! If your cable tool/retriever bulb has hooked onto a solid blockage such as a rag or ball or hair, it may be wise to pull the cable out of the drain by hand. Reversing the cable to retrieve it may cause the blockage to unscrew off the cable.

NOTE! The only adjustment on the autofeed is the round top adjustment screw under the feed actuator lever. Its purpose is to adjust the distance the feed actuator lever has to be depressed to engage the different size cables. Turn knob clockwise to accommodate the larger 3/8″ cable and turn knob

counter clockwise to accommodate the 5/16″ cable. No adjustment is necessary direct from the factory.

Special Procedures

Loading Cable Into Drum

Your K-40/K-40B is supplied with an inner drum that fits snugly inside a two-piece drum that allows easy changeout of cable. To access the inner drum feature:

1.On units supplied with mounting bracket, remove one mounting bracket bolt and loosen the remaining one. Swing mounting bracket to OPEN position (Figure 17).

Figure 17 – Mounting Bracket Swung OPEN For Drum

Access

2.Loosen the four screws that hold the drum front to the drum back. Loosen each screw about 3 full turns

(Figure 18).

3.Separate the drum front from the drum back by twisting apart (Figure 19).

Figure 19 – Twist Drum Apart

4.Lift the inner drum, with cable, out of its cradled fit.

5.Fit the new inner drum into the drum back and draw about a foot of cable out of the inner drum (Figure 20).

Figure 20 – When loading cable into an inner drum, wind the cable in CLOCKWISE.

6.Pass the exposed cable head through the drum front assembly, align the drum front with the drum back, and rotate drum front to lock into position. Tighten the screws.

Torque Arm

The K-40/K-40B is supplied with a torque arm inside the inner drum (Figure 21) and attached to the back end of the cable (Figure 22).

The torque arm retains the cable inside the inner drum of the K-40/K-40B and greatly enhances the performance of the machine. It is adjustable to different sizes of cable ranging from 1/4″ through 3/8″.

Cable End Indicator

The C-13-IC SB Cable has a “speedbump” at the back end of the cable (Figure 23). This bump in the cable will warn you to stop feeding cable out of the drum. The “speedbump” is most effective on K-40 units with the autofeed accessory. The bump will not pass through the autofeed during operation of the machine. To pass the bump through the autofeed, lift the actuator handle. Continuing to feed the cable past the speedbump may result in the cable coming out of the inner drum requiring you to reload the cable.

Maintenance Instructions

WARNING

Make sure machine is unplugged from power source before making any adjustment.

1.Cables should be thoroughly flushed with water after each use to prevent damaging effects of drain cleaning compounds. RIDGID Cable Rust Inhibitor should be applied prior to storage.

When not in use, store cables indoors to prevent deterioration by the elements.

NOTE! Cables should be replaced when they become severely corroded or worn. A worn cable can be identified when outside coils of cables become flat.

2.Use a clean cloth to wipe the unit off. Oil, grease and other substances may cause deterioration. Certain cleaning agents and solvents damage plastic parts. Some of these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia. Avoiding use of these and other types of cleaning agents minimizes the probability of damage.

3.It is a good idea to regularly drain the inner drums of any captured liquid. Simply hold the machine nose down and drain excess liquid each time the machine is used.

NOTE! Remove the Guide Hose accessory for ease of draining.

4.Store the unit where it is cool and dry. Avoid those areas where the temperature will drop to 0°F or exceed +120°F.

Autofeed

A drop of grease to the following areas once a month will extend the life of the Autofeed unit and keep it well maintained.

a.Top of Large Top Adjustment Screw

b.Threads on Bottom of Top Adjustment Screw

c.Outside Diameter of Top Roller Holder housing

There are no grease fittings to worry about, however, the autofeed will accumulate dirt, grease and debris over time. It is a good idea to periodically remove the autofeed unit and clean with cleaning solvent and a firm brush.

It is also a good idea to apply a light grease once a week, to the autofeed roller bearing surface. This will extend the life of the bearings and keep them free to operate properly.
