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. Tools create sparks which may ignite the dust or fumes.

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

•Keep floors dry and free of slippery materials such as oil. Slippery floors invite accidents.

•Guard or barricade the area when work piece extends beyond machine. A guard or barricade that provides a minimum of three (3) feet clearance around the work piece will reduce the risk of entanglement.

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.

Grounding prong

Grounding prong

•Avoid body contact with grounded surfaces. There is an increased risk of electrical shock if your body is grounded.

•Don’t expose electrical tools to rain or wet conditions. Water entering a 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 and loss of power.

16	– 20	12 AWG	10 AWG	NOT RECOMMENDED

•Keep all electric connections dry and off the ground. Do not touch plugs or tool 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 in tools that have the switch ON invites accidents.

•Remove adjusting keys 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.

•Do not overreach. Keep proper footing and bal-

535 Manual Pipe and Bolt Threading Machine

ance 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

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

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

•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 for your tool. 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.

Specific Safety Information

WARNING

Read this operator’s manual carefully before using the 535 Threading Machine. Failure to understand and follow the contents of this manual may result in electrical shock, fire and/or serious personal injury.

Call the Ridge Tool Company, Technical Service Department at [phone] if you have any questions.

WARNING Foot Switch Safety

Using a threading machine without a foot switch increases the risk of serious injury. A foot switch provides better control by letting you shut off the motor by removing your foot. If clothing should become caught in the machine, it will continue to wind up, pulling you into the machine. Because the machine has high torque, the clothing itself can bind around your arm or other body parts with enough force to crush or break bones.

Machine Safety

•Threading Machine is made to thread and cut pipe or bolt and to power roll grooving equipment. Follow instructions on proper use of this machine. Do not use for other purposes such as drilling holes or turning winches. Other uses or modifying this power drive for other applications may increase the risk of serious injury.

•Secure machine to bench or stand. Support long heavy pipe with pipe supports. This practice will prevent tipping.

•Do not wear gloves or loose clothing when operating machine. Keep sleeves and jackets buttoned. Do not reach across the machine or pipe. Clothing can be caught by the pipe or machine resulting in entanglement and serious injury.

•Operate machine from side with REV/OFF/FOR switch. Eliminates need to reach over the machine.

•Do not use this machine if the foot switch is broken or missing. Foot switch is a safety device to prevent serious injury.

•Keep hands away from rotating pipe and fittings. Stop the machine before wiping pipe threads or screwing on fittings. Allow the machine to come to a complete stop before touching the pipe or machine chucks. This practice will prevent entanglement and serious injury.

•Do not use this machine to make or break fittings.

This practice is not an intended use of the machine and can result in serious injury.

•Tighten chuck handwheel and engage rear centering device on the pipe before turning on the machine. Prevents oscillation of the pipe.

•Keep covers in place. Do not operate the machine with covers removed. Exposure to moving parts may result in entanglement and serious injury.

NOTE! If a ring gage is not available, a fitting can be used. This fitting should be representative of those being used on the job. The pipe thread should be cut to obtain 2 or 3 turns hand tight engagement with fitting. If pipe thread is not proper diameter the index line should be moved in the direction of the OVER or UNDER size mark on size bar. (Refer to “Installing Dies In Die Heads”).

Priming Oil Pump

Current 535 Machines have a self-priming gerotor-type pump. Machines made prior to June 1, 1996 have a Model A vane-type pump that may require priming.

WARNING

All 535 Threading Machines made prior to June 1, 1996 should have a tube extension on the oil pump priming port, as well as a top cover access hole, so the pump can be primed without removing the top cover of the machine. This will prevent the operator from contacting the internal gearing of the machine which could result in serious injury.

If your older-style machine has a Model A Vane-Type pump and does not have a priming port, contact the Ridge Tool Company at 1-800-519-3456 or e-mail [e-mail] regarding a retrofit policy.

Ridge Tool Company

535 Manual Pipe and Bolt Threading Machine

To prime the Model A Pump, the following procedure should be followed:

1.Remove button plug located on cover.

2.Remove primer screw through opening with allen wrench.

3.Fill pump with oil.

4.Replace primer screw and button plug before starting machine or pump will drain itself immediately.

NOTE! If machine must be primed on a frequent basis, it is an indication the pump is in need of repair.
