SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE!
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
Work Area Safety
- Keep work area clean and well lit. Cluttered or 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 children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical Safety
- Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
- Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is
an increased risk of electric shock if your body is earthed or grounded.
- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
- Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
- When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
- If operating a power tool in a damp location is unavoidable, use a Ground Fault Circuit Interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.
- If operating a power tool in a damp location is unavoidable, use a Residual Current Device (RCD) protected supply. Use of a RCD reduces the risk of electric shock.
- It is recommended that the tool always be supplied via a Residual Current Device having a residual current of 30mA or less.
Personal Safety
- Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
- Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
- Prevent unintentional starting. Ensure the switch is in the OFF-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch ON invites accidents.
- Remove any adjusting key or wrench before turning the power tool ON. A
wrench or a key left attached to a rotating part of the power tool may result in personal injury.
- Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
- Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.

Description
The RIDGID ^® RP 251 Press Tool, when used with appropriate attachments, is designed to mechanically press fittings onto tubing to create a water-tight and permanent seal, such as for plumbing, heating, air conditioning, and refrigeration applications.
When the trigger/run switch on the press tool is depressed, an internal electric motor powers a hydraulic pump which sends fluid into the cylinder of the tool, moving the ram forward and applying force to the attachment, pressing the fitting. The press cycle takes approximately 4 seconds. Once the cycle begins to deform a fitting, it will automatically continue until completion, even if the trigger/run switch is released.
The tool includes a second operating mode ("Control Mode") that can be turned on using the RIDGID Link App. Control Mode allows the fitting to be engaged prior to pressing to allow confirmation of proper alignment of the attachment, fitting and tube.
The Tool Status Lights indicate things such as tool status, battery status, maintenance required, or improper temperature. A work light turns on when the trigger/run switch is depressed to power up the tool and helps illuminate the work area. The tool switches OFF after 120 seconds of inactivity.
The head can be rotated 360^ for better access in tight spaces. The tool is supplied with fabric loops that can be used with appropriate attachments such as shoulder straps or tie off lines.
The press tool include wireless technology to allow connection to smart phones and tablets. See “RIDGID Link App Connection (Wireless Communication)” section for details.
