The provided documents describe the Rapid-Torc RT-3 hydraulic torque wrench, its torque chart, and a quick setup guide.

The RT-3 is a hydraulic torque wrench designed for precise and controlled tightening of fasteners. Its primary function is to apply a specific amount of rotational force (torque) to a bolt or nut, ensuring secure and accurate fastening in various industrial applications. The device operates by converting hydraulic pressure from a pump into mechanical torque.

Important Technical Specifications:

The core technical specification provided is the correlation between pump gauge pressure (in PSI or BAR) and the resulting torque output (in FT.LB. or NM). This relationship is detailed in the "RT-3 TORQUE CHART."

Pressure Range and Corresponding Torque (Foot-Pounds):
- Minimum: 1500 PSI yields 485 FT.LB.
- Maximum: 10000 PSI yields 3230 FT.LB.
- The chart provides incremental values, for example:
  - 2000 PSI = 646 FT.LB.
  - 4000 PSI = 1292 FT.LB.
  - 6000 PSI = 1938 FT.LB.
  - 8000 PSI = 2584 FT.LB.
Pressure Range and Corresponding Torque (Newton-Meters):
- Minimum: 104 BAR yields 657 NM
- Maximum: 690 BAR yields 4379 NM
- The chart provides incremental values, for example:
  - 138 BAR = 876 NM
  - 276 BAR = 1752 NM
  - 414 BAR = 2628 NM
  - 552 BAR = 3503 NM

These torque values are specifically applicable when using a calibrated RT-3 hydraulic torque wrench powered by a 10,000 PSI pump fitted with a calibrated Class 1 gauge. This highlights the importance of using compatible and calibrated equipment for accurate torque application.

Usage Features:

The "QUICK SETUP GUIDE" outlines four basic steps for operating the RT-3, emphasizing safety and proper procedure.

Wear PPE (Personal Protective Equipment): Before operation, users are instructed to wear essential PPE, including eyeglasses and steel-toe shoes. This underscores the importance of safety in industrial environments where such tools are typically used.
Connect Hoses: Users must ensure that the hydraulic hoses are free of defects. The couplers, located on the pump, should be securely connected to the tool. The guide advises placing the tool on a flat surface during this step, suggesting a stable setup is crucial.
Cycle Your Tool: This step describes the initial operation to prepare the tool.
- Turn the pump on.
- Press and hold the "ON" button on the remote control until the tool clicks.
- Release the button and wait for the tool to click again.
- Repeat this cycle to ensure there are no leaks in the system. This cycling process likely primes the hydraulic system and verifies its integrity before applying torque.
Set Pressure: This is the critical step for achieving the desired torque.
- Users must refer to the "torque conversion chart" (the "RT-3 TORQUE CHART") to identify the PSI or BAR setting corresponding to the required torque.
- With the remote's "ON" button pressed, the pressure regulator on the pump is slowly turned clockwise until the desired pressure is reached. This allows for precise control over the torque output.

The guide also mentions that a brief overview video on how to use the document is available by scanning a QR code or visiting rapidtorc.com/torque_setup, indicating a commitment to user support and ease of understanding.

Maintenance Features:

While the provided documents do not explicitly detail maintenance features, several points can be inferred:

Calibration: The note "The above torque values are only applicable when using a calibrated RT-3 hydraulic torque wrench powered by a 10,000 psi pump fitted with a calibrated class 1 gauge" strongly implies that regular calibration of both the torque wrench and the pump's gauge is essential for maintaining accuracy and reliable performance. This is a critical aspect of preventative maintenance for precision tools.
Hose Inspection: The instruction to "Make sure the hoses are free of any defects" before connecting them suggests that routine inspection of the hydraulic hoses for wear, damage, or leaks is a necessary part of pre-operation checks, contributing to the longevity and safe operation of the system.
Leak Detection: The "Cycle Your Tool" step explicitly includes "Ensure there is no leak" as part of the process. This indicates that checking for leaks is a standard operational procedure, which also serves as a form of immediate maintenance check to prevent system failures or fluid loss.
User Manual and Safety Instruction Booklet: The "QUICK SETUP GUIDE" advises users to "Please read the included user manual and safety instruction booklet for additional guidelines." This suggests that more comprehensive information regarding maintenance schedules, troubleshooting, and detailed safety protocols would be found in these accompanying documents.

In summary, the RT-3 hydraulic torque wrench is a precision tool designed for controlled fastening, with its operation heavily reliant on accurate hydraulic pressure settings. Its usage is guided by clear, step-by-step instructions that prioritize safety and accuracy, while implied maintenance practices focus on calibration, inspection, and leak detection to ensure consistent performance.
