This manual provides detailed instructions for replacing the control mechanism of a Steelcase Leap V2 chair, specifically for models manufactured after March 20, 2006. The instructions are presented as a removal guide, with the understanding that installation involves reversing the steps. This approach ensures a comprehensive understanding of the chair's assembly and disassembly process, which is crucial for proper maintenance and repair.
The Steelcase Leap V2 chair is designed with user comfort and adjustability in mind, featuring a sophisticated control system that allows for various ergonomic adjustments. The replacement process outlined in this manual focuses on the core control unit, which governs many of these adjustments.
The primary function of the Steelcase Leap V2 chair's control mechanism is to enable a wide range of ergonomic adjustments, allowing users to customize the chair to their individual preferences and body types. These adjustments are critical for maintaining proper posture, reducing strain, and enhancing comfort during prolonged periods of sitting. The control unit integrates several key functionalities:
Seat Slide Lever: This lever allows the user to adjust the depth of the seat. By sliding the seat forward or backward, users can ensure proper thigh support and maintain a comfortable distance from the backrest. This feature is particularly important for individuals of varying leg lengths, preventing pressure points behind the knees and promoting healthy circulation. The manual details how to operate this lever in conjunction with a quick release tab to slide the seat forward for removal.
Quick Release Tab: Located on the left-hand side of the chair, this tab works in tandem with the seat slide lever to facilitate the forward movement of the seat. Lifting this tab disengages a locking mechanism, allowing the seat to slide freely. This design ensures that the seat remains securely in place during normal use but can be easily adjusted or removed for maintenance.
Arm Adjustments: The chair's arms are designed to be adjustable, providing support for the user's arms and shoulders. The manual describes a process for removing the outer pod cover and arm, which varies slightly depending on the chair's color (black/midnight or platinum). This suggests a modular design for the armrests, allowing for easier replacement or repair of individual components. The arm adjustment mechanism likely includes height, depth, and pivot options, though the manual focuses on the removal process. The trigger button mentioned in the arm removal step indicates a spring-loaded or locking mechanism that must be disengaged to free the arm from its insert.
Control Cover and Cowling: These components serve both aesthetic and protective functions. The control cover encases the internal control mechanisms, protecting them from dust, debris, and accidental damage, while also providing a clean, finished look. The cowling, typically located at the rear, serves a similar purpose, covering the lower back portion of the chair's frame. Their removal is a prerequisite for accessing the underlying control unit. The warning about the chair back being free to move after the control cover screws are removed highlights the structural integration of these components and the importance of careful handling during disassembly.
Back Frame and Seat Carrier: These are fundamental structural components of the chair. The back frame supports the backrest, while the seat carrier provides the base for the seat cushion and integrates with the control mechanism. The ability to compress the back frame inward off arm rivets and remove both the back frame and seat carrier indicates a design that allows for significant disassembly, facilitating access to the core components for repair or replacement.
Pneumatic Cylinder: This is a crucial component responsible for the chair's height adjustment. The pneumatic cylinder allows users to raise or lower the seat to achieve an optimal ergonomic height relative to their desk or workstation. The manual provides specific instructions for removing the cylinder using a specialized tool, emphasizing the need for firm hits to dislodge it. This suggests that the cylinder is press-fit into the chair control housing, ensuring a secure connection during use. The recommendation to apply WD-40 if the cylinder is stuck indicates a common issue with such components and offers a practical solution for stubborn cases.
The Steelcase Leap V2 chair is renowned for its intuitive and extensive adjustability, making it suitable for a wide range of users and work environments. While this manual focuses on the replacement of the control mechanism, the underlying design principles highlight several key usage features:
Ergonomic Design: The chair's design prioritizes ergonomic support, aiming to adapt to the user's natural movements and postures. The various adjustment points, including seat depth, arm height, and back support, allow users to fine-tune the chair to their specific needs, promoting healthy spinal alignment and reducing musculoskeletal discomfort.
Dynamic Support: The Leap V2 is known for its "LiveBack" technology, which allows the backrest to flex and change shape to mimic the natural movement of the spine. While not directly addressed in the control replacement steps, the integrity of the control mechanism is essential for the proper functioning of this dynamic support system.
Ease of Adjustment: The inclusion of levers and tabs for adjustments, such as the seat slide lever and quick release tab, suggests that the chair is designed for easy and intuitive operation. Users can quickly and effortlessly modify their seating position without needing to exert excessive force or consult complex instructions.
Durability and Maintainability: The detailed disassembly instructions, including the removal of covers, arms, and structural components, indicate that the chair is designed for long-term use and maintainability. The ability to replace individual control components, rather than the entire chair, extends its lifespan and reduces waste. The specific tools and techniques described for pneumatic cylinder removal further underscore this commitment to serviceability.
Customization: The different methods for arm removal based on chair color (black/midnight vs. platinum) suggest that there may be slight variations in the chair's construction or aesthetic options, allowing for a degree of customization in its appearance.
The manual itself serves as a critical maintenance feature, providing the necessary guidance for repairing and servicing the Steelcase Leap V2 chair. Key maintenance aspects highlighted include:
Component-Level Replacement: The instructions clearly demonstrate that the control mechanism is designed for component-level replacement. Instead of requiring the disposal of the entire chair when a control unit fails, specific parts can be removed and replaced, making repairs more economical and environmentally friendly.
Step-by-Step Disassembly: The detailed, numbered steps with accompanying illustrations make the disassembly process clear and manageable, even for individuals who may not be professional technicians. This empowers users or facility managers to perform basic repairs, reducing downtime and service costs.
Specialized Tooling: The mention of a "pneumatic cylinder removal tool" (Service part 4620551SR / Part number 879100100) indicates that some maintenance tasks may require specialized equipment. This ensures that repairs are performed correctly and safely, preventing damage to the chair or injury to the person performing the repair. The availability of such tools suggests a well-supported product line with a focus on long-term serviceability.
Troubleshooting Tips: The advice to apply WD-40 if the pneumatic cylinder does not separate from the control is a practical troubleshooting tip. It addresses a common issue encountered during cylinder removal and provides a simple, effective solution, demonstrating an understanding of real-world maintenance challenges.
Safety Precautions: The warning to "Hold chair back firmly to avoid possible injury" after removing the control cover screws highlights the importance of safety during maintenance. This indicates that certain components may become unstable during disassembly, and proper handling is crucial to prevent accidents.
Reference to Additional Instructions: The instruction to "Refer, also, to Pneumatic Cylinder Adjustment/Replacement Instructions (939546212)" points to a modular documentation system. This ensures that users have access to comprehensive information for specific repair tasks, preventing the manual from becoming overly long while still providing all necessary details.
In summary, the Steelcase Leap V2 chair is a sophisticated piece of office furniture designed for ergonomic excellence and long-term durability. Its control mechanism, while complex, is engineered for maintainability, allowing for component-level replacement and repair. The detailed instructions provided in this manual are essential for ensuring the chair's continued functionality and extending its lifespan, reflecting Steelcase's commitment to quality and user support.
