This document provides operating instructions and assembly details for the 7600R, 7602R, and 7605R Big Man's Chair, a robust seating solution designed for commercial usage. The chair is engineered with several adjustable features to enhance user comfort and support, along with a comprehensive warranty and maintenance guidelines.

The primary function of this chair is to provide comfortable and adjustable seating, particularly for individuals weighing up to 400 lbs, during a standard forty-hour work week. Its design incorporates multiple ergonomic adjustments to cater to individual preferences and ensure proper posture.

Function Description

The chair's core functionality revolves around its adjustable components, which allow users to customize their seating experience.

Pneumatic Seat Height Adjustment: This feature enables users to easily raise or lower the seat height. To raise the seat, pressure is removed from the seat, and lever (1) is lifted. To lower the seat, the user sits on the chair and lifts lever (1). It's noted that a slight lowering under body weight is normal, indicating a responsive pneumatic system. This adjustment is crucial for aligning the user's feet flat on the floor, promoting good circulation and reducing strain on the lower back.
3 Position 2-to-1 Tilt & Lock Adjustment: This deluxe control mechanism allows for a sophisticated tilting action where the back tilts two degrees for every one degree of seat tilt. The back can be locked into three distinct positions: fully back, mid, and upright. An anti-kickback feature is integrated, requiring pressure on the back to release, preventing sudden forward movement. To tilt or allow free float, lever (3) (located on the left side of the chair) is pushed back, and the user leans back. To lock the chair in a desired position, lever (3) is pushed forward. A distinct click will be heard when locked in the mid and fully back positions. To unlock, lever (3) is pushed back, and pressure is applied to the back. This tilt mechanism is essential for varying postures throughout the day, reducing static load on the spine and allowing for dynamic movement.
Arm Height Adjustment: The chair's arms can be adjusted in height to support the user's arms and shoulders. To adjust, button (4) is pushed in, allowing the arms to move freely up or down. Releasing button (4) locks the arms at the desired height. Users are cautioned not to completely loosen back tilt adjustment knob (2) during this process, as it could affect the back's stability. Proper arm height helps to alleviate tension in the neck and shoulders, especially during tasks requiring arm support.
Arm Width Adjustment: In addition to height, the armrests can also be adjusted for width. Pushing lever (5) down allows the arm to slide to the desired position. Pulling lever (5) up locks the arm into place. This feature ensures that the armrests can accommodate different body types and provide optimal support without forcing the user's arms inward or outward uncomfortably.

Usage Features

The chair is designed for straightforward assembly and operation, with clear instructions provided to ensure proper setup and safe use.

Assembly Process: The assembly instructions are broken down into five clear steps, starting with unpacking and verifying parts.
- Step 1: Involves inserting the five casters (2) into the base (1) until they snap into place, forming a stable foundation.
- Step 2: Focuses on attaching the arms (7L & 7R) to the seat cushion (5) using eight arm screws (8), emphasizing the need to fully tighten all screws with the provided Allen wrench (12).
- Step 3: Details attaching the seat plate (4) to the seat cushion (5) using four seat plate screws (9), ensuring the arrows on the seat plate face the front of the chair. Again, full tightening of screws is stressed.
- Step 4: Instructs on inserting the back support (11) into the rear of the seat plate (4) and securing it with three back support screws (10), with a final reminder to fully tighten all screws.
- Step 5: Concludes by inserting the pneumatic cylinder (3) into the base (1) and placing the assembled seat on top of the cylinder, applying downward pressure to secure it. The final instruction strongly emphasizes ensuring all screws are fully tightened before using the chair to prevent instability and potential hazards.
Safety Warnings: A comprehensive list of warnings is provided to ensure safe operation and prevent misuse. These include:
- Using the product for only one person at a time.
- Ensuring all bolts, screws, and knobs are securely tightened before use and checking them every three months or as needed.
- Avoiding overturning the back tilt knob when decreasing tension.
- Properly disposing of packing material, especially plastic covers, to prevent suffocation.
- Not using the chair as a stepladder.
- Using the chair only for its intended purpose.
- Using mild detergent only for cleaning.

Maintenance Features

The chair comes with a limited warranty and clear guidelines for maintenance and warranty claims, reflecting the manufacturer's commitment to product quality and customer support.

Limited Warranty: Pro-Line II chairs are warranted from the date of purchase against material and workmanship failures.
- Lifetime Warranty: Covers component parts including the pneumatic cylinder, control mechanism, base, and casters. This indicates a high level of confidence in the durability of these critical structural components.
- 3-Year Warranty: Applies to upholstery fabric and foam against wear and deterioration, acknowledging that these components are subject to more direct wear and tear.
- Leather Warranty: Specifically notes that leather is not warranted against routine scratching and scuffing, as minor blemishes are normal for leather.
- Warranty Limitations: The warranty is limited to the original purchaser for normal commercial usage, defined as a standard forty-hour work week by persons weighing 400 lbs or less. It explicitly excludes labor, freight, and damage resulting from misuse, abuse, negligence, alteration, accident, vandalism, rusting, acts of nature, or any other event beyond the control of Office Star Products. Cosmetic damage from normal use is also excluded.
- Extended Warranty for Heavy Usage: For usage exceeding 40 hours per week, a five-year warranty applies to all parts, while fabric and foam are warranted for one year. This provision acknowledges the increased stress on the chair under more intensive use.
- Exclusion of Liability: Liability for incidental or consequential damages is excluded, and the user assumes all risk of injury from product use.
Warranty Claim Process: To make a warranty claim, users are instructed to contact the Parts Department, providing the model number and a description of the problem to obtain return authorization. Office Star Products, at its option, will either supply compatible components of current manufacture or repair the customer's component. Customers must prepay freight for components returned to the factory, but return freight for components still under warranty will be paid by Office Star Products.
Customer Support for Parts: The document highlights the company's commitment to promptly remedying issues with damaged or missing parts. Customers can contact the Parts Department via e-mail (parts@officestar.net), fax (1-909-930-5629), or a toll-free number (1-800-950-7262) during specific business hours (Monday through Friday, 8:00 a.m. - 5:00 p.m. Pacific Time).
