2. Setup and Assembly

The Lorell LLR42172 chair requires assembly. Ensure all components are present before beginning. It is recommended to assemble the chair on a soft, clean surface to prevent damage.

2.1 Components Checklist

• Chair Backrest
• Seat Cushion
• Armrests (2)
• Mechanism Plate
• Gas Lift Cylinder
• Five-Star Base
• Casters (5)
• Hardware Pack (screws, washers, Allen wrench)

2.2 Assembly Instructions

1. Attach Casters to Base: Insert each caster stem firmly into the holes at the end of each leg of the five-star base until it clicks into place.
2. Insert Gas Lift: Place the gas lift cylinder into the center hole of the assembled five-star base.
3. Attach Mechanism to Seat: Align the mechanism plate with the pre-drilled holes on the underside of the seat cushion. Secure with the provided screws and Allen wrench. Ensure the front of the mechanism faces the front of the seat.
4. Attach Armrests: Secure the armrests to the sides of the seat cushion using the provided screws. Do not overtighten initially to allow for minor adjustments.
5. Attach Backrest: Connect the backrest to the seat assembly, typically by sliding it into a bracket on the mechanism or securing it with screws through the armrests. Refer to the specific diagram in your included assembly guide for precise attachment points.
6. Connect Seat to Base: Carefully place the assembled seat and backrest onto the gas lift cylinder, ensuring the cylinder's top fits securely into the mechanism's central opening.
7. Final Tightening: Once all components are loosely assembled, tighten all screws securely.

3. Operating Instructions

Your Lorell LLR42172 chair offers several adjustment features to customize your seating experience for optimal comfort and support.

3.1 Seat Height Adjustment

• To Raise: While seated, lift the lever located on the right side of the chair (typically the front lever). Lift your weight slightly off the seat, and the seat will rise. Release the lever at the desired height.
• To Lower: While seated, lift the same lever. Remain seated, and the seat will lower. Release the lever at the desired height.

The seat height can be adjusted from approximately 18 inches to 21-3/4 inches.

3.2 Armrest Adjustment

• Height Adjustment: Locate the button or lever on the side of each armrest support. Press and hold this button/lever, then move the armrest up or down to your preferred height. Release the button/lever to lock it in place.
• Width Adjustment: Some armrests allow for width adjustment by loosening screws underneath the seat or at the armrest base, sliding the armrest in or out, and then re-tightening.
• Arm Pad Pivot: The arm pads can pivot. Gently rotate the arm pad to achieve the desired angle for forearm support.

3.3 Tilt Lock and Tension

• Tilt Lock: To lock the backrest in one of four positions, recline to the desired angle and then push the tilt lock lever (typically on the left side, or a rear lever on the right) inwards or downwards. To unlock, pull the lever outwards or upwards.
• Tilt Tension: The round knob located underneath the front of the seat controls the tilt tension. Turn clockwise to increase tension (making it harder to recline) or counter-clockwise to decrease tension (making it easier to recline). Adjust to match your body weight and preference.

3.4 Dual-Action Synchro Tilt

This feature allows the backrest to recline at a 2-to-1 ratio to the seat angle. This means the seat cushion remains relatively level to the floor while the back reclines, promoting an open hip angle. Engage this by unlocking the tilt mechanism and leaning back.

3.5 Seat Glide Mechanism

The seat glide mechanism allows you to adjust the seat depth. Locate the lever or button, typically on the left side of the seat. Activate it, then slide the seat forward or backward to adjust the depth from approximately 17 inches to 18-1/2 inches. Release the lever/button to lock the seat in position.

4. Maintenance

Regular maintenance helps preserve the appearance and functionality of your Lorell LLR42172 chair.

4.1 Cleaning

• Fabric Upholstery: For general cleaning, vacuum the fabric regularly to remove dust and loose debris. For spills, blot immediately with a clean, dry cloth. For stubborn stains, use a mild fabric cleaner according to the product instructions, testing on an inconspicuous area first.
• Plastic and Metal Parts: Wipe with a soft, damp cloth and a mild soap solution. Avoid abrasive cleaners or solvents, which can damage the finish.

4.2 Inspection

• Periodically check all screws and fasteners to ensure they are tight. Re-tighten as necessary to prevent wobbling or instability.
• Inspect casters for hair or debris accumulation. Clean them regularly to ensure smooth movement.
• Check the gas lift for proper function. If the chair does not hold its height, the gas lift may need replacement.

5. Troubleshooting

If you encounter issues with your chair, refer to the following common problems and solutions.

5.1 Chair Does Not Hold Height

• Possible Cause: Faulty gas lift cylinder.
• Solution: The gas lift cylinder may need to be replaced. Contact Lorell customer support for assistance.

5.2 Chair Squeaks or Wobbles

• Possible Cause: Loose fasteners or components.
• Solution: Inspect all screws and bolts, especially those connecting the seat, backrest, and armrests. Tighten any loose fasteners. Applying a small amount of silicone lubricant to moving parts (e.g., tilt mechanism) may also help.

5.3 Casters Do Not Roll Smoothly

• Possible Cause: Debris (hair, lint) caught in casters or damaged casters.
• Solution: Turn the chair over and carefully remove any debris from the caster wheels. If casters are damaged, they may need to be replaced.
