LIFEFORM ULTIMATE EXECUTIVE CHAIR MAINTENANCE AND TROUBLE SHOOTING TIPS
For upholstery cleaning instructions specific to the various types of leather, fabric or vinyl please refer to the “Examining Your Options” section of this reference guide.
Casters, bases, and arms can be wiped clean with a damp cloth. For extra shine, they can be polished with products specifically formulated for plastics, nylon and fiberglass.
Metal parts may be cleaned with a slightly damp cloth and then dried with a lint free towel.
Chair controls need lubricating once a year.
Cover the floor to protect it and lay the chair on the floor so the control is visible.
Wipe away any dust, dirt or old lubricant.
DO NOT USE SOLVENT LUBRICANTS as they attract dust and dirt which builds up in the joints, causing excessive wear and noise.
NEVER LUBRICATE THE CLUTCH PLATES as this will cause the clutch plates to slip and cause irreversible damage to the clutch.
Apply self-penetrating oil or a silicone, lithium, or motorcycle chain lubricant to the rivets attaching the inner and outer control structure and any other parts making contact EXCEPT THE CLUTCH PLATES.
Wipe away any excess lubricant and turn the chair upright.
TROUBLESHOOTING AND TIPS
Squeaks and Creaks
It may be that the plastic finger guard on your control has shifted in shipping and is now rubbing against the mechanism paddles. Remove the guard and reattach it to stop the clicking.
Lubricate the spring in the control with motorcycle chain lubricant or self-penetrating oil. DO NOT USE SOLVENT LUBRICANTS AND DO NOT LUBRICATE THE CLUTCH PLATES.Sometimes new chairs need time to break in, so wait a few days to see if the noises disappear.
Check/tighten bolts attaching the seat and back to the mechanism.
Gas lifts will squeak if left idle for extended periods of time. Lifting and lowering your chair, and rotating in your chair a few times will eliminate these squeaks.
Check casters and remove any carpet lint or grime. Check the bottom of the casters for flat spots. This can occur on chairs that are never moved. Replace casters if necessary.
Tighten hand wheels attaching arms to mechanism.
Using carpet casters on a plastic chair mat will make noise. This can be easily corrected by using soft wheel casters instead.
Tilt Lock and Back Angle Tension Adjustment
After years of use, the tilt lock and back angle adjustments may loosen and start to slip.
The paddles should have 1/4” to 1/2” of play. To test the play, lock the paddle and jiggle the end. If the paddle has no play, the clutch plates will slip, causing the paddle to snap out of place or fail to lock into place.
To ADD PLAY in the paddle (tighten the clutch), locate the nut securing the paddle bar on the opposite side of the paddle and use a 5/8”socket wrench to turn CLOCKWISE in 1/4” increments. This will increase the play in the lever and stop the clutch from slipping.
To REDUCE PLAY in the paddle (loosen the clutch), locate the nut securing the paddle bar on the opposite side of the paddle and use a 5/8” socket wrench to turn COUNTER-CLOCKWISE in 1/4” increments. This will decrease the play in the lever and loosen the clutch plates.
Tilt Tension Hand Wheels Replacement
Using a large #at head screw driver, simply remove the screw that holds the hand wheel in place, change out the hand wheel, and replace the screw.
