● When lubricating, apply only 1-2 drops of oil (not grease), as extra oil will
drip on the rug and cause pollution as a result of over-lubrication.
● Depending on how often you use the chair, normally 1-2 times of
lubrication per month is fine. Proper lubrication can extend the life span of
a part in addition to prevent noise from accruing. Check if the bolts are
fastened while lubrication.
