"Maintenance
? No specific lubrication is necessary as the sealed bearings are pre-lubricated and bushings are self-lubricating. In case
of intensive usage, for example in adventure parks, or after use in water, you can use fluid oil (machine oil).
? Do not use WD 40 as it can dry out and damage the joints and bearings.
? Do not use a high pressure water sprayer. A high pressure spray can damage the joints and dry out the pulley by
removing oil from self-lubricating bushings, or cause water to enter the sealed bearings."
