2. Lubricate the chains monthly with 30W motor oil. Drip the oil onto the
chain plates and rollers. Let the oil soak in for a few minutes and then
remove any excess oil with a dry rag.
3. Remove the chains every three months to thoroughly clean and lubricate
them. Use a mild degreaser and a stiff brush to remove dirt and corrosion
from the chain. Read the instructions on the degreaser container before
using.
4. Clean each bearing plate and lubricate it with multipurpose grease every
three months. The plate is lubricated to reduce friction when the step
shaft bearings roll over the plate.

step hinges to lubricate the hinges and to prevent corrosion. Wipe off all
excess lubricant.
