Lubrication
The pack includes a packet of lithium grease.
It is recommended to apply it once a month, depending on use.
Clean with an absorbent tissue the remnants of lubricant
before applying. Only a small amount is needed to keep the
device in perfect condition.
NOTE: It's best to apply the grease with a toothpick while the
device is running, this way we make sure that the grease flows
inside the pusher's wall.
