Note:
•Once the grease tube has been opened, remove the nozzle from the tube, attach the cap securely and store the tube in a cool dark place.
•The grease should be used as quickly as possible.
•When using the grease again, remove any old grease from inside the nozzle first.
(Store the tube away carefully once the tube has been opened, otherwise the grease remaining inside the tube may deteriorate, and this may affect its lubricating performance.)
