The inside of the blade guides should be lightly lubricated on all three sides where the guides might contact the blade. The grease may be applied by using a long cotton tipped swab coated with the grease. There is also a groove on the right and left side of the blade guide area that must be filled with grease. See the illustration to identify the location of the grooves. Only one side is illustrated. The other side has a similar groove. The illustration shows a groove already filled with grease to help make it easy to see.Putting grease into these grooves is important. The following illustrations show how a small syringe loaded with grease is used to fill the grooves.
