After sealing in the grease, move the nut about three times the full length of the nut to distribute

Cautions When Sealing
Caution
"A matter which, if mishandled, could result in
physical injury or in only material damage."
(1) Grease will leak from the seal unless the shaft is rotated while sealing, preventing sealing the
specified amount in the nut.
(2) Wipe off any leaked grease, and redo grease sealing, following the sealing directions. Contact
THK for the grease sealing amount.
