CAUTION
• Be sure to mount the O-ring and the seal washers.
Also, be sure to apply Loctite to the mounting bolts.
Failure to apply Loctite will result in reduced dust-proof and water-proof
capabilities, causing water and powdery dust to enter.
• If wear is found in the O-ring, replace with new one.
• Once removed, the seal washers cannot be reused. Be sure to replace with
the new ones.
• Apply an appropriate amount of grease when mounting the O-ring.
