SX4400 Swinging Bucket Rotor
Care and Maintenance

Cleaning

Wash rotor components immediately if salts or other corrosive materials are used or if spillage has
occurred. Do not allow corrosive materials to dry on the rotor.
Under normal use, wash the rotor frequently (at least weekly) to prevent buildup of residues.
NOTE
Do not wash the rotor components in a dishwasher. Do not soak the rotor in detergent solution for long
periods, such as overnight.
Rotor Components
1
Wash the rotor yoke and tie-down screw in a mild detergent, such as Solution 555 (339555), that
won't damage the rotor.
• The Rotor Cleaning Kit (339558) contains two plastic-coated brushes and two quarts of
Solution 555 for use with rotors and accessories.
• Dilute the detergent 10 to 1 with water.
2
Thoroughly rinse the cleaned rotor components with distilled water.
3
Air-dry the rotor components upside down.
• Do not use acetone to dry the rotor.
4
Lubricate the rotor pins with Spinkote (306812).
Before reinstalling the rotor yoke, lightly lubricate the drive hole with Spinkote (306812) to prevent
the rotor from sticking, as follows:
1
Apply the lubricant onto a swab.
2
Draw the coated swab through a paper towel to remove excess lubricant.
3
Lightly coat the inside of the drive hole with the lubricant remaining on the swab.
Buckets
