MAINTENANCE
• Cylinders be replaced in the field. For cylinder replacement
and/or repairs, send the knee joint in for service.
• Knee joints must be stored upright. Storing cylinders or knee joints
on their side will cause the cylinder to draw in air. Air can be bled
from the system by engaging Swing Only mode and cycling the
cylinder until all of the air has been eliminated.
• Clean the extension stops regularly to prevent dirt buildup that may
compromise the cylinder release. Use a blunt instrument and be
careful not to scratch the contact areas.
Do Not disassemble the knee joint or attempt your own repairs. If a
problem should arise, send the knee joint in for service.
CLEANING
Wipe the knee with a soft cloth moistened with a small amount of
kerosene.
D use compressed air to clean the knee. Air will force pollutants
into the bearings which may cause malfunctions and early deterioration.
D use any solvents stronger than kerosene. Do not immerse the
whole knee or pour solvent over the knee, which would damage the
bearings and seals.
COSMETICS
D use talcum powder to eliminate noise in the cosmetic cover.
It reduces lubrication, which may lead to malfunctions and early
deterioration of mechanical parts. Use silicone spray instead.
