9.6.2 Hydraulic Cylinders
Every 10 operating hours or daily, and every time before starting up again after a
longer period of rest, clean all cylinders and check them for tightness.
Risk of damaging the piston rod!
Do not clean cylinder piston rods with a water jet, sharp tool, caustic lye
or an abrasive.
Serious accident hazard!
Immediately repair or replace cylinders that are not tight.
Every 50 operating hours or once a week grease the cylinder lugs (holes for pins).
On cylinders that are kept extended during rest:
Risk of corrosion damage in corrosion-supporting environments!
The tasks specified below must be carried out without fail.
Once or twice a week, rub down piston rods with hydraulic oil, or retract and extend
the rods repeatedly.
Before a longer standstill, preserve piston rods with acid free grease.
