7.8 Maintenance

LZ 70 FL and PL
All electric cylinders are provided with the required amount of lubricants ex-factory. The main-
tenance intervals are determined by the number of operating hours, loads and ambient influen-
ces. You should retract the push rod to 30 mm to lubricate the spindle and push rod. The electric
cylinder must be turned off after reaching the maintenance position (stroke "0 mm"). The threa-
ded plug for the spindle lubrication are removed by turning counter-clockwise, a piston driven
grease gun is inserted into the centre of the hole in the leading nut, and lubrica-
ted with two strokes.
The push rod is lubricated using the funnel-shaped grease nipple in the cover cap
with one stroke. Excess or extruded grease should be removed with a cloth.
The screw plug must be reinserted following maintenance work.
After 1,000 operating hours, the trapezoidal threaded spindle nut must be checked
for wear by testing the amount of thread play.
For versions with trapezoidal spindles Ø20x4, if axial play is
must be replaced.
For versions with trapezoidal spindles Ø20x8, if axial play is
must be replaced.
