Maintenance
Bolts
- Check bolts regularly for correct tightness. Bolts should be tightened
Firmly so that they do not slop around in bolt holes, but should not be
over-tightened to cause restrictive movement of parts. Worn bolts
should be replaced immediately.
Cylinder
- Keep top and lower plunger rods clean of dirt or other foreign
substances to assure smooth operation of cylinder.
- Make sure all threaded connections are tight to assure smooth
operation of cylinder.
- Replace seals, wipers, and O-rings if cylinder is leaking oil.
- Lubricate top plunger rod where rod enters top reservoir with an
aerosol type lubricant.
- It is recommended when head gate is not in use to fully open doors.
This will place the bottom plunger into the cylinder protecting it
from the elements.
- Change to oil in the cylinder every 4 years or as needed.
- Any cylinder malfunction should be immediately reported to your
dealer or Sioux Steel.
