EH FINAL ASSEMBLY
To ensure normal operation of the dock leveler, use
only aircraft hydraulic fluid designed to meet or exceed
military specification MIL-H-5606-G. It is recommended
that the following hydraulic fluids be used:
• ULTRA-VIS-HVI-15
• Aero Shell Fluid 4 or Fluid 41
• Mobile Aero HFA Mil-H5606A or Aero HF
• Texaco Aircraft Hydraulic Oil 15 or 5606
• Exxon Univis J13
• Castrol Brayco Micronic 756
These fluid brands can be mixed together. Use of
hydraulic fluids with equivalent specifications to those
listed here are acceptable.
Use of fluids that do not have equivalent specifications
to those in the preceding list will result in abnormal
operation of the dock leveler and voiding of warranty.

Weekly Maintenance
• Operate the dock leveler through the complete
operating cycle to maintain lubrication.
Note:
To thoroughly inspect the platform hinge area,
put the platform in the full below-dock position.
• Inspect the platform hinge and the lip hinge areas.
The hinge areas must be kept free of dirt and
debris. Build-up of foreign material in the hinge
areas will cause abnormal operation.
• Inspect warning decals and placards. Replace if
damaged or missing.
