MAINTENANCE
To ensure normal operation of the RRH 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-H5606 G or Aero HF
• Texaco AiRRHaft Hydraulic Oil 15 or 5606
• Exxon Univis J13
These fluid brands can be mixed together. Mixing
with fluids that do not meet or exceed MIL-H-5606-G
may damage the equipment and WILL void warranty.
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 following list will result
in abnormal operation of the dock leveler and
voiding of warranty.
When service under the dock leveler is required,
always lock all electrical disconnects in the OFF
position after raising the platform and engaging the
maintenance prop.
