Hydraulic Fluid Contamination
Hydraulic Fluid Contamination poses a serious issue for your Lift; contaminants such as water, dirt, or
other debris can get into the Hydraulic Hoses and Fittings on the Lift, making your new Lift inoperable.
Your Lift is shipped with clean components; however, BendPak strongly recommends taking
secondary precautions and cleaning all Hydraulic Hoses and Fittings prior to making connections. It is
better and less costly to take these extra steps now to avoid taking the Lift out of service later to fix
issues that could have been prevented at the time of installation.
Cleaning Hydraulic Hoses and Fittings:
• Compressed Air. Use an air compressor to blow out contaminants from each Hydraulic Hose
and Fitting prior to installation. Clean, dry air is preferred. Wear eye protection (safety glasses,
goggles, or face shield) when using compressed air for cleaning. Never point an air hose nozzle at
any part of yourself or any other person.
• Fluid Flushing. As long as the Hydraulic Fluid is clean and compatible with the system fluid,
flush Hoses and Fittings to create turbulent flow and remove particulates. Always ensure that the
fluid itself is contaminant-free.
Some additional steps that will help keep the Hydraulic Fluid clean:
• Remove old thread seal tape. Some ports on the Hydraulic Cylinders are shipped with
temporary plugs secured with thread seal tape, so make sure to thoroughly remove any leftover
thread seal tape that may inadvertently enter the Hydraulic System.
• Use a liquid thread sealant only. Teflon paste-type thread sealant or Loctite™ 5452
thread sealant is recommended for all NPT Fittings. Do not overtighten NPT Fittings or they may
crack. Never use thread seal tape on JIC Fittings or ORB O-Ring Fittings.
• Always use clean equipment. If a dirty bucket or funnel to transfer the Hydraulic Fluid into
the Hydraulic Fluid Reservoir is used, the contaminants will likely be introduced into the Fluid. When
using cleaning rags, use a lint-free rag.
• Proper storage. Keep the Hydraulic Fluid sealed in its container until ready for use; store the
Fluid in a clean, dry, and cool area.
• Cover the Hoses and Fittings. Before installation, do not leave the ends of the Fittings
exposed; the same applies for the Hydraulic Hoses. As a general rule, keep the Hydraulic Hoses
and Fittings capped and kept clean in a clean area until ready for use.
• Filter the new Hydraulic Fluid. Just because it is new does not necessarily mean it is
clean. Use an offline filtration cart or kidney loop system to make sure the Hydraulic Fluid is clean
before being transferred into the Hydraulic Fluid Reservoir (even using a heavy duty nylon mesh
screen is better than trusting what is left at the bottom of the barrel).
• Avoid mixing different types of Hydraulic Fluid. If Hydraulic Fluid needs to be
replaced, make sure to flush the Hydraulic System of the old Hydraulic Fluid before adding the
replacement Fluid; do not mix the two together.
