Use and Care Manual

10AP Series Two-Post Lifts 27 P/N 5900265 — Rev. A10 — September 2023
IMPORTANT! PLEASE READ NOW
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 and unusable.
Your Lift is shipped with clean components; however, BendPak strongly recommends that you take
secondary precautions and clean all Hydraulic Hoses and Fittings prior to making connections. It is
better and less costly to take these extra steps now so that you do not need to take your Lift out of
service later to fix issues that could have been prevented at the time of installation.
There are several ways to clean 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 ANSI-approved eye protection
(safety glasses, goggles, or face shield) when using compressed air for cleaning. Never point an air
hose nozzle at any part of your body or any other person.
• Fluid Flushing. If the Hydraulic Fluid is clean and compatible with the system fluid, you can 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. Liquid thread sealant (Loctite™ 5452 or similar) is
recommended. Do not use thread seal tape on any fitting. Liquid thread sealant is recommended
for NPT connections, fine for JIC connections, but not necessary for O-ring (ORB) connections.
• Always use clean equipment. If you use a dirty bucket or funnel to transfer the Hydraulic Fluid
into the Hydraulic Fluid Reservoir, 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 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 you add the replacement
Fluid; do not mix the two together.
