Quick-Connect Fittings Maintenance and Best Practices
Damage to mating surfaces, dirt, and poor maintenance can defeat the couplings' fluid-tight seal.
⚠
WARNING
Perform regular daily maintenance on the Quick-Connect Couplings before lifting a vehicle:
•
Clean the couplings.
•
Inspect for Hydraulic leaks in
both the coupled and
decoupled state.
1. Clean the Quick-Connect Couplings. Dirt can prevent a liquid-tight seal and acts as an abrasive to
quickly wear the mating surfaces and damages internal O-rings. Dirty couplings will also introduce
contaminants into the hydraulic system, potentially damaging the pump and cylinder seals.
2. Prior to connecting or disconnecting the Quick-Connect Couplings, always remove pressure from
the hydraulic system by holding the down button for about five-seconds.
3. Do not attempt to force or pry the couplings apart with tools. The couplings are designed to
couple/decouple without the use of tools.
4. Never leave the Quick-Connect Couplings in a position where they may be run over by vehicles.
5. Replace damaged or worn Quick-Connect Couplings as required.
Disposing of Used Hydraulic Fluid
Used Hydraulic Fluid must not be disposed of by dropping it into the trash or dumping it into the
street. It contains toxic ingredients that are harmful to the environment.
Instead, you are required to either recycle it or drop it off at a hazardous waste collection facility.
First, note that there is a difference between dirty and contaminated Hydraulic Fluid:
Dirty fluid should be recycled, which is beneficial to the environment. Contaminated fluid cannot be
recycled; it must be disposed of at a hazardous waste collection facility.
Rags and/or granular absorbents that have soaked up Hydraulic Fluid should be treated like hazardous
waste and be disposed of at a hazardous waste collection facility.
To find an appropriate facility:
• Local automotive parts stores, auto care facilities, or automobile dealerships may accept fluid for
recycling or, in some cases, for disposal. Contact them for more information.
• Cities, counties, and states often support both recycling facilities and hazardous waste collection
facilities. Contact them to see if and where they have these programs.
• If you have large amounts of fluid, consider contacting a commercial waste disposal company. In
all cases, the best approach is to find an appropriate facility and contact them — in advance — to
ask them: what kinds of fluids they accept, what kind of containers it must be in, what hours they
are open, their location, and any other information specific to their facility.
If you are unable to find an appropriate facility, the website
be of help.
