Hydraulic fluid contamination is a critical issue for your Lift. Contaminants like water, dirt, or other debris can infiltrate the hydraulic hoses and fittings, potentially rendering your new Lift inoperative. While your Hydraulic Repair Near Me Lift is delivered with clean components, we highly advise a secondary cleaning of all hydraulic hoses and fittings before connection. This preventive step is cost-effective and avoids future service interruptions due to preventable issues.

There are various methods to clean Hydraulic Repair Near Me hydraulic hoses and fittings:

  • Use compressed air to expel contaminants from each hose and fitting before installation. Opt for clean, dry air and always wear eye protection. Never direct the air hose nozzle towards any person or body part.
  • Fluid flushing can be effective if the hydraulic fluid used is clean and compatible with the system. Ensure the fluid itself is free of contaminants.

Additional measures to maintain hydraulic fluid cleanliness include:

  • Removing old thread seal tape from temporary plugs in Hydraulic Repair Near Me hydraulic cylinders.
  • Using liquid thread sealants like Teflon paste-type or Loctite™ 5452 for NPT fittings, avoiding over-tightening which can lead to cracking. Avoid thread seal tape on JIC or ORB O-ring fittings.
  • Keeping transfer equipment clean to prevent contaminant introduction.
  • Storing hydraulic fluid properly in a clean, cool, and dry environment, sealed until use.
  • Capping hoses and fittings before installation to prevent exposure to contaminants.
  • Filtering new hydraulic fluid, even with a heavy-duty nylon mesh screen, to ensure cleanliness.
  • Avoiding the mixing of different hydraulic fluid types, and flushing the Hydraulic Repair Near Me system before adding replacement fluid.

For applying thread sealants:

  • Clean and dry fittings and connectors before application.
  • Apply a small amount to the first four threads, skipping the top thread, and wipe any excess.
  • Tighten the fitting without over-tightening.
  • Allow for a 24-hour curing period before pressurizing the system.

When installing the Hydraulic Repair Near Me hydraulic hose, ensure all components are prepared as per the above guidelines. The process includes attaching fittings to the hydraulic cylinder and routing the hose through retaining rings and flex tube openings, leaving the curved end near the power unit.


Setting Up the Return Line:

The Return Line’s purpose is to redirect excess hydraulic fluid from the Hydraulic Cylinder back to the Power Unit’s Fluid Reservoir.

Required Components for Return Line Installation:

  • A single piece of ¼ inch black polyethylene tubing, included as part of the Return Line (Item 5570795), with elbow compression fittings at both ends. You’ll need to cut a segment from the supplied tubing to the correct length for the Return Line.
  • Two COMP to NPT Hydraulic Elbow Fittings (Item 5550089), where the COMP end links to the Return Line and the NPT end attaches to the Power Unit and Hydraulic Cylinder.

Note: The Return Line’s tubing is identical to that used for the Air Lines. Ensure not to mix them up as they have distinct functions.

Installation Steps for the Return Line:

  • Measure the distance between the Return Line Port on the Hydraulic Cylinder and the corresponding port on the Power Unit.
  • Cut the tubing to your measured length, erring on the side of longer rather than shorter.
  • Lead the tubing from the Hydraulic Cylinder through the Flex Tube opening, positioning it near where the Power Unit will be installed.
  • Remove the Shipping Plug from the Hydraulic Repair Near Me Hydraulic Cylinder’s Return Line Port and attach the Compression Elbow Fitting (5550089). Apply Thread Sealant only on NPT threads.
  • Connect one end of the Return Line to the COMP end of the Fitting, following guidelines for working with compression fittings and tubing.
  • For now, leave the other end of the Return Line protruding from the Flex Tube opening.

Setting Up the Air Line:

The Air Lines, made of the same ¼ inch black polyethylene tubing, are vital for disengaging the Safety Locks in each Post, enabling the lowering of the Runways. These lines require an air supply (3 to 25 cfm at 50 — 150 psi) to function, but be cautious not to exceed 150 psi to prevent potential hazards.

Installation Steps for the Air Lines:

  • Gather the supplied tubing and three Air Line Tee Fittings.
  • Measure and cut seven tubing pieces based on the provided diagram.
  • Attach these tubing segments to the Tee Fittings on the Lift as per the diagram.
  • Ensure the long tubing piece under the Powerside Runway is routed through the Steel Tubes to avoid interference with cable routing.
  • Temporarily leave the Air Line’s Power Unit end extending from the Flex Tube opening. It will later be connected to a Tee Fitting and the Pushbutton Air Valve.

Note: Do not interchange the Air Lines with the Return Line despite their similar appearance and tubing. Incorrect connections can lead to malfunctioning Safety Locks. If any tubing becomes disconnected, cease using the Lift and repair the Air Lines.

Setting Up the Power Unit for Your Lift:

This guide outlines how to install the Power Unit for your Lift, excluding its connections to the power source. A qualified electrician is necessary for making the power connections.

Hydraulic Repair Near Me Installation Process:

  • Identify the Power Unit, Vibration Dampener, and the provided installation hardware.
  • Align the mounting holes on both the Power Unit’s Mounting Plate and the Vibration Dampener with the selected Mounting Bracket’s holes. Ensure all four holes on each component are used for a secure installation.
  • Fasten the Power Unit and Vibration Dampener to the Mounting Plate using the supplied hardware.

Safety Precautions:

  • The Power Unit is substantial in weight. It is recommended that one person holds the unit while another secures it to the bracket.
  • As there’s a risk of explosion due to internal arcing or spark-generating parts within the Power Unit, it must not be exposed to flammable vapors, rain, or damp environments. Try to avoid damage from moisture. 

Note: The Power Unit included with your Lift might vary slightly from the illustrations in the manual to accommodate different applications.

Filling the Hydraulic Fluid Reservoir:

The Hydraulic Fluid Reservoir of the Power Unit requires approximately 3.6 gallons (13.5 liters) of hydraulic fluid for optimal operation..
