Page 27 Create a Floor Plan Make sure to plan out, in advance, where the Lift and Console are going to go: • Clearance. Make sure there is clearance on all sides and above the Lift site. • Console. The Console must be near the Lift; it can be installed on either the left or right side but only on the cylinder end of the Ramps.
Page 28 Be sure to leave the Lift on a Safety Lock when Hydraulic Hose, Air Line, and Return Line. you raise it. Important: BendPak recommends using the Eye Bolt that comes with the Lift to raise the Platforms off the Bases. ⚠ at least three people...
Page 29 3. When the Platform gets above the top Safety Lock, lower it back down onto the top Safety Lock. Leave it on the top Safety Lock. 4. Remove the Eye Bolt from the first Platform, install the Eye Bolt on the second Platform. Perform the same procedure on the second Platform.
Page 30 About Effective Embedment Anchor Bolts (also called Wedge Anchors) get their holding strength from how far down into the Hole the Anchor Bolt’s Expansion Sleeve presses into the Concrete (called Effective Embedment) and how forcefully the Expansion Sleeve presses into the Concrete (based on the width of the hole and how much Torque is applied).
Page 31 Each Ramp Assembly Base has four holes MDS-6EXT/F or three holes on the MDS-6LP/F for anchoring to the Concrete. Before you anchor your Lift, make sure the two Platforms are correctly aligned. BendPak recommends double checking the work done when creating your Chalk Line Guides.
Page 32 1. Make sure the Ramp Bases are where you want them. Once you anchor the Bases into place, it is difficult to change the location. Once the Anchor Bolts are torqued into position, they are not easily removed. BendPak strongly recommends making sure the Bases are in the correct location before anchoring the Bases into place.
Page 33 4. Insert an Anchor Bolt with Washer into each hole, then tap it down into the hole. 5. Make sure the Washer and Nut are in place, then insert the Anchor Bolt into the hole. The Expansion Sleeve of the Anchor Bolt may prevent the Anchor Bolt from passing through the hole in the Base;...
Page 34 Assemble and Anchor the Console The Hydraulic Hoses, Air Line, and Return Line require the Console to be within 40 inches of the cylinder end of the Lift on either the left or right side. If you want to set up the Console further than 40 inches from your Lift, you will need to have Hydraulic Hoses fabricated that are long enough to reach the Lift from the desired location.
Page 35 3. Open the Power Unit Console Box and retrieve the Rear, Left Hand and Right Hand sides of the Console as well as four M6 x 12mm Hex Head Bolts. 4. On a flat level surface, place cardboard or rags down to prevent marring the paint and assemble as...
Page 36 There are four mounting holes in the bottom flange of the Console. You only need to Note: anchor two of the four holes. BendPak recommends installing them diagonally from each other; one in the front right, the other in the left rear, for example.
Page 37 Even using a hammer or mallet, the Anchor Bolt should only go into the hole part of the way; this is normal. If the Anchor Bolt goes all the way in with little or no resistance, the hole is too large. Once past the hole in the Console Base, the Anchor Bolt eventually stops going down as the Expansion Sleeve contacts the sides of the hole;...
Page 38 To mount the Power Unit: 1. Find the four supplied M8 x 20 Hex Head Bolts from the Console packaging. The Power Unit is heavy. BendPak recommends having one person hold the Power Unit while a second person bolts it into place.

Your Flow Divider may look differently, but it will also have one input connector and two output connectors, as shown. The Console is on the Left in the drawing. Not to scale. Not all components shown. Some components exaggerated for clarity.
Page 43 To connect the Hydraulic Hoses: 1. If the Platforms are not already engaged on their top Safety Locks, raise them now, using a Shop Crane or Forklift. Refer to Lift the Platforms off the Bases additional information. 2. If the front and top of the Console are in place, remove them.
Page 44 7. Locate the Long and the Extra Long Hydraulic Hoses. 8. Connect the Long and Extra Long Hydraulic Hoses to the two connectors on the Flow Divider. It does not matter which line connects to which output connector on the Flow Divider. Finger tighten the connections.
Page 45 Working with Compression Fittings and Tubing Your Lift comes with ¼ inch, black, polyethylene Tubing (also called Poly-Flo® Tubing) that is used with Compression Fittings to create the Air Lines and Return Line (Cylinder Vent). This section covers Important: Compression Fittings are not the same as Hydraulic Fittings. Compression Fittings only The components involved with Compression Fittings include: •...
Page 46 Connect the Air Lines The MDS-6 Series Lifts must be raised off the Safety Locks using Hydraulic Power, then air pressure is used to release the Safety Locks so you may lower the Platforms. It is the responsibility of the Lift owner to provide an air pressure supply (minimum 50 psi / 10 CFM, regulated to a maximum of 125 psi).
Page 47 Tee branches the air off to the first Lift Frame Air Cylinder and also to the second Lift Frame Air Cylinder. before BendPak recommends planning out the path of the Air Line you start cutting the Tubing. 3. Feed the Air Line tubing from the Console to the First Lift Frame.
Page 48 Connect the Return Lines The Return Line returns Hydraulic Fluid from the Hydraulic Cylinders to the Power Unit’s Hydraulic Fluid Reservoir. Create the Return Line using the ¼ inch black plastic Tubing that came with the Lift; you need to cut it into sections of the appropriate length.
Page 49 4. Attach an Elbow Compression Fitting with a 3/8 NPTF to one of the Return Line Ports (Cylinder Vent) on the Power Unit. There are two Return Line connectors on the Power Unit; they work the same, so choose the one that is best for you.
