Page 20: Creating Chalk Line Guides
Creating Chalk Line Guides Create Chalk Line Guides on the ground for the two Posts prior to moving them into position. Use the Width Overall value for your Lift model to determine where to place the Chalk Line Guides. The Width Overall value is the distance from the back of one base plate to the back of the other base plate.
Page 21 Attaching and adjusting equalizing cables It is much easier to fix both Equalizing Cable Ends into position before you stand up the Lift Posts. The Equalizing Cables keep the Lift Heads synchronized. If one Lift Head lowers or raises faster than the other Lift Head;...
Page 22 ⚠ CAUTION BendPak recommends wearing gloves while handling the Equalizing Cables. To install the Equalizing Cables in the GP-9LC Lift: 1. Using a forklift or equivalent, move the Posts near the Chalk Lines. 2. Place both Posts either flat on the ground or with their tops elevated on a sawhorse or similar; the insides of the Posts need to be accessible, facing up.
Page 23 5. Ensure that the threaded rod end pre-installed at the Carriage Lock Plate located inside each Lift Head is well secured. ⚠ CAUTION Failure to secure end properly may result in Lifting Chain failure or Lift malfunction. 6. Route the Cable upwards to the Top Plate Sheave. 7.
Page 24 9. Route the Cable around the bottom Sheave and up to the Lift Head. Re-install the Restrain Plate. 10. Insert the threaded end of the cable into the Lift Head. Use the Washer and Nut to loosely secure the cable end to the Lift Head – at this stage leave a lot of slack. 11.
Page 25: Anchoring The Posts
Make sure the shorter threaded rod ends of both the Equalizing Cables are securely fastened, tightening both nuts in place. Leave lots of slack for adjustment on the longer threaded rod end, as this will aide in final adjustment and decrease the need for to-and-fro. 12.
Page 26 Anchor Bolts do not meet these specifications, it could lead to product damage, Vehicle damage, personal injury, or even loss of life. BendPak Lifts are supplied with installation instructions and concrete fasteners meeting the criteria as prescribed by the latest version of the American National Standard “Automotive Lifts –...
Page 27 Effective Embedment is the location in the Hole where the Expansion Sleeve presses into the concrete. This is where the Anchor Bolts get their holding strength, the further down into the Hole, the greater the holding strength. Nominal Embedment is how far down into the Hole the bottom of the Anchor Bolt is, which does not tell you anything about the holding strength.

Page 30 Safeties and Safety Lanyards The GP-9LC Lift’s Safety system uses Safety Ladders and Safety Stop mechanisms to provide solid gravity-driven positive lock positions for the lift arms: there are 19 of these spaced every 3 in. (76 mm) and as the Lift Arms pass each position, the Safety Stops will make an audible sound as they engage, then rachet past them as you continue lifting.
Page 31 Your Lift is shipped with clean components; however, BendPak strongly recommends that you take secondary precautions and clean all loose 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.
Page 32 Hydraulic System Safety Warnings Before applying power to the Hydraulic System note the following Safety Warnings: ⚠ DANGER Failure to observe these warnings can result in serious personal injury including, in rare cases, death. ⚠ DANGER The Power Unit is a Hydraulic Pump capable of developing pressures in excess of 5,000 psi (345 BAR).
