Park the vehicle close behind the Western snow plow blade, quadrant and A-frame assembly so the ears line up with the couplings on the lift-mount assembly.
Grasp the chain and hook it to the lift channel.
Enter the cab and use the control to raise the lift channel so it lines up. Monitor the outside of the cab and keep people away.
Exit the cab and insert the hitch pins and hairpin cotters, attach any hydraulic hoses from the truck to the rams on the A-frame.
Go back into the cab and move the control to the lower float position.
From the outside again, push the lift channel all the way down. Tighten the chain by pulling it.
