MAD-RAMPS Pivoting Ramp System
Installation Instructions
Step 8:
Adjust the Bumper Guard (part #9) forward or backward on the Main Arm to allow the Aluminum
Ramps (part #1 and #2) to travel through the Pivot Cages (part #7 and #8) and come to a rest just
below the Bumper Guard (Figure 21). This adjustment prevents the Aluminum Ramps from excessive
movement or contact with your truck’s bumper during transportation. This adjustment also serves as
a safety mechanism to prevent the Aluminum Ramps and the Pivot Cages from swiveling out of their
cradle positions when you are transporting your ATV/UTV. Once the Bumper Guard is positioned cor-
rectly, secure the Bumper Guard to the Main Arm (part #6) by tightening the two jam bolts. Tighten the
side jam bolt first and then the bottom jam bolt with a torque wrench to 70 ft/lbs each (Figure 22).
Step 9:
Install the Rear Marker Light (part #3) into the rear of the Main Arm (part #6), and align the pre-drilled
holes to allow for the retainer clip to be inserted (Figure 23). Insert the retainer clip to secure the Rear
Marker Light onto the Main Arm (Figure 24).
