O P E R A T O R S M A N U A L EZ-GLIDE SYSTEM ALUMINUM DROP DOWN LADDER RACK Read and understand all WARNINGS, DANGERS, NOTICES and instructions before assembly and installation. WARNING MODEL 251-3-02, 252-3-02 This product is only intended and only safe for transporting ladders. It is the responsibility of the user to secure these materials to the rack before transporting. Ladders must be secured per ANSI standard A142.2-1990 paragraph 8.4.4. Ladder damage will occur from road shock and vehicle vibration if the ladder is not properly secured to the ladder rack. Bouncing and side to side motion of an improperly secured ladder will cause wear and weaken the ladder. Using a damaged ladder could lead to structural collapse resulting in serious injury or death. Place ladder in a raised position before transporting. Driving with rack in lowered position may cause serious injury or damage to vehicle, ladder, rack or persons. Any modification or unintended use of this product shall immediately void all manufacturers warranties. Manufacturer disclaims all liability for injuries to persons or property resulting from any modification to, or unintended use of this product. Never load your rack to exceed the safe capacity of your vehicle. Heavy loads when carried high can dangerously alter the center of gravity. Loads should be approximately centered front to rear. Failure to do this will cause damage to the vehicle roof. Long loads that extend out the rear of the vehicle will prevent the rear hatch from fully opening and cause damage if attempted.
