MODEL 284 EZ-GLIDE SYSTEM 10' HIGH CUBE VAN DRIVER SIDE ALUMINUM DROP DOWN LADDER RACK ATTENTION Read and understand all instructions and warnings before operating or using this product. WARNING 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. NOTICE 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. CAUTION 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.

VEHICLE MOUNTING PROCEDURE 11
Unit will need to be placed on roof in a position where the handle will be between 3" - 6" behind van. There are a few preliminary steps you need to take to make sure you use the correct holes in mounting base. THIS RACK WAS DESIGNED TO FIT VANS WITH ROOF RIBS SPACED 24" APART. IF YOUR VAN DOES NOT HAVE THIS SPACING, YOU MUST SUPPLY PROPER REINFORCEMENT ON IN- SIDE OF VEHICLE. Might have to flip ends to get needed dimension Large holes Roof Ribs STEP 15 Place a Mounting Base up on roof with the two large holes facing up. These two holes will be used to mount to the roof ribs. One of the three small holes will be used to mount the rotation kit to the Mounting Base. Mounting Base Small holes 22-1/2" - 25-1/2" STEP 16 Line up large holes so they are centered on roof ribs closest to the back of the van. To get proper handle clearance of 3" to 6" from the back of van, you will need to locate one of the small holes so that it is between 22-1/2" to 25-1/2" from hole to back of the van (See Illustration). It may be necessary to rotate mounting base so a small hole is in that range. 3" - 6" Back of van (2) 5/16-18 x 4" Hex Hd. Bolt Mounting Tube STEP 17 After you have found the correct small hole, remove Mounting Base from roof and attach rear end of Rotation Kit to the Mounting Bases using 5/16-18 x 4" long Hex Hd. Bolt. Flat Washer and Nylon Lock Nut will mount through large hole on bottom, onto bolt. (2) 3/8 Flat Washer (2) 5/16-18 Nylon Lock Nut 12 (2) Mounting Base 13
STEP 18 Determine what small hole to mount Front Rotation with after lining Mounting Base up with Roof Ribs toward front of van. Attach Front Rotation Assembly to the Mounting Bases with 5/16-18 x 4" Hex Hd. Bolts. Flat Washer and Nylon Lock Nut will mount through large hole on bottom onto bolt. (2) 5/16-18 x 4" Hex Hd.

Check to verify that the Handle clears the rear of the van. 13 14
STEP 20 (4 Places) With unit centered side to side, mark the holes in the Mounting base (A). Move the unit out of the way enough to drill the 5/16" dia. holes. Reposition unit and secure to the van roof with the 5/16-18 x 1-1/4" Fasteners. CAUTION To keep debris out of your eyes when drilling, always wear protective eyewear. NOTE: Seal the top of the bolts that go through the roof with the sealant that is supplied. (8) 5/16-18 x 1-1/4" Hex Hd.

FINAL ASSEMBLY 15
LADDER & CYLINDER ADJUSTMENTS STEP 22 Using the handle rotate rack to the down position. Because the ladder rack is not under the load of a ladder, you may have to pull the front and rear rotation assemblies down by hand after moving the handle to the down position. STEP 23 Actuating the release mechanism on the rear slide down, lower the assembly. Place the ladder onto the ladder rack and raise only the rear slide down to the upper position. Do not rotate the rack to the up position at this time. RELEASE CAUTION Once the release lever is pushed, you must support the full weight of the ladder and the ladder slide. UP DOWN HANDLE ROTATION LADDER STOP RELEASE LADDER SUPPORT UP REAR SLIDE DOWN STEP 25 Adjust the flow control screw on the cylinder per the instruction decal on the drive shaft handle tube until the ladder operates smoothly as you rotate the ladder up and down. DOWN 16 STEP 24 With the side of the ladder sitting on the ladder support of the rear slide down assembly in the up position, adjust the ladder stop so that it is approximately 1/4" above the ladder and tighten the fastener firmly.
