Gorilla-Lift™ Trailer Tailgate Lift Assist

Model # 40101042G

! WARNING !

Always pin, latch or lock the tailgate in its upright position;

this product is not a substitute for always doing so.

This product does not make the tailgate weight bearing;

the opened tailgate must always rest on firm ground.

Never raise or lower the tailgate while

anyone or anything is under the tailgate.

Keep hands away from all openings,

rollers or cables when product is in use.

! CAUTION !

Due to the many different sizes, weights and designs of trailers and tailgates on the market today, some minor

adjustments may be necessary to insure your Gorilla-Lift™ works properly. Extreme caution must be taken

during and after the initial installation of your Gorilla-Lift™ to insure that it is working properly. Always lock your

tailgate in upright position before installing, adjusting or working on the Gorilla-Lift™. Check to make sure there

is not too much or too little lifting-power on your tailgate. Never force the tailgate up or down: it should travel

with very little effort in both directions. Always make sure that the rollers are turning freely, and that the cable is

in good condition and travels in the grooved portion of the rollers as it operates.

Always make sure that the trailer’s tailgate is pinned, latched or locked when in its upright position. IMPORTANT: If the top of your trailer’s side rail is made of ROUND TUBING LARGER THAN 2-INCHES IN DIAMETER, you will either need longer carriage bolts before beginning installation or you can spot-weld the Gorilla-Lift™ on the side rails instead of drilling holes and using carriage bolts. STEP 1, ATTACHING TO THE TOP OF THE TRAILER’S SIDE RAILS: 1) Begin with the driver’s side of the trailer.

) Raise the cable and place a roller under it allowing the cable to rest in the groves; then insert a 1/4-inch clevis pin into the bottom hole at the angled end of housing A; next run it through the roller that you just positioned and out the other side of the housing. 4) Slide TWO 1/4-inch flat washers onto the clevis pin; then, using the needle nose pliers, secure the clevis pin in place with a 1/4-inch locking ring.

) If there is too much lifting-power on your tailgate, please follow steps I, II and III below in order: I. Lower the point at which you have the cables attached to your tailgate a little at a time and test lifting-power, but never low enough to allow ANY slack in the cables. Keep cables the same height on both sides of tailgate. II.

Step 4B (attaching to tailgate without S-Hooks): We recommend using S-Hooks. Measure the complete height of your tailgate. Using the chart below as a guide, measure from the top of your side rail up along the side of your tailgate and make a mark.
