ROTA LIGHT BAR CUTTING INSTRUCTIONS

1. Two people will be needed to complete this task.

2. Place ONLY THE MOUNTING END CASTINGS with the Rubber Booties into the
rain-gutters of your vehicle.

3. Level each Mounting End Casting so that the top flat area is parallel to the horizon.

4. Take a tape measure and measure the distance between each open end of each
Mounting End Casting.

5. From that dimension subtract 4 inches.

6. Subtract that total from the total length of the bar, which is 56".

7. Take the difference and divide it by two.

8. The amount divided by two is the amount you will cut off each end of your bar.

9. Measure and mark a line on both ends of the steel bar using the above dimension
you have just figured.

10. Clamp one end of a bar into a vise. (Be careful not to scar the light bar).

11. Using a hacksaw, cut carefully along the marked lines. (If a vise is not available, put
the bar on a table, secure tightly and cut).

12. Repeat steps 9-11 to cut the other end of the bar.

WARNINGS!

> Do not over tighten the nuts and bolts or damage to the castings and or stripping of the threads could result.

> FOR SAFE AND PROPER USAGE OF THIS PRODUCT, THE MOUNTING INSTRUCTIONS MUST BE FOLLOWED CAREFULLY AND COMPLETELY.

> The manufacturer and distributor of this product are in no way responsible for the consumer’s failure to adhere to the warnings and directions of these instructions in the event of damage to the consumer’s vehicle, other properties and or personal injury.

> DO NOT REMOVE the PVC tape from the light bar until cutting is completed. When cutting black bar leave plastic bag on and wrap a rag around bar before putting into a vise so no scratching of paint will result. Remove the PVC tape from the brackets (does not apply to black brackets). The light bar will not tighten properly unless the bar is straight across the cab.

1. IMPORTANT: Cut the crossbar FIRST before proceeding to the next step! Refer to the Rota Light Bar Cutting Instructions on the other side.

2. Place the black plastic booties on the feet of each casting.

3. Take the long 3/8" socket bolt and screw on to it the 3/8" jam nut all the way to the end of the threads and tighten down.

6. Place casting (2) inside of casting (3) and line up the two 5/16" holes.

7. Take the 5/16" Allen head screw and put it through both castings (3) and (2). Use the 5/16" washer and 5/16" nylon lock nut to securely tighten castings.

8. NOTE: THE FRONT FACE OF CASTING (2) SHOULD BE STRAIGHT ACROSS THE FACE OF CASTING (3). When the castings are securely tightened together, casting (2) should be protruding approximately 1/16" beyond casting (3).

9. Place a 3/8" flat washer on the long 3/8" socket bolt and now put the long socket bolt through the other hole in casting (2).

10. Place casting (1) on casting (2).

11. With the welded nut washer facing away from casting (2) place it all the way to the inside of casting (1).

12. Screw the long 3/8" socket bolt into the washer with the welded nut all the way, and lightly tighten. NOTE: Use the 5/16" Allen wrench through the largehole in casting (3) to tighten and loosen the rotating motion.

13. Repeat steps 1 through 11for the other side.

14. With the holes in the bar, in the up position, take casting (1) and by squeezing the end of the bar, place casting (1) on the bar, until the inside top wall of the casting is flat against the bar.

15. Take a 5/16" Allen head screw and put it through the hole in casting (1), and the slot in the bar, with the head of the screw in the up position.

16. IMPORTANT: For some trucks when the bar is cut and put into casting (1), there may not be a slot left in the bar. If this is true, follow the next 11 steps.

a. With the black booties on the back of casting (3), place the entire casting assembly into the rain gutter of the vehicle.

b. Position the foot of the “L” shaped steel brackets underneath the rain gutter and line up the vertical slot of the bracket with the tapped hole in the casting. Insert (2) ½" tamper proof Allen head bolts with lock washers through the “L” bracket securing the bracket to the support casting.
DO NOT TIGHTEN

c. Place a screwdriver through the desired horizontal slot in the steel bracket, at the same time put the screwdriver into one of the three slots provided in the casting. (Proper selection of the slots in the bracket and the slots in the casting will result in a tighter fit on the vehicle).

d. Push the screwdriver against the casting and pry up against each bracket, one at a time, until both the casting and brackets are tightly secured in place. Tighten the two Allen head bolts. CAUTION: Prying up excessively could result in bending of the bracket or stripping the slots in the castings.

e. Follow the same procedure in steps a, b, c, and d, to secure the other casting to rain gutter.

f. By squeezing the ends of the bar put the bar back inside of casting (1).
