ST-2 STIHL Backpack Blower Rack Installation Instructions

Thank you for purchasing a TrimmerTrap product. This product was designed and manufactured to provide many years of service while helping protect your investment. The ST-2 rack is designed to hold the STIHL BR 500 and 600 series blowers only. The STIHL BR 300 and 400 series require the ST-1 blower rack. This rack consist of two basic parts, a vertical upright post with "U" shaped solid round stock welded to it and the "sliding lip" with a threaded female barrel welded to it. Hold the upright so that the solid round protrusions face up (the holes in the tubing will be on the top) and so that the side of the upright that the solid round bar is welded to is facing you. Slide the "sliding lip" over the top of the rack with the "lip" facing down and the threaded barrel to the right. The backside of the blower (recoil starter side) will face away from the rack when the rack is installed with the latch mechanism to the right. This is the most common method for open trailers and trucks and the only method for enclosed trucks and trailers. Fasten the vertical upright of the rack to the upper and lower rail of the trailer using the two bolts and self locking nuts provided. If installing the ST-2 in an enclosed truck or trailer shims/spacers will have to be used to space the upright approx. ½ inch from the wall in order for the "sliding lip" to function. Be certain to center the holes when drilling the vertical post. Install the two round vinyl tubes onto the ½" round bar that the blower rest on. Install the flat caps onto the "sliding lip". NOTE: To ease installation of the protective covers place them in a sink and run hot water over them for a couple of minutes. Install the plastic end-cap into the top end of the square tube. Tightly hold the tapered pin of the latch with pliers or vise and securely tighten the ball knob to the pin. Next screw the threaded latch assembly into the threaded barrel on the "sliding lip" assembly and tighten. NOTE: A two part thread locking compound has been pre-applied to the threads of the latch and will be activated when screwed into the threaded barrel. Position the "sliding lip" on the post so that the latching pin engages the top hole in the upright. After positioning the "sliding lip" on the post install the self-tapping screw into any one of the four sides of the post ½ inch from the top of the post. The screw will prevent the "sliding lip" from sliding off of the post. The ST-2 is now ready for use. The STIHL 500 and 600 series blowers have recesses in the bottom of the frame. Two of these recesses will be utilized to help secure the blower to the rack. By inspecting the bottom of the frame and noting where the backpack straps attach you can identify these two recesses. Pull and hold the backpack straps tight so that the plastic buckles that secure the straps to the frame are flat against the frame. Tightly install a nylon tie to each strap on the opposite side of the frame as the buckle and cut off excess tie. The tie will hold the strap in place and prevent it from sliding back through the slot interfering with the stud on the rack. The blower can now be installed onto the rack. Hold the blower by the top handle with the recoil starter facing towards you and tilt the top of the blower back towards you. Set the bottom of the blower onto the rack so that the racks two studs engage the recesses identified in the blower frame. Next tilt the blower towards the rack so that the opening under the blowers handle slides over the "lip" on the "sliding lip". You can now pull the ball knob and lower the "sliding lip" until the latch engages the bottom hole of the upright. The "lip" should now be extending down over the blower frame securely latching it in place. IMPORTANT: Be certain the latch is fully engaged into the upright! The top hole in the rack serves two purposes. To position and hold the "sliding lip" in the up position when the blower is removed. And it accepts a long shackle padlock when the "sliding lip" is in the lower position to help prevent theft.
