If the beam measures 8”, contact product safety at [email protected] to have the kit excluded. VMV000028 has been created to provide the necessary parts and instructions to add a plate gusset to reinforce the trailer frame. The kit must be installed as soon as possible. Special tools and conditions:  None Shutdown procedure Stopping the machine For your safety and the safety of others, follow shutdown procedure before working on the machine for any reason, including servicing, maintaining, cleaning, inspecting, unclogging or transporting machine, or as otherwise directed in Operator’s manual. Step 1: Make sure end of vacuum hose is clear of all spoils, debris, and other materials. Step 2: Turn Water Pump Switch to OFF. Step 3: Push Throttle Switch to SLOW. Idle engine five minutes to allow vacuum pump to cool down. This helps to prevent the buildup of condensation. Step 4: Turn key switch to OFF to shut off engine. Remove the key. Step 5: Pull trigger on any high-pressure water tool to relieve line pressure. Step 6: Disassemble all water line connections, vacuum hoses, and tools. Stow properly on machine. Step 7: Drain CVS Filter Housing / Cyclone. WARNING: Use the following shutdown procedure before attempting to do any of the work described in this Kit. VMV000028 Rev. 1 9 March 2023 Page 3 of 8 Procedure 1: 1. Measure the height of the I-Beam indicated by the green arrows in the enlarged balloon of Figure 1 below. If it is 8” tall, no change is required. If it is 6” tall, proceed to Step 2. 2. Refer to Figure 1 for parts list. WARNING: Pressurized fluid can penetrate body tissue and result in death or serious injury. Leaks can be invisible. Keep away from any suspected leak. Relieve pressure in the hydraulic system before searching for leaks, disconnecting hoses, or performing any other work on the system. If you must pressurize the system to find a suspected leak, use an object such as a piece of wood or cardboard rather than your hands. When loosening a fitting where some residual pressure may exist, slowly loosen the fitting until oil begins to leak. Wait for leaking to stop before disconnecting the fitting. Fluid injected under the skin must be removed immediately by a surgeon familiar with this type of injury. VMV000028 Rev. 1 9 March 2023 Page 4 of 8 3. Remove the conspicuity tape (A) and “Water Tank Drain” decal (B) from the roadside I-beam. 4. Identify the location where the gusset (1) (p/n 135006180) will be welded onto the roadside I-beam. Grind the I-beam and all weld surfaces to remove paint prior to welding. 1 A B VMV000028 Rev. 1 9 March 2023 Page 5 of 8 5. Use a weld blanket to protect the fuel tank and hoses behind weld location. 6. Position the gusset (1) (shown on previous page) on the I-beam and weld per the specifications shown in “DETAIL B” below. 7. Grind all welds and weld splatter. Clean all surfaces on the I-beam, gusset, and fenders. Paint all exposed surfaces. Allow paint to dry thoroughly. 8. Clean the areas where conspicuity tape and decal will be applied with soap and water. Allow to dry thoroughly. VMV000028 Rev. 1 9 March 2023 Page 6 of 8 9.
