Step 2 Install the leveling screws (8), screwing four (4) into each base. Step 3 Install the feed handles (1) and knobs (2) by screwing one knob onto the end of the handle, then slip thru hub and attach other knob. Step 4 Remove the Manta from the vacuum base by removing the nut and bolt that holds the main assembly to the vacuum base. Set the Manta aside, observing the following precaution. Turn the vacuum base over. Press the gasket into the groove in the underside of the base. The gasket is cut, at the factory, to the correct length, so that the two ends will butt together once the gasket is installed. Step 5 Assemble the two pieces of the water valve, and install the valve, into the water swivel, on the motor, just above the spindle (see motor literature). Plug the cord from the motor into the upper outlet on the meter box (the one opposite the motor on-off switch. The other outlet on the meter box is for the vacuum pump. Main Assembly CAUTION ! Feed Handle and Meter Box Vacuum Base Gasket Final Assembly The MK-Manta I Core Drill rig has been equipped with either a 20 Amp/115V 3 speed motor, a 20 Amp/120V 2 speed motor, or a 15 Amp/115V 2 speed motor. The drill should be used on an electrical circuit, separate from other loads, and protected by a 30 amp circuit breaker. The MK-Manta I has been provided with a 20 Amp plug (NEMA 15-20) or a 30 Amp (NEMA 15-30) locking plug depending on the model. The MK Manta is marked “Grounding Required” and has a three wire cord and three prong grounding plug. The plug must be connected to a properly grounded outlet (see figure below). If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk of electrical shock. The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool’s grounding systems and must never be attached to an electrically live terminal. Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in the figure to the left. Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the cord or plug is damaged. If damaged, have it repaired by an authorized service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician. The use of a circuit protected by a ground fault interrupter (GFI) is highly recommended. Use extension cords of the proper cable size, referring to the following chart. Cord Length 25 feet 50 feet 75 feetWire Size (AWG) #10 #8 #6 Never use an extension cord smaller than shown in the chart. Be sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it. Protect your extension cords form sharp objects, excessive heat and damp or wet areas. Notice: Using an extension cord with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage.

Extension Cords WARNING ! Securing the Rig A. Use a concrete anchor. Use either a 1/2 or 5/8 concrete anchor to secure the base to the work surface. Always be sure to level the rig. Using a concrete anchor, insert a bolt through the slot located on the base and tighten the bolt firmly in the anchor. It is essential to always secure the rig to the work surface to help prevent personal injury and also to protect the rig. An unsecured rig could rotate during drilling and possibly cause injury. It could also cause the bit to chatter against the work surface or bind in a hole, which can fracture the diamond segments. B. Vacuum base. The MK-Manta I Core Drill Rig is equipped with a vacuum base. This base is designed to provide approximately 1800 pounds of total holding power. In order to provide the most rigidity to your core rig the unit should be used on a relatively smooth surface such as concrete. (If the surface is too porous or rough the vacuum mount may not hold securely.) 1. Turn the vacuum pump on and step on the vacuum base until a vacuum is created and the base adheres to the work surface. 2. Level the rig using the leveling bolts. Use a minimum amount of adjustment to the leveling bolts to avoid breaking the vacuum seal. The vacuum gauge...
