13 CALL YOUR ONE-CALL SYSTEM FIRST WARNING: Electricity or gas explosion can kill. Laser light in cut cable can result in eye damage. Locate utilities before drilling. Call 811 or (U.S. or Canada) or local utility companies or national regulating authority. Before you start any digging project, don t forget to call the local One-Call system in your area and any utility company that does not subscribe to the One-Call system. For areas not represented by One-Call Systems International, contact the appropriate utility companies or national regulating authority to locate and mark the underground installations. If you don t call, you may have an accident, suffer injuries, cause interruption of services, damage the environment, or experience job delays. The One-Call representative will notify participating utility companies of your proposed digging activities. If you are in the U.S. or Canada, and do not know the number for the local One-Call representative in your area, you can dial the North America One-Call number for this information. Utilities will then mark their underground facilities by using the following international marking codes: Red...Electric Yellow...Gas, Oil or Petroleum Orange...Communication, Telephone, TV Blue...Potable Water Green/Brown...Sewer White...Proposed Excavation Pink...Surveying Catamount Safety Messages 10-13

14 UNDERGROUND UTILITY CONTACT WARNING: Contact with buried utilities can cause death or serious injury. Cut electric cables can shock or electrocute. Ruptured gas lines can cause fire or explosion. Laser light from cut fiber optic cables can cause serious eye damage. Before excavating or drilling, contact the local One-Call system and any utility company that does not subscribe to the One-Call System, to locate all buried utilities in and around the proposed excavation or bore. OSHA CFR requires that the estimated location of underground utilities be determined before beginning the excavation or underground drilling operation. When the actual excavation or bore approaches an estimated utility location, the exact location of the underground installation must be determined by a safe, acceptable and dependable method. If the utility cannot be precisely located, it must be shut off by the utility company. Before excavating or boring, contact the One-Call System to locate all buried utilities in and around the bore path. Select a boring path that will not intersect buried utilities. Never bore on a path toward electric or gas lines. If the utility cannot be precisely located, have the utility company shut it off before starting any underground work Safety Messages Catamount

15 PERSONAL PROTECTION Wear required personal protective equipment. Wear close fi tting clothing and confi ne long hair. Avoid wearing jewelry, such as rings, wristwatches, necklaces, or bracelets. Always wear: Safety glasses Work shoes Hard hat High visibility clothing when working near traffi c (safety vest) Hearing protection CHECK LAWS AND REGULATIONS Know and obey all Federal, State, and local laws and regulations that apply to your work situation. DO NOT WORK IN TRENCH Do not work in trench with unstable sides which could cave in. Specifi c requirements for shoring or sloping trench walls are available from several sources including federal and state O.S.H.A. Offi ces. Be sure to contact suitable authorities for these requirements before working in the trench. Catamount Safety Messages 10-15

16 Keep Spectators Away From Machine Keep all spectators and other workers away from the machine and work area while in operation WORK IN VENTILATED AREA Exhaust fumes can be fatal. If operating the machine in a closed area, remove the exhaust fumes with an exhaust pipe extension to the outside Safety Messages Catamount

17 KEEP MACHINE IN GOOD CONDITION Be sure the machine is in good operating condition and that all safety devices are installed and functioning properly. Visually inspect the machine daily before starting the machine. Refer to the daily pre-starting inspection section. Make no modifi cations to your equipment unless specifi cally recommended or requested by Vermeer Manufacturing Company. Confined Space Regulation Do not work in a confi ned space, such as a sewer, until requirements are met to ensure a hazard free environment. Specifi c requirements for confi ned space entry are available from federal and state OSHA offi ces. Catamount Safety Messages 10-17

18 CLEAR WORK AREA Clear the work area of all objects that might interfere with the proper operation of the tool or hoses. Avoid placing tools or other objects where they can fall into the boring pit. HANDLING THE BORING TOOL To avoid back injury, use proper lifting technique. Lift with your legs - not you back! CHECK HARDWARE Ensure all airline couplings are tightened and secured to eliminate the chance of accidental uncoupling. Use hose connection retaining devices such as locking rings, clips, pins, chains, or cables. CHECK AIR COMPRESSOR Be sure the air compressor is securely parked at a safe distance from the excavation pit to prevent pit cave-in. Chock the wheels to prevent the compressor from rolling or falling into the pit. Maximum air pressure that can be delivered to the tool is 110 psi (7.6 bar). Do not exceed this pressure or damage to the tool, thereby voiding the tool warranty, or personal injury may result Safety Messages Catamount

19 PRECAUTIONS DURING OPERATION Two people are required to operate the boring tool. One person should always be outside the excavation pit and in control of the air supply to the tool in case of an emergency. The boring tool operator must monitor the tool to be sure that the air supply hose does not create an unsafe condition around the pit. Eye protection is necessary when using the boring tool. Avoid looking into the bore hole while the boring tool is in use. High pressure exhaust can eject dirt, stones, or other materials. Be careful when blowing out the hose. Aim the hose away from yourself and other persons. If the tool runs but does not move forward, turn off the air supply. Check to ensure the tool is not in contact with a gas line, waterline, electric line, or some other underground obstruction that can be damaged or cause personal injury. Do not override any safety controls on the tool or any support machinery. Shut down the unit at the fi rst sign of malfunction or hazardous condition. Do not disconnect the air supply without fi rst shutting off the air valve. Serious injury may result from the air under high pressure or from uncontrolled hose movement. DURING SERVICE Read and follow the service instructions in this manual before servicing the tool. Shut off the air supply valve and disconnect the air line before servicing the tool. Use only authorized parts for repair or replacement. These replacement parts, including bolts, are specified in this manual. Check the air supply hose periodically for damage to the hose or fi ttings. Never use the boring tool with damaged or worn air lines or fi ttings. This will minimize chances or air line breakage while in use. Catamount Safety Messages 10-19

20 Check and tighten loose hose clamps and clamp bolts regularly. Do not use a torch or welder on the boring tool. Applying heat may damage critical parts of the tool. Heating parts of the tool may alter the components strength and result in premature failure or personal injury. When the tailcone and rear anvil are removed, be careful when elevating the tool. The heavy striker inside the tool body may slide out. WARNING: Failure to follow any of the preceding safety instructions or those that follow within this manual, could result in serious injury or death. This manual is only to be used for those purposes for which it was intended as explained in this Operator s Manual Safety Messages Catamount

21 Section 11: Safety Decals General safety messages appear in this Safety Messages section. Specifi c safety messages are located in appropriate sections of the manual where a potential hazard may occur if the instructions nor procedures are not followed. INSPECTING SAFETY DECALS Safety decals located on your machine contain important and useful information that will help you operate your equipment safely. To assure that all decals remain in place and in good condition, follow the instructions given below: Keep decals clean. Use soap and water - not mineral spirits, abrasive cleaners, or other similar cleaners that will damage the decal. Replace any damaged or missing decals except the decal (Vermeer) located on the tool body. When attaching decals, the temperature of the mounting surface must be at least 40 F (5 C). The surface must also be clean and dry. When replacing a machine component with a decal attached, replace the decal also. Replacement decals can be purchased from your Vermeer equipment dealer.

25 Section 20: How the Catamount Piercing Tool Works The Active Head Power Port tools use pneumatic power to drive the striker inside the tool forward at a very high velocity. The striker then impacts the bit shaft at the front of the tool driving only the bit shaft forward into the soil. As the striker travels forward, ports in the rear of the striker pass by the valve opening an air passage to the front of the tool. This allows the air to be redirected and push the striker towards the rear of the tool. Before the striker has a chance to hit the rear anvil, the striker passes the ports again and redirects the air, forcing the striker forward again. The striker travels forward again striking the anvil in the nose of the tool and simultaneously driving the body forward and resetting the bit shaft. The Power Port Valve feature of the tool provides a 1/4 turn of the air supply hose to change the direction of the tool. Before the direction of the tool is changed, the air supply to the tool must be shut off. When the tool is placed into reverse, the valve timing is changed so that the forward stroke of the striker becomes shorter and the reverse stroke becomes longer. This allows the striker to impact the rear anvil and not the front anvil propelling the tool in the reverse direction. Catamount How it Works 20-25

IMPORTANT: When operating the tool for the fi rst time, add 1/2 oz (15 cc) of oil directly to the tool whip hose to provide lubrication during start-up. PRESSURE RELIEF Upon closing the ball valve (3) the oiler stops oiling and the tank is depressurized allowing for fi ll cap removal. All of the air must be drained out of the airhose before removing the fi ll cap. at the end of each use. 3 before adding oil to the reservoir. before disconnecting hoses. Catamount Oiler Controls 30-27

28 OIL - CHECK AND ADD Step 1: Turn off air supply. Allow air in hose to bleed out before removing fi ll plug. Step 2: Remove fi ll plug (4) and check/add oil (refer to Specifi cations Page ) IMPORTANT: Do not overfi ll the reservoir. The oiler requires a small air space to pressurize the oiler to force the oil into the air line. 4 Oiler - Adjust Screw (5) (inside the oiler) controls the amount of oil supplied to the tool. Remove the fi ll plug and use a screwdriver to turn the screw to adjust the rate of oil delivery. Fully CW... closed 3/8 Turn CCW from closed... lowest recommended rate 1 full turn CCW from closed...highest recommended rate To adjust: Step 1: Turn off air supply. 5 Step 2: Step 3: Remove fi ll plug (4) and turn the adjustment screw (5) with a slotted screwdriver. Use the chart below for proper settings for each particular size tool. 6 NOTE: It may take up to 30 minutes before a setting change is noticed in the tool.
