IMD LLC_____________________________________________________ 3 Intended Usage The intended usage of this PTO generator is the generation of electrical power. The IMD power generator can be used to feed electrical power into the circuit of a building (provided the proper electrical safety switch has been installed by a licensed electrician) or to plug appropriate electrical applications into its power outlets to operate them in case of a power outage.
IMD LLC_____________________________________________________ 4 In the event of a defect in material or workmanship during the 24 month period from the date of the original purchase, the manufacturer or its authorized dealer or repair center will, at the manufacturer’s sole discretion, repair or replace the product on the terms and conditions and with the limitations and exclusions as set forth below: 1.

IMD LLC_____________________________________________________ 6 Safety Instructions Read these operating instructions carefully, as well as those of the tractor and PTO shaft manufacturer. For safety reasons, you should not use the generator set until you have understood all the instructions. This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death.
IMD LLC_____________________________________________________ 7 General Safety Instructions Mechanical danger Operate the generator and tractor only when all protective devices have been installed properly and correctly. Before starting up the tractor, make sure that no one is standing in close proximity to the tractor or generator, particularly children. Watch out for children in particular because they tend to be attracted to machinery in operation.
IMD LLC_____________________________________________________ 8 Replace any damaged safety devices immediately and do not operate the equipment until such replacement is made. The PTO shaft safety guard must be able to rotate freely. Always wear close-fitting clothing, and tie back long hair. Avoid any contact of your hair or clothing with the rotating PTO shaft.
IMD LLC_____________________________________________________ 9 Never permit any unqualified person to install, operate or service this equipment. Authorized and trained personnel only! The installation and use of this generator must comply with all applicable codes and local, state and federal laws. Make sure to comply with the National Electric Code (NEC), Occupational Safety and Health Administration (OSHA) regulations, local industrial codes and local inspection requirements.
IMD LLC_____________________________________________________ 10 Preparing for use - Delivery conditions The power take-off generator is delivered fully assembled on a pallet. Before using the generator for the first time, fill the gearbox with gear oil according to specifications (see page 24) and fit the guard for the PTO shaft according to the instructions of the PTO manufacturer. Before lifting or moving the PTO generator, secure it safely against falling.
IMD LLC_____________________________________________________ 11 1. Choose a location and excavate the ground for a slab of the dimensions set forth in the diagram above. Excavate at least one foot = 12 inches (30.4 cm) deep and frame above ground sufficiently high enough that the height of the slab above the ground level is 17 inches (43.2 cm) below the centerline of the tractor’s PTO shaft (see dimension A in the diagram above). 2.
IMD LLC_____________________________________________________ 12 Optional Heavy Duty Trailer Using an IMD trailer is another option for increasing the stability and mobility of the PTO generator (see Accessories section page 27). Mounting the PTO generator on the trailer will give it sufficient stability so that it does not tip over during service and also allows it to be easily moved from one location to another. The trailer will be shipped disassembled. Basic tools are required for assembly.
IMD LLC_____________________________________________________ 13 Generator 3 wire AC Diagram 1. Main circuit breaker 2. Dual stator AC power windings The generator employs a stator assembly having a dual set of AC power windings and a 3wire AC connection system. Each stator AC power winding supplies 120 volts AC. When the two windings are connected in series, a 240 volt AC output results.
IMD LLC_____________________________________________________ 14 Installing PTO shaft If the guard for the power take-off shaft is not factory installed when the generator is shipped: The PTO shaft guard must be properly attached to the generator gearbox before the generator is started up. The PTO shaft end from the gearbox has a diameter of 1-3/8 inch and a 6-spline fitting (6-spline drive shaft). Push the PTO shaft onto the PTO shaft ends of the gearbox and tractor respectively, and engage.
IMD LLC_____________________________________________________ 15 Operation Switching ON Check the following every time before use: Is the generator securely attached to its concrete foundation or an approved device? Is the generator properly grounded? Are all safety devices fitted correctly? Is the PTO shaft fitted correctly between the tractor and the generator? Is there enough oil in the gearbox? Have the power cords of all electrical loads been disconnected from the generator? When operating
IMD LLC_____________________________________________________ 16 The generator supplies its power to the electrical loads. Check the frequency and/or Volt reading. If the frequency and/or voltage have fallen below their correct operating range: CAREFULLY Increase the tractor engine speed until the Hz meter indicates correct range again. Switching OFF Turn OFF the electrical loads (appliances). Set the generator Main Circuit Breaker to the OFF or OPEN position.
IMD LLC_____________________________________________________ 17 Visual Inspection Before switching on: Check all components of the unit for visible external damage or leakage. Check all electrical cables for loose contacts, broken insulations or signs of scorching Functional test After standing idle for long periods of time, the generator winding may corrode, reducing the efficiency.
IMD LLC_____________________________________________________ 18 Do not hose down the generator with water. Water can penetrate the generator stator and rotor windings, which could reduce insulation resistance. Possible generator failure may result. Clean the interior of the generator control panel in extreme harsh environmental conditions. The voltage regulator and electrical terminals especially must be kept clean. Check voltage regulator wires.
IMD LLC_____________________________________________________ 19 Long-term storage If the PTO generator is not used for a long period of time, do NOT store it outside or leave it exposed to the elements. The PTO generator should be stored in a dry clean environment protected from dust (e.g. warehouse). Observe the directions given for storage, because the air in barns may contain high levels of moisture or high concentrations of dust, or sometimes aggressive gases (e.g. ammonia).
