Before Starting the Engine
General
After correct installation of the unit and the wiring, the generating set must be fully checked over before first
starting can be attempted. Points to check include:
• Check all belts, guards and panel covers are firmly secured.
• Check the installed wiring to ensure all connections are firmly installed in the correct position, and that
wires are in good condition.
• Ensure that the machine exhaust/silencer has been correctly fitted and all connections are secure.
• Connect battery cables. Ensure battery connections are secure and polarity of connections are correct.
• Ensure that there is fuel in the fuel tank.
• If the machine has not been run previously, if it has run out of fuel or if the fuel supply has been reconnected
then the fuel system must be primed prior to starting. Check for fuel leaks during this process.
• Check level of coolant in machine radiator, and top-up if low.
• Check hoses for damage or loose clamps.
• Check level of engine oil using dipstick.
• Check fuel filter/water separator for presence of water or contaminants.
• Visually inspect the engine and alternator for any signs of damage, water, oil or fuel leaks.
• Ensure that machine intake and outlet air vents and grills are not obstructed or blocked in any way to
allow good airflow through the machine.
• Check that the engine intake air filter is correctly fitted, and that there are no obstructions to the incoming
air.
• Ensure that all supplied documentation packs have been removed from the machine.
• Ensure that the alternator windings and assembly are not damp, or dirty. Failure to do so could result in
damage to the alternator windings. If windings are observed to be damp/dirty contact your JCB Dealer.
• With the exception of emergency power generators, the engine should be warmed up with a reduced load
before applying the full load.
Checks After Running
Ensure that the electrical load is switched OFF before stopping the engine.
• Check that the power is cut from the battery master switch and that the control switch is in the "0" position.
• Fill the fuel tank. Make sure that the filler cap and the area round the filler opening are clean to avoid
contamination of the fuel.
• If there is a risk of freezing, the cooling system must contain the correct antifreeze.
• At temperatures below 0°C: Prepare for the next start by connecting the engine heater.
Coolant should be topped up when the engine is stopped after the first start.
