GENERATOR SET UP PLANNING THE POWER LOAD Plan your power load so that you do not exceed the generator’s rate capacity. To calculate the running and start-up wa age requirements for the devices you will be powering, follow the steps on page 18. SET UP THE PORTABLE POWER SOURCE This generator is designed to provide up to its max power (in wa s) of electrical power.
If your generator will be connected to your building’s system, it MUST ALWAYS BE isolated from the utility power grid with an approved transfer switch installed by a licensed electrician in compliance with all applicable building and electrical codes and in accordance with the guidelines supplied by your power company. There may be Federal or State Occupational Safety and Health Administration (OSHA) regulations, local codes or ordinances that apply to the intended use of the generator.
IMPORTANT: This generator is fitted with a MEN link cable, the neutral is internally bonded to the generator earth. When a licensed electrician is installing the generator to a building to be used as a backup power source, the MEN must be removed. The MEN link is located underneath the alternator end cap which is labelled to indicate its location. The MEN link cable is clearly labelled as “MEN link.
The location you choose to operate the generator must be OUTDOORS and away from all building air intakes. Never run the generator inside any closed or semi-enclosed spaces (even if outdoors), including homes, garages, basements, sheds or boxes. These spaces can trap poisonous gases, even if you run a fan or open windows. Ensure that working, battery-operated or battery back-up carbon monoxide alarms are used in any dwelling/structure that is in close proximity to the running operator.
canopy-like structure of heat-resistant material that is open on all sides. Make sure that all parts of the canopy are at least 2m from the exhaust and allow for adequate clearance above the generator so that heat does not build up. OPERATE AWAY FROM DUST/DIRT Do not use the generator in extremely dusty or dirty conditions. Excessive dust and dirt can cause premature failure of the machine.
POWER LOADING MANAGEMENT Your generator MUST BE SIZED PROPERLY to provide both the running and star ng (surge) wa age of the devices you will be powering. Before using your generator, determine the running and star ng wa age requirements of all the electrical devices you will be powering simultaneously. Following below are 4 simple stepts and an example on the right: Step 1 Step 2 Step 3 Step 4 Determine the tools and appliances you want to power at the same me.
STARTING THE ENGINE PRE-OPERATION CHECK 1. Check that all shields and covers are in place and all nuts, bolts and screws are htened. 2. Check the engine oil level. Add oil if low. Do not overfill. Running the engine without sufficient oil can cause irreparable damage. 3. Check fuel level. Add fuel if low (Fresh unleaded RON91) recommended. Star ng with a full tank will help to eliminate or reduce opera ng interrup ons for refuelling. Check fuel system components and lines for signs of leak. 4.
TO S TART T HE ENGINE 1. 2. 3. Disconnect all loads to the generator. Turn off the master switch to ensure that no electrical current is connected to the generator. Turn the fuel valve lever to the ON posi n. Wait for a minute for the fuel to enter the carbure or (for first me use). For cold engines, move choke lever to full choke posi on. To restart a warm engine, move choke lever to half choke or to RUN posi on. U S IN G KEY START T O START ENGINE 1. 2. 3.
ENGINE SPEED Engine speed has been factory set to provide safe operation. Tampering with the engine speed adjustment could result in the overheating of attachments and could cause a fire. CONNECTING LOADS You will want to be careful when connecting loads so as to not overload the generator, especially if you are powering devices with motors that require a higher starting power load. Instructions are provided below for connecting loads when you are using the generator as a portable power source.
CHARGING A BATTERY Remove the battery from the car, boat or any other device. The battery MUST be totally isolated from any other circuitry. After connection to the battery, RECHECK to ensure the connections are as below: Insert the T-shaped plug to the generator with the opposite end of the cable connected to the battery. Connect the positive (+) alligator clip (red) to the positive (+) terminal on the battery.
STOPPING T HE G E N E R ATOR Stop the engine using the following steps: 1. 2. 3. 4. 5. Turn off all appliances. Disconnect all loads to the generator. Never start or stop the generator with electrical devices plugged in or turned on. Allow the generator to idle for 2-3 minutes and cool down. Turn the engine switch to the OFF posi n. DO not leave the generator un it has completely stopped. Turn the RCBO switch to OFF posi on. Turn the fuel valve to OFF posi n.
STORAGE When you are finished using the generator, you must: Disconnect all loads Shut off fuel supply Disconnect spark plug and ba ery Store the generator properly Plan on opera ng the engine regularly unless the generator is prepared for longterm storage. DIS CONNECT L O A DS AND TU RN O F F THE FUEL S U P P L Y When you are finished using the generator, disconnect all loads and turn off fuel supply. Make sure all devices that were connected to the generator’s outlets have been disconnected.
OPERATE THE ENGINE REGULARLY The generator should be operated regularly to maintain the condition of internal parts. At least every four weeks, start the engine and let it run for 10 to 15 minutes with a small load plugged in such as a lamp or fan. Monthly operation of the generator will dry out any moisture that has accumulated in the windings which if left, can cause corrosion. It will also ensure that the unit is operating properly should it be needed in an emergency.
TRANSPORTING If the generator has been used, allow it to cool for at least 15 minutes before loading the generator on the transport vehicle. A hot engine and exhaust system can burn you and can ignite some material. Take care not to drop or strike the generator when transporting. Do not place heavy objects on the generator. When transporting the generator, turn the engine switch and the fuel valve lever OFF and keep the generator level to reduce the possibility of fuel leakage.
Allow the engine to cool completely before servicing the spark arrester. Remove the spark arrester, check and clean with a wire brush. Replace spark arrester if its damaged. KEEP GENERATOR CLEAN If dust or debris accumulates on the generator, clean the generator with a damp cloth or soft bristle brush. DO NOT allow air intakes to become blocked. Note: DO NOT spray generator with a garden hose or pressure washer. Water may enter the generator and cause damage to the rotor, stator or internal windings.
REPLACING FUEL FILTER Occasionally the fuel inline filter may become clogged and need replacing. Remove the fuel line from both sides of the filter by squeezing the ends of the retaining clip with pliers. Slide the fuel line off and replace with new fuel filter. reinstall fuel lines to new fuel filter.
