INTRODUCTION Thank You for Purchasing a PowerSmart® Product. This manual provides information regarding the safe operation and maintenance of this product. Every effort has been made to ensure the accuracy of the information in this manual. PowerSmart® reserves the right to change this product and specifications at any time without prior notice. Please keep this manual available to all users during the entire life of the generator.
GENERAL SAFETY PROCEDURES For any questions regarding the hazard and safety notices listed in this manual or on the product, please call (800) 791-9458 Mon-Fri 9-5 EST before using the generator. DANGER: CARBON MONOXIDE Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide (CO). This is a poison gas you cannot see or smell. If you can smell the generator exhaust, you are breathing CO. But even if you cannot smell the exhaust, you could be breathing CO.
WARNING: This generator produces heat when running. Temperatures near exhaust can exceed 1500F (650 C). Do not touch hot surfaces. Pay attention to warning labels on the generator identifying hot parts of the machine. Allow generator to cool down after use before touching engine or areas of the generator that become hot during use. CAUTION: Misuse of this generator can damage it or shorten its life. Only use generator for its intended purposes. Operate only on dry, level surfaces.
KNOWING YOUR GENERATOR Use the illustrations below to become familiar with the locations and functions of the various components and controls of this generator.
PREPARATION The following section describes steps necessary to prepare the generator for use. If after reading this section, you are unsure about how to perform any of the steps please call (800) 791-9458 Mon-Fri 9-5 EST for customer service. Failure to perform these steps properly can damage the generator or shorten its life. Step 1 - SETUP WHEEL KIT WARNING: This generator is heavy. Assembly procedures may require lifting equipment or two people.
To add oil, follow these steps: 1. Make sure the generator is on a level surface. Tilting the generator to assist in filling will cause oil to flow into engine areas and will cause damage. Keep generator level! 2. Remove the dipstick from the engine. 3. Add oil slowly as to not overflow the unit. 4. To check the oil level, wipe the dipstick with a clean rag. Insert the dipstick into the oil fill opening without screwing it in. Remove the dipstick to check the oil mark. 5.
Step 4 - GROUND THE GENERATOR WARNING: Failure to properly ground the generator can result in electrocution. Ground the generator by tightening the grounding nut on the front control panel against a grounding wire. A generally acceptable grounding wire is a No. 12 AWG (American Wire Gauge) stranded copper wire. This grounding wire should be connected at the other end to a copper, brass, or steel-grounding rod that is driven into the earth. Wire and grounding rods are not included in generator contents.
STARTING THE GENERATOR Before starting the generator, make sure you have read and performed the steps in the “Generator Preparation” section of this manual. If you are unsure about how to perform any of the steps in this manual, please call (800) 791-9458 Mon-Fri 9-5 EST for customer service. DANGER: CARBON MONOXIDE. Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide (CO). This is a poison gas you cannot see or smell.
MANUAL START THE ENGINE To manual start the generator, perform the following steps: 1. Unplug all electrical devices from the generator during ignition. Otherwise it will be difficult for the engine to start. 2. Check that the generator is properly grounded (Refer to “GROUND THE GENERATOR”). 3. Check the oil and fuel levels. 4. Turn the fuel valve to the “ON” position. 5. Move the choke lever to the “CLOSE” position. 6. Set the ON/OFF Switch to the “ON” position. 7.
STOPPING THE GENERATOR TO STOP THE GENERATOR 1. Turn off all electrical devices prior to unplugging them from the generator. Unplugging running devices can cause damage to the generator. 2. Turn the “ON/OFF” switch to the “OFF” position. 3. Turn the fuel valve to the “OFF” (horizontal) position. WARNING: Allow the generator to cool for several minutes before touching areas that become hot during use.
should be listed somewhere on the device or in its instruction manual. If this wattage cannot be found, calculate it by multiplying the Voltage requirement by the Amperage drawn: Watts = Volts x Amperes If these specifications are not available, estimate the wattages requirement of the device by using the chart in next page. When the rated wattage requirement of each electrical device has been determined, add these numbers to find the total rated wattage needed.
SOME NOTES ABOUT POWER CORDS Long or thin cords can drain the power provided to an electrical device by the generator. When using such cords, allow for a slightly higher rated wattage requirement by the electrical device. See below for recommended cords based on the power requirement of the electrical device.
Check the oil level of the generator according to the Recommended Maintenance Schedule above. The generator is equipped with an automatic shutoff to protect it from running on low oil. This is a critical step for proper engine starting. To check the oil level: 1. Make sure the generator is on a level surface. 2. Clean around oil fill. Remove dipstick and wipe the dipstick with a clean rag. Insert the dipstick into the oil fill opening without screwing in. Remove the dipstick to check the oil mark.
2. Remove the sponge-like element from the casing. 3. Wipe the dirt from inside the empty air cleaner casing. 4. Wash the sponge-like element in household detergent and warm water. Small amount of oil in the element is normal and necessary for the engine to work properly. 5. Reinstall the sponge-like element in the air cleaner casing and reinstall the cover. CAUTION: running the engine with dirty, damaged or missing air cleaner element will cause the engine to wear out prematurely.
DRAINING THE FUEL TANK Clean fuel tank each year or before storing the generator for extended periods of time. To drain the fuel tank and carburetor: 1. Turn the fuel valve to the “OFF” position. 2. Remove the fuel line between the fuel valve and carburetor. Caution: A small amount of fuel may leak from the hose during removal. 3. Attach a fuel line (not included with the generator) to the exposed end of the fuel valve. 4.
HIGH ALTITUDE OPERATION ABOVE 3000 FEET The fuel system on this generator may be influenced by operation at higher altitudes. Proper operation can be ensured by installing an altitude kit at altitudes higher than 3000 feet above sea level. At elevations above 8000 feet, the engine may experience decrease performance, even with the proper main jet. Operating this generator without the proper altitude kit installed may increase the engine’s emissions and decrease fuel economy and performance.
STORAGE & TRANSPORT PROCEDURES CAUTION: Never place any type of storage cover on the generator while it is still hot. If the generator is being stored for short periods of time (30 to 60 days), add stabilized fuel to the fuel tank until full. NOTE: Filling the tank reduces the amount of air in the tank and helps reduce deterioration of fuel. Run the engine for 2 – 3 minutes allowing stabilized fuel mixture to circulate through the carburetor.
